Configuring FDL
Facility Data Link (FDL) is a far-end performance reporting tool. In ANSI mode, you can enable one-second
transmissions of performance reports on both ends of the T1 connection. To configure FDL, use the following
commands:
Purpose
Command
Enters global configuration mode.
Router#
configure terminal
Selects the controller to configure and enters interface
configuration mode.
Router(config)#
controller t3 slot/subslot/port
(Optional) Enables FDL.
•
number
—
Specifies the T1 channel number.
•
ansi
—
Specifies the FDL bit per the ANSI
T1.403 specification.
Router(config-controller)# t1 number fdl {ansi}
Verifying FDL
Use the show controller command to display the FDL setting:
Router# show controller t3 3/0/1/1
T3 3/0/1 is down.
