19 3/8 X 19 7/16. No news that I can find. Here's a post from another thread. No news just information. Subj: Re: Residential Gateway; Was [xDSL] Paradyne MVL Date: 98-02-04 01:29:52 EST From: trmmvm@ICSI.Net (Tim and Malinda) Sender: owner-xdsl@ListService.net Reply-to: xdsl@ListService.net To: xdsl@ListService.net Question - "The UAWG is working on the concept of splitterless ADSL, where you need no installation work at customer premises. But without the POTS splitter, how can the original advantage of ADSL be maintained, ie, it overlays, without interfering with the analog, voice traffic or nay other analog services, already existing ?" Answer - Standard analog modems operate in the voiceband spectrum, from zero Hertz to 4kHz, and the 4 kHz limitation is near exhaustion. DSL modems can utilize bandwidth well beyond 4 kHz - up to 1.1 Mhz of spectrum. However, current central office (CO)voice equipment does not know to "look for" information and signals outside the 4 kHz voiceband. Thus, for any DSL service, the local exchange carrier (LEC) must install new equipment to allow the subscriber to use this capacity for faster communications. Instead of requiring a field technician to install a splitter, DSL Lite relies on technology embedded in the PC modem. These DSL modems are priced comparably with traditional analog modems, and work with existing phone jacks. The great benefit of this "splitterless" technology is that the existing phone service is unaffected by adding DSL. The phone signal gets split and continues on its way to the local digital switching system. The DSL signal then terminates on the DSL concentration equipment and is groomed on a larger circuit. The service is then transported via the local carrier's frame relay or ATM backbone network, where it is delivered to the ISP's POP. The DSL data never traverses the public switched telephone network (PSTN) switches. Source- aware.com
