HDSL

Teansmission of high-speed data over copper wire

OT HDSL system maximize thr transmission efficiency effiency by tramsmitting the high speed T1(1.544Mbps)/E1(2.048Mbps) and N*56/64Kbps data over existing copper wire.

Long distance transmission without repeater

OT's HDSL can guarantee excellent transmission quality while its transmission coverage is up to 4.0km without repeart at 26AWG copper wire.

Transmission of the varoous signals

OT HDSL can transmit the extensive range of signals such as. Telephone, PC data, viedo signal. N*56/64kbps and Full T1(E1) data.

Performance monitoring

The performance monitoring of system and operation can be dislpayed on the front LCD. when the network is configured as the Stand-alonetype HDSL. - COT, RT set-up - Display of S/N Margin - N*56/64kbps set-up - Control of RT unit - Detection of FEBE, NEBE per Loop 1&2 - Detection of BPV/s

Integrated maintenance and administration and extensive NMS function

The COT (central Office Site) can monitor the RT(RemoteSite) so systematic and integrated OA & M are guaranteed. - PC-based NMS enviironmet - Graphic User Interface(GUI) provides the convenient OA&M function - Local office's integrated management and control of of the remotely localed equipment - Modification of the Local/Remote configuration - Continuous monitoring of the signal and alarm indication when fault occurs - System test on Local/Remote loopback function - Performance monitoring

Remote power feeding

The LPU Provides the power to the remote site according to the operator's selection.
