Transparent call discrimination (TCD) method and apparatus
First Claim
1. A method of transparent call discrimination comprising the steps of:
- providing a call discrimination data message within a Caller ID message frame structure of an outgoing call from a call originating equipment, said Caller ID message frame structure having a single data message frame format, the single data message frame format characterized by a channel seizure frame, a mark signal frame, a message type frame, a first mark bits frame, a message length frame, a second mark bits frame, a message word frame, a more message word frame, a third mark bits frame, and a checksum frame;
discriminating a type of call on an incoming telephone line of a call receiving equipment in response to the call discrimination message, wherein the type of call is discriminated prior to an occurrence of an OFF-HOOK state of the telephone line;
activating an appropriate device of the call receiving equipment in response to the type of call in preparation for responding to the incoming call; and
routing the incoming call to the appropriate device in response to the discriminated type of call at the occurrence of the OFF-HOOK state.

Abstract
A method of transparent call discrimination includes providing a call discrimination data message within a Caller ID message frame structure of an outgoing call from a call originating equipment. A type of call on an incoming telephone line of a call receiving equipment is discriminated in response to the call discrimination message, wherein the type of call is discriminated prior to an occurrence of an OFF-HOOK state of the telephone line. An appropriate device of the call receiving equipment is then activated in response to the type of call, in preparation for responding to the incoming call. Lastly, the incoming call is routed to the appropriate device in response to the discriminated type of call at the occurrence of the OFF-HOOK state. An apparatus for transparent call discrimination is also disclosed.
