US 5,444,703 A · ISDN interfacing of personal computers

Abstract

An ISDN gateway (GW) for personal computers (H) comprises at least one circuit board resident in each computer for carrying out protocol conversion and other network interface functions. To improve bandwidth of the ISDN line while transferring voice or data, a B-channel allocation algorithm executed by the gateway (GW) and the ISDN line dynamically allocates bandwidth by monitoring traffic at each destination queue and responsively allocating or deallocating virtual B-channels. Bandwidth utilization is optimized by packaging data packets into trains that are transmitted to the destination when the train is completed and upon satisfaction of other conditions. Each train undergoes data compression by execution of suitable compression algorithm.

Dependent claims

An ISDN gateway at a customer premises for interfacing a host computer to an ISDN line for communications with another host computer or with a remote local area network, comprising:

at least one circuit module resident with said host for interfacing said host to said ISDN line, said at least one circuit module including
(a) means for performing protocol conversion of data flowing between said host and ISDN line through said gateway;
(b) means for establishing input and output destination queues for said gateway;
(c) means for measuring traffic flow at each said input and output destination queues during a particular time interval;
and
(d) means responsive to said traffic flow measuring means for dynamically allocating channel bandwidth on said ISDN line.
