Customizing the PA-E3
Customizing the PA-E3
Depending on the requirements for your system configuration and the protocols you plan to route on the
interface, you might need to enter configuration commands to customize the
PA-E3.
Most of the features
you can customize have default values that will probably suit your environment and need not be changed.
However, if you need to customize your configuration, see the following sections:
•
Setting the Bandwidth, page 4-11
•
Defining the DSU Mode, page 4-11
•
Defining Set Bit (National), page 4-12
•
Enabling E3 Scrambling, page 4-12
•
Specifying E3 Framing, page 4-12
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 1-20
section for
information regarding DSU feature compatibilities.
