This is achieved by coordinating the sending, receiving, and acknowledging (i.e., handshaking) of muting control signals within a cordless link between a designated master telephone unit and designated slave telephone extensions.
FIG. 1 depicts a block diagram of the �handshaking� required in order to implement the Type II CID feature. First, an initial telephone call between the subscriber 10 and a second party 11 is already in progress. As is known in the art, the call between subscriber 10 and the second party 11 is routed through a central office (CO) 13 via communication links 20 and 21. The subscriber 10 actually receives the call on subscriber line 35 through telephone line 37. Next, a third party 12 seeks to place a telephone call directly to the subscriber 10, however, the third party's 12 call must first be routed through the CO 13, via communication link 14. Next, the CO 13 sends two signals 15 (a subscriber alerting signal (SAS) and a CPE alerting signal (CAS)) to the subscriber 10, alerting the subscriber of the incoming telephone call from the third party 12. The subscriber's 10 telephone unit then sends an acknowledgement signal 16 back to the CO 13, alerting the CO that it is ready to accept the Type II CID data 17. The CO then sends the data 17 to the subscriber 10, where it is displayed and whereby the subscriber may make an informed decision as to whether the call between him or herself 10 and the second party 11 should be interrupted in favor of the call from third party 12.
If the CPE 10 is the only telephone currently off-hook, the CPE 10 will then mute the CPE handset at step S8 in preparation for sending acknowledgment signals back to the CO 13, thereby alerting the CO 13 that it is prepared to receive the CID data 17. The acknowledgement signals are sent to the CO 13 at step S9 in dual tone multi frequency (DTMF) format (i.e., �touch tone�). Upon receipt of the DTMF acknowledgement signal 16 at step S10, the CO 13, in turn, forwards the CID data 17 to the CPE 10 at step S11, whereby the subscriber may then make an informed decision as to whether the call that is already in progress should be interrupted in favor of the incoming call from the third party.
SUMMARY OF THE INVENTION The present invention overcomes the problems associated with the prior art and provides a method and system for receiving Type II CID data in an environment containing multiple off-hook cordless telephones, all being fitted for receiving CID data, and all being coupled to a common subscriber line. This is achieved by coordinating the sending, receiving, and acknowledging (i.e., handshaking) of control signals between the multiple cordless telephones and the CO. In a preferred embodiment of the invention, the communication between cordless telephones takes place through a wireless connection between each off-hook slave extension and a master unit.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described with reference to FIGS. 3-6. Other embodiments may be realized and structural, or logical changes may be made to and equivalents used for elements of the disclosed embodiment without departing from the spirit or scope of the present invention.
