Fdl Address
One of two Facility Data Link (FDL) target address
modes. It determines whether the near-end FDL will
respond to High Level Data Link Control (HDLC) address
AZ or BY in the FDL messages received from the far end.

respond to High Level Data Link Control (HDLC) address
AZ or BY in the FDL messages received from the far end.
Fdl Type
Attribute used to configure the FDL type. The ANSI403
configures the port to use the FDL exchange described in
the ANSI T1 403 specification. ATT54016 is used to
configure the port for the FDL exchange listed in the
AT&T 54016 document. NONE is used when no FDL is
desired. The FDL can only be used when the line type is
ESF.

Fdl Prm Cr Send/Accept
Performance message as originating from either a carrier
or customer installation (CI). As the performance
message is sent out the FDL, the PRM Opening Address
Cr bit is either set (Carrier) or cleared (CI).

Fdl Loop Retention
Loop retention interframe time fill for the FDL after
sending loopup code. Also, displays whether the DS1
requires a loop retention code to be sent after a loopup
request.

Accept Loopbacks
Whether the DS1 will accept or reject loop code requests

Loopback State
Current loopback state of this interface. The interface can
be in one the following states: payload loopback, line
loopback, or no loopback.

Loopback Action
Whether the DS1 was sent into either line loopback or

device. Possible values are: sendnocode, sendlinecode,
sendpayloadcode, sendqrs, and sendothertestpattern.
