Table 5-20. E1 Link1 Parameters
Parameters Possible Values Description
Frame Type G732N
G732S
2 frames per multiframe. Time slot 16 can be used for user data.
16 frames per multiframe. Time slot 16 is used for the Channel
Associated Signaling (CAS).
CRC-4 On, Off Cyclic Redundancy Check – enables or disables calculation of
4-bits check sum in order to detect errors in frames
Sync
FAST
AT&T 62411
CCITT
Defines the time required for the link to return to normal
operation after a red alarm event has terminated.
1 second
10 seconds
100 msec.
Idle Code 00 to FF Sets the value to be transmitted on the NC time slots
Rx Gain 12 dB, 30 dB Sets the maximum receive sensitivity for the E1 interface
Remote Alarm
Indication (for
FCD-IPM with a
Sublink)
When configuring this parameter from the E1 Parameters menu,
select this parameter to determine whether to transmit a yellow
alarm indication on the E1 sublink when Link 1 is in yellow
alarm state.
When configuring this parameter from the Sublink E1
Parameters menu, select this parameter to determine whether to
transmit a yellow alarm indication on Link 1 when sublink E1 is
in either yellow or red alarm state.
Note: When Link 1 is in red alarm state, an “all ones” indication
is sent to all of the E1 sublinks.
Out-Of-Service
Signaling (for
FCD-IPM with a
Sublink)
Mark
Space
Mark-space
Space-mark
Determines the value of the A, B signaling bits sent to Link 1
when the sublink is in the Out-Of-Service state. The C and D
signaling bits are not affected.
Both A and B signaling bits are forced to '1' during out-of-service
period
Both A and B signaling bits are forced to '0' during out-of-service
period
The A and B signaling bits are forced to '1' for 2.5 seconds, then
shift to the '0' state until the out-of-service period ends
The A and B signaling bits are forced to '0' for 2.5 seconds, then
shift to the '1' state until the out-of-service period ends.
