Cisco Systems PA-2E3, PA-E3 Setting the Bandwidth, Defining the DSU Mode, Defining Set Bit National

Setting the Bandwidth

Setting the Bandwidth

In interface configuration mode, reduce effective bandwidth (range of 22 to 34010 kilobits per second) 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, 34010.

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] 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, 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-E3. For E3 serial interfaces, specify mode 0 for connection from a PA-E3 to another PA-E3 or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-E3 to a Kentrox DSU.

Also refer to the “Interoperability Guidelines for PA-E3 DSUs” section on page 15 for information regarding DSU feature compatibilities.

Defining Set Bit (National)

In interface configuration mode, define set bit in G751 frame (national bit) by entering the national bit [0 1] configuration subcommand, as in the following example:

router(config-if)# national bit 1

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

Enabling E3 Scrambling

In interface configuration mode, enable E3 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.

Note The local port configuration must match the remote port configuration. For example, if you enable scrambling on the local port, you must do the same on the remote port.

Also refer to the “Interoperability Guidelines for PA-E3 DSUs” section on page 15 for information regarding DSU feature compatibilities.
