High-speed digital subscriber line solution can now be easily implemented

9 May 2001 Telecoms, Datacoms, Wireless, IoT

Schmid Telecommunication is a global player in high-speed digital subscriber line (xDSL) access network solutions and integrated voice communications systems (ICS) for air traffic and command and control centres. Serving customers globally through a network of offices, partner companies and distributors (Channels Measurement Services in southern Africa), its products include Watson, a versatile xDSL family.

The company's innovative DSL products can help deliver high speed services using the telco's existing copper network. Carriers and service providers focus on market coverage, rapid deployment and cost-efficiency. The Watson family is an xDSL platform that offers clear advantages over other high speed access technologies. It can be installed quickly and easily, and at very low cost in a matter of hours. The products are as follows:

Watson 2 HDSL

Within the telco environment, Watson 2 HDSL can be used for lucrative applications as: adding Nx64 Kbps to full 2 Mbps leased line services; primary rate ISDN; concentrating more subscribers on the same cable; replace maintenance-intensive HDB3 repeater link.

Watson 2 HDSL equipment is specially designed for large telco deployments, where cost-effectiveness, performance and quality are absolutely mandatory success factors.

Watson 3 HDSL

In addition to its telco applications, Watson 3 HDSL systems are the ideal solution wherever dispersed sites need to be connected. In campus area networks, such as those found in corporate, hospital, university and military base settings Watson 3 can be used to: enable mobile base station interconnection along railways, power lines and highways; deliver high speed Internet and ATM access; extend and connect LAN and PBX networks; connect traditional copper loops to a fibre-optic backbone.

It is the performance of the Watson 3 family member, that makes it the choice for demanding copper plants. Based on CAP HDSL technology, Watson 3 goes up to 25% further compared to conventional xDSL equipment. Watson 3 allows one to inexpensively install high quality repeaterless E1 trunks over distances of up to 10 km. In most cases, this eliminates the need for regenerators in the access network. However, for very extreme cases, Watson 3 interconnections can be built with a regenerator, or even consist of several cascaded DSL links, which extends its reach to more than a hundred kilometres.

Watson 4 MultiSpeed

Watson 4 MultiSpeed is the ideal solution for single pair copper transmission to private homes or small home offices at variable bitrate. Telcos and service providers, as well as campus operators can use the cost-effective MultiSpeed technology to: deliver and concentrate high speed Internet services; replace existing costly leased lines; provide high speed IP/FR/ATM access; interconnect PBX and data networks on a single link.

Watson 4 MultiSpeed provides stable connections, making it the choice for providers who want to roll out services quickly without having to worry about the copper plant. A true 'one device fits all' solution, keeping logistic and provisioning costs down from the start. It features 'Multipoint' functionality on high density LTUs. Up to four links can be concentrated into a single E1 interface, reducing overall system cost. In campus applications, the 'Multiservice' functionality allows the interconnection of a PBX (fractional E1) and a data network (N x 64K) using a single device, thus avoiding the need for a service multiplexer.

Multiservice functionality

Perfect for campus applications and enterprise networks Watson FO Telcos and new carriers are constantly modernising their access networks, which creates the demand for a versatile access platform like Watson. Watson FO is the fibre-optic extension to Schmid Telecom's xDSL platform. Watson FO is the solution for: hybrid access networks; very remote locations; interconnection of mobile telephony base stations; interconnections in high voltage environments.

Regenerator

The regenerator is designed for the regeneration of two pairs (1168 Kbps each). Schmid Telecom offers several repeater housings (1, 2 or 4 links) for outdoor and indoor applications. The regenerator features remote monitoring and powering, loop setting and CRC-6 regeneration.
