Configuring SONET/SDH Interfaces

Synchronous Digital Hierarchy (SDH) is a CCITT standard for a hierarchy of optical transmission rates. Synchronous Optical Network (SONET) is an American standard that is largely equivalent to SDH. Both are widely used methods for very high speed transmission of voice and data signals across the numerous worldwide fiber-optic networks.

Configuring SONET/SDH Physical Interface Properties

To configure SONET/SDH physical interface properties, include the sonet-options statement:

[edit interfaces so-fpc/pic/port] 
sonet-options {
  aggregate asx;
  aps {
    advertise-interval milliseconds;
    authentication-key key;
    force;
    hold-time milliseconds;
    lockout;
    neighbor address;
    paired-group group-name;
    protect-circuit group-name ...
