Northern Telecom Ltd now says it has substantially completed negotiations with Nynex Corp for a five-year switching systems contract: The value of the contract, which is substantially less than $1,000m, was not revealed in the news release, it said, since the agreement with Nynex did not allow it to reveal the value of the contract – so instead it estimated the value of the total project, which includes supply of initial switching systems, software and hardware upgrades, system extensions, remotes and other items and Over five years, we estimate that Northern Telecom will supply about $1,000m in products and services to Nynex, it said, adding that this was based on assumptions about economic conditions, network growth and customer satisfaction – We believe our estimate properly reflects the potential value of the agreement to Northern Telecom.
