Page 9: Overview
The NTU is located at the customer site and acts as the slave unit. • UTU is defined by PairGain. These are programmable HDSL line units that can be configured as an LTU (master) or an NTU (slave). The UTU default configuration is NTU (slave). The UTUs do not provide line power to other HDSL units. -
Page 10: Emu Firmware Compatibility
Overview 700-712-100-01, Revision 01 EMU F IRMWARE OMPATIBILITY The EMU-830 Management Unit firmware must be Version 3.30 or later to support rate selectable HDSL units. PPLICATION NTERFACE The application interface is a synchronous serial data port with two modes of operation, Manual and Nx64k Auto. IIn the Nx64k Auto mode, the HDSL payload rate is determined by the frequency of the TT clock received at the Nx64k data port of the LTU-configured unit. -
Page 11: Hdsl Technology
HDSL T ECHNOLOGY HDSL is the core technology for PairGain’s HiGain-ETSI line of LTUs, UTUs, and ETUs. Rate selectable HDSL enables these units to transmit and receive digital data at various rates over various distances on one twisted-pair of copper wire. Both outbound and inbound signals are delivered on the same pair of wires by using echo cancellation techniques. -
