Configuration Option Tables

Table A-2. Network Interface Options (3 of 4)

FDL Subnet Mask

Possible Settings: 000.000.000.000 ± 255.255.255.255, Clear

Default Setting: 000.000.000.000

Specifies the subnet mask used to access the unit via the FDL interface.

000.000.000.000 ± 255.255.255.255 ± Set the FDL interface subnet mask. The range for each byte is 000 to 255.

Clear ± Clears the FDL Subnet Mask and sets to all zeros. When the subnet mask is all zeros, the device creates a default subnet mask based on the class of IP address:

±Class A defaults to 255.000.000.000

±Class B defaults to 255.255.000.000

±Class C defaults to 255.255.255.000

Network Initiated Line Loopback (LLB)

Possible Settings: Enable, Disable

Default Setting: Enable

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).

Enable ± 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.

Disable ± 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: If 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).

Network Initiated Payload Loopback (PLB)

Possible Settings: Enable, Disable

Default Setting: Enable

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).

Enable ± 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.

Disable ± 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: ± If 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 if the network interface framing is set to ESF.
