Leased Line Extension over Copper

Carriers and service providers can gain revenue streams by using SHDSL technology to extend leased line services to more customers where fiber is not available.

DSL technology uses ordinary telephone lines to deliver voice and broadband services such as high speed data, Internet access and videoconferencing. It turns existing copper wire into a high capacity pipeline. Carriers and service providers can diversify services by bundling voice and data over the same copper pair, with rapid deployment and simple provisioning. Incumbent carriers don’t need to lay new cable, and new carriers can lease fewer lines from the incumbent. DSL’s ability to deliver converged services with lower operating costs (Opex) opens up new business opportunities and a faster payback of capital expenses (Capex).

 

SHDSL fulfills the broadband requirements of business users for symmetrical, two-way traffic. SHDSL extends transmissions farther than any other DSL technology, enabling service providers to deliver low cost, multiservice, broadband access to a wider subscriber base.

Carriers and service providers, and even enterprises, can improve bandwidth utilization, save space and simplify operation using RAD’s DXC multiservice access node at a central site to groom up to 96 smaller links from individual customers or offices into large pipes to the SDH/SONET network. DXC also reduces the number of required ports on the SDH/SONET add-drop multiplexer (ADM). All services, such as ISDN U, IDSL, E1/T1, E3/T3, n x 56/64 kbps, LAN and Frame Relay, are provided alongside the DSL services and are managed on the same platform.

The ASMi-52 SHDSL multiplexer modem extends the range of digital interfaces to up to 9 km (4.7 miles), at variable data rates from 64 kbps to 2.3 Mbps over 2-wire. Equipped with an Ethernet and E1/T1 or serial port (V.35 or X.21), the ASMi-52 can provide dual services at the remote site and save the investment in an additional modem.

 

The attractively priced ASMi-52L modem offers four Ethernet ports with an integrated switch for Ethernet connectivity to the DXC multiservice access node.

 

Repeaters can be used to extend the SHDSL line, increasing the coverage to additional remote sites.
