Setting the Serial Interface Type and Rate
The 4804 Management Module has a DB25 interface (labeled V.35/X.21) that can
be defined as V.35 (the default), EIA-530-A, or X.21. If you intend to use the
connector for a V.35 or X.21 uplink, you must change the software setting.
The V.35/X.21 port has a default rate of 2048 Kbps. You must change the setting if
the interface is configured for internal clocking and you require a different rate.
Procedure
To set the serial interface type and rate for the V.35/X.21 uplink port:
1. At the
IAC#
prompt, type:
configure interface v35 type
interface_type
Where:
— interface_type is the type of interface required by the device connected to
the V.35/X.21 uplink port. It must be one of:
— eia530a
— v35
— x21
For example:
conf int v35 typ x
2. Press Enter. The prompt changes to
IAC#!
to show that the configuration
change has yet to be saved.
3. At the
IAC#!
prompt, type:
configure interface v35 rate
data_rate
Where:
— data_rate is the rate in Kbps. It must be a multiple of 8 between 64 and
8192.
For example:
conf int v35 ra 1536
4. Type
save
and press Enter.
5. To verify that the type and rate have been set, type:
show int v35 conf
The CLI displays all configuration options for the V.35/X.21 uplink port,
including the type and rate.
