The Positron OSIRIS multi-service Platform (MSP) is an integrated access solution for the rapidly expanding synchronous optical network (SONET) broadband markets. It delivers the most cost-effective, compact and simple-to-deploy solution for multiservice traffic such as data, voice and video.
The OSIRIS solutions are designed to map various types of signals over a fiber ring. The EC-1 mappers transport an STS-1 signal (51.84 Mbps) on a SONET signal. The EC-1 Bulk mapper processes the STS-1 signal at the STS-1 level, enabling any type of payload to be transported. The EC-1 virtual tributary (VT) mapper processes up to 28 VT1.5 from 1 STS-1, keeping complete VT1.5 visibility. The EC-1 time slot assignment (TSA) mapper processes up to 28 VT1.5 from 1, 2, or 3 different STS-1s via TSA.
