Transmitting voice frequency channels for two- and four-wire terminations using SHDSL

Передача каналов ТЧ для двух- и четырехпроводного окончания с использованием SHDSL технологии

Usage example description

Purpose: setting up a dedicated voice frequency channel for 300 – 3400 Hz signals. These signals are transmitted by means of IP technology through MR-17V8/SMR-VF modules. If SG-17E regenerators are used, it is possible to establish different alarm systems along extended trunks. From 2 to 32 VF ports in increments of 2 may be installed on a single SG-17R. Up to 8 remotely-powered regenerators may be used; for locally-powered regenerators this number is unlimited. There is also an option to transmit voice frequency channels over other interfaces of the SG-17R base platform, namely Ethernet and E1.
