Connecting The System 4.1 Connecting The Lines How to connect the linesLine terminations to the line boards vary depending upon the line board type. Terminations for the loop start board are standard modular jack connections. Each jack on the loop-start board provides termination for two lines. Terminations for the loop start and the multipurpose boards are through a 50-pin amphenol-type connector, and the connection for the T1 board is an eight-pin modular jack. The demarcation point can be a type 66M-xx connector block or individual 6-position modular jacks. The wiring that you route between the demarcation-point and the line board termination should be #24 AWG or larger twisted-pair wiring (see figure 14 for line board connections). How to protect the linesTransient voltage spikes, if induced onto CO or CENTREX lines, can travel through the cable and into the common equipment. The telephone company offers basic protection against this condition, but it is usually designed to protect the central office circuits. While this CO or CENTREX service will also provide some protection to the common equipment, you should not rely upon it for total protection. To help ensure that external over-voltage surges do not damage the system, Comdial recommends that you install and properly ground gas discharge tubes, or similar primary protection devices, on all lines. Each line board is shipped with a ferrite collar. Bundle the line cables together and snap the collar around the bundle to provide protection against radio frequency interference. 4 GCA40–130 DXP Plus General Description 28 – Connecting The System

4.2 Connecting The Stations How to connect the stationsConnections between the telephones and the station boards are typically via type 66M-xx connector blocks that are cable connected to the station boards (see figure 15). The gauge size of the twisted-pair station wiring determines the maximum distance allowed from the common equipment to the stations.

Each station interface board is shipped with an appropriate supply of ferrite collars. Snap one of these around each station cable to provide protection against radio frequency interference. Installing a DSS / BLF consoleInstall a DSS/BLF Console at any station in the system as a companion to a telephone. There is no limit to the maximum number of consoles that can be installed on a system. When you install a console, you must also define the station as a console with programming.

4.3 Connecting The Paging Equipment And Music Sources The services board provides a standard 6-position modular jack for interfacing external paging equipment and external music sources to the DXPPlussystem. This jack supplies audio output from the DXPPlusfor paging purposes and accepts audio input from two separate audio sources. See Figure 16 for details.

4.5 Connecting The Serial Data Ports The CPU board provides two serial data ports dedicated for PC-based programming and the remote-maintenance modem. You can add as many as 16 additional non-dedicated serial data ports by adding the communications card onto either the services board, the auxiliary board, or either of the two interface boards. Each of these boards will accept up to two communications cards onto its lower two slots. The following chart shows the locations for all of the non-dedicated serial data ports (Figure 18 shows the pin-outs for serial data ports). Serial Data Port Designation DXOPT–COM Location Serial Data Ports 3–10 Lower two slots on the services board Serial Data Ports 11–18Lower two slots of one of the following: —The interface board in the upper expansion cabinet, —The interface board in the lower expansion cabinet, —The auxiliary board in the main cabinet. In order to use all 16 non-dedicated serial data ports you must install four communications cards.
