High-Speed Voice and Data Link 3.1 Extended Reach DSL System


HVDL Extended Reach DSL System

 
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. 


1RU HVDL Shelf


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 features include:

  • CLASS services compatible
  • NEBS compliant (GR-63-CORE, GR-1089-CORE)  
  • RDUP Listed
  • No desktop modem required

Unique Advantages

  • Supports line powered repeater: reach up to 56,000 ft.

  • Reach can be extended to 112,000 feet with local power RT

  • Spectral compatibility with ADSL

  • Line powered RT provides Lifeline Service on all voice lines

  • Enhanced lightning protection

  • Rate selectivity (data rate adjustable in 128 Kbps increments at the COT) for tiered service revenues 


Applications

  • Deliver DSL to remote or extended reach customers

  • Provision cost-effective DSL in areas of low subscriber density

  • Deliver multiple voice and data lines for SOHO environment
