ISDN interfacing of local area networks

An ISDN gateway at a customer premises for interfacing a local area network having at least one host to an ISDN line, comprising:

• at least one circuit module resident with said host for interfacing said local area network to said ISDN line, said at least one circuit module including
• (a) means for performing protocol conversion of data flowing between said local area network and said 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 of said input and output destination queues during a particular time interval;
• (d) means responsive to said traffic flow measuring means for dynamically allocating channel bandwidth on said ISDN line;
• wherein said means for dynamically allocating includes long term channel allocation means responsive to a polling means for allocating or deallocating transmission channels to a particular destination on said line depending upon data flow traffic to said destination and particular channel parameters;
• and
• short term channel allocation means, overriding said long term channel allocation means in response to predetermined conditions, for allocating or deallocating transmission channels on said line.

An ISDN gateway system at a customer premises for interfacing a remote host to a local area network via an ISDN line, comprising:

• at least a first gateway module resident with said remote host for connecting said remote host to said ISDN line,
• at least a second gateway module resident with said local area network for interfacing said local area network to said ISDN line,
• each of said first and second gateway modules including
• (a) means for performing protocol conversion of data flowing between said remote host or said local area network and said ISDN line through said gateway modules;
• (b) means for establishing input and output destination queues for said gateway system;
• (c) means for measuring traffic flow at each of 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.
