6.2.6.2 Module Installation

For DSX or CEPT operation, you must install one of these modules on the associated WAN

card before inserting those cards into the system chassis. Figure 6-1 shows the locations of the

DSX/CEPT modules on a WAN card. One module is required per WAN port. If your system

has a T1 link (DSX) and an E1 link (CEPT), you will need two DSX/CEPT modules.

First, install a DSX/CEPT module in the slot reserved for WAN port 1-1. Insert the pins for

TX into socket JP10 on the WAN card (see Figure 6-1), while also inserting the pins for RX

in JP9 and the 24-pin end connector pins in JP6. Then, for a WAN DUAL card, install another

DSX/CEPT module in the WAN port 1-2 location, and plug that module into JP13, JP14, and

JP15.

6.2.6.3 Revision F Module

The DSX/CEPT Revision F module is shown in Figure 6-2 through Figure 6-7. There are two

different types of modules (see illustrations below). These modules may be optioned for T1,

120-ohm balanced E1, or 75-ohm unbalanced E1. The jumper option configuration is shown

on the card itself. The jumpers shown here are set for 75-ohm unbalanced E1 operation.
