Customizing the PA-T3 Serial Port Adapter

Customizing the PA-T3 Serial Port Adapter

You can customize the PA-T3 serial port adapter. The features you can customize have default values that probably suit your environment and do not require change. However, you might need to enter configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. Perform the tasks in the following sections if you need to customize the PA-T3 serial port adapter.

Setting the Bandwidth

In interface configuration mode, reduce effective bandwidth (range of 22 to 44210 kbps) by entering the dsu bandwidth configuration subcommand, as in the following example:

router(config-if)# dsu bandwidth 16000

Use the no form of this command to return to the default, which is 44210.

Note The local port configuration must match the remote port configuration. For example, if you reduce the effective bandwidth to 16000 on the local port, you must do the same on the remote port.

Defining the DSU Mode

In interface configuration mode, define the DSU interoperability mode by entering the dsu mode [0 1 2] configuration subcommand, as in the following example:

router(config-if)# dsu mode 1

Use the no form of this command to return to the default, which is 0.

Note The local port configuration must match the remote port configuration. For example, if you define the DSU interoperability mode as 1 on the local port, you must do the same on the remote port. You need to know what type of DSU is at the remote port to find out if it interoperates with the PA-T3 port adapter. For T3 serial interfaces, specify mode 0 for connection from a T3 serial port adapter to another PA-T3 serial port adapter or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-T3 serial port adapter to a Kentrox DSU. Specify mode 2 for connection from a PA-T3 serial port adapter to a Larscom DSU.

See the “Interoperability Guidelines for PA-T3 Serial Port Adapter DSUs” section on page 2-5 for information regarding DSU feature compatibilities.

Enabling T3 Scrambling

In interface configuration mode, enable T3 scrambling by entering the scramble configuration subcommand, as in the following example:

router(config-if)# scramble

Use the no form of this command to restore the default value, which is disabled.
