Installing The Timing Insertion Module - Symmetricom TSG-3800 Series User Manual

Setting the Slip Reset Switch
A slip fault (SLIP) or an output fault (FAULT) can be cleared by pressing the RESET
switch.
Monitors
The DS1 signals can be monitored at the front panel as follows:
EAST IN
EAST OUT (re-timed)
WEST (through)
TIM Bypass Relay Assembly
The TIM Bypass Relay Assembly is plugged into the adjacent output slot of the shelf
to provide an alternate signal path in case the TIM is removed for service. When the
TIM is operational, the relays are opened to allow the signals to be routed through
the re-timing and monitoring functions of the TIM. When the TIM is in "BYPASS"
mode or is removed from the shelf, the relays close, bypassing both the East and
West signal paths from input connections to output connections. The TIM then can
be removed for service without disrupting the signals.

Installing the Timing Insertion Module

The Timing Insertion module is designed to operate singly. Insert the module in a
primary distribution slot. Insert the TIM Bypass Relay Assembly into the
corresponding secondary distribution slot.
