V.2.2 Access Toll Connecting Trunks shall be used solely for the transmission and routing of Exchange Access, nontranslated 800 and 976 traffic to allow Requesting Carrier’s Customers to connect to or be connected to the interexchange trunks of any Interexchange Carrier which is connected to an Ameritech access Tandem. V.2.3 The Access Toll Connecting Trunks shall be two-way trunks connecting an End Office Switch that Requesting Carrier utilizes to provide Telephone Exchange Service and Switched Exchange Access Service in a given LATA to an access Tandem Switch Ameritech utilizes to provide Exchange Access in such LATA. V.2.4 IntraLATA toll free traffic (e.g., 800) shall be routed over Ameritech’s Access Toll Connecting Trunks. Ameritech will send Requesting Carrier a Carrier Identification Code of 110 to identify the IntraLATA call as toll free call. Requesting Carrier shall generate and send Ameritech on a daily basis an 010125 access record. In return, Ameritech will send Requesting Carrier on a daily basis an 110125 access record for billing the query function according to Requesting Carrier’s tariff. This information should be included on the summary record (010125) sent to Ameritech by Requesting Carrier.
