Procedure 8
Access the MICB directly – Succession 1000, Succession 1000M
Cabinet, and Meridian 1 Option 11C Cabinet
1 Position the Maintenance terminal on a desk near the system.
2 If the system is a Succession 1000M Cabinet or Meridian 1 Option 11C
Cabinet, perform the following:
a Verify that the Ethernet Adapter is installed.
b Plug the terminal cable DB-9 female connector into the DB-9 male
connector on the Ethernet Adapter on the I/O panel.
c Plug 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.
3 If your system is a Succession 1000, connect the NTBK48 three-port SDI
cable to the 9-pin SDI connection (COM RS-232) at the back of the
Succession Call Server and Succession Media Gateway.
Procedure 9
Access the MICB remotely using a modem – Succession 1000,
Succession 1000M Cabinet, and Meridian 1 Option 11C Cabinet
1 Verify that the Ethernet Adapter/Medium Access Unit (MAU) is installed.
Insert the industry-standard MAU into the Ethernet Connection on the back
of the Succession Call Server and Succession Media Gateway.
Note: The Ethernet MAU comes with the cable kits for the Succession Call Server
and Succession Media Gateway.
2 Plug the terminal cable DB-9 female connector into the DB-9 male connector
on the Ethernet Adapter/MAU on the I/O panel.
3 Plug the DB-25 male connector at the other end of the terminal cable into the
DB-25 female connector of the customer-supplied DB-25F/DB-25M
nullmodem adapter.
4 Plug the DB-25 male connector of the DB-25F/DB-25M nullmodem adapter
into the DB-25 female connector on the modem.
5 Insert the modular RJ11 plug into the RJ11 jack on the modem.
