[rok/asnd/sdsl/hdsl2 silicon?]
hi tom,
have you noticed this one? june seems a little early and orctf is not mentioned... but asnd will be using rok hdsl silicon for their sdsl solution... speeds described @ 1.5 Mbps over a single twisted pair...sounds a lot like rok/orctf hdsl2 to me...
you-know-who has been collaborating with rok on jointly developing a family of hdsl2 chips for symetric transmission @ 1.5 Mbps over single twisted pair ... since last nov... products due this year... silicon manufactured by rok...
i might be needing a break as i seem to be seeing an orctf behind every tree...
fwiw: guess i just haven't taken sdsl seriously.. altho i knew it, i never noticed... the connection between sdsl and hdsl... same silicon... :) .... also apparently with a little tweaking of their line codes sdsl and hdsl can support analog voice along with data just as adsl and vdsl ... believe this isn't typically the case now, but believe we'll see this featured more and more as dsl rolls out ...
today, apparently depending on distance required, sdsl can be configured in (symetric) increments of 128 kbps... up to 1.024 Mbps.. tho typically believe it is only used up to 768 kbps for 13,000 feet or so... well i guess hdsl2 is gonna double those speeds.. maybe for less power/ less $... and with rok as a silcon partner who will be shipping product shortly, orctf looks positioned rather well... (and maybe some revenues from silicon eventually??)
also thought i'd remembered a reference to sdsl in the gte telechoice write-up... and sure enuf it is listed as one of 5 "enhancements" expected for the fujitsu/orctf platform in the next 6-12 months... think they're probably refering to sdsl using hdsl2 silicon..
looking at GTE's service packages... "silver" is 384/384 kbps and "gold" is 768/768 kbps... so it looks like sdsl will be offered from day 1... curious sdsl hasn't been mentioned by name.. know speedport supports sdsl as well as adsl so that fits ... in any case: "Ascend Communications and Rockwell Deliver Breakthrough Speeds in Symmetrical Data Access
Now Network Service Providers Can Use Ascend's TNT and DSL Pipeline To Offer High-Bandwidth Solutions Over Single Twisted Pair
ALAMEDA, Calif.--(BUSINESS WIRE)--May 18, 1998-- To meet the growing demand for multifunction network access equipment that utilizes xDSL technologies, Ascend Communications, Inc. (NASDAQ:ASND - news), the leading provider of wide area network (WAN) solutions for network service providers, today announced support for Rockwell Semiconductor Systems' Single-Chip HDSL Transceiver to power Ascend's Single Pair Symmetrical Digital Subscriber Line (SDSL) offerings. The joint solution allows network service providers to provide customers with 1.5 MB per second symmetrical data access - a speed formerly reached only with asymmetrical digital subscriber line (ADSL) - for both data and voice. This solution marks the first time a Rockwell HDSL chip has supported 1.5 MB per second speeds over a single twisted pair..." biz.yahoo.com
and thanks for the first call info... and just noticed the follow-on offering..
now that's something to chew on... timing that is... hope orctf has some news up their sleeves..
