Chapter 14: 8+8-Port Analog Universal Module
Wave Server Hardware Reference Guide
Physical description
The analog universal module consists of a printed circuit board and a metal faceplate mounted
to the front of the board, as shown in Figure 14-1. The insertion lever on the left side of the
faceplate facilitates the insertion and removal of the module. Each analog universal module
occupies a single slot.

Analog universal module
The analog universal module is powered through its connection to the backplane. The RJ-21X
connector on the front of the analog universal module connects to a standard RJ-21X cable that
terminates on the punchdown block.
For ports configured as analog loop start or ground start trunks, there is also a small amount of
power received through the trunks. For ports configured as analog DID trunks, by contrast, the
analog universal module is responsible for supplying the battery voltage to the CO.
Caution: Connecting the analog universal module to a trunk with voltage present can damage
the module. Before installing the analog universal module, test the incoming DID trunks with a
technician’s test set to ensure that no voltage is present.
