i have an NM-2ce1u module and a NM-dm30 module, i hope customer can dialin the 3660 by analog modem. i know how to use ISDN PRI q931 to configure the device to receive the dialin. but one question, the telecomm provider told me that the telecom switch is too old to provide Q.931 signaling, it can only provide CAS signnaling(R2), So i want to know whether or not the 3640 and the NM-2ce1u module can support it. without the Q.931 signaling support.
could you tell me how to configure the router? where can i find some relevant document?
