Manufacturer:ISSI Description:In off-hook Caller ID, such as CIDCW and CLIP with Call Waiting, information about a new calling party is sent to the subscriber who is already engaged in a call. Bellcores method uses CAS to alert the CPE. When the CPE detects CAS and there are no off- hook extensions, the CPE should mute its transmission path and send an acknowledgment to the end office via a DTMF digit called ACK. Upon receiving ACK, the end office will send the FSK data. Bellcore calls an off-hook capable CPE a Type 2 CPE. A Type 2 CPE is capable of off-hook and Type 1 functionalities and should ACK with a DTMF D. The ETSI and BT off-hook signalling protocols are similar to Bellcores but with timing and signal parametric differences. ETSI has no requirement for off-hook extension checking before ACK. |
