CA 2172651
Techniques are disclosed for providing interoperability between a first modem and a calling identity delivery on call waiting (CIDCW) service. According to an embodiment disclosed herein, a first modem is coupled to an alerting signal receiver and a communications re-establishment device. The alerting signal receiver receives an alerting signal generated in response to an incoming call from a third party line if the first modem is communicating with a second modem. The communications re-establishment devicereestablishes communications between the first modem and the second modem after the alerting signal receiver receives an alerting signal. The first modem is equipped to receive the alerting signal and reestablish communications with the second modem independent of the specific capabilities of the second modem, so that these techniques can be utilized in conjunction with a second modem not constructed in accordance with the embodiments disclosed herein.
