Installing The Panels - Symmetricom TSG-3800 Series User Manual

Installing the TSG-3800
Input/Output Adapter Panels
The input signal connections to the TSG-3800 shelves are grouped by input card
slots; you make connections through seven position wire-wrap terminals. Output
signals and the TIM I/O signals are accessible on female 50-pin connectors on the
rear panel of the units. Each redundant pair of output modules uses 20 pairs (tip &
ring) of pins; the remaining 10 pins are common shield connections. The TIM I/O
connections are on four pairs of the 50 pins for East and West input and output.
Selection of the proper wire-wrap panel and interconnecting cables depends on the
installation configuration and customer preferences.
The 19-inch and 23-inch Output Panels developed for use with the TSG-3800 series
are shown in Figure
