Teleprotection Service Provisioning
Prerequisites
To create and deploy a Teleprotection service, both NEs which are meant to be the service endpoints (Initiator NE, Terminator NE) need to:
• be manageable;
• be present in NP and ENP domains;
• have at least one Teleprotection unit which is assigned and still has capability in terms of:
− supporting the required type of teleprotection,
− number of interfaces,
− number of Pseudowires;
• be operating in required Termination Mode;
• provide the required interface configuration type (e.g., IEEE C37.94).
Transport Service requirements:
• VPWS Service Profile exists which meets Teleprotection service bandwidth requirements or has flexible bandwidth.
• The VPWS Service Profile must have fixed (i.e., NOT variable) tunnel protection settings; otherwise it cannot be selected during Teleprotection service creation.
• For Hitless services, only Service Profiles with unprotected tunnel are selectable (“protection=false”).
• For 1:1 services, only Service Profiles with protected tunnel are selectable (“protection=true”). 1:1 protection mode is not recommended for teleprotection services.
• Link path between Initiator NE and Terminator NE exists and meets bandwidth requirements considering Service Profile Class Type allocation.
