CRANBURY, N.J. Ariel Corp. has introduced a PCI-based T1/E1/PRI network interface card for designers of high-density network access equipment. The RS4100 features four T1, E1 and primary-rate ISDN (PRI) interfaces, enough to switch up to 120 public switched telephone network calls-analog, digital or voice-and terminate up to 60 digital calls.
The unit's time-division multiplexing ribbon cable interface supports MVIP signaling (H.100 support is planned). According to Ariel, that facilitates direct connection to voice, fax, modem and other media-processing boards.
The interface card supports T1 robbed-bit signaling; T1, E1 and PRI signaling; and T1/E1 clear channelized signaling. Line coding support includes T1 AMI and B8ZS, as well as E1 HDB3. Framing-format support includes T1 ESF and D4, as well as E1 G.704. Pulse-code modulation support includes T1 u-law and E1 a-law. Signaling types include T1 wink start, delay dial and immediate start/dial. ISDN support includes HDLC, Q.921 and Q.931.
The card utilizes the Ariel Access Architecture with a multi-function PCI bridge. An OS-independent application programming interface facilitates the design of modular multifunction driver sets that can be upgraded and moved from one board to the next, the company said. The card is compatible with a variety of PSTN switches, including 4ESS, 5ESS, National ISDN-2, DMS100 and ETSI NET5. It consumes 9 watts.
The interface card package includes an OEM development kit with a Red Hat Linux 6.1 reference driver, utilities and documentation needed to write drivers for other operating systems. A Windows NT driver is also available to technical OEMs.
The price is $3,609, including five years of hardware support and one year of service support.
