Cisco 7200/7400 Series Manager enables you to create and delete logical voice interfaces. The logical interfaces created are voice ports (DS0, PRI, or TDM groups) and serial interfaces (channel groups). A group is a set of time slots bundled under a specific identifier (group number). T1 configurations support a maximum of 24 groups and E1 configuration up to 31 groups.
Use DS1 Extended Controller Configuration window to configure logical interfaces.
To open DS1 Extended Controller Configuration window:
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears with the DS0 group tab displayed.
Step 2 Click the PRI Group tab to view PRI group information, the TDM Group tab to view TDM group information, and the Channel Group tab to view channel group information.
Managing DS0 Groups
Digital service level 0 (DS0) represents a 64-kbps single-channel signal generated by a T1 terminal device such as a channel bank, multiplexer (MUX), or digital PBX. Cisco 7200/7400 Series Manager enables you to create or delete DS0 groups.
You can configure MCX controllers for voice or data transmissions. Possible configurations include common channel signaling (CCS) voice, channel associated signaling (CAS) voice, or data. Before creating a DS0 group, you must configure the service type of the MCX controller.
To configure the service type for MCX controllers:
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears.
Step 2 Select the service tab type.
Step 3 From the list on the left side of the window, select the interface.
Step 4 Select a service type configuration (CCS, CAS, or Data)
Step 5 Click Save.
The MCX controller service type is configured.
Note You can configure the service type of other cards by repeating Steps 2
and 3.
Creating a DS0 Group
Before creating a DS0 group, ensure that you have configured the multichannel port adapter service type.
To create a DS0 group:
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears.
Step 2 Select DS0 Group tab.
Figure 11-1 DS1 Configuration Window (DS0 Group Tab)
Step 3 From the list on the left side of the window, select interface.
Step 4 Enter a valid and available time slot, or range of time slots, in the corresponding fields.
Step 5 Enter a valid and available group number in the corresponding field.
Step 6 Choose the signaling type from the corresponding option button.
Step 7 Click Create, and refresh the display.
A new interface group is added to the displayed list in the upper portion of the window. The selected data is reflected in the Interface Status list.
Deleting a DS0 Group
Note You cannot delete individual time slots within a group. You must delete the
entire group and then recreate the group with the desired time slot.
To delete a DS0 group:
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears.
Step 2 Select the DS0 Group tab.
Step 3 From the list on the left side of the window, select the interface.
Step 4 Select the DS0 group.
Step 5 Click Delete, and refresh the display.
The selected interface group is removed from the displayed list in the upper portion of the window.
Managing PRI Groups
ISDN is an interface to the PRI. PRI provides access through a single 64-kbps D channel plus 23 (T1) or 30 (E1) B channels for voice or data. Cisco 7200/7400 Series Manager allows you to create or delete PRI groups.
You must configure the ISDN switch type before creating a PRI group.
To configure the ISDN switch type:
Step 1 Telnet to the router.
Step 2 At the CLI prompt, enter:
config terminal
isdn switch-type <switch name>
Replace the switch name variable in the command with one of the following switch names:
primary-4ess (Lucent 4ESS switch type for the United States)
primary-5ess (Lucent 5ESS switch type for the United States)
primary-dms100 (Northern Telecom DMS-100 switch type for the United States)
primary-net5 (NET5 switch type for the United Kingdom, Europe, Asia, and Australia)
primary-ni (National ISDN switch type for the United States)
primary-ntt (NTT switch type for Japan)
primary-qsig (QSIG switch type)
primary-ts014 (TS014 switch type for Australia [obsolete])
Creating a PRI Group
Before creating a PRI group, ensure that ISDN switch type is configured.
To create a PRI group:
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears.
Step 2 Select the PRI Group tab.
Figure 11-2 DS1 Configuration Window (PRI Group Tab)
Step 3 From the list on the left side of the window, select the interface.
Step 4 Enter a valid and available time slot in the corresponding field.
Step 5 Click Create, and refresh display.
The new interface group is added to the list in the upper portion of the window. The entered time slot is reflected in the Interface Status list. The system-assigned group number and the ISDN signaling type is updated.
Deleting a PRI Group
When a PRI group deletion is initiated, the controller is automatically shut down.
Note You cannot delete individual time slots within a group. You must delete the
entire group and then recreate the group with the desired time slot.
To delete a PRI group:
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears.
Step 2 Select PRI Group tab.
Step 3 From the list on the left side of the window, select the interface.
Step 4 Select the PRI group.
Step 5 Click Delete, and refresh the display.
The selected interface group is removed from the displayed list in the upper portion of the window.
Managing TDM Groups
Time-division multiplexing (TDM) allows for information from multiple channels to be allocated bandwidth on a single wire based on preassigned time slots, therefore enabling simultaneous support for voice, data, and video transmission over a single network link. Pieces of data from each signal are interwoven into a single link transmission, and reconstructed at the destination point.
TDM groups are made up of cross-connects referred to as clear channel groups or pass through. Cisco 7200/7400 Series Manager allows you to create and delete TDM groups.
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears.
Step 2 Select the TDM Group tab.
Figure 11-3 DS1 Configuration Window (TDM Group Tab)
Step 3 Select the interface from the list on the left side of the window.
Step 4 Enter a valid and available time slot in the corresponding field.
Step 5 Enter a valid and available group number in the corresponding field.
Step 6 Click Create, and refresh the display.
The new interface group is added to the list in the upper portion of the window. The entered data is reflected in the Interface Status list.
Deleting a TDM Group
Note You cannot delete time slots within a group. You must delete the group and
then recreate the group with the desired time slot.
To delete a TDM group:
Step 1 Right-click an object, and choose CERM Management > Logical > Voice Management > DS1 Configuration. The DS1 Extended Controller Configuration window appears.
Step 2 Select the TDM Group tab.
Step 3 Select interface from the list on the left side of the window.
Step 4 Select the TDM Group from the list.
Step 5 Click Delete, and refresh the display.
The selected interface group is removed from the list in the upper portion of the window.
Managing Channel Groups
A channel is the smallest subdivision of a communication path on a digital, multiplexed signal for which information can be provided in one direction.
Multiple channels can be multiplexed over a single cable in certain environments. Channel groups also referred to as serial interfaces. Cisco 7200/7400 Series Manager enables you to create and delete channel groups.
The DS1 Extended Controller Configuration window contains five tabs: DS0 Group, PRI Group, TDM Group, Channel Group, and Service Type.
