2048 kHz Output Module
This section provides operating instructions and software provisioning procedures
for the 2048 kHz Output module (part number 23413159-000-0). It also contains
default provisioning settings, and procedures for connecting to the SSU-2000e in
order to enable, provision, and disable the module.
Functional Overview
The 2048 kHz Output module receives a set of three (four if installed in an
expansion shelf) 4 kHz clocks from the Clock modules and uses these clocks to
develop an 8.192 MHz phase-locked signal. This phase-locked signal is then used
to generate 20 sets of 2048 kHz clock outputs.
