OMS 3250

Product DescriptionOMS3250N1NETWORK OPERATOR; it has been allocated for tandem connectionmonitoring function5.2.2 Connection Supervision FunctionsOMS3250 has been conceived to support Higher Order Supervisory-Unequipped functionality.The Higher Order Supervisory-Unequipped function comprises the atomic functions HigherOrder Supervisory unequipped termination source (Sns_TT_So) and sink (Sns_TT_Sk), as theyare defined by ITU-T revised Draft G. 783 Recommendation.The Higher Order Supervisory-Unequipped function enables supervision of unassigned HOconnections on VC-4 paths.5.2.3 Tandem Connection MonitoringOMS3250 is open to support VC-4 Tandem Connection Monitoring functionality according toETSI /ETS 300-417-4-1.A VC-4 Tandem Connection is set-up to provide monitoring for a segment of a path, e.g. fromwhere a path enters an operator's domain until it leaves that domain or is terminated. Specificinformation is added by the source function at the ingress of the Tandem Connection. Thisinformation is then extracted together with other path overheads by the sink function and isused to establish defect detection and performance monitoring for the path segment associatedto the Tandem Connection.Page 32 of 74 Copyright – Refer to Page 2 Issue 1
