Nortel Integrated Conference Bridge Service Implementation Guide
In the procedures that follow, the connections are the same for the
Option 11C and the CS 1000, the only difference is that the connectors
are on the back of the Call Server and Media Gateway for the CS 1000,
whereas they are on the bottom of the Option 11C cabinet.
Table 13 describes the DB-9 pin assignment that the next two
procedures use.
Procedure 8
Access the ICB directly – Option 11C or CS 1000
1Position the Maintenance terminal on a desk near the system.
2If the system is an Option 11C perform the following:
aVerify that the Ethernet Adapter is installed in the Option 11C.
bPlug the terminal cable DB-9 female connector into the DB-9 male
connector on the Ethernet Adapter on the I/O panel.
cPlug the DB-25 male connector at the other end of the terminal cable into
the RS-232 connector on the terminal. If the connection requires a
gender changer, obtain one at a local electronics store.
3If your system is a CS 1000, connect the NTBK48 three-port SDI cable to the
9-pin SDI connection (COM RS-232) at the back of the Call Server and Media

Gateway.
Procedure 9
Access the ICB remotely using a modem – Option 11C or CS 1000
1Verify that the Ethernet Adapter/Medium Access Unit (MAU) is installed in the
Option 11C or CS 1000. Insert the industry-standard MAU into the Ethernet
Connection on the back of the Call Server and Media Gateway.
Note: The Ethernet MAU comes with the cable kits for the Call Server and Media
Gateway.
2Plug the terminal cable DB-9 female connector into the DB-9 male connector
on the Ethernet Adapter/MAU on the I/O panel.
