Abstract
Abstract An arrangement for interfacing between TDM and ATM networks consists of a family of devices that comprises two groups. The first group comprises devices that perform multiplexing, segregation and routing field translation for the respective traffic type. They may also remove or substitute an outermost layer of encapsulation. These first group devices are bi-directional and output buffered with respect to the network. The second device group comprises devices that perform format conversions between the service payload (voice, video or data) and an adaptation layer control format. These second group devices are also bi-directional and buffering depends on the particular function, e.g. real-time, segmentation.

Claim 2
Dependent Claim
56 words
An ATM adaptation interface for processing a plurality of traffic types, said interface comprising a first group of devices that perform multiplexing, segregation and routing field translation for each said respective traffic type, and a second group of devices that perform format conversions between service payloads of said traffic types and an adaptation layer control format.
Claim 3
Dependent Claim
80 words
An ATM adaptation interface for processing a plurality of traffic types, said interface comprising a first group of devices that perform multiplexing, segregation and routing field translation for the respective traffic type, a second group of devices that perform format conversions between service payloads comprising voice and data and an adaptation layer control format, and an interface disposed between said first and second devices of the two groups for the transference of arbitrary and variable length packets between said devices.
Claim 4
Dependent Claim
80 words
An ATM adaptation interface for processing a plurality of traffic types, said interface comprising a first group of devices that perform multiplexing, segregation and routing field translation for the respective traffic type, a second group of devices that perform format conversions between service payloads comprising voice and data and an adaptation layer control format, and an interface disposed between said first and second devices of the two groups for the transference of arbitrary and variable length packets between said devices.
Claim 5
Dependent Claim
69 words
