Hi Ajay,

 

the HWIC-4T1/E1        card which u are using is used for data [high speed WAN connectivity] while the other EVM cards are used for analog voice connectivity for voice and fax which have got RJ-21 connector which could be punched on to MDF for analog DID and fax purpose.

Is it a new setup or a working ISDN line that stopped functioning? If its a new setup (attach your sh run along the post) if not post the output of sh controller e1.
