TeleProcessing Announces Unique Multiple T1/E1 and Fractional T1/E1 Inverse Multiplexing Capability for OPERA Integrated WAN Access Systems.

SIMI VALLEY, Calif.--(BUSINESS WIRE)--Sept. 30, 1997--TeleProcessing Products Inc., a leading supplier of WAN access equipment and integrated access systems solutions, Tuesday announced the addition of an inverse multiplexer (IMUX) function module to its OPERA integrated WAN access product line.

The new IMUX module supports transmission of high-speed data across two to eight T1 and/or E1 lines with combined data rates of up to 15.808 Mbps. The new OPERA IMUX module meets the bandwidth- intensive demands of multi-megabit and fractional T3 class applications such as LAN-to-LAN connectivity, image transmission, high-speed data recovery, bulk file transfers and video conferencing.

"The OPERA IMUX is in a class by itself because it supports fractional T1 and E1. Bandwidth can be added to IMUX applications in 64 Kbps increments as opposed to standalone inverse multiplexers that only transmit at N x 1.528 Mbps," said Holly Sacks, TeleProcessing's vice president of marketing.

"This ability to allocate bandwidth at the DSO level means that IMUX high speed data transmission can be supported simultaneously with other wide area network voice or data applications," Sacks said. "Potential communications cost savings realized from this unprecedented level of flexibility and bandwidth efficiency are enormous."

The OPERA IMUX is also unique in that it provides users the ability to preprogram error thresholds, which trigger a drop of any T1/E1 link when excessive error or signal loss conditions are present. OPERA automatically adjusts the data rate of the remaining links until the dropped link is restored.

The IMUX function module provides a comprehensive menu of diagnostics including round-trip delay measurement, built in BERT (Bit Error Rate Test) and cross wire detection. It is paired with a new OPERA HSSI interface module (IMHSSI) which provides user- selectable HSSI or V.35 DTE connections.

The OPERA inverse multiplexer function module (FMIMUX) and associated interface module (IMHSSI) will ship in October 1997. The IMUX function module list price is $2195. The HSSI/v.35 interface module price is $450.

The configured system list price of an OPERA Opus 7 seven-slot integrated access system, with built-in digital access cross connection system and prEVENT Mapping, configured with one dual T1 module and IMUX function module plus HSSI interface module is $7890.

Because OPERA is a modular, scalable integrated WAN access platform, the remaining five slots can then be populated from an extensive menu of OPERA modules for additional voice and/or data applications. TeleProcessing will demonstrate OPERA and additional WAN access equipment product lines at booth No. 1063 at Networld + Interop in Atlanta.
