This last diagram illustrates the last scenario for a Wireless Local Call.

Scenario 12

Wireless local call outside ported area - Conforming CMRS:

  1. Mobile Caller F makes a call within the LCA, but from outside the MSA and the ported area, to Caller C.

  2. CMRS-1 is the designated N-1 carrier and performs the "database dip" to determine the LRN, and then routes the call to LEC-2. If no direct connection exists between CMRS-1 and LEC-2, calls may be terminated through a tandem agreement with LEC-1.
