	1.	ISSUE STATEMENT:  

		Setup:

All databases are correct.
Subscriber B (212-239-1234) has ported his number from EO2 to EO1.
EO1 and EO2 are connected by an IXC which is not LNP capable.
Subscriber A is connected to EO1.
EO1 is connected to the IXC by an MF trunk.
Subscriber A has an alternate carrier for Intra-LATA toll calls.
Subscriber A and B are in different rate centers, but connected to the same end office
(EO1).

Action:
A calls B.
Even though subscribers A and B are in the same switch, this is an Intra-LATA toll call and subscriber A has chosen an alternate Intra-LATA carrier (IXC).
EO1 does not dip, but sends the call to the Intra-LATA IXC.
The intra-LATA IXC is not LNP capable, so it does no dip, and sends the call to EO2, where subscriber B’s number is vacant.

Loop:
EO2 dips the database and returns the call to the intra-LATA IXC.  The intra-LATA IXC returns the call to EO2.
