OSIRIS EC1 Mapper Unit

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.

EC-1 Mapper Technology

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.

Benefits:

  • All mappers feature remote circuit testing and loopback
  • The EC-1 Bulk mapper has the capability to carry unchannelized traffic
  • The EC-1 VT and EC-1 TSA mappers feature VT path switching
  • The EC-1 TSA mapper performs time slot assignment and optimizes bandwidth usage
  • Each mapper provides an ideal solution for electrical network interconnection

Features:

  • All mappers feature performance monitoring on EC-1 line and section overheads
  • All mappers perform failure detection
  • The EC-1 Bulk mapper enables you to drop and insert an STS-1 with STS-1 granularity
  • The EC-1 VT mapper enables you to drop and insert an STS-1 with VT1.5 granularity
  • The EC-1 TSA mapper enables you to drop and insert up to 28 VT1.5s from any STS-1
