Synchronous Optical Network (SONET) is network specification designed to run on optical fiber. Packet Over SONET/SDH (POS) maps IP datagrams into the SONET frame payload using the Point-to-Point Protocol (PPP).
Introduced to the international standards body ITU-T in 1985, SONET was modified to support ITU-T applications. This modified SONET was renamed Synchronous Digital hierarchy (SDH).
SONET is the protocol for North America and Japan while SDH is the definition for Europe.
Use the commands in this chapter to:
- Configure SONET on Avici router Packet-Over-SONET/SDH (POS) interfaces
- Enable and disable SONET/SDH interfaces
- Set the characteristics of the SONET/SDH interface
- Display SONET/SDH statistics and interface settings
The following terminology is used throughout this chapter:
A SONET path is the logical connection between the two points on a connection where the SONET frame is assembled (on the sending side) and disassembled (on the receiving side). The remote end of a SONET path is referred to as the path-far-end.
A SONET line is the transmission medium between the two points. The remote end of a SONET line is referred to as the line-far-end.
A SONET section is any portion of a SONET connection such as a segment of optical fiber between two repeaters, the repeaters themselves, or a multiplexer.
