ACCULINK 315x CSU
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).
NOTE: 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.
NOTE: 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 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 – 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.
NOTE: To comply with Canadian DOC CS-03 regulations, equipment installed in Canada must be configured to select
62411.
NOTE: To comply with USA Part 68 regulations, equipment installed in the USA must be configured to select Part 68.
NOTE: This configuration option is only available if the network interface line coding format is set to AMI.
Keep Alive: AIS
Next AIS One NetLp
Network Keep-Alive Signal. Specifies the type of keep-alive signal to be transmitted to the network interface when a valid
signal cannot be recovered from the DTE interface (LOS or continuous OOF), or the CSU is otherwise incapable of
sending a valid signal.
AIS – Sends an unframed all ones signal to the network in case of an unrecoverable DTE signal. This complies with
AT&T 62411 and FCC Part 68.
One – Sends a framed all ones signal to the network in case of an unrecoverable DTE signal. This complies with FCC
Part 68 only.
NetLp – Loops back the received network signal in case of an unrecoverable DTE signal. This complies with FCC Part 68
only.
