SHDSL (single pair high-bit-rate digital subscriber line) technology will be aimed at small and medium sized businesses and will carry symmetrical two-way data traffic at speeds of up to 2.3mbps.
It will offer security, standards-based management and transmission across greater distances than currently available ADSL services. SHDSL can be transmitted across distances of more than 20,000 feet from the local exchange, while ADSL is restricted to about 5,000 feet - which effectively bars many would-be subscribers from the service.
Efficient Networks last week released an SHDSL device, the 5950 Business Gateway. It is designed for installation at customer sites and offers eight ports of 10/100mbps Ethernet.
