Installing The Office Module - MCK EXTender 3000 System Administrator Manual

Installing the Office Module

Ensure that you have the EXTender 3000 Module (module is labeled 'Switch Module' on the cover) before
proceeding. To configure and connect your EXTender 3000, see the figure below. Ensure that the maximum
length of your cable between the PBX and the Office Module does not exceed 150 metres (500 feet).
Caution: Do not connect a digital telephone to a Office Module.
RJ45 Digital Line
PBX or Key System
1. Connect the ISDN BRI line from your PBX or a central office (CO) line to the ISDN jack of the Office
Module at the on-premise location. Use the RJ45 cable, included with the system.
Ensure you connect an ISDN ST interface Office Module to ST interface line or an ISDN U interface
Office Module to U interface line. A quick way to check the type of ISDN interface on your office mod-
ule is to determine which way the line leads on your RJ45 cable are pointing if you were to insert the
cable into office module. The cable line leads point "up for U" (point down for ST). The U interface
connector is orientated the same as the digital port and Ethernet connectors.
2. Connect the Office Module SWITCH jack to the 2-wire digital port on the PBX using a standard phone
cable.
3. If you are using Ethernet data, connect the Ethernet jack on the Office Module to the Ethernet jack at the
on-premise location. Use a standard Ethernet cable. Refer to the Data Configuration section of this doc-
ument to set the Ethernet data type operation.
4. If you are using Serial or Dial up data, connect the RS-232 jack on the Office Module to the on-premise
PC or Data Communications Server. Use a straight-through RS-232 cable. You may need an adapter if
your equipment does not have a 9-pin connector.
