TLDR
An ATM call interworking with the public switched telephone network may experience echo problems due to impedance mismatch, so two echo control designs are proposed to assure the quality of voice services by reducing round-trip echo delay.Abstract:
An ATM call interworking with the public switched telephone network may experience echo problems due to impedance mismatch. The authors propose two echo control designs to assure the quality of voice services by reducing round-trip echo delay. Performance of these two echo control designs is then analyzed. >read more

Multiplexing of voice and data minicells
TL;DR: In this article, a transmission priority code is assigned to each segmented user data packet based on the type of data contained therein in a telecommunication system that employs asynchronous transfer mode.
Patent
Transmission of voice over an asynchronous network
TL;DR: In this paper, the authors propose a constant bit rate segmentation and reassembly (CBR SAR) circuit, which aggregates the voice data into an appropriate number of ATM cell slots for each of those channels.
Patent
Digital communications system
TL;DR: In this article, a network arrangement for transporting service (Servco) traffic between terminals via an asynchronous path comprises a Servco access layer incorporating multimedia gateways for access by said terminals, an asynchronous network layer, a service layer incorporating adaptation layer switches each coupled to the network layer.

Method and apparatus for synchronizing a data communication system to a periodic digital impairment
TL;DR: In this paper, a modem system is configured such that signal segments are formatted and transmitted with six symbols per segment, and the second modem initializes a modulo-6 symbol counter such that the zero count corresponds to the first symbol of each received signal segment.
Patent
Simultaneous transmission of voice and non-voice data on a single narrowband connection
TL;DR: In this article, a method and a system for simultaneously and independently multiplexing voice and non-voice data over a single, commonly shared PSTN access line is proposed, which is accomplished by packetizing the voice and NV data into minicells, and then multiple-xing the miniclouds into a single data stream for transportation across the common access line.

Broadband ISDN and asynchronous transfer mode (ATM)
TL;DR: The transfer mode chosen by the CCITT Study Group XVIII Task Group on ISDN Broadband Aspects as the basis of broadband ISDN is called the asynchronous transfer mode (ATM), a high-bandwidth, low-delay, packetlike switching and multiplexing technique.

Broad-band ATM network architecture based on virtual paths
TL;DR: The virtual path concept, which exploits the ATM's capabilities, is proposed to construct an efficient and economic network to provide efficiently for networks with dynamic reconfiguration capability which will enhance network performance.

Voice packetization and compression in broadband ATM networks
TL;DR: Some methods of supporting voice in broadband ISDN, (B-ISDN) asynchronous transfer mode (ATM), including voice compression, are examined and possible approaches for packetization and implementation of variable-bit-rate voice coding schemes are described.

Models for the subjective effects of loss, noise, and talker echo on telephone connections
TL;DR: These subjective test results are used to formulate graphical and analytical models of subjective opinion that can be used in network planning studies to evaluate transmission performance of the network and to study the effects of network changes on performance.
