MultiFRAD User Guide

Cabling your MultiFRAD

Cabling your MultiFRAD involves making the proper Power, Command Port, Ethernet, and Channel

(and Voice/Fax, FR221/V2 Only) connections. Figure 2-2 shows the back panel connectors and the

associated cable connections. The MultiFRAD supports two data channels.

Note: Before starting to cable your MultiFRAD (FR221/V2 Only), perform the E&M Jumper Block

Positioning Procedure if either voice/fax channel (1 or 2) will be connected to an E&M trunk that is a

Type 1,3,4, or 5 rather than a Type 2 (the default position).

The following steps detail the procedures for connecting the cables to your MultiFRAD.

1 Connect one end of a DB25 cable to each of the data channel connectors on the back of your

MultiFRAD (labeled CHANNEL 1-2). See Figure 2-2. Connect the other end of each cable to a

channel device.

Note: Both data channels support the RS232/V.35 protocols, and either asynchronous or HDLC

synchronous RS232 data equipment such as multiplexers. Refer to V.35 Shunt procedure in Chapter

2 if it is necessary to switch from the default RS232 interface to V.35 interface.

2 Connect an RJ-45 Link cable from the DSU jack to a Trunk connection of a frame relay network.

3 Connect a network cable to the 10 BASE-T Ethernet connector (shown in Figure 2-2). Connect the

other end of the cable to your LAN.

4 Connect the MultiFRAD to your PC using the short RJ-45 to DB9 (female) cable provided with your

unit. Plug the RJ-45 end of the cable into the Command Port jack (labeled COMMAND) of the

MultiFRAD and the other end into the serial port on the PC.

Note: The E&M, FXS, and Ethernet ports are not designed to be connected to a Public

Telecommunication Network.
