Configuring FDL Messages

To configure T1 channels to send FDL messages:

Specify a T3 interface.

host1(config)#

controller t3 8/0

Specify the standard for transmission of FDL messages on both ends of the T1
connection.

host1(config-controll)#

t1 1 fdl ansi

(Optional) Configure one or more T1 channels to operate in an FDL carrier
environment.

host1(config-controll)#

t1 1 fdl carrier

(ANSI signals) Specify the FDL messages.

host1(config-controll)#

t1 1 fdl string eic "ERX1410"

host1(config-controll)#

t1 1 fdl string fic "HY0019"

host1(config-controll)#

t1 1 fdl string lic "Bldg 10"

host1(config-controll)#

t1 1 fdl string unit 080001

host1(config-controll)#

t1 1 fdl string pfi "Site 25"

host1(config-controll)#

t1 1 fdl string port 0800

host1(config-controll)#

t1 1 fdl string generator "Test generator"

Enable transmission of FDL messages.

host1(config-controll)#

t1 1 fdl transmit path-id

(Optional) Specify that the router should generate yellow alarms for the T1 channels.

host1(config-controll)#

t1 1 yellow generate

(Optional) Specify that the router should detect yellow alarms for the T1 channels.

host1(config-controll)#

t1 1 yellow detect

t1 fdl

•

Use to specify the FDL standard for the channel.

•

Specify one or more T1 channels or a range of channels in the range 1–28.

•

Specify the keyword

ansi

to support the ANSI FDL standard (see “References” on

page 9).

•

Specify the keyword

att

to support the AT&T FDL standard (see “References” on

page 9).

•

Specify the keyword

all

to support both the ANSI and AT&T standards

•

Specify the keyword

none

to remove the current FDL mode settings

•

You can configure a different standard on each T1 channel.

•

Example

host1(config-controll)#

t1 14-20,24 fdl att
