2.18.9 Loop Detection

Loop detection features:

• The Loop Detection feature design is both simple and flexible by using a Loopset table consisting of up to 12 pointcodes (OPCs) and comparing only the OPC of an MSU on a per GTT Translation basis requires the GTT translation to have a loopset provisioned.
• No assumptions/rules are imposed, everything is provisional whether concurring or opposite direction defines a ”Loop”, whether Customer using Capability Point Codes or True or Secondary Point Codes, which node is Adjacent and which is not, which node is mate and which is not.
• Detects looping on “multi-hop” translations and “single-hop” ones.
• Allows provisioning “Loops” for each Global Title Translation (GTA record).
• Allows provisioning/re-using same Point Codes in different LoopSets.
• Allows re-using same LoopSets for different Global Title Translations (GTA records).
• Allows provisioning “Loops” for each GTT Action record.
• Allows re-using same LoopSets for different GTT Action records.
