Test Port Control for the RS 32000 and RS 38000 CT3
Each Channelized T3 port has an associated T1 test port, which provides access to any of the DS1 channels within a
Channelized T3 (see
Figure 30-4
). You can configure the test port in either monitor or break-out mode.
•
In
monitor mode
, you may connect an external analyzer to a test port to allow transparent monitoring
of data on a given selected DS1 channel.
•
In
break-out mode
, you can remove the selected DS1 channel from service, which allows you to
connect external test equipment to verify the operation of the DS1 channel. The break-out mode is
mainly intended for support of external BERT equipment (see
Section 30.16.4,
"Bit Error Rate
Testing"
).

Also, a separate DS1 test port connection is provided per T3 interface for the monitoring or break-out testing of an
individual DS1 channel within a channelized T3 group. The DS1 test port connections are provided by RJ-48c
connectors. The test port connections are not provided on the clear-channel modules.
