[installation guide] hi MB, the installation guide was indeed a fun read... interesting angles: tho posted on the orctf website, the document itself contains no mention of orckit.. by all appearances it is produced by fujitsu network communications... including copyrights etc... just checked the fnc website, no sign that i could find of this document there... date of this document is september 98.. and in the copyright section it mentions that the document is "confidential"... which it no doubt was til recently... we might be getting a preview.. of the final draft and someone missed removing this... am guessing that orctf is not mentioned as the product will be billed as fujitsu's.. (tho some of those illustrations look awfully familiar) looked hard at the modem on the cover, but couldn't make out the text on the modem itself.. am guessing it will say fujitsu somewhere... would be interesting to know who is gonna be making these would be surprised if this is not the new modem that somo saw at the telecom israel exhibition.. and would imagine that when they are available (jan/feb?) they will have the new fujitsu/orctf adsl silicon inside.. bet fujitsu/orctf were waiting for the new silicon and now that it's (almost) here, things are gearing up for the consumer push ... thought the most interesting feature was the auto-software upgrade part on p 22: --- "When the ADSL link between the DSL Modem and the telephone company is established, the telephone company checks the software version against the DSL Modem. When this is happening, the POWER light is on and the MODEM light blinks. If the software versions are incompatible, the DSL Modem will automatically receive a software upgrade of the appropriate version. During a software upgrade, the POWER light stays on and the DATA and MODEM lights blink. The software upgrade is complete and the modem is operating at efficient capacity when the POWER, MODEM, and DATA lights are on." --- believe such functionality has been alluded to a few times including g.lite... but have never seen it spelled out... such a feature should be helpful/marketable moving forward as standards/upgrades are hammered out... as long as i seem to be running on (as usual) noticed a couple of interesting (new) things on the fnc website: the fujitsu factr/speedport platform is now being billed as vdsl capable... 51Mbps: --- "Broadband DSLAM Solution The FACTR access network can be easily upgraded to a DSLAM solution (SPEEDPORTâ„¢) which utilizes xDSL technology to provide each end-user with up to 51 Mbps of downstream and 1.6 Mbps of upstream bandwidth-on-demand for high-speed Internet access and telephony applications... FACTR Features... Broadband Configurations Broadband Multiple LAN interfaces xDSL (HDSL, SDSL, ADSL, VDSL , DAVIC A1)... "fnc.fujitsu.com --- and these orctf adsl chipsets seem to be configurable to provide symmetrical service up to 768 Kbps .. tho entirely logical , symmetrical adsl does seem like something of an oxymoron: --- "DSL Line Card Dual-density, rate-adaptive, Asymmetric Digital Subscriber Line (ADSL) modems, based on high-performance ANSI T1.413 standard discrete multi-tone (DMT) modulation, provide transmission at distances of up to 18,000 feet. Both modems can be configured independently of each other to provide asymmetric or symmetric digital subscriber line service. SPEEDPORT modems, designed in conjunction with leading xDSL pioneer Orckit Communications Ltd., are DSP-based to provide support for emerging standards and allow new features to be added as required... DSL CPE Modem Supports one DSL line Standards-based T1.413 DMT line code Transmit power: 13.5dBm ± 0.5dBm (135 ? load) Asymmetric operating mode: Downstream data rates of up to 8.192 Mbps Upstream data rates of up to 768 kbps Symmetric operating mode: Bi-directional data rates of up to 768 kbps ... "fnc.fujitsu.com --- for gte at least, had been guessing symetrical 768 kbps service was based on sdsl (hdsl) chipsets, guess not... am thinking now that gte/fujitsu/(orctf) won't be offering sdsl at rates above this til the new rok/(orctf) hdsl2 silicon is available.. and this will probably be pretty soon .. best wishes s
