Signal Connections

Input Signals
The RS-422 Selective Rate Clock module automatically operates from any framer
unit configuration. The module detects the input from the framer unit and divides it
by the appropriate number to generate an 8 kHz signal. Each of ten independent
synthesizers is locked to this frequency and can be programmed to the selected
output frequency for that particular port.
Output Signals
The output signals are available at the 50-pin connectors located on the rear panel
of the shelf. Table 7-37
to Making Output Signal
Caution: To prevent damage to the unit and to insure proper
operation, unused connections must be left open .

Operational Check

When the RS-422 Selective Rate Clock module is installed and power is applied to
the shelf, all LEDs and seven segment displays turn on for a lamp test.
Note: If any display fails to turn on, the unit will not give correct
indications and should be returned for repair.
