The diagram on your left illustrates another scenario for a Wireline Local Call.

Scenario 7

Local call outside ported area - LEC without LNP/LRN capability:

  1. Caller B makes a call within their LCA, but from outside the Metropolitan Statistical Area (MSA) and ported area, to Caller C.
  2. LEC-4 is the N-1 carrier and at some time may be required to perform the "database dip" to determine the LRN to route the call to LEC-2. Until that time, LEC-4 should arrange with LEC-1 (or LEC-2) to terminate default routed calls.
