Connecting media bay modules to Service Providers

To connect DTM, CTM, CTM8, 4X16, or BRI media bay modules to the network, follow these steps:

1On the front of the module, locate the RJ48C socket (DTM), RJ45 sockets (BRI), or the RJ11 sockets (CTM and 4X16 modules).

2Wire one end of the cable to the telco demarcation blocks of the building.

• Figure 53 shows the wiring pinouts for a DTM to connect to a service provider.

Warning: If you are using a service provider bus service unit (CSU), you must disable the Business Communications Manager system internal CSU using Business Communications Manager Unified Manager. For more information, refer to the Business Communications Manager Programming Operations Guide.

•Figure 54 shows the wiring pinout for a CTM, a CTM8, or the CTM jacks on a 4X16 module, to connect to the service provider.

All the modules have an auxiliary jack (the CTM8 has two). Do not attempt to plug digital equipment into this jack.
