2 UNBUNDLED ELEMENTS Sheet INTERCONNECTION The provisions in this section apply when unbundled elements are used in conjunction with interconnection to the Qwest network for the exchange of traffic. Interconnection is the linking of Qwest's and the Carrier's networks for the mutual exchange of traffic and for the Carrier's access to unbundled network elements. Interconnection does not include the transport and termination of traffic. Interconnection is provided by entrance facilities or Mid-Span Meet arrangements. Qwest will provide interconnection at the lineside of the local switch, the trunkside of the local switch, trunk interconnection points of the tandem switch, and central office cross-connect points. 1.2 ACCESS TO UNBUNDLED ELEMENTS A. Qwest will provide the following unbundled network elements in the following categories: Local Loops Cross Connect Facilities Switch Port Interconnection Network Elements Switching Interoffice Transport Switching Features Channel Performance Ancillary Services B. Unbundled Loops 1. An unbundled local loop establishes a transmission path between the Qwest distribution frame (or equivalent) and Qwest s network interface device (NID). An unbundled loop is also called a Network Access Channel (NAC). Descriptions of the types offered as unbundled network elements are set forth in E., following. For existing loops, the inside wire connection to the NID will remain intact. 2. Basic unbundled loops are available as a two-wire or four-wire, point-to-point configuration suitable for local exchange type services within the analog voice frequency range of 300 to 3000 Hz. For the two-wire configuration, the Carrier is required to specify loop start or ground start option. The actual loop facilities that provide this service may utilize various technologies or combinations of technologies. Basic unbundled loops will provide an analog facility to the Carrier.

3 UNBUNDLED ELEMENTS Sheet ACCESS TO UNBUNDLED ELEMENTS B. Unbundled Loops (Cont'd) 3. For unbundled two-wire and four-wire loops, installation is available as follows: a. Basic Installation Installation of an unbundled loop requires wiring a cable pair to the requested position (e.g., CFA) at the Carrier s presence in the central office. The work is done at a time determined by Qwest on the agreed to due date. b. Basic Installation with Conformance Testing Results Provided Installation of an unbundled loop requires wiring a cable pair to the requested position (e.g., CFA) at the Carrier s presence in the central office. The work is done at a time determined by Qwest on the agreed to due date. The loop installation will include specific testing (e.g., 3 tone slope, C-message noise, cable free of electrical fault, 1004 Hz loss, less than or equal to 8.5 db). c. Coordinated Installation with Cooperative Testing Installation of an unbundled loop requires wiring a cable pair to the requested position (e.g., CFA) at the Carrier s presence in the central office. The loop installation will include specific testing (e.g., 3 tone slope, C-message noise, cable free of electrical fault, 1004 Hz loss, less than or equal to 8.5 db). The installation will take place at a designated time (within the normal Monday thru Friday 8 a.m. to 5 p.m. work day) previously agreed to by Qwest and the Carrier. If the Carrier requests installation outside of normal business hours, additional labor charges will apply. d. Coordinated Installation without Cooperative Testing Installation of an unbundled loop requires wiring a cable pair to the requested position (e.g., CFA) at the Carrier s presence in the central office. The installation will take place at a designated time (within the normal Monday thru Friday 8 a.m. to 5 p.m. work day) previously agreed to by Qwest and the Carrier. If the Carrier requests installation outside of normal business hours, additional labor charges will apply. This option is available only when converting an existing Qwest end user to another Carrier or when another Carrier s end user changes carriers. 4. For DS1, Primary Rate ISDN Capable and DS3 unbundled loops, installation of service is available with testing results provided to the Carrier.

When an 8XX call is originated by a Carrier s end user, the Carrier s SSP (SS7 equipped end office) will send a 8XX query to the Qwest 8XX Service Control Point (SCP) through the Qwest Signaling Transfer Point (STP). The Qwest SCP will perform the Carrier Identification Function based on the dialed digits to determine the toll carrier trunk group to which the call should be routed in accordance with the SMS/800 information residing in the Qwest SCP. The SCP will transmit the results of the Carrier Identification Function back to the Carrier s SSP through the Qwest STP. The results of the Carrier Identification Function will be the Carrier Identification Code (CIC) and/or the vertical features associated with the 8XX number.
