Performing a Tributary Scan
Description
Verifying an ADM Installation
The OmniBER 720's tributary scan feature allows you to quickly test the routing of
VC-n/STS-1 paths through digital cross connects and ADMs (when the tributary
interfaces are synchronous). It does this by automatically testing each path through
the network element for bit errors or a pattern loss. The example given below is
applicable for both SONET and SDH applications.
Tributary Scan tests each tributary for error free operation and no occurrence of
Pattern Loss. A failure is indicated by highlighting the tributary in which the failure
occurred. The

tributary structure. The OmniBER 720 will configure the Transmitter to the
Receiver and the PATTERN is forced to the payload it will fill.
