Incoming Trunk Group Exclusion (ITGE) provides full ten-digit restriction
for NPA and SPN codes, seven-digit restriction for NXX codes, and three-
digit restriction for Location Code (LOC) codes.
Detailed information on this enhancement is provided in the Basic and
Network Alternate Route Selection: Description (553-2751-100).
NARS Multiple DID Office Code Screening
Multiple DID Office Code Screening is an enhancement to the On-Net to Off-
Net Overflow capability of the NARS feature. This enhancement permits
network calls that undergo on-net to off-net conversion to terminate at any
Directory Number (DN) that has been defined in the LOC data block of
memory. This data block allows the definition of multiple office codes
(NXX) and/or multiple Directory Number (DN) ranges of the following
types:
• single office code/single Directory Number (DN) range
• single office code/multiple DN ranges
• multiple office codes/single DN range
• multiple office codes/multiple DN ranges
NARS Multiple DID Office Code Screening operates within the following
parameters:
• Only one Numbering Plan Area (NPA) per LOC is allowed.
• Ranges defined within a LOC must be unique. Overlapping or
duplication of ranges is not permitted.
• The number of digits must be the same in each Direct Inward Dialing
(DID) range.
• A maximum of 20 Direct Inward Dialing (DID) ranges may be defined
per location code.
BARS/NARS Off-Net Number Recognition
Off-Net Number Recognition is an enhancement to the Basic/Network
Alternate Route Selection (BARS/NARS) feature for ESN, and for the BARS
feature for standalone applications.
