Patent ID: 6901077

Claim:
A method of exchanging information between at least some slots of a first T-carrier and some other non-coincidental slots of a second T-carrier, such method comprising the steps of: exchanging information between successive slots of the first T-carrier and respective predetermined memory locations within a memory device; exchanging information between successive slots of the second T-carrier and at least some of the predetermined locations in memory of the first T-carrier based upon address data for the exchanged information provided within a channel-exchange list that relates at least some channels of the first T-carrier to at least some other channels of the second T-carrier; determining whether the exchanged information in each successive slot should be compressed or decompressed based upon a status of specific bit locations of the respective address data for the exchanged information; and when required, compressing or decompressing the information from successive slots of the first T-carrier, wherein the step of determining whether the exchanged information should be compressed or decompressed further comprises compressing and saving the information under both compressed and uncompressed formats and selecting one of the compressed and uncompressed formats based upon the status of the specific bit locations, and wherein the step of determining whether the exchanged data should be decompressed further comprises decompressing the information and overwriting corresponding predetermined memory locations with the decompressed information when the status of the specific bit locations indicate that the corresponding predetermined memory locations contain compressed data.
