faw
The 8 bit value to be used for any E1 frame alignment word bit positions that are not
modified by other options. This allows the spare bit designated "For International Use"
to be set by the user when CRC4 mode is disabled. Valid values are 0x9b or 0x1b.
When using T1, this parameter must be set to zero. [E1 default = 0x9b].
nfaw
The 8 bit value to be used for any E1 non-frame alignment word bit positions that are
not modified by other options. Normally, this parameter is set to 0x9f for E1 operation
and set to zero for T1.
ais_gen
The (initial) mode used to generate the Alarm Indication Signal (Blue Alarm) taken
from the following table. The user may subsequently modify the setting of the outgoing
signal using the LIU_MSG_CONTROL message.
ais_gen
Description
1
Disabled - do not generate AIS / Blue alarm.
2
Enabled - generate AIS / Blue alarm.
rai_gen
The (initial) mode used to generate the Remote Alarm Indication (Yellow Alarm) taken
from the following table. The user may subsequently modify the setting of the outgoing
RAI alarm using the LIU_MSG_CONTROL message.
rai_gen
Description
1
Disabled - do not generate RAI / Yellow alarm.
2
Forced active - generate RAI / Yellow alarm.
3
Automatic generation of RAI / Yellow alarm upon loss of
synchronization.
clear_mask
For use with T1 interfaces and line_code mode 3 (AMI with Zero Code Suppression) to
disable zero code suppression on selected channels. This parameter is a 32 bit mask.
Zero code suppression may be disabled for the signaling channel timeslot by setting
the appropriate bit in the mask. The least significant bit corresponds to timeslot 0 and
the most significant bit to timeslot 31. Bits are set to 1 to disable zero code
suppression.
Status Response
The confirmation message (if requested) indicates success by status of zero.
On error, the following status values can be found in the confirmation message.
Value
Mnemonic
Description
0x01
None
Invalid framer ID.
0x02
None
Invalid message length.
