[Issue II]
Hi Again,
Oh, THAT Issue II! From a May 12 posting by Tom Doughty (Reply #17444) I've refreshed my memory. Permit a partial posting please..........
This week, the ANSI T1E1.4 working group is finalizing Issue II of the ADSL specification. Most of the work for Issue II is focused in the following areas:
-- Backwards compatibility with Issue I of ANSI T1.413
-- Clarifications to Issue I text for multi-vendor
interoperability
-- Rate adaptation both at start-up and during operation (RADSL)
-- The transport of ATM cells over ADSL
-- Extending the highest data rates to over 8 Mbps
-- Reducing the overhead for increased upstream capabilities
Since January 1996, 18 vendors and service providers have made more than 150 contributions towards Issue II of the existing ADSL standard. Issue II is expected to culminate in a new issue of the current standard by the end of this year. To date, eight independent semiconductor companies have DMT-based ADSL projects underway or chipsets available, and more are continually entering the market. In fact, more than 40 vendors are actively developing DMT-based equipment. Meanwhile, semiconductor vendors continue to increase functionality, and reduce system chip count, power consumption and cost, to enable mass deployment of ADSL-based services.
"The standards process is a key ingredient for the successful evolution of telephone networks worldwide," said Tom Starr, chairman and ANSI T1E1.4 working group. "As evidenced by the accomplishments of this group, an open forum where all companies work together to develop specifications can bring a multitude of benefits to the industry. I am pleased with the high levels of cooperation demonstrated by the working group in the development of an Issue II specification for ADSL.** This will set the stage for multi-vendor interoperability."**
+++++++++++++++++++++++++++++++++++++++++++++++++++++++Has there been a decision or are they still slugging it out?
BTW, Whatever happened to that school in Conway, S.C.?
Amusedly waiting,
