Chapter 1. Overview
This chapter begins with a general description of Comet 16xx Series. Then, the
chapter describes how to use TAINET Comet 16xx Series in several applications.
1.1 Overview
DSL (Digital Subscriber Loop) technologies increase the bandwidth capacity
of existing ubiquitous telephone line (the local copper loops). G.SHDSL is
designed for business applications, where high speed is required in both
transmission directions. It provides symmetrical data rates of 192Kbps to
5.696Mbps in 2-wire with a transmission distance up to 10Kft using SHDSL
technology. The data rates will be increased to 11.392Mbps in 4-wire link and
22.784Mbps in 8-wire link. The speed’s obtainable using DSL technologies
are tied to the distance between the customer premise and the Telco central
office. Performance varies with loop characteristics, such as line conditions,
loop distance, wire gauge, noise, and the number and locations of bridged
taps and gauge changes. The G.SHDSL bit rate can be configured (or rate
adapted) to adapt to the line conditions.
1.2 Applications
The SHDSL System consists of a central unit, CO (SHDSL Transceiver Unit -
Central), at central office, and a remote unit, CPE (SHDSL Transceiver Unit -
Remote), at customer premises.
The services are extended through the ubiquitous copper wires or leased
lines with the technologies of G.SHDSL. Various interface extensions are
supported on Comet: E1, DATA (V.35, V.36 / RS449, X.21, RS-530) and
Ethernet.
Figure 1-1 shows a typical application. Figure 1-2 depicts the possible
interface configurations. Comet automatically activates start-up when the

power of the CO and CPE are enabled or after temporarily disconnecting the
CO or CPE.
