Mode
T1 Setup
T1 CAS,
T1 PRI,
SS7
Enables/disables loopback test
Pass-Through mode. The Span
activates/ deactivates Pass-
Through upon detection of the
Loop-Up/Loop-Down codes.
Affects Policy enforcement.
When the Pass-Through mode
is On, telecom data is
transmitted without
parsing/monitoring through the
Span and Policy is not
enforced; D-channel re-
establishment and error count
threshold checking/logging is
disabled; Error count value of
0 is sent to the Management
Server. When the Pass-
Through mode is Off, telecom
data is routed through the Span
and Policy is enforced. When
the Pass-Through mode is set
to Autodetect, Pass-Through is
activated when a Loop Up
code is detected and
deactivated when a Loop-
Down code is detected. When
Autodetect is selected, you can
specify a timeout value.
