In the Rate Center Reports, the Pooling Status designation is defined as follows:
2. Mandatory State (M) - Pooling was implemented in this rate center pursuant to a state commission order. This rate center is not in a top 100 MSA, but has one or more pooling-capable service providers, and is considered a mandatory pooling rate center. 3. Mandatory Single Service Provider (M*) - This rate center is in the top 100 MSA, but has only one service provider that has numbering resources. This rate center will be considered optional under these conditions and designated as M*. When a second service provider receives numbering resources in this rate center, the designation will be changed to M for Mandatory. 4. Mandatory State Single Service Provider (M*) - Pooling has been implemented in this rate center pursuant to a state commission order. This rate center is not in a top 100 MSA and has only one service provider that has numbering resources. This rate center will be considered optional under these conditions and designated as M*. When a second service provider receives numbering resources in this rate center, the designation will be changed to M for Mandatory State 5. Optional (O) - This rate center is not in the top 100 MSA and any service providers with numbering resources in this rate center may elect to pool at its option. Service providers may voluntarily participate in thousands-block number pooling in an Optional rate center outside the top 100 MSAs. 6. Excluded (X) - This rate center is
not in a top 100 MSA and no service provider is currently participating
