NDA-24311, Issue 1
L-31 Least Cost Routing - 3/6-Digit - PRI
Service Conditions (cont’d)
6. In certain cases, three- and six-digit translation provides sufficient information for identification of the
service area. Up to 256 separate Outgoing Routing Patterns are provided for this.
7. Up to eight trunk routes can be in each Outgoing Routing Pattern.
8. STATION MESSAGE DETAIL RECORDING (SMDR) [S-10] may be used in conjunction with LEAST
COST ROUTING - 3/6-DIGIT - PRI. The route selected by the switch will be recorded by the STATION
MESSAGE DETAIL RECORDING (SMDR) [S-10] unit.
9. Tie Lines can be included in route patterns.
10. Application of NXX patterns provides for inclusion of multiple common carriers serving different areas.
11. When a tie trunk requiring an off-net connection to the local central office is included as a route option,
the NEAX2400 IPX can provide a 2.8 second prepause before sending out the selecting signal.
12. Senders (dial pulse or tone) are provided with this feature for dialing.
13. Pre-translation capability minimizes waiting time after dialing. After enough digits are collected to
determine a route, the system starts outpulsing before the station completes dialing the entire called
number.
14. When LEAST COST ROUTING - 3/6-DIGIT - PRI is provided, the Attendant cannot pass dial tone to a
station. The desired number must be dialed by the Attendant.
15. Stations having different Route Restriction Classes, but using the same LEAST COST ROUTING - 3/6-
DIGIT - PRI pattern, can be denied access to the last choice trunk route(s) in that pattern. Route Restriction
Classes can be set up so that a station dialing an area code can use WATS, FX, and DDD; or only the
WATS line, if such an arrangement is desired. This is a form of forced Least Cost Routing.
16. NXX patterns can be programmed to restrict all stations in the system from completing calls to specific
NXX numbers over FX trunks.
17. The system includes the ability to detect a dialed DDD number and compare it with a DDD list table to
determine if the call is directed to a facility served by the trunk network. If the dialed number is found in
the DDD list table, a translation is provided to the seven-digit, on-net number (ABC-XXXX) served by
the tie trunk. This allows an expensive public network dialed number to be trapped and automatically be
diverted to an available leased facility. If a Tie Line is not available, the call is routed as dialed.
18. The NEAX2400 IPX is capable of converting a maximum of 24 receiving digits into a required 24-digit
number entirely. An interdigit pause can be inserted whenever necessary. This provides for an extremely
flexible numbering plan for a complex network.
19. CALL-BY-CALL SERVICE SELECTION [C-105] is available on a trunk provisioning basis.
