Abstract
A cellular telephone system provides coverage during cluster testing in which a new mobile switching center (MSC) that is to replace an old MSC is cut into the cellular telephone system for testing. A trunk group is built between the old MSC and the MSC. In addition, a signaling link is built between the old MSC and the new MSC. The new MSC is also assigned a unique point code to differentiate the new MSC from the old MSC during testing. In addition, the new MSC is provided with a new range of temporary local dialing numbers (TLDNs) for use during cluster testing.
