Abstract
Dynamic channel allocation in an ISDN line is implemented above a Level II link layer protocol (LAPD). The preferred embodiment comprises programming operating on a computing platform system including a communication coprocessor system. The programming includes a channel management module (CMM) and a virtual channel module (VCM) to implement dynamic channel Allocation. The modules cooperate to control bandwidth between communication partners by selective allocation and deallocation of virtual B-Channels between them in response to preassigned priorities and real time events. Voice and data channels are interrogated. Channel deallocation also takes place in response to high error rates in message transmission.
