LDDS WorldCom and Ameritech team up to offer frame relay NNI

TULSA, Okla. (September 19, 1995)-- LDDS WorldCom has successfully completed frame relay network-to-network interface (NNI) connectivity with Ameritech Corp., becoming the first carrier to forge such links with every Regional Bell Operating Company (RBOC).

As a result of this connection, LDDS WorldCom customers can interconnect with the Ameritech frame relay network via LDDS WorldCom's global frame relay network. The addition of Ameritech NNI connectivity into the Chicago area means LDDS WorldCom now offers NNI connections across the United States. "LDDS WorldCom is the first and only Inter-Exchange Carrier (IXC) to have a frame relay network interconnected to all of the RBOC's networks," said Emily Hansen, frame relay product manager for LDDS WorldCom. Customers benefiting from NNI are those with multi-LATA, multi-state or multi-LEC locations.

With NNI, Ameritech frame relay customers can choose to extend their network outside the Ameritech region, while avoiding the cost of developing a dedicated long-distance network. Instead, customer traffic flows over a shared network. Connections between the two networks follow the Frame Relay Forum's approved Network-to-Network standards. "NNI is the next logical step in the evolution of frame relay," added Hansen. "By taking advantage of our NNI connectivity with local carriers like Ameritech, customers can reduce network costs by up to 50 percent over standard IXC frame relay offerings."

Tom DeHahn, transport market manager for Ameritech long distance industry services also emphasized the economics represented by the NNI agreement. "Ameritech Frame Relay Interconnect will help carriers like LDDS WorldCom provide more cost-effective solutions through closer port connections and shared NNI facilities a primary goal of our UltimateLink suite of services," said DeHahn. Port speeds reach T1 on both networks. All standard LDDS WorldCom frame relay Committed Information Rates (CIRs) are offered and both networks support bursting.
