Features and Services
Off-Net numbers that terminate at an ESN Node or Main, or at a
Conventional Main, can be routed through the private network by means of
TIE trunks. BARS/NARS Off-Net Number Recognition prevents
unnecessary TO and FROM terminations through CO trunks, at the
terminating end, when a caller dials a DID or Direct Distance Dialing (DDD)
call to a location in the private network. Calls are handled on the basis of
customer-defined parameters stored in Network Translation Tables and
Supplementary Digit Recognition/Restriction Blocks.
Detailed information is provided in Basic and Network Alternate Route
Selection: Description (553-2751-100).
BARS/NARS 11-Digit Translation
This feature expands the ESN BARS/NARS translation capabilities from a
maximum of four digits to a maximum of 11 digits for route selection.
Possible conflicts between translatable codes (NPA, NXX, LOC, SPN) are
eliminated by 11-Digit Translation. By allowing translation of more than four
leading digits, unique nonconflicting routing to a destination is possible.
More than one route list can exist for each specific code of a type. For
example, the NXX 727 could only translate into one route list previously.
With 11-Digit Translation, up to 128 route lists for BARS and up to 256 for
NARS may be defined, extending translation deeper into the dialed code. The
codes must be leftwise unique. If an NXX of 7271 is defined, any other 727
entries must be extended to four digits.
BARS/NARS 11-Digit Translation is discussed in greater detail in the Basic
and Network Alternate Route Selection: Description (553-2751-100).
Network Authorization Code
The Network Authorization Code (NAUT) feature provides up to 50,000
authorization codes. Network Authorization Code (NAUT) incorporates all
the features of the BAUT feature, adds a conditionally last option for entering
an Authorization Code after dialing an ESN call, and enables the attendant to
enter an Authorization Code. Network Authorization Code (NAUT) is
described in detail in Basic and Network Alternate Route Selection:
Description (553-2751-100).
