6.4.6 Managing Node Clocking
On Cisco MGX 8850 (PXM1E) switches, clock source configuration is done on the PXM1E card and passed to other nodes over PXM1E lines.
On Cisco MGX 8850 (PXM45) switches, clock source configuration is done on a PXM45 card, and clock sourcing information is passed to other nodes over AXSM lines.
Cisco MGM supports the manual clock configuration method of network clock synchronization for the Cisco MGX switches. Manual clock configuration configures both a primary and secondary clock source, which are distributed throughout the network. The secondary clock source takes over if the primary clock source fails. You can configure a network setup with one master clock source, and a secondary to ensure network clock stability.
You can manage three types of node clocking:
•Configuring Global Clocking
•Viewing Available Clock Sources
•Viewing or Creating Manual Clock Sources
6.4.6.1 Configuring Global Clocking

6.5 How Do I Create or Modify APS?
Automatic Protection Switching (APS) can be configured on SONET lines within SRME or AXSM and VXSM OC-type cards.
If you are setting up APS on multiple cards, you must first set up an APS connector and then set up redundancy on the node (for details on setting up redundancy, see Configuring Card Redundancy.)
Step 1 From the Domain Explorer window, select the node from the Hierarchy pane and choose Configuration > MGX 8880/8850 MG > Configuration Center. The Configuration window for the selected node opens.
Step 2 Double-click an AXSM, SRME or VXSM card.

6.7 How Do I Configure VXSM Cards?
Tip For more detailed information on VXSM configuration, refer to the Cisco Voice Switch Services (VXSM) Configuration Guide and Command Reference for MGX Switches and Media Gateways, Release 5.
The Cisco MGX 8880 and 8850 support the Voice Switch Service Module (VXSM) card, which functions as a media gateway (MG) and can be configured to meet the requirements of a variety of applications. For Voice over IP (VoIP) switching applications, the voice Time Division Multiplexed (TDM) interface, packet network interface, and the interface to the media gateway controller (MGC or call agent must be configured.

6.7.6 Configuring MG-MGC Interfaces
VXSM cards support both the ITU H.248 and the XGCP protocols. Depending upon which protocol you are using, the procedure to configure the MG-MGC interface differs.
For each protocol type, the procedure consists of two phases. The first phase configures MGC and MGC Groups. The second phase configures the protocol and protocol profile details that are used for the VXSM and the MGC to communicate.
Figure 6-35 Process for Configuring MG-MGC Interfaces
Before you can configure MG-MGC interfaces, be sure you have completed the following steps:
Step 1 Add a resource partition to the node—See Creating a Resource Partition for VXSM.
Step 2 Add an AAL5+control VXSM connection—See "Provisioning Connections."
Step 3 Create and assign an IP address for the connection—See Creating and Assigning an IP Address for the Connection.
To configure the interface between the Media Gateway (MG) and the Media Gateway Controller (MGC) for either protocol, complete the following steps:
Step 1 Setup MGC and MGC groups—See Setting Up MGCs and MGC Groups.
Step 2 Configure H.248 or XGCP protocol— See Configuring H.248 Protocol and Profiles or Configuring XGCP Protocol.
Step 3 Configure the MGC profile—See Configuring H.248 Protocol and Profiles or Configuring MGC XGCP Profiles.

6.7.7.4 Configuring Announcements
In switching mode, VXSM delivers prerecorded announcements in either direction, for example, a calling party or called party, under the control of the MGC. These announcements are played during a call setup and after the call is established. The announcement files are available in VXSM memory to be played out. If the file does not reside in VXSM memory, VXSM uses TFTP to obtain the file from an external announcement server, caches it, and plays it out.
A media gateway is a network element. It provides an electrical conversion between audio signals carried on telephone circuits and data packets carried over the Internet or over other packet data networks. To setup an announcement system, the media gateway plays prerecorded audio files. These files are played bidirectionally over existing connections, for example, calls, or the audio files are directed toward a TDM network to a TDM endpoint that is terminated on a media gateway.
To configure the announcement control parameters:
Step 1 From the Domain Explorer window, choose Configuration > MGX 8880/8850 MG > Configuration Center.
Step 2 Under the Elements tab, within the node, double-click the VXSM card.
Step 3 Click the VOICE Features tab.
Step 4 Choose the Announcement Controls option from the Category drop-down arrow.

Domain Name Resolution |
Specifies the domain name resolution for the domain name of the announcement file server which is specified by the Audio File Name object. If this object is set to internalOnly, the IP address associated with the file server (Audio File Name) will be determined by the cannoIpAddress object. Values include: •internalOnly (default)—Specifies the internal resolution of the domain name for the announcement file server. If the internalOnly option is chosen, the IP address associated with the file server is determined according to the IP address of the server. •externalOnly—Specifies the external resolution of the domain name for the announcement file server. |
Server IP Address Type |

Play Duration (10 milliseconds) |
Duration that the announcement file is played during an announcement cycle. The range is from 0-65535 ms. The default value is zero. The value zero indicates that the duration of the announcement is a variable, and the Number of Cycles parameter determines the time. Note The Play Duration (10 milliseconds) field is applicable only for playing a fixed announcement.
To play a fixed announcement, the Number of Cycles parameter and the Play Duration parameter are used together to determine how long the announcement is played. |

Admin State Control |
This control object is used to change the service state of the line from is to coos or from coos to is. The resulting service state of the line is represented by vismDsx1State. inService: transition vismDsx1State to is. In the course, the MGs MGCs may get notified of this transition, e.g. in the case of MGCP through emission of RSIPs to registered call agents according to policy. forcefulOutOfService: Take the line out of service forcefully. This releases any resources at the line. In the course, the MGCs may get notified of this transition, e.g in the case of MGCP through emission of RSIPs to registered call agents according to policy. gracefulOutOfService: Take the line out of service gracefully. If there are no resources existing, vismDsx1State transitions to coos immediately. If resources exist, vismDsx1State transitions to poos thus initiating a graceful shutdown. In the course, the MGs MGCs may get notified of this transition, e.g. in the case of MGCP through emission of RSIPs to registered call agents according to policy. |
