There is a command on my AS5300 which I don't understand. It is

[admin_2]

I am looking for an explanation for the command "ISDN T203 10000" on an AS5300. It was part of an ISDN d channel configuration.

Yes, the command is not documented;

I think that is partly due to the fact

that it wasn't usually configurable.

From the Q.921 spec:

Timer T203 represents the maximum time

allowed without frames being exchanged.

The default value of timer T203 shall be

10 seconds.

For the most part, you should not change

this value.
