3160-A2-GB24-10
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 DSU/CSU).
Enab – Causes the DSU/CSU to enter an LLB (if the DSU/CSU can perform an LLB in its
current state) and to cause an LLB-Release command to terminate the LLB.
Disab – Causes the DSU/CSU to ignore LLB-Actuate and LLB-Release commands (the
DSU/CSU is not in compliance with ANSI T1.403 and AT&T TR 62411).
NOTE: When this configuration option is enabled, the DSU/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 DSU/CSU).
Enab – Causes the DSU/CSU to enter a PLB (if the DSU/CSU can perform a PLB in its
current state) and to cause a PLB-Release command to terminate the PLB.
Disab – Causes the DSU/CSU to ignore PLB-Actuate and PLB-Release commands (the
DSU/CSU is not in compliance with ANSI T1.403 and AT&T TR 54016).
NOTES:
– When this configuration option is enabled, the DSU/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 Part68
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 DSU/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).
Part68 – (Model 3164 only.) Specifies that a one be inserted in the data stream after
80 consecutive zeros (complies with FCC Part 68).
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.
– To comply with USA Part 68 regulations, equipment installed in the USA must be
configured to select Part 68.
– This configuration option is only available if the network interface line coding format
is set to AMI.
