Analog Devices and Texas Instruments will introduce chips for DSL modems later this year, while AMD and Virata say they are working on designs for asymmetric digital subscriber line (ADSL) modem chip sets.
Texas Instruments (TI) is opening a DSL (digital subscriber line) modem factory in Bejing, China, with Legend Group - the country's largest PC maker. The two companies will work together on a DSL consumer modem based on TI's DSL chips.
A V.90 modem operates at a theoretical maximum of 56Kbps downstream, while ADSL Lite and full ADSL promise speeds of up to 1.5Mbps and 8Mbps respectively. Lucent Technologies has unveiled a chip set which combines V.90, ADSL Lite and full ADSL...
ADSL is more suitable for residential users and small businesses as they would mostly use it for downstream access, that's to say downloading from the internet, but having upstream speed requirements of much less than 2Mbps," Johnson explains.
If the 'null' password isn't changed, a hacker can gain access to the modem, either disabling it or altering the software with a 'Trojan horse'. A sniffer spies on all data passing through the modem. Responding to the reports, Alcatel released a...
Earlier this month, the telco said "symmetric broadband is ideal for business use as it supports applications that require the same upstream and downstream speeds. A BT spokeswoman confirmed on Friday that it has stopped upgrading local exchanges...
