AVON, Colo.-NSN Network Services introduced Broadcast TNPP for paging networking, technology that combines Telocator Network Paging Protocol sources from a number of locations into one data stream, enabling point-to-multipoint communications between terminals.
TNPP is the protocol that allows paging terminals to talk to one another. In Broadcast TNPP, the signals of all operators involved are broadcast within the satellite’s range, on the same frequency. NSN spokesman Todd Theel said the current point-to-point technology typically operates as a loop system, a scenario where paging transmission can break down if one site has a problem.
For carriers, a key benefit of Broadcast TNPP is the ability to extend coverage for their local and regional customers.
Working closely with GTE Corp. and Zetron Corp., NSN of Avon, Colo., developed a custom software package that allows pages to be classified in zones. Thus, a Seattle paging user who has local paging service only could receive paging service in Miami-for as little as one day-if the user’s carrier is part of a broadcast TNPP network.
“Local traffic goes to everybody,” said Theel. He added that as many as 250 operators could operate on one broadcast frequency.
Broadcast TNPP uses proprietary Time Division Multiple Access VSAT control systems developed for NSN, which interact with the customer TNPP data before and during network operation.
Tupelo, Miss.-based Southern Net, the Southern Network Association of Paging, already has implemented Broadcast TNPP at 21 sites, said Theel. NSN has been developing the technology since last fall, and started installing the systems in May.
