FEATURE OPERATION:
The ESP's Uniform Access Number (UAN) traffic is delivered from the originating
end office to the associated TOPS Tandem switch over a dedicated trunk group.  
The TOPS Tandem switch provides the translation and routing functions required
to support the service.  The ESP's clients will dial the UAN, which will be
routed to the associated TOPS Tandem switch.  The TOPS Tandem switch translates
the UAN and then routes the traffic to the ESP's location.  The UAN service is 
required to support the Automatic Number Identification (ANI) and Custom Service
Areas (CSA) basic service elements.

The originating end office translations are set to route the UAN traffic using a
unique NXX as a trigger.  The 440 NXX will serve the BellSouth region, the 
530 NXX will serve South Central Bell only, and the 930 will serve Southern 
Bell only.

A dedicated one way trunk group from each of the TOPS Tandem switch subtending 
end offices is used to deliver the UAN traffic to the TOPS Tandem switch.
This trunk group is designed to deliver the called number (UAN) and calling
line ANI to the TOPS Tandem switch.  The Operator Services Signaling (OSS)
protocol is used to deliver the information over the trunk group.

The TOPS Tandem switch collects the incoming information and translates
the UAN to determine how the call should be handled.

The UAN calls can be delivered to the ESP either through the normal circuit 
switched network or using dedicated trunks from the TOPS to the ESP's location.
If ANI delivery is desired, the trunk side option is required.

At the present time, this service will only be offered to ESPs through the
General Subscriber Services Tariff (GSST).
