NASHUA, NH–( EMWNews – April 2, 2008) – Semaphore, a CSE Global company, announces availability

of the S20 SHDSL Modem, which provides dual Ethernet transmission at high

speeds over copper wire pairs. The new modem enables conversion of an

existing copper wire infrastructure into a high-speed Ethernet network when

installing a new SCADA or

telemetry system, even if it spans distances previously unattainable by

conventional DSL technology

The Semaphore S20 SHDSL Modem extends

communication speed and reach without the additional investment of

installing new communications media. An alternative to wireless

technology, the S20 SHDSL Modem’s unique repeater capability enables

communications over existing copper wire networks spanning up to hundreds

of kilometers. The modem is ideal for railway, pipeline, utility and power

transmission applications that presently employ copper wire communications

networks.

The S20 uses G.SHDSL (Symmetric High-bit rate Digital Subscriber Loop)

technology for sending and receiving high-speed symmetrical data streams

over a single pair of copper wires at rates between 192 kbps to 2.31 mbps.

Also known as G.991.2, G.SHDSL is an international standard for symmetric

DSL developed by the ITU.

Semaphore’s implementation is a rugged design that is suitable for

industrial applications, which require operation over a wide temperature

range. The S20 provides transparent Ethernet connectivity and supports any

standard, IP messaging such as Modbus TCP. Symmetric communication also

allows video and voice transmission.

Configuration of the S20 is extremely simple and uses a web interface to

display DSL and Ethernet port status and configure line speeds, network

address, and authentication permissions.

Semaphore’s connectivity products are ideal for a broad range of monitoring

and control applications in the broadcast, infrastructure management, oil &

gas, power, transportation and water treatment and distribution industries.
