ABSTRACT:
A telecommunications apparatus is disclosed for use in conjunction with a local switch. The apparatus operates in a bypass mode for messages that do not require compression/decompression, and in a pass-through mode for those which do. A selective compressor/decompressor is provided to decompress incoming information for which the local switch is to operate in pass through mode and to compress outgoing information for which the local switch has operated in pass through mode. A selective masker/demasker is operative to expand information to be bypassed by the switch without decompressing the information from a compressed form to an expanded form and to restore information bypassed by the switch from the expanded form to the compressed form.
