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
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
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.
