Least Cost Routing (LCR)
The U NIVERGE NEAX
2000 IPS provides extensive Least Cost Routing capabilities. LCR
allows the U NIVERGE NEAX
2000 IPS to be programmed to route outgoing calls over the most
economical facility (WATS, FX, and DDD), based on the area code and office code dialed. In
the case of Specialized Common Carriers, associated NXX patterns can be screened out via
6-digit Toll Restriction if the dialed number is not within the designated service area of that
SCC.
The U NIVERGE NEAX
2000 IPS system provides one of the most flexible route selection
capabilities of any system on the market today. While many systems can add and/or delete
digits on incoming calls, it is the capability of what can be done on outgoing calls that make the
U NIVERGE NEAX
2000 IPS such a powerful and cost effective system.
When multiple routes are to be used for an outgoing call, the system is programmed with route
order priority (RA). Priority 1 usually being the most cost effective route for the call being
made. Up to eight route choices can be assigned for a call. These choices would be put into an
Outgoing Route Pattern (OPR). The system allows for up to 64 different OPRs to be
constructed.
For true cost effective use of outgoing dialing, it may be desired to change the outgoing route
selection during specific times when certain carriers may offer cheaper rates. These OPRs can
be assigned using one of eight different Time of Day Patterns (TDPTN). In TDPTN data, you
assign what pattern is used at what time of day. You then assign the Time Pattern in the OPR
data.
Outgoing calls made using the Least Cost Routing (LCR) can have up to 24 digits added to the
number dialed. In OPR data, the system will ask if and how many digits are to be deleted from
the number dialed. It will then ask if any digits are to be added, and if so, what are the digits to
add in front.
Besides the flexibility of getting a call out of the system, restriction controls make this system
one of the best. There are various types of call restrictions that can be made. Some of them
are as follows:
Six Digit Least Cost Routing
This allows you to restrict specific area code(s) from going out a specific route, even though
the route is included in the OPR constructed. This table lets you choose the TDPTN, the OPR,
the RA, and the area code. Then, designate whether the area code is allowed or not.
Route Restriction Class (RSC)
There are 8 different restriction classes that can be created to allow, deny, or toll restrict
certain users from dialing certain numbers. An RSC is assigned to the stations. The RSC table
is then constructed on a per route basis to determine whether a number dialed from a station
in a specific RSC is to be allowed, denied, or toll restricted.
