Ariel Announces Octal T1/E1/PRI CompactPCI Network Interface CardSwitches 240 PSTN Calls On A Single 6U Card.Business Editors and High-Tech Writers CRANBURY, N.J.--(BUSINESS WIRE)--Feb. 5, 2001 Ariel Corp. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :ADSP ADSP - AppleTalk Data Stream Protocol ), a leading supplier of Microsoft Windows(R) NT and Linux remote access solutions for technical OEMs, Monday announced a CompactPCI-based T1/E1/PRI network interface card for designers of high-density, telco-quality network access equipment. The new hot-swappable card, dubbed the RS4100C, features eight T1/E1/PRI network interfaces, which enable it to switch up to 240 PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. calls (analog, digital or voice) and terminate up to 120 digital calls. "The RS4100C's robust packaging, high port density, standard interfaces, and programmability make it ideal for designers of high-density, high-availability voice and data processing systems who require E1/T1 connectivity and telco quality," said Ned Viands, product manager for technical OEM products at Ariel Corp. "In addition to packing eight T1/E1/PRI interfaces on a single CompactPCI card, the RS4100C is hot swappable, features standard CompactPCI and H.110 interfaces, and provides four programmable Texas Instruments DSPs." The RS4100C is equipped with standard CompactPCI and H.110 TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. (Time Division Multiplexed) interfaces, which make it easy to combine the RS4100C with voice, fax, and modem processing cards in a CompactPCI-based network access system. For example, by combining multiple RS4100C network interface cards with MP5000 168-port DSP/modem pools, OEMs can quickly configure high-density network access systems that process up to 1680 modem, ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. , PHS (Personal Handyphone System) A TDMA-based cellular phone system introduced in Japan in mid-1995. Operating in the 1880-1930 MHz band, PHS uses microcells that cover an area only 100 to 500 meters in diameter, resulting in lower equipment costs but requiring more base , or GSM calls in a 12U space. The T1 version of the RS4100C includes four programmable Texas Instruments TMS320C5410 digital signal processors. These processors are presently used for tone detection in T1 Robbed-Bit Signaling environments. Ariel's plans include providing documentation that shows OEMs how to gain access to these DSP resources. This will enable OEMs to download proprietary or commercial-off-the-shelf software for functions such as vocoders, echo cancellers, speech analysis, data and fax modems, encryption, and many others. The RS4100C is hot swappable, which maximizes network availability by enabling the board to be inserted and removed from active systems while the system is running without disrupting service. The RS4100C also enhances availability by utilizing a rear panel I/O card that concentrates all cabling in the rear of the chassis. This enables the active front panel card to be quickly inserted and removed without having to plug and unplug cables. The RS4100C supports T1 Robbed-Bit Signaling and T1/E1 Primary Rate ISDN (PRI PRI: see Institutional Revolutionary party. (Primary Rate Interface) An ISDN service that provides 23 64 Kbps B (Bearer) channels and one 64 Kbps D (Data) channel (23B+D), which is equivalent to the 24 channels of a T1 line. ) signaling. It also supports T1/E1 clear channelized Refers to an architecture that transmits data in channels. It often refers to the 64 Kbps channels in T1 lines, which were originally developed to handle digitized voice streams (TDM). See TDM. signaling, which enables it to be used with low-cost Inter Machine Trunks that work with out-of-band signaling like SS7. Line coding support for the RS4100C includes T1 AMI and B8ZS (Binary 8 Zeros Substitution) An encoding method in T1 and E1 transmission that substitutes a special bit pattern for 8 consecutive zeros in order to maintain ones density. See ones density. , as well as E1 HDB3. Framing format support includes T1 ESF and D4, as well as E1 G.704. Pulse Code Modulation pulse code modulation: see modulation. See PCM. (data) Pulse Code Modulation - (PCM) A method by which an audio signal is represented as digital data. Support includes u-law and a-law. Signaling types include T1 wink start, delay dial, and immediate start/dial. ISDN support includes HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. , Q.921, and Q.931. The RS4100C is compatible with a variety of Primary Rate ISDN protocol variants, including 4ESS, 5ESS, National ISDN-2 (NI-2), DMS-100, ETSI (European Telecommunications Standards Institute, Sophia Antipolis technical park, Nice, France, www.etsi.org) A non-profit membership organization founded in 1988, dedicated to standardizing information and communication technologies (ICT) throughout Europe. NET5, NTT, and TS014. The RS4100C meets worldwide standards for safety and EMI/RFI emissions. Included are USA UL1950, FCC Part 15 (Class A), and FCC Part 68: Canada CASA Ca´sa n. 1.

An OEM Development Kit is available that includes a Red Hat (NASDAQ: RHAT) Linux reference driver, utilities, and all the documentation needed to write drivers for other operating systems. A Windows NT driver is also available to technical OEMs. The RS4100C costs $10,500, including five years of hardware support and one year of service support, and will be released to manufacturing this month.
