Telephone switch configuration detector

A telephony device for attaching to multiple different types of line cards in different types of switches, the device comprising:

• a connection for connecting to a combination of a line card and a switch;
• a monitor that detects polling information from the line card and switch combination;
• a comparator that detects a bit stream from the polling information and identifies the line card type and switch type;
• and
• a flow controller that directs the polling information to different modules if a line card type and switch type is not identified from a first set of polling information.

A telephony device for attaching to multiple different types of line cards in different types of switches, the device comprising:

• a connection for connecting to a combination of a line card and a switch providing at least two channels;
• a monitor that detects polling information from the line card and switch combination;
• a first comparator that detects bit streams from the polling information and identifies the line card type and switch type;
• a message module that generates a request for functionality supported by the switch for the connection;
• and
• a second comparator that receives responses from the switch and determines which channels of the connection support voice and which support data.

A method of detecting which of multiple different types of line cards in different types of switches a telephony device is coupled to, comprising the steps of:

• making a connection to an unidentified line card and switch combination;
• monitoring polling information received from the line card and switch combination;
• and
• comparing the polling information to expected information;
• and
• identifying the line card type and switch type based on the comparison.
