Telecommunication system protocol for asynchronous data communication between multiport switch control processor and information support personal computer terminal
First Claim
1. In a telecommunication system with a multiport switch controlled by central processing unit to interconnect telephone calls received from telephone units of an external network with an internal network of agent telephonic units connected with the multiport switch and in which the central processing unit communicates data with an information support computer terminal on a single, asynchronous, data communications link, a communication protocol method for communicating on said communication link, comprising the steps of:
- establishing a multilayered compressed OSI Model Protocol in which the functions of the OSI Model protocol layers respectively entitled Data Link, Network, Transport and Session are combined into a single protocol layer; and
communicating on said asynchronous communication link in accordance with the multilayered compressed protocol.

Abstract
A telecommunication system (40) with a multiport switch (42) controlled by a central processing unit (44) to interconnect telephone units (48) of an external telephonic network (50) with an internal network of agent telephonic units (52) connected with the multiport switch (42) and to communicate with an information support computer terminal (56) on a single, asynchronous, data communications link (58), a communication protocol method for communicating on the communications link (58) having the steps of establishing a multilayered compressed protocol in which the Data Link (24), Transport (28) and Session (30) layers of the OSI model (20) are combined into a single protocol layer (62), transmitting the compressed protocol on the asynchronous communication link (58), and transmitting a frame of information between the IST (56) and the telecommunication system (40), the frame having a plurality of different fields respectively associated with different types of information arranged in a preselected frame form including a frame type field (80), a channel identification field (82) including a destination channel for which the message is conveyed, a last message data identification field (96) for indicating the last message identification received, a frame sequence field (98) indicating the portion of the frame being transmitted in a sequence of frames which comprise the message identified, a message identification field (94) for identifying the message with which the frame being transmitted is associated, a size field (105) indicating the size of the data field (108), and a frame check sequence field (110) indicating information to check for accurate receipt of the message.
