FEATURES
SPECIFICATIONS
Using HDSL technology, the HCD-4 operates at rates of n x 64 kbps up to 4
Mbps over 4-wire lines.
The HCD-4 extends the transmission range up to 3 km (1.9 miles) over 24 AWG
(0.5 mm) 4-wire copper cable.
HCD-4 compensates for line impairments, bridge taps and mixed cabling by
using advanced equalization, adaptive filtering, echo cancellation
technology and 2B1Q line coding. High immunity to background noise enables
transmission of multiple HDSL lines via the same physical cable.
Setup, control and monitoring of status and diagnostic information can be
performed using one of the following:
- front panel LCD with three pushbuttons, using menu-driven management
- ASCII terminal connected to the async control port using command line
interpreter
Supporting a built-in Ethernet bridge or built-in IP router, the HCD-4
provides a cost-effective and easy-to-install solution for LAN-to-LAN
applications. The HCD-4 supports V.35 and RS-530, enabling connection of
digital equipment at 4 Mbps for corporate applications.
HCD-4 is available as a standalone unit or can be mounted in a standard 19"
rack using special hardware. Two HCD-4 units can be mounted side-by-side.
