Communication system having automatic circuit board initialization capability

Claim 2

A communication system comprising a controller connected to one or more port circuits for providing communications between trunks and lines connected to said one or more port circuits, said system further comprising: feature defining means at each of said port circuits for storing operating parameters defining a plurality of features which can be performed thereat, and reporting means at each of said port circuits responsive to a predetermined status condition therat for reporting its identification type code to said controller and said controller including memory means for storing predetermined operating parameters defining one of said plurality of features to be performed at each type of said port circuits connected to said system and means connected to said memory means and responsive to the receipt of said type code from each reporting port circuit for accessing said memory means using said type code and for sending predetermined operating parameters to said each reporting port circuit thereby defining one of said plurality of features to be performed therat.

Claim 3

The communication system of claim 1 wherein said predetermined status condition is responsive to a rest signal from said controller.

Claim 4

The communication system of claim 1 wherein said predetermined status condition results from the applicaiton of power to said system and said predetermined operating parameters for each of said one or more port circuits are default options.

Claim 5

The communication system of claim 1 wherein said reporting port circuit is inserted in said system replacing a port circuit of the same type which was removed from said system, the replacement occurring while said system is powered and wherein said predetermined status condition is responsive to power being applied to said reporting port circuit when said reporting port circuit is inserted in said system and wherein said predetermined operating parameters sent to said reporting port circuit are the operating parameters of the replaced port circuits.

Claim 6

The communication system of claim 1 wherein said controller further comprises means responsive to said reporting port circuit for outputting an error signal when the received port circuit identification type code is not one which is stored in said memory means.

Claim 7

The communication system of claim 1 wherein said controller further comprises means responsive to a signal received from said reporting port circuit for preventing the sending of said operating parameters to said reporting port circuit when the number of said one or more port circuits of that type execeed a predetermined number in said system.

Claim 8

The communicaiton system of claim 1 including an equipment housing having a plurality of board slots and wherein each of said one or more port circuits being adapted to be plugged into any of said plurality of board slots in any order.

Claim 9

The communication system of claim 4 wherein said predetermined status condition is responsive to a reset signal form said controller.

Claim 10

A port circuit initialization arrangement for use in a communication system comprising a controller connected to one or more port circuits for providing communications between trunks and lines connected to said one or more port circuits, said port circuit initialization arrangement comprising feature defining means at each of said port circuits for storing operating parameters defining a plurality of features which can be performed thereat, and reporting means at each of said port circuits responsive to a predetermined status condition thereat for reporting its identification type code to said controller and memory means in said controller for storing predetermined operating parameters defining one of said plurality of features to be performed at each type of said port circuits connected to said system and means in said controller connected to said memory means in said controller connected to said memory means and responsive to the receipt of said type code from each reporting port circuit for accessing said memory means using said type code and for sending predetermined operating parameters to each reporting circuits thereby defining one of said plurality of features to be performed thereat.

Claim 11

A port circuit initialization arrangement for use in a communication system comprising a controller connected to one or more port circuits for providing communications between trunks and lines connected to said one or more port circuits, said port circuit initialization arrangement comprising feature defining means at each of said port circuits for storing operating parameters defining a plurality of features which can be performed thereat, and reporting means at each of said port circuits responsive to a predetermined status condition thereat for reporting its identification type code to said controller and memory means in said controller for storing predetermined operating parameters defining one of said plurality of features to be performed at each type of said port circuits connected to said system and means in said controller connected to said memory means in said controller connected to said memory means and responsive to the receipt of said type code from each reporting port circuit for accessing said memory means using said type code and for sending predetermined operating parameters to each reporting circuits thereby defining one of said plurality of features to be performed thereat.
