Auctully I could not install my ISDN modem on my Cisco 2621 Router for incomming ISDN connection on serial interface.

Could it be possible to install ISDN Modem on serial interface of router for incomming connection.

Auctully I could not find any related document for intalling TA on Router's Serial interface.

Thanks in Advance.

Attaching an ISDN TA to a serial interface should work fine. You may want to confirm the control lead settings of the TA, however. Look here for some info:

The config can be just a vanilla DDR config:
