³ Reason for Change/Addition: Clarification of interactions between CNA recording and SSP Toll Free/AIN Toll Free AMA recording

Proposed revised requirements for the interaction between the CNA recording option on incoming trunk groups and SSP Toll Free/AIN Toll Free AMA recording performed at the CNA recording switch. These requirements are the result of discussion and consensus of the Illinois Number Portability Workshop - Billing & Rating sub-committee conference call on January 24, 1997. All comments and suggested changes should be forwarded to Arnette Schultz of Lucent Technologies (a.p.schultz@lucent.com) by Friday, February 7, 1997. If no comments, or only editorial comments, are received the revised requirements will be forwarded as "approved" to the ICC Number Portability GR author for inclusion in the next issue (1.05).

<REQ-IL-GR-1315V1.05>

When a call is received over a trunk group with the "connecting network access recording" option on, and the incoming call results in an SSP Toll Free or AIN Toll Free query (e.g. called 800/888 number) the Connecting Network Access record shall be generated as described in REQ-1310 in addition to any AMA records generated for the Toll Free query. However, in this case the LNP module shall be appended to the Toll Free AMA record, as the Toll Free AMA record is that applicable to the "pre-LNP query" call leg. Additionally, the terminating number field of the Toll Free AMA record, if any, generated shall contain the dialed Toll Free number (e.g. 800/888 number).

Note: this requirement applies ONLY to the case where the incoming trunk group is marked with the option for CNA recording for all calls. Refer to REQ-1320 for procedures involving "limited recording of connecting network access".

<END of REQ-1315>

<OPT-IL-GR-1320V1.05>

• When the call incoming to the switch is received over a trunk group with the "limited recording of connecting network access " option on, the Connecting Network Access record shall be generated as described in REQ-1310 only when the recording switch performs a LNP query for the incoming call, with the following two exceptions: This "limited recording of connecting network access" option shall NOT apply when a switch performs an LNP query following call forwarding or other forms of call re-direction including re-direction via an AIN trigger (i.e. no CNA record should be generated when the called party number is changed via call forwarding, call re-direction, or AIN trigger prior to the switch performing an LNP query.)
• The "limited recording of connecting network access" option shall NOT apply when a switch performs an AIN Toll Free or SSP Number Services (e.g. 800/888) query prior to performing the LNP query (note: in this case the LNP module will be appended to any AMA record made for the AIN or SSP query).

Carrier Connect Time for this "limited recording of connecting network access" shall be recorded as the time of incoming trunk seizure or receipt of an SS7 IAM in accordance with existing industry procedures for IC/INC Carrier Connect Time determination.

The "limited recording of connecting network access" option is defined in section 4.5.1 - Service Changes.
