HVDL High-Speed Voice and Data Link 3.1 Extended Reach DSL
Unlock the High-Speed Potential of Copper
The Charles’ High-Speed Voice & Data Link (HVDL) enables a single copper pair to
deliver three voice channels and one high-speed Ethernet data channel to
small business and residential subscribers, both urban and rural.
Utilizing low-noise, low-power TCPAM (G.shdsl) line coding, the system
multiplexes three 64 Kbps Clear channel voice lines and one high-speed
data line for transport, then demultiplexes at the subscriber’s Remote
Terminal (RT). The system, which supports advanced CLASS services,
consists of a Central Office Terminal (COT) line card, shelf, RT and optional
repeaters. The RT and repeaters are line powered.
Local Power RT Increases Reach Even More
With this device, HVDL can deliver 1 Mbps up to 80,000 feet or 128
Kbps to 112,000 feet. With this reach, HVDL truly enables ubiquitous
deployment of DSL throughout the entire subscriber base.
1RU Solution
A one rack unit (1RU) shelf option provides up to three HVDL lines. This
"pizza box" solution is ideal for installations in
outdoor/remote cabinets.
More Than Just a Remote DSL Solution
While HVDL is an excellent solution for rural and remote locations, it
also offers a prime opportunity for carriers to add new and upgraded
services for urban customers. By offering additional voice and fax lines,
urban SOHO customers are provided a sought-after solution: three voice/fax
lines and one high-speed data line all on a single twisted pair. Key
