Harris & Jeffries Announces High-Performance Frame RelayTM Signalling Software Subsystem, Release 2.0

Updated SVC Implementation Supports Frame Relay Forum FRF.4 and FRF.10 Implementation Agreements and ITU Q.922, and Q.933 Features; Achieves Call Set-up Rates in Excess of 8,000 Calls per Second (CPS)

DEDHAM, MA — May 27, 1998 — Harris & Jeffries, Inc. (H&J) announced today an enhanced version of its High-Performance Frame RelayTM Signalling Software Subsystem (HPFRTM SSS). Release 2.0 augments the user-to-network interface (UNI) SVC functionality (FRF.4) provided in release 1.01 with network-to-network interface (NNI) SVC functionality (FRF.10).

HPFR SSS allows manufacturers of frame relay access devices (FRADs), multiplexers, switches, routers and other frame relay products to integrate both UNI and NNI frame relay SVC capability into their equipment. The product is fully compliant with The Frame Relay Forum's FRF.4 and FRF.10 Implementation Agreements, including ITU specification Q.922 for reliable transfer of signalling frames and the portions of Q.933 and X.76 as specified by FRF.4 and FRF.10.

Manufacturers requiring only UNI SVC (FRF.4) support can purchase H&J's High-Performance Frame Relay UNI Signalling Subsystem (HPFR USS).

H&J's frame relay signalling products give users the flexibility to establish network connections on a demand basis, rather than requiring permanent virtual circuit (PVC) connections. HPFR SSS release 2.0 extends the utilization of SVCs from the user-side to the network-side, eliminating costly, manually administered permanent network connections. Instead, automatic connections are initiated by the end-user equipment and implemented by the intelligence embedded within the network.

SVCs Enhance Frame Relay Service, Benefits Users and Service Providers

According to Steve Taylor, President of Distributed Networking Associates, a Greensboro, NC based consultancy specializing in Frame Relay, "It turns out that the 'killer application' for frame relay SVCs is their enhanced manageability. The management of PVCs is one of the factors limiting Frame Relay's scalability and inhibits the utilization of full mesh networks. These manageability and scalability problems are exacerbated when multiple carriers are involved; hence, the reluctance on the part of some carriers to support NNIs. In reality, FRF.10 support should be the glue that's needed to bring both NNIs and SVCs to a stronger position in the marketplace. Service providers benefit through a reduction in operational overhead and better utilization of their networks, and users receive pass-through benefits with wider connectivity and lower prices."

"H&J's software architecture gives users considerable flexibility when integrating HPFR SSS into their own architectures, yielding quicker time-to-market and associated cost-savings. Our customers, the network equipment manufacturers, benefit with reduced time-to-market, differentiated features and the ability to purchase, integrate and ship quickly a product with market-leading capabilities," said William Glynn, Frame Relay Product Line Manager at Harris & Jeffries.

H&J's frame relay software is highly portable, processor and operating system independent and is interoperable with almost any frame relay network — enabling manufacturers of network equipment to develop products faster with reduced development risks.

The new HPFR SSS also incorporates a high-performance architecture with new ease-of-use facilities and a comprehensive developer's toolkit. The new architecture features several innovations developed for H&J's Soft-ATMTM asynchronous transfer mode (ATM) software product line. Among them are diagnostic traces, probes and other toolkit components to facilitate development.

Comprehensive Solutions Speed New Product Development

For a comprehensive frame relay solution, manufacturers can integrate HPFR SSS with High-Performance Frame Relay Core Services (FRF.1/FRF.2) which provides frame relay UNI and NNI support, world-class congestion management, and five different versions of LMI. To obtain a complete frame relay-to-ATM interworking solution, manufacturers can use H&J's HPFR ANI to provide Frame Relay-to-ATM Network Interworking (FRF.5) and HPFR ASI to provide Frame Relay-to-ATM Service Interworking (FRF.8).

All High-Performance Frame Relay software products feature H&J's Interoperability Guarantee that guarantees products developed using HPFR products will interoperate with other products that comply with The Frame Relay Forum's specifications.


In measured tests, HPFR SSS consistently provided in excess of 8,000 call setups per second. The tests were conducted using a Pentium II - 266Mhz PC with 96 MB RAM running Windows NT 4.0 (build 1381). These numbers were determined in laboratory testing with Q.922 disabled.

Pricing and Availability

High-Performance Frame Relay Signalling Software Subsystem release 2.0 is available now. Pricing of High-Performance Frame Relay and Soft-ATM products range from $15,000 to $80,000 per target system, per development license, depending on configuration purchased. Volume discounts may apply.
