router crash

[kapishmohole.cisco]

Hello to all,

Is there any chance of router geting crashed because of misconfiguration, especialy physical parameter misconfiguration- line code, deplex etc.

I am going to configure an access server, we want to use the 24 -digital modem module on 2620 router with T1 circuit. I want to know, does this digital modem module supports both digital calls - ISDN and analog calls - PSTN?

Though there should not be any crash due to misconfiguration, it might sometime depend on the particular release. Tthe following document is related to AS5300, but I guess you can use it for a 2600 to configure a T1 interface for both analog and ISDN calls.
