CrossComm completes ATM interoperability tests at MCI.

Corporation's new ATM Edge Router product line has successfully passed a series of interoperability tests conducted at MCI's networkMCI Developers Lab in Richardson, Texas. The tests were created by MCI as a way of testing ATM network integration by demonstrating interoperability between several leading ATM equipment suppliers.

Phase I of the recently completed tests connects network adapter cards to CrossComm's ATM Edge Router over MCI's Hyperstream ATM service. ATM switches from several vendors were also successfully tested with CrossComm for interoperability. CrossComm is also participating in Phase II of the tests, now underway, which is a more sophisticated measure of equipment compatibilities.

"We are very pleased to be involved in MCI's tests," said Tad Witkowicz, President and CEO of CrossComm. "We have invested heavily in the development of our ATM and LAN switching products, and to see them working in these types of field environments is a big step forward. Our ability to successfully interoperate with other leading ATM vendors, under the watchful eye of MCI, tells me our products are ready for primetime," he continued.

ATM Starter Kit Available for Pilot Programs

CrossComm has recognized the need by companies to be able to test ATM easily and inexpensively, and has just announced an ATM Starter Kit, which contains all of the components used in the MCI trials, including an adapter card, at an introductory cost of $31,900. CrossComm's ATM Starter Kit will enable customers to implement pilot programs, taking advantage of second-generation ATM technology, at significantly less cost than purchasing a single ATM switch from many other vendors. The cost and packaging of the ATM Starter Kit will be very attractive to companies wanting hands-on experience with ATM.

"CrossComm's ATM Starter Kit corresponds with the META Group's concept of an ATM "appetizer," said META's Tom Bain. "That is, users should find isolated areas of the network where small scale, cost-effective ATM deployments make sense to gain familiarity with the technology, before undertaking mission-critical ATM backbone projects."
