Cross Connection for Access to UNEs
5.0 Cross Connections for Access to UNEs
The Telecommunications Act of 1996 specifically requires Local Exchange Carriers to provide network elements on an unbundled basis to any telecommunications carrier. However, the Competitive Local Exchange Carrier (CLEC) must perform the physical work associated with combining UNEs to establish a telecommunication service. The following section will discuss the three CLEC options for gaining access to UNEs:
- Combining Pacific Bell (PB)/Nevada Bell (NB) UNEs with other PB/NB UNEs
- Interconnecting PB/NB UNEs with the CLEC’s network
- Extending PB/NB UNEs to an Adjacent CLEC Location
5.1 Access to UNEs (3 Methods of Access) PB/NB to PB/NB
This subsection describes the methods under which PB/NB agrees to provide CLECs (both those CLECs which own facilities and those who operate without owning facilities) with access on an unbundled basis to loops, switch ports, and dedicated transport and the conditions under which PB/NB makes these methods available. These methods provide the CLEC access to multiple PB/NB UNE’s which the CLEC may then combine. The methods listed below provide the CLEC with access to UNEs without compromising the security, integrity, and reliability of the Public Switch Network, while minimizing potential service disruptions. PB/NB will provide one of the following five methods of nondiscriminatory access to loops, switch ports, and dedicated transport to allow a CLEC to combine PB/NB UNEs into telecommunications services.
- Method 1:
When a CLEC is physically collocated, PB/NB will extend UNEs that the CLEC intends to combine to their dedicated Point of Termination (POT) frame located in either the collocation cage or in the collocation common area.
- Method 2:
PB/NB will extend UNEs that the CLEC intends to combine to a shared UNE frame located in a mechanically secured common space within the central office building other than in the switchroom of the PB/NB central office or tandem office.
- Method 3:
PB/NB will extend UNEs that the CLEC intends to combine to a point outside the central office building or tandem office building, such as an outside plant (OSP) cabinet, provided it is a PB/NB building.
- Loops - applicable cross connects to the point of access for the purpose of combining a PB/NB loop with another PB/NB UNE are as follows:
- 2 wire analog loop to point of access
- 4 wire analog loop to point of access
- 2 wire digital loop to point of access
- 4 wire digital loop to point of access
- Unbundled Dedicated Transport (UDT) - applicable cross connects to the point of access for the purpose of combining PB/NB UDT with another PB/NB UNE is as follows:
- DS-1 to point of access
- DS-1 to point of access
- Switch ports - applicable cross connects to the point of access for the purpose of combining PB/NB switch ports with another PB/NB UNE are as follows:
- Analog Line Port to point of access
- Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) to point of access
- ISDN Primary Rate Interface (PRI) to point of access
- Methods 1 is only available to physically collocated CLECs.
- Methods 2 is available to both collocated and non-collocated CLECs.
- Methods 3 is subject to the availability of space and equipment.
- PB/NB will determine the availability of Method 2 based on space availability and equipment.
- The CLEC will provide all tools and materials required to place and remove the cross connects necessary to combine and to disconnect UNEs.
- The CLEC will be responsible for the initial testing and the sectionalization of facilities containing CLEC-installed cross connections.
- The CLEC will refer trouble sectionalized in the PB/NB UNE to PB/NB.

5.1.1 Three Access Methods
For the three access methods mentioned above, there are multiple cross connection options to each point of access.
Access to UNE's Restrictions:
Access to UNE's CLEC Requirements:
For a comprehensive list of CLEC requirements regarding access to UNEs, refer to Appendix UNE, 2.9 Access to Unbundled Network Elements.
The rates, terms, and conditions for the provisioning of these methods need to be determined through negotiations with the individual CLEC and will become part of the CLEC's Interconnection Agreement with PB/NB.
Rates for cross connects for the three methods of nondiscriminatory access to PB/NB UNEs described above are cost based. They include all wiring and terminations to extend the PB/NB UNEs to the point of access where the CLEC may combine them with other PB/NB UNEs. The five methods of access are being provided to enable CLECs to combine two different types of UNEs together.
For information about rates for the three methods, refer to Appendix Pricing of Generic Interconnection Agreement.

5.2 Network Component Services (NCS)
NCS is a discretionary offering where PB/NB performs the combining of certain UNEs on behalf of the CLEC for the purpose of the CLEC providing an end to end telecommunications service to end users. The CLEC will still be required to order with specificity since PB/NB will not provide any UNE 'packages' or 'combinations' up front. PB/NB will combine, on a case by case basis, selected UNEs for the CLEC. NCS will be provided by PB/NB at market based prices and is neither subject to true-up nor arbitration. All rates and charges associated with individual UNEs that are being combined are applicable in addition to the NCS charges.

5.3 Physical and Virtual Collocation - Access to UNEs - PB/NB to CLEC
PB/NB UNEs may be interconnected to the CLEC network. Physical collocation and virtual collocation are provisioned for the purpose of CLEC interconnection with the PB/NB network.
There are multiple cross connect options PB/NB offers to CLECs who are either physically or virtually collocated to provide telecommunications services:
- Loops - applicable cross connects for the purpose of connecting a PB/NB UNE to a CLEC's collocated facilities are as follows:
- 2 wire analog loop to point of collocation
- 4 wire analog loop to point of collocation
- 2 wire digital loop to point of collocation
- 4 wire digital loop to point of collocation
- Dedicated Transport - applicable cross connects for the purpose of connecting a PB/NB UNE to a CLEC’s collocated facilities are as follows:
- DS-1 to collocation
- DS-3 to collocation
- OC3 to collocation
- OC12 to collocation
- OC48 to collocation
- Switch ports - applicable cross connects for the purpose of connecting a PB/NB UNE to a CLEC’s collocated facilities are as follows:
- Analog Line Port to collocation
- ISDN BRI to collocation
- ISDN PRI to collocation
- Analog DID to collocation
For more comprehensive information regarding PB/NB cross connects, refer to Appendix UNE, 11.0 Cross Connects.
For more information about physical and virtual collocation, refer to Collocation.

5.4 Adjacent Location Method for Accessing UNEs Description
This method is an additional method besides collocation and Access to UNEs (for the purpose of combining Pacific UNEs) for the CLEC. The Adjacent Location Method for Accessing UNEs is not Collocation or Access to UNEs.
This method extends a PB UNE (loop, switch port, and/or dedicated transport) from the Pacific Bell Main Distributing Frame (MDF), which is, then cross connected to a PB Intermediate Distribution Frame (IDF) via the appropriate cross connect. The PB UNE is then extended to the CLEC Location) via a CLEC terminated cable on the IDF.
The extension of Pacific Bell UNEs is accomplished via a copper cable, provided by the CLEC, which they provide to Pacific at the last manhole. The CLEC is required to provide enough slack for Pacific to pull the cable into the central office and terminate it on the Intermediate Distribution Frame (IDF).
- Individual Case Basis (ICB) costs for terminating the CLEC cable
on the IDF. The ICB will include the cost of adding a new, or additions to, the PB IDF. This cost may also include the addition of/to and IDF.
- The UNE rate, of the UNE being extended based on the Interconnection Agreement, and
- The appropriate cross connect rate.
- Loops:
- 2 wire analog
- 4 wire analog
- 2 wire digital
- 4 wire digital
- Switch Ports:
- Analog Line Port
- ISDN Basic Rate Interface
- ISDN Primary Rate Interface
- Dedicated Transport:
- DS-1
- DS-3
Pacific allows two cable entrances into the office per CUSTOMER. This allows for growth or provides for a diverse path. It is technically inappropriate, in order to maximize the use of the ducts, to pull less than a 600 pair cable into the central office for termination on the IDF. This is the same requirement that Pacific uses in the design of our cables. Therefore, the CLEC is limited to cables of 600 pairs or greater.
PB/NB cannot guarantee the transmission the CLECs service to the CLECs end users.
The customer is responsible for Spectrum Management and is aware that pairs may not be ADSL capable.
The customer is responsible for providing building entrance and premises conduit, adequate terminal room and/or backboard space, AC electrical power and all cabling on the customer’s side of the demark.
The installation interval is dependent upon electrical power and conduit being available 4 weeks prior to the ready for service date.
The customer will provide the excess cable length necessary to reach the Pacific Intermediate Distribution Frame (IDF) in the Pacific Bell central office where customer requests connection.
The customer will obtain all necessary rights of way, easements, and other third party
Pacific cannot guarantee the CLEC service to the end user for this arrangement.
5.4.1 Adjacent Location Method for Accessing UNEs Pricing
The CLEC will incur three costs when ordering this method:
5.4.2 Adjacent Location Method for Accessing UNEs Cross Connects
The cross connect is the media between the Pacific distribution frame and the CLECs point of access on the IDF.
The Following Cross Connects are applicable (to point of access):
5.4.3 Adjacent Location Method for Accessing UNES Restrictions
5.4.4 Adjacent Location Method for Accessing UNEs CLEC Requirements
Rates for cross connects for this method described above are cost based. They include all wiring and terminations to extend the PB/NB UNEs to the point of access (IDF) where the CLEC cable is terminated. Cross Connects not listed will be ICB priced.
