MICROCOM BRIDGE/ROUTER PASSES FRAME RELAY TEST BY AT&T, SPRINT, WILTEL, NORTHERN TELECOM AND NYNEX

 NORWOOD, Mass., Feb. 9 /PRNewswire/ -- Microcom, Inc., (NASDAQ: MNPI) a leader in innovative PC connectivity solutions, today announced that its version 6.1 multi-protocol Microcom Bridge/Router(tm) (MBR(tm) has successfully completed frame relay compatibility test conducted by Sprint, Northern Telecom, AT&T, WilTel and NYNEX. In separate trails staged by each carrier, Microcom's MBR/6500 for packet- switched networks managed hazardous conditions and met performance criteria normally found in corporate internetworks.
 Known for its exhaustive frame relay compatibility trials, Sprint tested the MBR/6500's ability to terminate a wide area network (WAN) link experiencing a high error rate. Transmitting data on a link showing high error rates is both inefficient and expensive for users. The test determined that the MBR/6500 quickly recognized transmissions showing high rates of erroneous data. In a real life application, the MBR/6500 would save users substantial time and transmission costs by immediately dropping the link and re-routing data via a more reliable path.
 Northern Telecom formulated 76 test cases that verified interoperability between the MBR/6500 frame relay router and Northern Telecom's S/DMS SuperNode. The trials included performance tests measuring PING Delay and file transfer throughput of two MBR/6500s interconnecting Ethernet LANs via a frame relay network. The test also verified that prolific TCP/IP applications used on enterprise internetworks can run on top of the MBR/6500's frame relay permanent virtual circuits (PVC).
 In addition to performance trials, the MBR/6500 passed frame relay physical link and logical link failure tests measuring how efficiently the bridge/router detected and recovered from a link failure, a condition opposite that created in the Sprint experiments.
 At the prestigious Bell Labs Testing Facility, AT&T's Developmental Relations Group (DRG) put the MBR/6500 through rigorous testing for
compatibility with their Interspan(R) Frame Relay Services. The


MBR/6500 met AT&T's certification criteria that reflected concerns regularly faced by corporate MIS and network managers, including physical connection, data transport, frame relay routing capabilities and performance. In a WAN including products from Stratacom and Wellfleet, the Microcom Bridge/Router demonstrated the capability to successfully interoperate with other third-party equipment, an essential requirement of most corporate internetwork environments.
 Similar tests were conducted by WilTel to verify the compatibility of the MBR/6500 with the WilTel WilPak frame relay network and by the NYNEX Science and Technology Lab for compatibility with NYNEX's Frame Relay Service.
 The MBR/6500 is Microcom's multi-protocol bridge/router designed to interconnect small and medium-size LANs via frame relay and X.25 networks. The bridge/router supports up to 60 virtual circuits, each providing high throughput with link speeds up to 2.048 Kbps. Among the outstanding features found in version 6.1 of the MBR/6500 are its 4:1 data compression algorithm and simple plug-and-play installation.
