Banded Message Rates

Chapter 5 Configuring BAMS for BAF Output

Call Area Provisioning Example

In Figure 5-1, many zones are not adjacent to other zones. The following commands set up MESSAGE rate call types for calls from zone 6 and zone 8, which are not adjacent to each other but are in the same LATA. In the example shown in Figure 5-1, many zone relationships of this type could occur.

prov-add:RATING-TYPE:ORGZONE=6,TRMZONE=8,RATETYPE="MESSAGE" prov-add:RATING-TYPE:ORGZONE=8,TRMZONE=6,RATETYPE="MESSAGE"

Configuring Trunk Groups for InterLATA Calls

Calls that cross LATA boundaries are normally considered toll calls, unless the zones are adjacent or an exception case is entered with the RATE-EXC tag ID. Because the default call type is interLATA (when either originating or terminating NPANXX is not found in the Zone Information table), the only provisioning required is on the ingress or egress trunk group.

For BAF billing records, the connectivity of the ingress or egress trunk determines the BAF direction of the calls. When configured properly, BAMS marks interLATA calls as INTERLATAORIGINATING or INTERLATATERMINATING. Because many telephone plan areas require only 7-digit dialing, the Trunk Group table is also used to populate default originating and terminating NPAs when fewer than 10 digits are received for the A number or the B number. Finally, each trunk group has multiple circuits, and the count of the number of circuits is captured in the Trunk Group table for different measurement calculations.

Although there are many trunk groups, in the example shown in Figure 5-1, we configure only a few trunk groups for Direct (to an end office) and a few trunk groups for Tandem (to an access tandem type office). All trunk groups must be provisioned in the table for proper BAMS operation. Only a small sample is shown here:

prov-add:TRUNKGRP:trunkgrp=123,connection="D",orgnpa=703,trmnpa=202,circuits=72 prov-add:TRUNKGRP:trunkgrp=124,connection="T",orgnpa=703,trmnpa=201,circuits=24 prov-add:TRUNKGRP:trunkgrp=223,connection="D",orgnpa=703,trmnpa=202,circuits=72 prov-add:TRUNKGRP:trunkgrp=227,connection="T",orgnpa=703,trmnpa=408,circuits=96

Configuring Adjacent Area Codes

Adjacent area codes present no problem to BAMS, because the key for the various lookup tables is based on the entire NPA-NXX (6-digit) string. Trunk groups must be provisioned, and, in the case of fewer than 10-digit dialing, they must indicate default originating and terminating NPAs.

Configuring IntraLATA Calls

Cases might occur where a billing design does not use FLAT, or designates calls for adjacent zones to something other than flat rate so that the downstream system can treat those calls differently. The following example shows configuration for intraLATA calls between zones within the same LATA:

prov-add:RATING-TYPE:orgzone=5,trmzone=4,ratetype="INTRALATA" prov-add:RATING-TYPE:orgzone=5,trmzone=6,ratetype="INTRALATA" prov-add:RATING-TYPE:orgzone=5,trmzone=6,ratetype="INTRALATA" prov-add:RATING-TYPE:orgzone=5,trmzone=6,ratetype="INTRALATA"
