Configuring Multiservice IRIG-B Mode Port Parameters for CTP Bundles (CTP Menu)

Before you begin:

  • Disable the bundle before you modify the bundle options.

To configure Multiservice IRIG-B mode port parameters using the CTP Menu:

  1. From the CTP Main Menu, select 1) Bundle Operations.
  2. Select 1) CTP.
  3. Select a bundle from the list.

    If you select an active bundle, you are prompted to disable the bundle before configuring it.

  4. Select 3) Port Config.
  5. Select 2) Interface.
  6. Select 1) Type and set the type to Optional Interface: MultiSvc.
  7. Follow the onscreen instructions and configure the options as described in Table 6.

FieldFunctionYour Action

Mode

Specifies that the bundle will run in IRIG-B mode.

Select IRIG.

Src/Dest

Specifies the direction of the circuit. Although the IP circuit connection through the network is full duplex, an IRIG-B circuit is a simplex application, and the interface can operate only in Rx or Tx mode and not both at the same time.

(Although the bundle is by default a full duplex IP connection, you can configure it for simplex to save network bandwidth.)

Specify yes or no to the question: Is this an IRIG-B source end (IRIG-B signal enters CTP)?

  • Yes (y)—Sets direction to Rx. This end of the circuit recovers IRIG-B from the attached cable and generates IP packets toward the network.
  • No (n)—Sets the direction to Tx. This end of the circuit accepts IP packets, extracts the IRIG-B data codes, and transmits IRIG-B signaling output onto the cable.

IRIG Rate

Specifies the data rate on the IP connection.

Note the following about setting the IRIG rate:

  • Unless network bandwidth is at a premium, we do not recommend that you change this value from the default of 16,000 bps.
  • Although the IRIG information can be transported through the network at the minimum configured rate (1000 bps), a CTP bundle running at this rate is subject to high latency.

Enter a number from 1000 through 25,500 bps. The port speed must be a multiple of 100 bps.

Output High Level

This setting applies only if you set the direction of the port to Tx.

Specifies the high output level, which is measured in peak-to-peak voltage. This setting is based on a 50-ohm termination.

Enter a number from 0.00 through 7.85 volts peak-to-peak.

Output Low Level

This setting applies only if you set the direction of the port to Tx.

Specifies the low output level, which is measured in peak-to-peak voltage. This setting is based on a 50-ohm termination.

Enter a number from 0.00 through 7.85 volts peak-to-peak.
