fdl [ansi | att | none]
Use the
fdl
command to configure the format for the facility data link (FDL) channel on the T1 circuit.
FDL channels are only available on point-to-point circuits. Use the
no
form of this command to return to
the default value.
Syntax Description
ansi
Configures the FDL for ANSI T1.403 standard.
att
Configures the FDL for AT&T TR 54016 standard.
none
Disables FDL on this circuit.
Default Values
By default, the FDL is configured for
ansi
.
Functional Notes
T1 circuits using ESF framing format (specified using the
framing
command) reserve 12 bits as a data link
communication channel, referred to as the FDL, between the equipment on either end of the circuit. The
FDL allows the transmission of trouble flags such as the Yellow Alarm signal. See
page 703 for related information.
Usage Examples
The following example disables the FDL channel for the T1 circuit:
ProCurve(config)#
interface t1 1/1
ProCurve(config-t1 1/1)#
fdl none
