Dedicated Transit Service (DTS) can be ordered by one CLEC to connect its collocation arrangement to another CLEC's collocation arrangement or to another collocation arrangement of its own in the same Verizon central office. DTS is only available provided that the collocated equipment of both collocators is also used for interconnection with Verizon or access to unbundled network elements. Such connections may be physical arrangement to physical arrangement, physical to virtual, virtual to physical, or virtual to virtual. DTS is ordered via an Access Service Request (ASR), with the initiating CLEC becoming the ordering, provisioning, maintenance and billing customer of record. Split billing for DTS is not permitted.

The arrangement ordered to is reflected only as the terminating end of the services (i.e., an end user-like location). Alternatively, a CLEC may order DTS to connect two of its own virtual arrangements in the same Verizon premises, in what is known as a Virtual Collocation Cascading Arrangement (VCA). In this case, the CLEC requests the two virtual collocation arrangements in cascading fashion on the virtual collocation application as a part of the virtual arrangement configuration. An ASR should not be issued by the CLEC. Verizon installs VCA at the time of the virtual collocation arrangement installation.

A CLEC may connect one collocation arrangement to another CLEC's collocation arrangement by ordering (only) dedicated circuits through Verizon distributing frames, joining their collocation arrangement to that of another CLEC, or using existing circuit architectures.

DTS is available via Voice Grade (VG), DS1, DS3, OC3, and Dark Fiber in the following configurations:

• Physical Collocation to Physical Collocation arrangements
• Physical Collocation to Virtual Collocation arrangements
• Virtual Collocation to Virtual Collocation arrangements

Requests for lit fiber cross connects between two collocation arrangements will be handled on a case-by-case basis.

Existing NC/NCI codes for VG, DS1, DS3, and Dark Fiber are used, as are existing circuit nomenclature, circuit identification (CLS format), and Circuit Location Addresses (CKL format) which include POI/XPOI information to designate specific circuit termination locations (i.e., the CLLI for the collocation arrangement). Visit Verizon Business Rules for Non LSOG Specific information.

Overall designs for DTS are made based on existing engineering standards and practices and existing private line processes. DTS may require cooperative testing with both CLECs, or between Verizon and the CLEC in the case of VCA, to isolate and resolve trouble conditions.

CLECs are no longer permitted to directly cable facilities ("cable over the wall") between collocation arrangements in the same room. Dedicated Cable Support, which is described below is only furnished to CLECs with existing DCS arrangements. Additions, rearrangements and moves are not permitted. The two collocation arrangements must be co-terminous (i.e., both must be located within the same central office).

For some state DTS options, and all transmission levels (VG, DS1, DS3, and Dark Fiber), each DTS service has one transmission level specific recurring rate element applied per collocation arrangement. Since interoffice transport is not used, there is no mileage sensitive transport element.

The recurring rate is for maintenance of the cables and terminations between the collocation arrangements and the digital cross-connect/fiber distributing frames, along with the appropriate cost of the distribution network. This recurring rate is considered a generic Service Access Charge (SAC), Interconnection Access Charge (IAC), or cross connect. The same SAC/IAC USOCs and rates that are applied to connections of other UNEs apply in this instance. In other states, the SAC/IAC and cross connects are billed to the collocator when the collocation arrangement is completed. The application of rates are defined in the applicable tariffs.

Non-recurring charges are for expenses associated with circuit provisioning, central office wiring, and service orders. The circuit provisioning charge includes the costs for circuit engineering (Circuit Provisioning Center), circuit wiring and turn-up (central office and control office), etc. The service order charge includes the costs for order placement and issuance. The same service order charge is applied to all transmission levels. There are, however, distinct provisioning charges for VG, DS1, DS3, and Dark Fiber transmission speeds.

Pricing and applicable USOCs are pursuant to applicable tariffs, SGATs or interconnection agreements and may vary accordingly.

The interval for DTS is negotiated.
