TCM Overview
This chapter describes how to provision the MGC using the Telephony Controller Manager (TCM).
Note The name TCM refers to an earlier product name of the media gateway controller (telephony controller). You use the TCM to provision your MGC.
The TCM is an X-windows graphical user interface (GUI) that accesses MGC information using Simple Network Management Protocol (SNMP). You can use the TCM to perform the following tasks:
•Setting up your initial system configuration
•Adding or deleting system components (for example, point codes, gateways, switches, and other nodes)
•Setting up links and signaling services between components
•Provisioning component properties
•Setting up number analysis and routing
•Saving or changing subsequent provisioning sessions
The TCM can be used alone or with MML commands to provision your system. For more information on using MML, refer to "Configuring with MML."
Information to Gather
You should have the information contained in "Provisioning Overview," before beginning your provisioning session.
TCM Provisioning Overview
The TCM provides a GUI that allows you to create provisioning sessions. The TCM saves your current provisioning session each time you click a set command. After you finish the provisioning session and choose commit or deploy, the TCM saves your configuration as the active configuration. After you have created the active configuration, you cannot modify it. To make changes, you must save it with another name and commit or deploy the new provisioning session to make it active.
The software allows only one active provisioning session. Therefore, you cannot have an active MML provisioning session open at the same time you are using the TCM. Other users can access the TCM, but will remain in read-only mode, and the create, modify, set, and delete buttons are not enabled.
Read-only mode permits viewing of the current active provisioning data; this data is stored in the /opt/TransPath/etc directory on the Cisco media gateway controller (MGC) host. Read-only users cannot access any other provisioning sessions, regardless of what is entered in the Source Version Name or Destination Version Name fields. In a read-only mode, information in the view, traffic and number analysis tabs can be edited and used to create files on the local machine. You can also export customer-specific files when in read-only mode.
Note Only one active TCM provisioning session is permitted to run on the same host machine; read-only is not permitted. You must use a different host machine to gain read-only access if another user is provisioning on the same host machine.
The number of configurations you can store might be limited by available disk space. Consider deleting old or unwanted configurations, or saving them to another machine if you do not have sufficient disk space.
Note For properties not described in this chapter, refer to the Cisco Media Gateway Controller Software Release 7 Reference Guide.
Note On the Cisco MGC running software Release 7.3(15)C, the standby system might not recover from a failover if the active system has an open provisioning session. Make sure that there is no provisioning session open on the active MGC.
Starting the TCM
To start the TCM:
Step 1 Log in as a member of the transpath group. Refer to Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide for more information on setting up user privileges and access rights.
Note You must be logged in to the TCM server or access it from a machine with X-windows capability.
Step 2 In the terminal window, enter:
cd /opt/VSCprov/bin
./start.sh
The system opens the X-windows interface and the login screen, shown in Figure 3-1, appears.
Figure 3-1 Login Screen
Note The terminal window in which you originally started the TCM remains open, and due to software limitations, extraneous error messages can appear.
Timesaver The system automatically enters the values in the login screen if you type the IP Address/Host Name, Source Version Name, and Destination Version Name after the ./start.sh command at the prompt in Step 2. For example, enter:
cd /opt/VSCprov/bin
./start.sh IPAddr/HostName SourceVersionName DestVersionName
Step 3 In the IP Address/Host Name field, enter the host name or the IP address of the Cisco MGC host. Typically, the Cisco MGC software resides on a machine different from the TCM provisioning tool but, it can reside on the same host.
Step 4 In the Read Community Name and Write Community Name fields, accept the default (Public).
Step 5 In the Source Version Name field, enter one of the following:
•new—Creates a new configuration. When you are creating a new configuration, the Cisco MGC software does not allow you to overwrite an existing configuration. If the destination directory you specify already exists, you receive an error message.
•active—Retrieves the active configuration for changing. You must enter a new destination version name.
•SourceVersionName—If you enter the name of a previous inactive configuration, the system uses that configuration as a basis for a new configuration. The name can be as many as 15 alphanumeric characters and must start with a letter or number.
Step 6 In the Destination Version Name field, enter the name of a new version you want to create. The name can be as many as 15 alphanumeric characters, hyphens, or underscores. You cannot use "active" or "new."
Caution
Do not name the destination directory "active." The name "active" has a special meaning in the Cisco MGC software. If you use this name as the destination directory, you will not be able to access the configuration in later provisioning sessions.
Note To modify an existing inactive provisioning session, use the same provisioning session name for both the source version name and the destination version name.
Step 7 Press Connect to start the provisioning session. The main window (see Figure 3-2) appears.
Note If you are working on a small screen, all of the buttons may not be visible on your screen. Adjust the screen resolution or the font size until you can see all the buttons.
Figure 3-2 Main Window
Tip Depending on the X-windows software you are using when entering data in the TCM, you might need to press Shift when using the Backspace key.
Navigating the TCM
Tabs
The TCM provides tabs to navigate through the system. You click on these tabs to add or change network components. The TCM contains the following tabs:
•Telephony controller tab—Used to add components and provision component properties.
•Traffic tab—Used to create customer-specific files, including trunk groups, trunks, and routing.

The components are listed and defined in "Planning for Provisioning."
Components are structured hierarchically, although the structure that appears on the TCM screen does not reflect their true hierarchy. You must provision parent components (for example, the point code component) before provisioning children components (for example, the linkset). Figure 3-6 shows the component relationship.
Note These components vary depending on which solution you are implementing. You will not use all components in a single configuration.
Figure 3-6 TCM Component Relationships
Entering MML Names and Descriptions
You must enter an MML name and a description for each component you provision. MML names must have the following characteristics:
•As many as 10 alphanumeric characters, including hyphens
•No space, underscore, decimal, or special characters
•Must start with an alphabetic character
•Must be lowercase
Descriptions can be as many as 128 characters and can include spaces and symbols. You should use descriptions that help identify the components or links that you are provisioning. For example, for an SS7 route, which indicates the signaling path from the Cisco MGC to a switch through a linkset, you could create a description SS7 Route to PSTN Switch A through Linkset 1.

Adding TDM Links
You must add a TDM link for each path from the TDM to the Cisco MGC. You have one link for each T1/E1 card in the Cisco MGC host, which is associated with a TDM interface. These links are contained within the linksets you previously created. (Refer to the "Adding Linksets" section.) To add TDM links, perform the following steps:
Step 1 Click TDMLink to display the TDM Link menu, see Figure 3-24.
Step 2 Click Linkset and choose the linkset for this link.
Step 3 Enter the MML name.
Step 4 Enter the description.
Step 5 Enter the link code.
Step 6 Choose the priority. Value range: 1 through 4. 1 is the highest priority.
Step 7 Click TDM Line Interface to choose the TDM interface for this link.
Step 8 Enter time slot number in the time slot field. This is the channel on the physical line from the TDM to the Cisco MGC. Value range: 1 through 32.
Step 9 Click Create. A set successful message appears.
Step 10 Click OK.

Adding SS7 Routes
You must add an SS7 route for each signaling path from the Cisco MGC to the PSTN switch through the linksets you have created to the STPs. You should create two routes to the PSTN switch, with each route passing through a different STP of a mated pair. For more information about SS7 routes, refer to the "Defining SS7 Routes" section. To add an SS7 route, perform the following steps:
Step 1 Click SS7Route to display the SS7 Route menu, see Figure 3-25.
Step 2 Enter the MML name.
Step 3 Enter the description.
Step 4 Click Signal Destination or Adjacent Point Code and choose the DPC of the PSTN switch, or the APC if the APC is the destination of the path.
Step 5 Click Link Set to choose the linkset for this route.
Step 6 Click Originating Point Code to choose the originating point code for this route.
Step 7 Choose priority. Value range: 1 through 4. 1 is the highest priority.
Step 8 Click Create. A set successful message appears.
Step 9 Click OK.
Figure 3-25 Adding an SS7 Route
Adding an SS7 Subsystem
SS7 subsystems are used by the MGC software to identify a pair of mated STPs. The SS7 subsystem allows the Cisco MGC to route traffic over the C-links between the STPs in case of a failure between one of the STPs and an endpoint. The links to these STPs were defined in the "Adding Linksets" section.
Note The SS7 subsystem is also used to provision TCAP queries to an SCP database for AIN services. This functionality is available in release 7.4(x) of the Cisco MGC software. For more information, refer to "CMM Provisioning Procedures for Release 7.4(x)."
For more information about an SS7 subsystem, refer to the "Defining SS7 Subsystems" section. To add an SS7 subsystem, perform the following steps:
Step 1 Click SS7SubSys to display the SS7 Sub System menu, see Figure 3-26.
Step 2 Enter the MML name.
Step 3 Enter the description.
Step 4 If identifying mated STPs, click Adjacent Point Code to choose the APC of the first STP.
Step 5 If identifying mated STPs, click Mated Adjacent Point Code to choose the APC of the second STP. If using the subsystem for AIN queries, choose None.
Step 6 Choose Protocol Family:
•SS7-ANSI—Use when identifying mated STPs or using the subsystem for AIN queries.
•SS7-China—Use when identifying mated STPs only.
•SS7-ITU—Use when identifying mated STPs or using the subsystem for AIN queries.
•SS7-Japan—Use when identifying mated STPs only.
•SS7-UK—Use when identifying mated STPs only.
Note If you have multiple linksets to an STP that use different protocol families, you must also have multiple SS7 subsystems—one for each linkset that uses a certain protocol.
Step 7 Choose the priority. Value range: 1 through 4. 1 is the highest priority.
Tip When you are identifying mated STPs, the priority for the SS7 subsystem should always be lower than the priority for the C7 IP links between the Cisco MGC and the STPs (which you provisioned in the "Adding C7 IP Links" section). You do not want signaling traffic on the C-links between the STPs; these are used only if links go down. If the priority for the C-links (SS7 subsystem) between the STPs is higher than or equal to the priority for the C7 IP links, the Cisco MGC routes signaling traffic over those links. If you set the SS7 subsystem priority lower than priority for the C7 IP links, the Cisco MGC routes traffic over the C-links between the STPs only if the links with a higher priority are not available.
Step 8 Enter 0 for the Sub System Number (SSN).
Step 9 Enter 0 in the STP-SCP index field. When identifying mated STPs, enter 0.
Step 10 Choose the SCCP transport protocol.
Note Not used when identifying mated STPs.
Step 11 Click Create. A set successful message appears.
Step 12 Click OK.

Modifying System Components
To modify components, select the component in the left side of the screen. On the right side of the screen, modify the desired fields and click Modify. The system returns a set successful message.
Note You cannot modify some fields in a component that are used by other components in the system. For example, you cannot change a card type, because the card type field is used in the interface component. Fields that you cannot modify appear gray, and you cannot enter information in them.
Tip You cannot modify MML names once you have created a component. You must delete the component and enter a new component with a different name.
Deleting System Components
To delete components, select the component and click Delete in the right screen panel. A dialog box asks you to confirm any deletions.
Note You cannot delete a component that is a parent of another component. For example, you cannot delete a linkset that contains links. You receive an error message when you try to delete a parent component. See Figure 3-6 for the hierarchy of TCM components.
Adding Trunks
You must add trunks for each connection between the media gateway and a destination switch. For the Cisco SS7 Dial Access Solution and the Cisco H.323 VoIP with SS7 Connectivity Solution, these trunks are nailed. With nailed trunks, the Cisco MGC does not perform switching of trunks.
Creating the Trunk File
To add trunks using the Traffic tab in the TCM, first create the trunk file that will be populated with your data, perform the following steps:
Step 1 Click the Traffic tab.
Step 2 Click Trunks. The Create Trunks File Name window appears.
Step 3 Click Trunk Type and choose Nailed.
Step 4 Enter the filename and click Create New File. A set successful message appears.
Step 5 Click OK.
Note You can name the trunk file with any extension except .old (reserved for use by the TCM software). In this documentation, .txt is used.
After you set the filename, the filename and BCFile components appear under the Trunks component in the left screen panel. Click the + sign next to the filename to display the Nailed or Switched component.
Adding Nailed Trunks
To add the individual nailed trunks, perform the following steps:
Step 1 Under the trunk filename component you created, click Nailed. The Nailed Bearer list appears and is empty.
Step 2 Click New.
Step 3 Enter the trunk ID.
Step 4 Click Source Signaling Service and select the appropriate SS7 signaling service.
Step 5 Select Fixed for the Source Span.
Step 6 Enter ffff for the Source Span ID.
Step 7 Enter the Source Time Slot/CIC. This identifies the time slot on the T1 at the destination (PSTN switch).
Step 8 Click Destination Signaling Service and choose the gateway signaling service.
Step 9 Select Fixed for the Destination Span. (This is the destination span type.)
Step 10 Enter the Destination Span ID. This value identifies the appropriate T1 or E1 line and T1 or E1 controller on the gateway. For example, it is the nfas_int value that is set in IOS on the NAS.
Step 11 Enter the Destination Time Slot/CIC field. This identifies the time slot on the T1 that terminates at the gateway.
Step 12 Select the line type:
•T1
•E1
Step 13 Enter the number of trunks in the multiple trunks field. For T1, you can enter 1 through 24. For E1, you can enter 1 through 31. The system automatically increments the trunk ID, source time slot/CIC, and the destination time slot/CIC.
Step 14 Click Set. A set successful message appears.
Step 15 Click OK.
Processing the Trunk File
After you add the trunks, you must process the trunk file. To process the file, perform the following steps:
Step 1 Under the trunk filename, select the BCFile component.
Step 2 Enter the filename.
Step 3 Enter your user ID and password. Only this user is allowed to modify the file.
Step 4 Click Set. A set successful message appears.
Step 5 Click OK.
The system opens a File Transfer Protocol (FTP) session to the Cisco MGC host and copies the file. In addition, Simple Network Management Protocol (SNMP) sets the filename in the Management Information Base (MIB), and the file is post-processed.
Note Only one filename can be set in the MIB. If a new filename is set using SNMP, the old name is overwritten.
Tip If you receive an error message that the file cannot be processed, your SNMP session might not be running. The SNMP session times out after 30 minutes of inactivity. Exit the TCM and restart it before trying to process the file.
Modifying Trunks
To modify trunks, in the left side of the screen, select the name of the trunk filename you created in the "Creating the Trunk File" section. The right side of the screen displays the Nailed Bearer List or the Switched Bearer List.
To modify a trunk, perform the following steps:
Step 1 Select the trunk from the list and click Modify. The system prompts you with a window showing the changes you are requesting and asks you to confirm the modification.
Step 2 Click Yes to modify the trunk. A set successful message appears.
Step 3 Click OK.
Deleting Trunks
To delete trunks, in the left side of the screen, select the name of the trunk filename you created in the "Creating the Trunk File" section. The right side of the screen displays the Nailed Bearer List.
To delete a trunk, perform the following steps:
Step 1 Select the trunk from the list and click Delete. A dialog box displays the line you want to delete and asks you to confirm the deletion.
Step 2 Click Yes to delete the trunk.
Step 3 A dialog box displays the number of the trunk you deleted. Click OK.
Retrieving Trunk Files
Although the TCM allows you to use only one trunk file at a time, you can retrieve trunk files you previously created. To retrieve trunk files, perform the following steps:
Step 1 Click the Trunks component.
Step 2 In the lower half of the window, enter the filename of the file you want to retrieve.
Step 3 Enter the user name and password you gave the file when you created it.
Step 4 Click Get Existing. A set successful message appears.
Step 5 Click OK.
Trunk Groups and Trunk Routing
Trunk groups and trunk routing are not used in the Cisco SS7 Dial Access Solution or the Cisco H.323 VoIP with SS7 Connectivity Solution. These solutions used nailed trunks between the NASs and the PSTN switch. The signaling controller does not perform trunk group selection in these solutions.
