Determine if you require a BITS timing source connection to the chassis;
if so, the chassis must first have a line termination prior to chassis
connection.
The BITS concept is used for interoffice synchronization distribution.

this termination through external termination blocks (product catalog
TERM-100) placed on wire-wrap terminal posts on the rear of the
ThinMux chassis as shown in
.
