SHDSL 2300 Concentrator
|
The 2300 SHDSL Concentrator family provides enterprises or operators with a very
high-density SHDSL transmission solution at the central office or in concentrator sites.
It is possible to use variable bit rates as well as dual pair operation to extend the reach
of the transmission over longer distances. Data is delivered over G.703/G.704 interfaces and both transparent and
fractional operation is supported. In case of service delivery at speeds lower than 2 Mbps, grooming (concentration)
of different users on a single E1 circuit can be provided. The dedicated 2300 concentrator with remote powering can
be used to power repeaters or network termination equipment. The unit is designed for integration into demanding
network environments and can be directly controlled by the complete set of network maintenance and management tools
as they are described in the section on network management. For management purposes the concentrator features a
direct 10/100Base-T connection for IP, a local console interface, and a dual G.703/G.704 interface with add-and drop
functionality. Typical applications in a carrier environment include the provisioning of high-quality data services
like leased lines or Frame-Relay and the concentration of multiple circuits interconnecting base-stations of a mobile
operator. Enterprises or organisations with own copper infrastructure can use this type of equipment to meet their own
communication requirements without having to invest in a new transmission infrastructure.
