Field Name Description

FDL Standard Specify if you want to use the ATT 54016 standard (TR54016), the ANSI T1.403

standard (T1.403), or both. Make the selection required by your carrier, if any.

FDL Mode Specify terminated (TERM). (PASS) does not apply to the QUAD/IMUX.

Poll Mode Specify if you want FDL to poll (POLL), not poll (NO POLL), or accept unsolicited

information (UNSOLICIT).

• POLL: The near-end CSU automatically polls the far-end CSU for alarms every 4

seconds and reports these alarms. Functions only if the FDL portion of the ESF

framing is routed through any DACS in the T1 network.

• NO POLL: Disables alarm polling at both ends. Select this option when the nodes

at both ends are connected and both nodes report local alarms.

• UNSOLICIT: The QUAD 2164 automatically sends its alarm status (when it

detects an LOS) to the far-end.

PRM C/R bit The Performance Report Message Command/Response as defined in the ANSI

T1.403 specification.

Specify USER to set the bit to 0, indicating the PRM source terminal. Specify TELCO

to set the bit to 1, indicating the Telco is the PRM source. Phone companies usually

set to TELCO, non phone companies set to USER. If you do not wish to set it to

either USER or TELCO, choose NONE.

Idle Pattern Selects the idle pattern code for the 4K FDL portion of the ESF framing. The Idle

Pattern is sent when there is no other FDL traffic. Depending on your network,

select either ALL ONES or FLAGS. The selected signal is transmitted continuously

until a message is sent. Upon message completion, it reverts to the signal of

choice:

• ALL ONES is a signal on an FDL comprised entirely of ones: 11111111.

• FLAGS is a signal on an T1 FDL line comprised of 01111110.

Send/Rec LLB BOP Enable Line Loopback Bit-Oriented Protocol (LLB BOP) if you want to use FDL

loopbacks to test the T1 line.

Send/Rec PLB BOP Enable Payload Loopback Bit-Oriented Protocol (PLB BOP) if you want to use FDL

loopbacks to test the CSU from the far-end circuit.

Exit this screen Use this option to return to the Main Menu.
