Figure 501-1

.

The chassis backplane is shown in

Figure 501-2

.

1. See

Figure 501-1

to identify module locations at the front of the chassis. A working DS3

MUX module, an APU, and an MPU are always required. The slots identified for low-
speed modules can house:

Up to 14 ODS2 modules (7 working and 7 protect),

28 HLXC modules,

28 DLX modules,

28 RLX modules, or

Any combination up to a maximum of 28 DS1 circuits.

2. See
