<p>Capability is provided to dynamically reallocate the multiplex data stream from one communication channel (18) to a plurality of communication channels (26). This allows increased flexibility in responding to degradation of the main communication channel (18) and in accommodating increased user demand exceeding the capacity of the main channel. A table (42, 56) is generated to control the DTE PORTs accessed during each slot of a multiplexer frame. A separate table (44, 58) is generated to control the allocation of multiplex data between communication channels. Both tables are generated based upon a common Hash table. A plurality of Hash tables (B, C, D, E) correspond to different output data rates and permit the output rate of the multiplexer to coincide with the maximum output rate capacity of an associated transmission device such as a modem.</p> |
