Frame Generator Module Switches and Jumper Locations

Selecting the Clock Frequency
The T1/E1 Frame Generator module with SSM provides two clock outputs. Each
output can be independently set to provide 8 kHz, 1.544 MHz or 2.048 MHz. A
jumper on W9 selects the CLK1 output frequency, and a jumper on W10 selects the
CLK2 output frequency. The frequency of each position is shown on the right side of
each header. Install the jumper across the header in line with the desired frequency.
Setting Switch Block S1
The switch blocks S1 and S2 each contain six rocker switches. S3 contains four
rocker switches. The number of each rocker is located on both sides of the switch
block, 1 through 4, or 1 through 6. A switch is OFF when the left side of the rocker is
pressed down. A switch is ON when the right side of the rocker is pressed down.
