C. Configuration Options
Table C-2. Network Interface Configuration Options (2 of 3)
C-4
NET LLB: Enab
Next Enab Disab Prev
Network Initiated Line Loopback (LLB). Allows initiation and termination of the LLB to be
controlled by the receipt of LLB-Actuate and LLB-Release commands from the network
(or remote CSU).
–
Enab Causes the CSU to enter an LLB (if the CSU can perform an LLB in its current
state) and to cause an LLB-Release command to terminate the LLB.
–
Disab Causes the CSU to ignore LLB-Actuate and LLB-Release commands (the CSU
is not in compliance with ANSI T1.403 and AT&T TR 62411).
NOTE: When this configuration option is enabled, the CSU recognizes the in-band
LLB-Actuate and LLB-Release codes specified by AT&T as well as the bit-oriented FDL
messages specified by ANSI (for ESF only).
NET PLB: Enab
Next Enab Disab Prev
Network Initiated Payload Loopback (PLB). Allows initiation and termination of the PLB to
be controlled by the receipt of PLB-Actuate and PLB-Release commands from the
network (or remote CSU).
–
Enab Causes the CSU to enter a PLB (if the CSU can perform a PLB in its current
state) and to cause a PLB-Release command to terminate the PLB.
–
Disab Causes the CSU to ignore PLB-Actuate and PLB-Release commands (the CSU
is not in compliance with ANSI T1.403 and AT&T TR 54016).
NOTES:
– When this configuration option is enabled, the CSU recognizes the in-band
PLB-Actuate and PLB-Release codes specified by AT&T as well as the bit-oriented
FDL messages specified by ANSI.
– This configuration option is only available when the network interface framing is set
to ESF.
Bit Stuff: 62411
Next 62411 Disab Prev
Bit Stuffing. Determines when bit stuffing is performed to meet the ones density
requirements for data transmission on the network. You must choose the maximum
number of consecutive zeros the CSU can receive before it inserts a one.
–
62411 Specifies that a one be inserted in the data stream after 15 consecutive zeros or
when the density of ones falls below 12.5% (complies with AT&T TR 62411).
–
Disab Disables bit stuffing so that ones density is not enforced.
NOTES:
– To comply with Canadian DOC CS-03 regulations, equipment installed in Canada
must be configured to select 62411.
– This configuration option is only available if the network interface line coding format
is set to AMI.
