To correct the primary cause of the alarm, verify that there is no conflict in port assignment with other processes in the system and ensure that no previous instance of the same process is still running. The secondary cause of the alarm is that a software logic problem has occurred. To correct the secondary cause of the alarm, contact Cisco TAC.

Media Gateway Control Protocol

The Socket Failure alarm is issued when there is a failure in creating the UDP port used by the MGCP stacks. Some other application might already be active on the same UDP port and IP address to which the Call Agent MGCP stack is assigned. Reconfigure the MGCP stack to use a free UDP port.

Session Initiation Protocol

The Socket Failure alarm is issued when there is a failure in creating the UDP port used by the SIA process. Some other application might already be active on the same UDP port and IP address to which the SIA process is assigned. Reconfigure the SIA port to use a free port or the SIP default port 5060.

Session Initiation Protocol Message Receive Failure—Signaling (8)

The Session Initiation Protocol Message Receive Failure alarm (major) indicates that a SIP message receive has failed. The primary cause of the alarm is that Operating System level network errors have occurred or the network configuration is invalid. To correct the primary cause of the alarm, have the network administrator resolve the network errors. Contact Cisco TAC if you need assistance. Manually clear alarm. Restart this call agent instance using the platform start command.

Session Initiation Protocol

The SIP Message Receive Failure alarm is issued when SIP messages cannot be received. This could be due to port conflict (two processes attempting to use the same UDP port). Examine the HOSTNAME field in the alarm report to determine the IP address or domain name of the Call Agent that generated this alarm. Telnet into this Call Agent instance as a root user. In this Call Agent, configure another UDP port for the SIA process to avoid port conflict, by setting the SIA port in platform.cfg file to another port number. Call Cisco TAC if you need assistance. Restart this Call Agent instance using the platform start command.

Timeout on Internet Protocol Address—Signaling (9)

The Timeout on Internet Protocol Address alarm (major) indicates that an IP address has timed out. The alarm is issued when the OptiCall is unable to communicate with a gateway. To correct the primary cause of the alarm, verify that the gateway is both configured for service and that it has been set in service. Attempt to ping the gateway using the IP address from the Event Report. If the ping is not successful, then diagnose the issue that prevents the address from being reached. Use the Status MGW ID=xxx, where xxx is the IP address given in the Event Report. If the status is not INS, then use the control mgw command to put it in service.

Media Gateway Control Protocol

The Timeout on IP Address alarm is issued when the Cisco BTS 10200 is unable to communicate with a gateway. Verify that the gateway is configured for service and that it has been set in service.

Signaling System 7 Signaling Link Down—Signaling (13)

The Signaling System 7 Signaling Link Down alarm (major) indicates the SS7 signaling link is down. The primary cause of the alarm is that the SS7 trunk group may be out-of-service (OOS). To correct the primary cause of the alarm, use the control ss7-trunk-grp command to place the trunk group in service (INS). The secondary cause of the alarm is that the local Ulticom stack may be down. To correct the secondary cause of the alarm, run the Ulticom stack command again. The ternary cause of the alarm is that the SS7 link may be disconnected or faulty. To correct the ternary cause of the alarm, check the Ulticom local configuration. The subsequent cause of the alarm is that the remote SS7 signaling site may be down or incorrectly configured. To correct the subsequent cause of the alarm, check the Ulticom remote configuration.

Signal System 7 and Call Agent Fail-Over Interaction

When an ISUP SS7 signaling link goes into the link failure state, a Signaling System 7 Signaling Link Down alarm (13) is activated and the call-agent will begin a 120 second timer. When the SS7 signaling link is restored, in-progress calls are cleared if they were in a transient state, if an event occurred that required the sending of an ISUP message during the link failure, or if the 120 second timer has expired.

Should the call-agent fail over for any reason, the state of the 120 second timer or any indication of a request for an outgoing message that could not be sent will not be preserved. If the signaling links are in the failure state on the stand-by side, the 120 second timer will be restarted; however, if the links should restore prior to that the timer expiry, any stable calls will not be cleared.

This applies should multiple fail-overs occur prior to eventual signaling link restoration. In these situations, if a call clearing event has been missed, any calls remaining up will be cleared by the normal ISUP network recovery and message retransmission mechanisms.

Destination Point Code Unavailable—Signaling (23)

The Destination Point Code Unavailable alarm (major) indicates that the specified DPC is not available. This alarm indicates that the Cisco BTS 10200 is unable to communicate with the specified DPC in the SS7 network. Use these steps to determine if the issue is a communication problem between the Cisco BTS 10200 and the IP transfer point (ITP) or if it is related to communication problems between the ITP and the DPC:

Step 1 Use the Cisco BTS 10200 CLI show alarm command to determine if there is an active Signaling Gateway Group Out of Service alarm. This will occur if communication has been lost to at least one of the SGs in the SG-Group. If so, proceed to the "Signaling Gateway Group Is Out of Service—Signaling (110)" section. Otherwise, proceed to Step 2.

Step 2 Determine if there is an M3UA Cannot Go Active alarm. This occurs if, at the time of startup or failover, the Cisco BTS 10200 is not able to communicate with any of the SGs. If this is the case, proceed to the "Message Transfer Part 3 User Adapter Cannot Go Active—Signaling (122)" section. Otherwise, proceed to Step 3.

Step 3 If you arrive at this step, there is probably communication between the Cisco BTS 10200 and ITP at the M3UA and SCCP user adapter (SUA) layers, and a communication problem exists between the ITP and the unavailable DPC. To confirm this, log on to each ITP, get into enable mode, and enter show cs7 route. The output of this command tells you if the associated DPC is accessible or not from the ITP point of view and will look similar to the following:

va-2651-82# show cs7 route

Destination            Prio Linkset Name        Route

---------------------- ---- ------------------- -------

229.123.2/24     INACC   1  lset1chn            UNAVAIL

This output indicates that DPC 229.123.2 is unavailable from the ITP point of view.

Step 4 Determine if the problem is at the link level or at a higher level outage in the DPC by typing show cs7 linkset. If the ITP shows that the DPC is AVAIL, there is a mismatch between the ITP and Cisco BTS 10200. Please contact the Cisco TAC.

Step 5 Check whether the DPC has been removed from the Cisco BTS 10200 database. At the Cisco BTS 10200 CLI prompt, enter show call-ctrl-route or show sccp-route and see if the DPC is in any of the routes. If not, the alarm was raised before the associated routes were deleted. If this is the case, manually clear the alarm.

Step 6 If you still cannot determine the cause of the problem, contact the Cisco TAC.

Destination Point Code Congested—Signaling (24)

The Destination Point Code Congested alarm (minor) alarm indicates that the specified DPC is congested. This alarm indicates that the DPC in the SS7 network is congested, that is, is in a state where it has received more traffic than it can handle. This should be a temporary state. If the type of network is National, which is generally the case in the United States, there will also be a level of congestion associated with the alarm.

The ITP should continually communicate with the DPC in the SS7 network to determine if congestion has abated. If this alarm does not clear or keeps reappearing after clearing, contact your SS7 service provider to determine why the DPC is congested.

The DPC Congested alarm is issued when the specified destination point code is congested. Monitor event reports at the network level to determine if the traffic load to the specified DPC is too high on the local end, or if the remote end is lagging in processing the traffic.

To troubleshoot the M3UA or the SUA layers, use the following procedures.

Message Transfer Part 3 User Adapter Troubleshooting Procedure

Use the following steps to determine the source of the problem at the M3UA layer:

Step 1 Determine if the administrative state of the SCTP is correct.

a. Type the following command at the Cisco BTS 10200 CLI prompt:

status sctp-assoc id=<sctp-assoc-name>

If the response displays administrator state ->ADMIN_OOS, the SCTP association has been taken administratively out of service and needs to be put back in service.

b. Enter the following command to put the SCTP association in service:

control sctp-assoc id=<sctp-assoc-name>; mode=forced; target-state=ins;

c. If the administrative state is ADMIN_INS, determine if the association has been taken out of service on the ITP. Log on to the ITP. If you are unable to log on to the ITP, proceed to Step 2.

d. If you are able to log on to the ITP, check the state of the associated application service provider (ASP) by entering the following command:

show cs7 asp

The following is an example of the output:

ASP Name      AS Name       State     Type  Rmt Port Remote IP Addr  SCTP

------------  ------------  --------  ----  -------- --------------- ----------

hrn11asp      hrn11bts      shutdown  M3UA  11146    10.0.5.13

e. If the state of the ASP indicates shutdown, someone has administratively taken the association out of service. Refer to the Cisco ITP User's Guide, at the following universal resource locator (URL), to put the ASP (SCTP association) back in service:

http://www.cisco.com/en/US/products/sw/wirelssw/ps1862/tsd_products_support_series_home.html

f. If the state is down proceed to Step 2.

g. If the state of the ASP is inactive, the ASP is probably on the standby Cisco BTS 10200. If the ASP on the active Cisco BTS 10200 is inactive, proceed to Step 7.

Step 2 Determine if the problem is an IP address or port configuration mismatch between the ITP and the Cisco BTS 10200.

a. Determine the Cisco BTS 10200 configured values for the Cisco BTS 10200 IP addresses and port. Look for the DNS name and port number that are configured for the SGA process in /opt/OptiCall/CA146/bin/platform.cfg. Go to the specified directory and enter

cat platform.cgf | grep mdl

The output will look similar to the following:

Args=-t 1 -h mgcp-HRN11CA.hrndevtest.cisco.com -p 11146 -mdldir. /mdl -mdltracedir 
../mdltrace -mdltestmode 0 -mdlloadmdo 0 -mdltriggertimer 200 -mdlgarbagetimer 5146 
-resetcics 1 -fcmtimer 900 -fcmparalleljobs 4

–The local IP port number is shown directly after the -p option.

–The local IP addresses that are used by the Cisco BTS 10200 are derived from the DNS name, which is given directly after the -h option. At the Cisco BTS 10200 UNIX prompt, enter

NSlookup <DNS name>

The output will look similar to the following:

Server:  hrnbtsjs-1.cisco.com

Address:  10.82.70.199

Name:    mgcp-HRN11CA.hrndevtest.cisco.com

Addresses:  10.0.5.136, 10.128.1.147

The Cisco BTS 10200 configured local IP addresses are given in the Addresses: line.

b. Determine the ITP configured values of the ITP Cisco BTS 10200 IP addresses and port.

–Log on to the ITP and get into enable mode.

–Enter the following command:

show run

–Hit enter until the ASP configurations are displayed. A section similar to the following will appear which shows you the ITP configured values for the Cisco BTS 10200 IP addresses of the SCTP association:

cs7 asp hrn11asp 11146 2905 m3ua

remote-IP 10.0.5.136

remote-IP 10.128.1.147

The number after the ASP name "hrn11asp" is the port number that the ITP has configured for the Cisco BTS 10200 side of the SCTP association. The two remote-IP addresses are the addresses that the ITP has configured for the Cisco BTS 10200 side of the SCTP association. Make sure all of these values match the values found in Step 2A.

c. Determine the Cisco BTS 10200 configured values for the ITP IP addresses and port.

On the Cisco BTS 10200 EMS CLI console, type the following:

CLI> show sctp-assoc id=<SCTP assoc id>

The output shows the IP addresses and port. For example:

REMOTE_PORT=2905

REMOTE_TSAP_ADDR1=10.0.1.54

REMOTE_TSAP_ADDR2=10.128.1.239

d. Determine the ITP configured values of the ITP Cisco BTS 10200 IP addresses and port.

–Log on to the ITP and get into enable mode.

–Enter sho run.

–Press Enter until the m3ua (or sua) configuration is displayed. In our example, we are considering the SCTP association connection between the Cisco BTS 10200 and the ITP, so we will look at the ITP m3ua configuration. For example:

cs7 m3ua 2905

local-IP 10.0.1.54

local-IP 10.128.1.239

–Make sure that the IP addresses and port number are the same values as found in step 2C.

Step 3 Determine if all Ethernet connections on the Cisco BTS 10200 have been disconnected or if communication has been lost to the IP router. In the platform.log, look for the following ERROR message:

"All the IP interfaces are faulty!!"

If this message is found, the Ethernet connections of the Cisco BTS 10200 have been pulled or cut. If this message is not found, proceed to Step 4.

Step 4 Determine if the problem is an IP routing issue.

a. Determine what has been provisioned in the Cisco BTS 10200 for the destination IP interfaces of the SCTP association by typing the following command:

show sctp-association id=<sctp-association-id>

Information similar to the following will appear and display the destination IP addresses:

REMOTE_TSAP_ADDR1=10.0.1.54

REMOTE_TSAP_ADDR2=10.128.1.239

b. Ping each of the destination IP addresses. If one of the addresses does not respond to the ping, there is an IP routing problem that has disabled SCTP communication. Contact the Cisco TAC for assistance. If the ping commands are successful, proceed to Step 5.

Step 5 Determine if the Cisco BTS 10200 is reachable from the ITP.

a. Log on to the ITP and get into enable mode.

b. Find the Cisco BTS 10200 SCTP association endpoint IP addresses by typing the following command:

show run

c. Press Enter until the ASP configuration is displayed. A section similar to the following will display the Cisco BTS 10200 IP addresses of the SCTP association:

cs7 asp hrn11asp 11146 2905 m3ua

remote-IP 10.0.5.136

remote-IP 10.128.1.147

d. Ping each of the IP addresses. If you do not receive a response to the ping command for at least one of the Cisco BTS 10200 IP endpoint addresses, there is an IP routing problem that is causing the SCTP association to be down. Contact the Cisco TAC for assistance. Otherwise, proceed to Step 6.

Step 6 Bounce the SCTP association (take it administratively out of service and then put it in service).

a. At the Cisco BTS 10200 CLI prompt, enter the following commands:

control sctp-assoc id=<sctp-assoc-name>; mode=forced; target-state=oos;

control sctp-assoc id=<sctp-assoc-name>; mode=forced; target-state=ins;

b. Check if the SCTP association has come back in service by entering the following:

status sctp-assoc id=<sctp-assoc-name>;

The output shows either operator state -> SCTP-ASSOC out of service or operator state -> SCTP-ASSOC in service.

If the operator state still shows that the SCTP association is out-of-service, proceed to Step 7.

Step 7 Bounce the SCTP association from the ITP side by performing the following steps:

a. Log on to the ITP and get into enable mode.

b. Get into configure mode by typing configure terminal.

c. Type the following commands to bounce the SCTP association back in service:

va-2651-82(config)#cs7 asp hrn11asp

va-2651-82(config-cs7-asp)#shut

va-2651-82(config-cs7-asp)#no shut

va-2651-82(config-cs7-asp)#end

d. Determine if the SCTP association has come back in service by typing the following Cisco BTS 10200 CLI command:

status sctp-assoc id=<sctp-assoc-name>;

The output displays either operator state -> SCTP-ASSOC out of service or operator state -> SCTP-ASSOC in service.

If the operator state still shows that the SCTP association is out-of-service, there is probably an SCTP communication issue that must be debugged at the SCTP protocol level. Contact the Cisco TAC for assistance.

Signaling Connection Control Part User Adapter Troubleshooting Procedures

Refer to Chapter 13, "Network Troubleshooting" to determine the source of the problem at the SUA layer.

Signaling Gateway Group Is Out of Service—Signaling (110)

The Signaling Gateway Group is Out of Service alarm (major) indicates that the signaling gateway group is out-of-service. The primary cause of the alarm is that all the SCTP associations between the CA and the SGs are out-of-service. To correct the primary cause of the alarms, make sure that all Ethernet connections on the CA and SGs are plugged in. Also make sure all associated IP routers are operational. The secondary cause of the alarm is that the M3UA layer is down between the CA and SGs. To correct the secondary cause of the alarm, use a snooper application to determine why the M3UA layer is down.

This alarm indicates that after communication to the SG group was established, it was lost. This indicates that communication to associated SGs is down, which also indicates that communication to all SGPs is down. See the "Signaling Gateway Failure—Signaling (113)" section to determine why the associated SGs are down.

Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down)—Signaling (111)

The Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down) alarm (major) indicates that the SCTP association is degraded. The primary cause of the alarm is that a single Ethernet connection on CA or SGP is unplugged or severed. To correct the primary cause of the alarm, plug in all Ethernet connections or repair if severed. The secondary cause of the alarm is a SCTP communication problem—or protocol timeout. To correct the secondary cause of the alarm, use a snooper application to determine why the SCTP association is degraded.

Message Transfer Part 3 User Adapter Troubleshooting Procedure

This alarm indicates that one of the two sides of the multi-homed SCTP connection is down. Communication still exists if the other side of the multi-homed connection is up. Refer to the "Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down)—Signaling (111)" section, or contact the Cisco TAC for assistance in resolving this issue.

Signaling Connection Control Part User Adapter Troubleshooting Procedure

This is either an IP routing problem or an ITP Ethernet port hardware failure. Change the hardware immediately, if it is a hardware failure, to prevent dual outage of the ITP's IP communication.

Stream Control Transmission Protocol Association Configuration Error—Signaling (112)

The Stream Control Transmission Protocol Association Configuration Error alarm (minor) indicates that an SCTP association configuration error has occurred. The primary cause of the alarm is that the destination IP address is invalid. To correct the primary cause of the alarm, input a new destination IP address; see the log for additional details. The secondary cause of the alarm is that the local IP address is invalid. To correct the secondary cause of the alarm, input new local IP address information. The ternary cause of the alarm is that the IP Routing table is not configured properly. To correct the ternary cause of the alarm, have the system administrator configure IP routing table.

Message Transfer Part 3 User Adapter Troubleshooting Procedure

This alarm indicates that there is a provisioning error keeping the Cisco BTS 10200 from properly configuring the SCTP association. Perform the following steps to resolve the problem:

Step 1 To get more information about this alarm, look at the platform.log for error messages containing the string "Multipurpose Internet Mail (MIM) configuration (CFG)."

Step 2 Perform Step 2 of the "Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down)—Signaling (111)" section to verify that your IP addresses and ports are properly configured on the Cisco BTS 10200.

Step 3 Contact the Cisco TAC for assistance in resolving this issue.

Signaling Connection Control Part User Adapter Troubleshooting Procedure

Refer to Chapter 13, "Network Troubleshooting" to verify that the IP addresses and ports are properly configured on the Cisco BTS 10200.

Signaling Gateway Failure—Signaling (113)

Note When a port on an ITP is removed from service by use of the shut command, multiple Signaling 113 and 114 alarms are raised (on status). When the port is recovered, through cycling of the ITP power, all alarms raised are cleared (off status) and are removed from CURRENT_ALARM table. However, not all cleared alarms (off status) are displayed on the subscriber terminal. Only the first instance of the cleared alarms (off status) with a variation in type, number, and component-ID is displayed. Multiple instances of the cleared alarms (off status) where the type, number, and component-ID are identical are not displayed.

The Signaling Gateway Failure alarm (major) indicates that all associated signaling gateway processes are out-of-service. The primary cause of the alarm is that all associated Signaling Gateway Processes are out-of-service. To correct the primary cause of the alarm, determine why each associated Signaling Gateway Process is out-of-service.

This alarm indicates that communication at the M3UA layer to an SG has failed. M3UA communications at all SGPs that make up the SG are unavailable. See the "Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down)—Signaling (111)" section to determine why the associated SGPs are down.

Signaling Gateway Process Is Out of Service—Signaling (114)

The Signaling Gateway Process is Out of Service alarm (major) indicates that all SCTP associations between the SGP and the CA are out of service. The primary cause of the alarm is that all SCTP associations between the SGP and the CA are out-of-service. To correct the primary cause of the alarm, see the SCTP Association Alarm definition to determine how to rectify the problem. The secondary cause of the alarm is that the M3UA layer is down between the CA and the SGP. To correct the secondary cause of the alarm, use a snooper utility to determine why the M3UA layer is down. Also see the log for additional information.

This alarm indicates that communication at the M3UA layer to an SGP has failed. In the majority of cases, there will also be a related SCTP Association Failure alarm. If this is the case, proceed to the "Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down)—Signaling (111)" section. Otherwise, the problem is at the M3UA layer. Call the Cisco TAC for assistance.

Destination Point Code User Part Unavailable—Signaling (116)

The Destination Point Code User Part Unavailable alarm (major) indicates that a layer 4 user part, such as ISUP, is unavailable at the DPC in the SS7 network. The primary cause of the alarm is that the SGP sent a DUPU M3UA message to the CA indicating that a user part is unavailable on a DPC. To correct the primary cause of the alarm, contact the SS7 network administrator to report the user part unavailable problem related to the DPC so communication can be restored.

Circuit Validation Test Message Received for an Unequipped Circuit Identification Code—Signaling (117)

The Circuit Validation Test Message Received for an Unequipped Circuit Identification Code alarm (minor) indicates that a CVT message was received for an unequipped CIC. The primary cause of the alarm is that the CIC is not provisioned. To correct the primary cause of the alarm, provision the CIC.

Circuit Verification Response Received With Failed Indication—Signaling (118)

The Circuit Verification Response Received With Failed Indication alarm (minor) indicates that a CVR message was received with a failure indication. The primary cause of the alarm is that a CIC mismatch has occurred. To correct the primary cause of the alarm, perform an internal test such as checking that the CIC is assigned to a circuit between the sending and the receiving switch.

Signaling System 7 Adapter Process Faulty—Signaling (119)

The Signaling System 7 Adapter Process Faulty alarm (critical) indicates that a S7A process is faulty. The primary cause of the alarm is that an OMNI or a S7A exception has occurred. To correct the primary cause of the alarm, check OMNI process. The S7A process will restart itself if the S7A maximum restart threshold has not been exceeded.

Signaling System 7 Module/Signaling System 7 Adapter Faulty—Signaling (120)

The Signaling System 7 Module/Signaling System 7 Adapter Faulty alarm (critical) indicates that the S7M/S7A processes are faulty. The primary cause of the alarm is that an OMNI failure has occurred. To correct the primary cause of the alarm, check the OMNI status. An automatic failover will occur in a duplex configuration.

Message Transfer Part 3 User Adapter Cannot Go Standby—Signaling (121)

The Message Transfer Part 3 User Adapter Cannot Go Standby alarm (major) indicates that the M3UA process cannot go into standby mode. The primary cause of the alarm is that no inactive ACK messages are being received from any Signaling Gateway. The SG or SCTP associations are probably down. To correct the primary cause of the alarm, investigate other alarms to see if SGs are down or if SCTP associations are down. Take corrective action according to those alarms.

This alarm is raised at initial startup or during failover by the Cisco BTS 10200 node that is trying to go into platform Standby mode. See the "Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down)—Signaling (111)" section to determine why the Cisco BTS 10200 is unable to communicate with any of the SGs at the M3UA layer. See the "Check the Stream Control Transmission Protocol Association Status" section on page 13-3 to determine why the Cisco BTS 10200 is unable to communicate with any of the ITPs at the SUA layer.

Message Transfer Part 3 User Adapter Cannot Go Active—Signaling (122)

The Message Transfer Part 3 User Adapter Cannot Go Active alarm (major) indicates that the M3UA process cannot go into active mode. The primary cause of the alarm is that no active ACK messages are being received from any Signaling Gateway. The SG or SCTP associations are probably down. To correct the primary cause of the alarm, investigate other alarms to see if SGs are down or if the SCTP associations are down. Take corrective action according to those alarms.

This alarm is raised at initial startup or during failover by the Cisco BTS 10200 node that is trying to go into platform Active mode. It occurs when this Cisco BTS 10200 node is unable to communicate properly with any SGs to tell them that all active call traffic should be routing towards the Cisco BTS 10200. See the "Stream Control Transmission Protocol Association Degraded (One of Two Internet Protocol Connections Down)—Signaling (111)" section to determine why the Cisco BTS 10200 is unable to communicate with any of the ITPs at the M3UA layer. Refer to the "Check the Stream Control Transmission Protocol Association Status" section on page 13-3 to determine why the Cisco BTS 10200 is unable to communicate with any of the ITPs at the SUA layer.

Remote Subsystem is Out Of Service—Signaling (124)

The Remote Subsystem is out of Service alarm (minor) indicates that the remote subsystem is out-of-service. The primary cause of the alarm is that the link lost connection or the remote subsystem is out-of-service. To correct the primary cause of the alarm, contact your service control point (SCP) service provider for assistance.

Note This alarm can occur when there is an SS7 outage affecting a nonadjacent remote destination point code (DPC) where the global title translation (GTT) database resides. The SS7 SCP subsystems in the Cisco BTS 10200 show the allowed status but the related DPC is shown to be unavailable.

Signaling Connection Control Part Routing Error—Signaling (125)

The Signaling Connection Control Part Routing Error alarm (major) indicates that the SCCP route was invalid or not available. The primary cause of the alarm is that the SCCP route is invalid or is not available. To correct the primary cause of the alarm, provision the right SCCP route.

Signaling Connection Control Part Binding Failure—Signaling (126)

The Signaling Connection Control Part Binding Failure alarm (major) indicates that the SCCP binding failed. The primary cause of the SCCP Binding Failure alarm is that the Trillium stack binding failed. To correct the primary cause of the alarm, reinitialize the TSA process or remove the subsystem from the EMS table and add it again.

Transaction Capabilities Application Part Binding Failure—Signaling (127)

The Transaction Capabilities Application Part Binding Failure alarm (major) indicates that the TCAP binding failed. This alarm is raised when the TCAP layer does not have enough service access points (SAPs) to bind for the subsystem. Currently only 16 subsystems are allowed on the same platform. Check the Subsystem table to see if you have more than 16 subsystems on the same platform; such as, Feature Server for POTS, Tandem, and Centrex services (FSPTC) or Feature Server for AIN services (FSAIN). The primary cause of the TCAP Binding Failure alarm is that the Trillium stack binding failed. To correct the primary cause of the alarm, reinitialize the TSA process or remove the subsystem from the EMS table and add it again.

Session Initiation Protocol Trunk Operationally Out-of-Service—Signaling (142)

The Session Initiation Protocol Trunk Operationally Out-of-Service alarm (critical) indicates that the SIP trunk is operationally out-of-service. The primary cause of the alarm is that the Cisco BTS 10200 is unable to communicate with a remote SIP party (Call-Agent or Proxy) over a SIP or SIP-T trunk. To correct the primary cause of the alarm, verify that the DNS resolution exists, if the TSAP address of the remote entity is a domain name. Verify that the remote entity is reachable by ICMP ping, using the Trunk TSAP address from the alarm event report. If the same alarm is reported on all the softswitch trunk groups, then verify that the network connection is operational. If the ping is not successful, then find out what is preventing the TSAP address from being reached. Verify that the SIP application is running on the remote host and listening on the port specified in the TSAP address.

Internet Protocol Interface Link to the Signaling System 7 Signaling Gateway Is Down—Signaling (143)

The Internet Protocol Interface Link to the Signaling System 7 Signaling Gateway Is Down alarm (minor) indicates that an IP interface link to the SS7 signaling gateway is down. The primary cause of the alarm is an interface hardware problem. To correct the primary cause of the alarm, check the link interfaces.

All Internet Protocol Interface Links to Signaling System 7 Signaling Gateway Are Down—Signaling (144)

The All Internet Protocol Interface Links to Signaling System 7 Signaling Gateway Are Down alarm (critical) indicates that all IP interface links to the SS7 signaling gateway are down. The primary cause of the alarm is an interface hardware problem. To correct the primary cause of the alarm, check the link interfaces.

One Internet Protocol Interface to Signaling System 7 Signaling Gateway Is Down—Signaling (145)

The One Internet Protocol Interface to Signaling System 7 Signaling Gateway Is Down alarm (minor) indicates that one IP interface link to the SS7 signaling gateway is down. The primary cause of the alarm is an interface hardware problem. To correct the primary cause of the alarm, check the link interfaces.

Stream Control Transmission Protocol Association Congested—Signaling (150)

The Stream Control Transmission Protocol Association Congested alarm (minor) indicates that the SCTP association is congested. The primary cause of the alarm is that the network is congested. To correct the primary cause of the alarm, eliminate the network congestion caused by routing or switching issues. The secondary cause of the alarm is that the CPU is throttled. To correct the secondary cause of the alarm, upgrade to a more powerful platform or offload some traffic.

Subscriber Line Faulty—Signaling (151)

The Subscriber Line Faulty alarm (minor) indicates that the residential gateway returned an error code in response to a command from the MGW. To correct the primary cause of the alarm, try controlling subscriber termination to OOS and back into INS using the Cisco BTS 10200 CLI command. If the problem persist after more calls, check the configuration in the Cisco BTS 10200 and the RGW. If the error codes returned by MGW are harmless, the error codes can be suppressed by adding a new entry in the MGCP-RETCODE-ACTION table and changing the EP-ACTION to reset/none.

Note The following additional troubleshooting information is applicable to Release 5.0 MR2 and above.

If the VXSM is OOS at the GW side, a 501 error message for CRCX/AUEP may be transmitted. This generally occurs if there is resource state mismatch between the Cisco BTS 10200 (ACTV IDLE) and the VXSM (DOWN). For additional information on the 501 error message, refer to Appendix A, "Recoverable and Nonrecoverable Error Codes."

When the mismatch occurs the default behavior is update for both the create connection (CRCX) and audit endpoint (AUEP) messages. For example:

CLI> add mgcp-retcode-action mgw-profile-id=<abc>; mgcp-msg=AUEP; mgcp-retcode=501; 
call-action=release; ep-action=update

CLI> add mgcp-retcode-action mgw-profile-id=<abc>; mgcp-msg=AUEP; mgcp-retcode=501; 
call-action=release; ep-action=update

If a 501 response is received for the CRCX message on execution of the EP-ACTION=update for CRCX, the Cisco BTS 10200 will start auditing the endpoint by sending an AuditEndpoint message requesting restart-method (rm parameter reported in the RSIP message, which indicates the service state at the GW). If the restart-method information reported in AUEP message is different from the Cisco BTS 10200 termination state, the termination state will be updated accordingly. If rm=forced, the termination oper-status is set to down; if rm=restart, the termination oper-status is set to up.

If a 501 response is received for the AUEP message on execution of the EP-ACTION=update for AUEP, the Cisco BTS 10200 will unconditionally mark the termination as down.

To clear down from the termination oper-status, you either need to control the trunk/subscriber-termination OOS/INS mode=forced; or trigger RSIP rm=restart from the GW.

Emergency Trunks Become Locally Blocked—Signaling (153)

The Emergency Trunks Become Locally Blocked alarm (critical) is issued when an emergency trunk (CAS, SS7, or ISDN) becomes locally blocked.

Emergency Trunks Become Remotely Blocked—Signaling (154)

The Emergency Trunks Become Remotely Blocked alarm (critical) is issued when an emergency trunk (CAS, SS7, or ISDN) becomes remotely blocked.

Integrated Services Digital Network Signaling Gateway Down—Signaling (156)

The Integrated Services Digital Network Signaling Gateway Down alarm (major) is issued when the Cisco BTS 10200 cannot communicate to the ISDN gateway. The primary cause of the alarm is that the Cisco BTS 10200 cannot communicate to the ISDN gateway due to a failure in the gateway. Additionally, the SCTP association might be down. To correct the primary cause of the alarm, find out whether the SCTP association is down and restore the SCTP association. The secondary cause of the alarm is that the IUA layer may be down in the gateway. If the IUA layer is down, it will be automatically recovered; no further action is required.

Integrated Services Digital Network Signaling Gateway Inactive—Signaling (157)

Session Initiation Protocol Server Group Element Operationally Out of Service—Signaling (162)

The Session Initiation Protocol Server Group Element Operationally Out of Service alarm (critical) is issued when the Cisco BTS 10200 is unable to communicate with a remote SIP party. The primary cause of the alarm is that the Cisco BTS 10200 is unable to communicate with a remote SIP party (call-agent or proxy) over a SIP server group element. To correct the primary cause of the alarm, verify DNS resolution exists if TSAP address of the remote entity is a domain name. Verify the remote entity is reachable by ICMP ping, using the TSAP address from the Event Report. If the same alarm is reported for other TSAP addresses on several softswitch trunk groups and/or server-group elements, then verify that the network connection is operational. The secondary cause of the alarm is that the remote SIP party is not operational. To correct the secondary cause of the alarm, diagnose the issue that prevents the TSAP address from being reached if a ping is not successful. Verify that the SIP application is running on the remote host and listening on the port specified in the TSAP address.

Routing Key Inactive—Signaling (163)

The Routing Key Inactive alarm (major) indicates that inactive acknowledgement messages were received from a Signaling Gateway. The SG or SCTP associations are probably down. To troubleshoot and correct the primary cause of the Routing Key Inactive alarm, investigate other alarms to see if SGs are down or the SCTP associations are down. Take corrective action according to those alarms. Also check the AS status for the routing context on ITP.

Signaling Gateway Traffic Mode Mismatch—Signaling (164)

The Signaling Gateway Traffic Mode Mismatch alarm (major) indicates that the traffic mode does not match on the Cisco BTS 10200 and the Signaling Gateway. To troubleshoot and correct the primary cause of the Signaling Gateway Traffic Mode Mismatch alarm, verify the AS traffic-mode configuration in the Signaling Gateway. Check that the SG internal redundancy mode for the traffic-mode setting has been set correctly in the Cisco BTS 10200.

Residential Gateway Endpoints Are Out of Service at the Gateway—Signaling (170)

The Residential Gateway Endpoints Are Out of Service at the Gateway alarm (minor) indicates that the residential gateway has been administratively taken OOS using the command at the gateway. To troubleshoot and correct the primary cause of the Residential Gateway Endpoints are out of Service at the Gateway alarm, bring the residential gateway administratively into INS using the command at the gateway.

Residential Gateway Unreachable—Signaling (171)

The Residential Gateway Unreachable alarm (minor) indicates that a MGCP signaling interop error has occurred with the residential media gateway. To troubleshoot and correct the primary cause of the Residential Gateway Unreachable alarm, check the IP connectivity status between the Cisco BTS 10200 call agent and the trunking gateway if the residential gateway is not physically connected, but controlled INS at the Cisco BTS 10200.

Multimedia Terminal Adapter Effective-Aggr-Id Becomes Unavailable Due to Its IP Address—Signaling (172)

The Multimedia Terminal Adapter Effective-Aggr-Id Becomes Unavailable Due to Its IP Address alarm (major) indicates that the MTA has been moved to new subnet which is not provisioned, or provisioned with the aggr-id=null. To troubleshoot and correct the primary cause of the Multimedia Terminal Adapter Effective-Aggr-Id Becomes Unavailable Due to Its IP Address alarm, provision the subnet aggr-id for the MTA.

ENUM Server Domain Cannot be Resolved Into Any IP Address —Signaling (173)

The ENUM Server Domain Cannot be Resolved Into Any IP Address alarm (critical) indicates that a misconfiguration has occurred in the DNS configuration. To troubleshoot and correct the cause of the alarm, fix the DNS configuration according the documentation.
