Overhead Analyzer: Displays the Section/Line Overhead (SOH) and STS Path Overhead (POH) bytes of the
received channel.
Overhead Generator: Used to edit Section/Line Overhead (SOH) and STS Path Overhead (POH) bytes of the
received channel.
Pointer Tasks: Displays both STS and VT pointer values and generates STS and VT pointer movements.
Pointer sequences according to Bellcore GR.253 recommendations are also possible.
Trace Identifier: Used to generate and edit J0, J1 and J2 path traces and set expected trace for received channel
according to G.831 recommendations.
Payload Labels: Used to set the C2 and V5 Path Signal Labels which indicate the content of the STS path and
VTs.
APS Testing: Used to measure Automatic Protection Switching limits. Using selectable triggers, the drop out
times of tributary connections are measured and compared with preset values.
TCM Tasks: Used to analyze or edit the sequence of Z5 and Z6 TCM bytes by generating alarms and errors in
the Tandem connection sub-layer.
Tributary Scan: Used to scan individual or multiple tributaries to verify routing and error free operation.
Available in VT-1.5 or VT-2 mode
Round Trip Delay (Propagation Delay): Measurement works by sending a test pattern. Bit errors are
transmitted in the pattern. The time it takes for the error to reach the receiver is the propagation time through the
network.
