Jetstream offers gateway for DSL voice By Loring Wirbel EE Times (12/01/98, 3:14 p.m. EDT) SAN JOSE, Calif. — Jetstream Communications Inc., a voice-processing specialist with roots in ISDN, has developed a packet-to-circuit gateway for using digital-subscriber-line networks to deliver dial-up voice to end users. Jetstream's Unity access network can use industry-standard asynchronous-transfer-mode switches, as well as ATM-based DSL-access multiplexers (DSLAMs), to let competitive local-exchange carriers get directly into the voice business through DSL hardware. Jetstream won't have its CPX-1000 ready for shipping or pricing until early 1999, probably around the time of the January ComNet show in Washington. But it is talking to data-oriented competitive local-exchange carriers this week in Las Vegas at the ALTS show, a special trade show for CLECs and facilities-based Internet-service providers. David Frankel, founder and chief technology officer at Jetstream, said many CLECs have talked about getting into voice services, but only through voice-over-Internet Protocol, wherein voice is packetized end-to-end and carried over the IP network. A DSL architecture must assume the existence of many circuit-switched calls and must provide switching between circuit and packet worlds. Special equipment is required at only two points in the network. An integrated access device (IAD) that can multiplex voice and data on one line is necessary at the customer premises. And at the central office, a local service gateway that connects directly to a CLEC's Class 5 circuit switch is needed. Jetstream plans to be the sole designer of the Unity CPX-1000 gateway for circuit-to-packet conversions. But at the customer premises, the company wants to work with several manufacturers to develop access devices compatible with Jetstream's own multiplexing methods. "We will develop reference designs and prototypes, to be sure, but we wanted to engage with partners because we knew we couldn't do all types of IADs ranging from a home office to a branch office," Frankel said. Jetstream is keeping a close eye on the emerging Media Gateway Control Protocol and will make sure its systems linking IP and Signaling System 7 networks are compatible with MGCP. In general, Frankel observed, most vendors in the gateway field tend to be larger telco-equipment vendors that are familiar with circuit switches but largely unfamiliar with DSL. Conversely, he said, most DSL-equipment specialists deal only with CLECs and haven't yet looked at developing effective circuit-switched gateways. Few startups or existing players have probed voice gateways for DSL thus. CopperCom Inc. is one known exception. Jetstream is pitching Unity as a direct replacement for T1 leasing. It stresses that payback periods for equipment amortization can be cut by moving more circuit-switched voice over DSL. The CPX-1000 gateway system will perform routing and call-control signaling as well as packet/circuit conversion. Jetstream will disclose more architectural details in early 1999. Another important piece of the architecture Jetstream will offer to alternative carriers is a dedicated element-management-system software suite, based on the Common Object Request Broker Architecture (Corba), that can provision and maintain customer voice and data services over as many as 10 CPX-1000 gateways. A single software interface will be able to manage 25,000 access devices at the customer premises, or up to 100,000 lines. Jetstream already has conducted interoperability tests to show that its gateway will interoperate with leading circuit switches, such as those from Lucent and Nortel. Between this week's ALTS show and the ComNet show at the end of January, Jetstream will test its system with leading ATM switches and DSLAMs. froland.

GlobeSPAM gives in, DMT Chipsets available I pulled the posts below from the SDLI Thread. I now have no doubts about any of the Major Companies in DSL, as many were stuck with GlobeSPAM as their only source for chipsets. Things continue to look great for a DSL Rally. With PAIR at $7. & WSTL at $6. these are bargains, especially PAIR! Those who have held their faith in AWARE have been rewarded Up $16. since Oct. (Way to go Scrapps) If you have your Ear to the tracks, you might be able to hear the train coming. JW@KSC Disclaimer: Always do your own DD, you, and you alone, are responsible for your investment decisions. Note to Jon K. and others who are still confused on the differences between DMT and CAP, at the end of my paper on WHY SDMT for VDSL ( not posted here yet) I wrote the following: In closing I would like to attempt to bring home the points covered above, in a much simpler terms, this is for those who find the above confusing. Since many of you may be audiophiles, or at least enjoy the sound of a decent stereo system. Pull out an old 45rpm record or an old Album. Turn the volume way up, and play it. Now don't those Clicks and Pops make you cringe, it's almost sounds as if they could be damaging to your speakers. This is your DATA on CAP, any questions? Now put on a CD, I suggest Life in The Fast Lane, by DMT.

Further evidence of this knowledge lies in MIR's ability to know investor and researchers reactions. "I can't think of anyone who'll get a bigger smile out of this than you:" When asked to comment, JW@KSC was silent, though we must report our observation's: JW@KSC was GFETE (Grinning From Ear To Ear) After ten minutes, JW@KSC, noted author of ADSL papers and quoted comments, who in the early days of ADSL development, defined to many DSL Investors that Discrete Muli-tone (DMT) would succeed in winning the ADSL Modulation Wars due to its inherent characteristics to handle noise on Copper Telephone Lines Vs Carrierless amplitude modulation (CAP) which could only handle noise when given Infinite Complexity, which could only be gained in theory, awakened from his trace like state,only to say four words, and then returned to GFETE.

Such components are used on the subscriber side as well as in the PBX and can be downloaded remotely. GLOBESPAN's DSL equipment is destined to respond the strong demand for high-speed, feature rich Internet access solutions. Thanks to this new technological development by Globespan, telecommunications operators can enrich their offer with new services, and high bandwidth Internet access en particular. GLOBESPAN Semiconductor is one of the largest suppliers of DSL modem chipsets that enable users to transfer data over standard telephone copper wire at speeds which are over a hundred times faster than with today's popular V.90 modems. The company's founding technical team began developing advanced modem algorithms and a DSL (Digital Subscriber Line) optimized, billion operations per second (BOPS), software downloadable digital signal processor (DSP) at AT and T Laboratories. Today, GLOBESPAN's fifth generation technology and five years of field experience have made it the only company offering production quantities of commercially deployable DSL solutions (ADSL, MSDSL, HDSL, RADSL) to more than sixty equipment manufacturers worldwide representing 80% of the DSL market. >>>>
