16 — E1 circuit operating parameters
16.1
E1 signaling type
Signaling refers to the codes and protocol for call setup, call tear-down and status
information between two devices over a primary rate link. The signaling type defines
how signaling information is exchanged with the far-end device.
The signaling type choices are:
•
transparent signaling (SIG)
•
clear channel signaling (NoSIG)
For transparent signaling, signaling is passed without being tested for compatibility
with the far-end signaling type. For clear channel signaling, a 64 kb/s clear channel
is created for which signaling is not passed.
Procedure 16-1 To configure E1 circuit signaling type
where p is 1 or 2, and c is 1 to 31
* Default
16.2
E1 fault signaling
Fault signaling is the signaling code that the node applies to an interface when the
interface to which it is cross-connected is not available.
The options are:
•
seized
•
idle
•
out-of-service type A
•
out-of-service type B
•
out-of-service type C
•
no trunk conditioning for circuit
All primary rate circuits can be configured to appear seized or idle (default) to the
outside world.
