Configuring FDL Messages

To configure T1 channels to send FDL messages:

1. Specify a T3 interface.

   host1(config)#controller t3 8/0

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

   host1(config-controll)#t1 1 fdl ansi
   

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

   host1(config-controll)#t1 1 fdl carrier

4. (ANSI signals) Specify the FDL messages.

   host1(config-controll)#t1 1 fdl string eic "ERX-1410"

   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"

5. Enable transmission of FDL messages.

   host1(config-controll)#t1 1 fdl transmit path-id

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

   host1(config-controll)#t1 1 yellow generate

7. (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).
• Specify the keyword att to support the AT&T FDL standard (see References).
• 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

• Use the no version to restore the default, none.
• See t1 fdl.

t1 fdl carrier

• Use to specify that T1 channels are used in the carrier environment.
• Example

  host1(config-controll)#t1 6 fdl carrier

• Use the no version to restore the default situation, in which the T1 channels do not operate in the carrier environment.
• See t1 fdl carrier.

t1 fdl string

• Use to specify an FDL message as defined in the ANSI T1.403 specification.

  Note: The router sends these FDL messages only if you have issued the t1 fdl command with the ansi or all keyword and then issued the t1 fdl transmit command.

• Example

  host1(config-controll)#t1 6 fdl string eic "ERX-1440"

• Use the no version to restore the default value to the specified FDL message or to all FDL messages.
• See t1 fdl string.

t1 fdl transmit

• Use to configure the router to send the specified type of FDL message.
• By default, the router sends only FDL performance data messages.

  Note: The router sends FDL messages specified with t1 fdl string only if you have issued the t1 fdl command with the ansi or all keyword. If you specified the att keyword with the t1 fdl command, the router sends only performance data.

• Specify the keyword path-id to transmit path identifications every second.
• Specify the keyword idle-signal to send idle signals every second.
• Specify the keyword test-signal to transmit test signals every second.
• Example

  host1(config-controll)#t1 28 fdl transmit path-id

• Use the no version to disable transmission of the specified FDL message or all FDL messages.
• See t1 fdl transmit.

t1 yellow detect

• Use to detect yellow alarm for T1 channels.
• By default, T1 channels detect alarms.
• Example

  host1(config-controll)#t1 6,10-14,19 yellow detect

• Use the no version to disable detection of yellow alarms.
• See t1 yellow.

t1 yellow generate

• Use to generate a yellow alarm when a loss of frame or loss of signal condition is detected on T1 channels.
• By default, T1 channels generate alarms.
• Example

  host1(config-controll)#t1 6,10-14,19 yellow generate

• Use the no version to disable generation of yellow alarms.
• See t1 yellow.
