Adding System Components with MML
This chapter describes how to add system components, describes how to verify the addition of the components, and gives tips that can help you solve problems. It provides information about:
•Adding SS7 Signaling Route Components
•Adding Signaling Link Components
•Adding Trunks, Trunk Groups, and Routing
Before starting an actual configuration, refer to "Planning for Provisioning" for instructions and worksheets for configuring your system. That chapter describes the system components that need to be configured on the MGC. Each component has a specified type, name, and description, and may have additional configuration parameters.
When adding components, add the components in the following order.
•External nodes
•Point codes (OPC, APC, and DPC)
•Adapter cards
•Adapter interfaces
•Signaling services
•Linksets
•Links
•SS7 routes
•SS7 subsystems
•Trunk groups
•Trunks
•Route groups
Adding SS7 Signaling Route Components
Your first task is to configure SS7 signaling routes that link the MGC to the SS7 network nodes (signaling points). You typically do this by:
•Adding an Adjacent Point Code
•Adding an SS7 Signaling Service
•Adding a TCAP over IP Signaling Service
•Adding a FAS Signaling Service
Note When provisioning, fully define all components (see Figure 2-2) before deploying a configuration.
To add a system component, do the following:
Step 1 Start MML as described in the "Working with MML" section.
Step 2 Start a provisioning session as described in the "Starting a Provisioning Session" section. The source configuration that you chose during startup determines the configuration to which you can add components.
Step 3 Enter the following command:
prov-add:componentType:name="name", desc="description", paramName=valueReplace the componentType parameter with the type of component you want to create. To define more than one parameter, enter the additional paramName=value descriptions on the command line.
Provide a description. The description can be as many as 128 alphanumeric characters in length.
Replace the name parameter with the name you want to give to the component. The name can be as many as 20 characters in length and can only be number and letter symbols, and the dash (-) symbol.
SS7 System Component Hierarchy
When you are adding SS7 system components, create them in proper order. For example, before you add a point code, you must define the external nodes.
Adding a Point Code
A point code is an SS7 network address that identifies an SS7 network node, such as a switch, SCP, STP, or SSP. Its MML name is PTCODE. This can be the MGC's originating point code (OPC) or the destination point code (DPC) of a remote node with which the MGC communicates.
Note For information on point code parameters, refer to Table 2-1.
Procedure
To add a point code to the MGC configuration, use the PROV-ADD command.
Verify
Use the PROV-RTRV command to verify.
Tip Point codes provide the addressing scheme for the SS7 network. ITU point codes are 14 bits long, and ANSI point codes are 24 bits long.
Adding Multiple OPCs
Depending on your system configuration, you may have to assign more than one OPC to a single MGC. When adding multiple OPCs, keep the following information in mind.
•ITU point codes contain 14 bits and ANSI point codes contain 24 bits.
Note Use care when supplying ITU point codes since they are not checked in the provisioning session.
•A maximum of 6 true OPCs can be supported per MGC.
•For each OPC added, you must specify a different local port number for each C7 IP link on the same interface.
•For each OPC added, you must create a duplicate DPC with a different name but with the same
IP address.•Each OPC must have a unique network address.
•Enter the OPC before creating the C7 IP link.
•When specifying a local port number, it must be greater than 1024 (for example, 7000).
•Each OPC requires its own linkset (a linkset cannot be shared by 2 OPCs).
•A maximum of 2 Session Manager sessions (1 active and 1 standby) can be supported per SLT (1 session per link).
•A maximum of 32 links can be supported per Control Channel.
•A maximum of 16 linksets can be included per Control Channel.
•A maximum of 4,096 DS0s (CICs) can be supported per OPC-DPC pair for ITU or a maximum of 16,384 DS0s (CICs) for ANSI.
Procedure
To add another point code to the MGC configuration, use the PROV-ADD command.
Due to the number of commands involved to add an additional OPC, the commands have been included in the following series of commands.

Use the PROV-RTRV command to verify.
Tip Setting up linksets is a two-step process that consists of first adding the linkset and then adding links to the linkset.
Adding an SS7 Subsystem
The SS7 subsystem is a logical entity that mates two STPs. When two STPs are defined as mates within the MGC, the controller can use either STP for communications to a destination device. The SS7 subsystem MML name is SS7SUBSYS.
For information on SS7 subsystem parameters, refer to Table 2-5.
Procedure
Verify
Use the PROV-RTRV command to verify.
Tip Protocol families must be the same for mated subsystems. If one pair of STPs handles both ITU and ANSI variants, you must configure two pairs of STPs: one for ITU and the other for ANSI.
Adding Subsystem Numbers
You can also use the SS7 subsystem to define an SCP using TCAP. For TCAP applications, TRANSPROTO is set to TCPIP, and the subsystem number is set to a value greater than 0 to support AIN. You also must set STPSCPIND to route to the appropriate SCP. For information on SS7 subsystem parameters including STPSCPIND, refer to Table 2-5.

Tip When defining a new ITU service for SCCP/TCAP, you must first enter a "dummy" DPC. This DPC is not used for routing calls, but is used internally by the software.
To define a dummy DPC, refer to the "Adding a Point Code" section and add a DPC with the following parameters:
•MML name: itudummy
•Description: Dummy Point Code for ITU service
•Network address: 9.9.9
•Network Indicator: National network
You also select this dummy DPC when you are provisioning the SS7 route for the ITU service. Refer to the "Adding an SS7 Route" section.
Adding a FAS Signaling Service
This is the facility associated signaling (FAS) service or signaling path to a particular destination when you are using either ISDN-PRI or DPNSS. Its MML name is FASPATH.

Use the PROV-RTRV command to verify.
Tip You must configure the adapter/card before configuring the interface.
Adding a C7 IP Link
A C7 IP link component identifies a link between a Cisco SLT IP address and port and the SS7 network (SSP or STP). Its MML name is C7IPLNK.
Tip For SS7 provisioning, keep the following points in mind.
A maximum of 6 OPCs that can be supported.
Enter routing information fo rthe OPC before creating the C7 IP link.
For each OPC added, you must specify a different local port or each C7 IP link.
Provision a maximum of 32 links per local port number. Specify another port number for each additional group of 32 links.
For information on C7 IP link parameters, refer to Table 2-14.
Procedure

A TDM link is a communications link between a TDM interface card on the MGC and a TDM hardware element. For each link, you need to specify the card interface to which the link connects. Its MML name is TDMLNK.
For information on TDM link parameters, refer to Table 2-15.
Procedure
Verify
Use the PROV-RTRV command to verify.
Adding MGW Control Links
Now you need to configure MGW control links. The MGC uses these links to control the bearer traffic that passes between each MGW. You typically add MGW control links by:
•Adding an EISUP Signaling Service
•Adding an SGCP Signaling Service
•Adding an IPFAS Transport Service
•Adding and Modifying an MGCP Signaling Service Property
•Adding a NAS Signaling Service
Adding an External Node
An external node is an MGW with which the MGC communicates. Its MML name is EXTNODE.
For information on external node parameters, refer to Table 2-16.
Procedure
Verify
Use the PROV-RTRV command to verify.
Tip You must create an external node for each media gateway.
Adding a Card
The card being referred to is a network card or adapter that is operating in the MGC. Its MML name is CARD.
Adding an Ethernet Interface
The Ethernet interface provides the physical line interface between an MGC Ethernet network card/adapter and the physical Ethernet network. You configure parameters that control communications between the network card/adapter and the Ethernet. Its MML name is ENETIF.
Each SS7 link in the node must be associated with an Ethernet interface component, which must be associated with a network card. The Ethernet interface represents a physical network connection on the network card.
Note In the MGC, the same cards and interfaces can be used for communication with Cisco SLTs and media gateways. When configured this way, separate links are assigned for Cisco SLT and media gateway communications.
Adding an EISUP Signaling Service
The EISUP signaling service or signaling path is the signaling path to an externally located MGC (destination). Its MML name is EISUPPATH.
For information on signaling service parameters, refer to Table 2-17.

Adding a NAS Signaling Service
The NAS signaling service is the Q.931 protocol path or NAS signaling service between the MGC and the MGW. Its MML name is NASPATH.
Note If you are configuring a redundant system, you must define two redundant link manager links between each MGC and MGW. Each redundant link manager group must be associated with a different port number and a different NASPATH, but the same EXTNODE.
For information on signaling service parameters, refer to Table 2-17.
Procedure
Verify
Use the PROV-RTRV command to verify.
Tip For the NASPATH component, there is only one protocol: Bell_1268_C3.
Adding an IP Link
The IP link is an IP connection between an MGC Ethernet interface and an MGW. Its MML name is IPLNK.
For information on IP link parameters, refer to Table 2-21.
Procedure
Verify
Use the PROV-RTRV command to verify.
Tip When configuring two IP links to the same NAS, you need to configure two different Ethernet IP addresses on both the MGC and the NAS.
Adding an IP Link Requiring a Subnet Address (Release 7.4(10)
The IP link is an IP connection between an MGC Ethernet interface and an MGW. Its MML name is IPLNK. When the IP link is to another subnet, the optional NEXTHOP and NETMASK parameters are recommended.
For information on IP link parameters, refer to Table 2-21.
Procedure
Verify
Use the PROV-RTRV command to verify.
Tip When configuring two IP links to the same NAS, you need to configure two different Ethernet IP addresses on both the MGC and the NAS.
All IP links and C7 IP links with a PEERADDR on the same network must have the same NEXTHOP.
For each IP link and C7 IP link, the NEXTHOP must be on the same network address as the IPADDR.
When NEXTHOP is set to 0.0.0.0, the IP routing feature is disabled.
A value of 0.0.0.0 for the NETMASK is not allowed.
As a binary number, the NETMASK cannot have any 1 bits less significant than the most significant 0 bits. For example, a NETMASK of 0.0.255.255 is invalid.
Adding Multiple FAS Signaling Services and IP Links
To configure the D channels on a Cisco MGX8260, you have to provision one IPFAS path and two IP links for each D channel. The MML component for provisioning multiple IPFAS paths and associated IP links on the Cisco MGX8260 is MLTIPFAS.

Component: mlttrnkgrp
Name: 1000
NUMTRNKGRP: 2
Verify
Use the PROV-RTRV command to verify.
Scaling System Components
After you have configured your system components, you can begins scaling your system. Keep the following in mind when scaling.
Tip A maximum of 6 OPCs can be supported per MGC.
Enter routing information for the OPC before creating the C7 IP link.
For each OPC added, you must specify a different local port for each C7 IP link.
Provision a maximum of 32 links per local port number. Specify another port number for each additional group of 32 links. As many as 192 links can be supported per MGC.
Planning for future network expansion by spreading the linksets evenly across the Control Channels is suggested. Failure to do so will require the linksets to be removed from service to add more links.
As many as 256 NASs can be supported. When creating IP links to the NASs, increment the MGC port number after 32 links have been added. Be sure to set the NAS RLM to match the MGC RLM port value.
Dynamically Configuring the Input/Output Channel Controller
When dynamically configuring the IOCC, evenly distribute number of channels associated with one channel controller. For different signaling service, there are different rules when associating channels with channel controllers. The number of links associated with a channel controller is configurable on a protocol family basis through parameters contained in XECfgParm.dat. If the number of links exceeds the limit defined in XECfgParm.dat, a new instance of channel controller is created.
The naming convention for creating a new channel controller is the first five characters of the protocol family, plus a dash (-), and <num>, where num is number of channel controllers per protocol family created so far.
