Product Description

Qwest's retail telecommunication service, Private Branch Exchange (PBX) trunk service, is available for resale by Competitive Local Exchange Carriers (CLECs) to their end-users. Additional information about resale of Qwest's retail services can be found in Resale - Local Exchange Services - Business and Residence Plain Old Telephone Service (POTS) and Resale - General.

PBX trunk service provides analog or digital trunks to connect your end-user's PBX Customer Provided Equipment (CPE) telecommunications system equipment from your end-user's premises to the Qwest Central Office (CO). The trunks provided by Qwest are CO lines that terminate in a type of common equipment. Digital trunks are referred to as Digital Switched Services (DSS).

Your end-user's PBX CPE system equipment routes incoming, outgoing, and internal calls. The PBX system at your end-user's premises is what determines which line or trunk is available to make or receive a call.

PBX requires the following CPE components:

• Station Line - Internal line that connects the switching equipment of the PBX CPE to a station set or extension. Your end-user will typically have several internal station lines for each trunk connected to the CO. Internal calls do not utilize any of the trunks.
• Station Set- Basic telephone instrument equipped with function keys.
• Attendant Console - An expanded telephone or automated station is used for answering, managing, connecting and putting calls on hold.
• Centralized Processing Unit (CPU) - CPE that provides internal call routing when manual routing is not used.
• Guest Registers (optional with Hotel/Motel service) - records local calls made by guests (can also be located in the Central Office).
• Call Rating System (optional with Hotel/Motel service) equipment that times and rates 1+ long distance calls

The service is not available on a 1-way outgoing basis. Therefore, you must choose a combination of incoming-only and outgoing-only trunks or trunks with 2-way capabilities.

Types of CO Trunks:

• 1-way in, analog or digital - Receives incoming calls only.
• 1-way out, analog or digital - Handles outgoing calls only.
• 2-way, analog or digital - Provides for the flexibility of both incoming and outgoing calls over the same trunk.
• Safety Plus - A combination of 2-way analog trunk with Caller ID. This is not available with a Foreign Central Office or Foreign Exchange Service and the PBX system must be compatible with Caller ID Name and Number.
• Direct Inward Dialing (DID®) 1-way in or 2-way, analog or digital - Allows a caller to dial a seven-digit number to reach a specific PBX station.
• Data Trunks - Trunks that are digital only.
• Guest Trunk (for use with Hotel/Motel Service) - allows Hotel/Motel to charge for local calls.
• Toll Trunk (for use with Hotel/Motel service) - allows Hotel/Motel to rate and bill calls prior to guest check out.

• Measured rated trunks - Local calls by the minute.

Trunk Rating Categories:

• Flat rated - Service entitles the end-user to an unlimited number of calls within the local calling area.
• Message rated on a per call charge - Service for which charges based upon message units are made according to a measured amount of usage.
• Measured on a per minute charge - Service for which local usage charges will apply for outgoing calls completed on a local basis.

Optional Features

Amplified Voice Grade Circuit (VGA) is available in all states except Idaho. This option provides your end-user with improved transmission by limiting the decibel (dB) loss to no more than four dB (measured at 1005 Hertz (Hz)) from the local CO to the end-user's Network Interface Device (NID). A VGA trunk can have up to 8.5 dB loss.

Personal Lines provide direct access to or from the Qwest network and are not to be included in pooled facilities (access code dialing). These lines are personal lines that terminate on the PBX electronic sets and bypass the end-user's attendant. Personal Lines are available with loop start only.

Touchtone service applies to 1-way out only and 2-way trunks and is not available on DID.

Private Switch/Automatic Location Identification (PS/ALI) is available but is not available at a Resale discount (except in MN and WY) and must be separately purchased out of the Exchange Services Tariff for the particular State where it is located. PS/ALI requires a separate PS/ALI agreement in order to guarantee delivery of 911/E911 messaging. PS/ALI is offered separately from 911/Enhanced 911 (E911) services. For details on 911/E911 services and PS/ALI, see Access to Emergency Service (911/E911).

A complete list of standard features, feature descriptions, availability, pricing, and ordering information is available in the Resale - Features matrix. Some features have compatibility restrictions and cannot be used with DID trunks, contact your Qwest Service Manager with compatibility questions.

Traffic Data Report Service (TDRS) provides customers with a summary of traffic data on certain network facilities. For additional information contact your Qwest Service Manager.

Use of USOCs and Field Identifiers (FIDs) are described in the  Universal Service Order Codes (USOCs) and Field IDentifiers (FIDs) Overview.

The primary reason for ordering PBX service is for pooling access. Pooled access allows your end-user to have many more telephone stations than lines connected to the Qwest CO. PBX service operates on the premise that not all of the telephone sets will be in use at the same time. This method is the most efficient and cost effective way to maximize your end-user's telephone access.

Other features and benefits include:

Feature	Benefit
Call Monitoring	Provides the ability to restrict and monitor usage and receive internal call monitoring reports.
Off Premises Extensions	Provides the ability to connect PBX features to telephone sets in other offices.
Pooled Access	Allows a business to have more telephone stations than lines connect. Efficient use of telephones Cost effective way to maximize employee access.
Simplified Changes	Internal moves and extension number changes require only PBX reprogramming.

Pre-Ordering

General pre-ordering information is described in the Pre-Ordering Overview. Requirements for pre-ordering are described in Local Service Ordering Guidelines (LSOG) Pre-Order.

Ordering

It is important to understand the Resale - General procedures before ordering PBX.

General ordering activities are described in the Ordering Overview.

PBX trunks are available on a loop start or ground start basis. Loop start designs the cable pairs in such a manner that the tip conductor is grounded at the CO, whereas in ground start, the tip conductor is grounded at your end-user's premises.

Service requests should be placed using Interconnect Mediated Access (IMA)Extensible Markup Language (XML), IMA Graphical User Interface (GUI), or faxed to (888) 796-9089.

PBX service requests are placed using the following Local Service Ordering Guidelines (LSOG) forms:

• LSR
• End User (EU)
• Resale Service (RS)
• DID Resale Services (DRS)
• Directory Listing (DL), if applicable

Field entry requirements are described in the LSOG.

When selecting the type of product from the IMA GUI drop down menu for Resale Analog PBX trunks, use the following guidelines:

• Western Region (Washington, Oregon, N-Idaho) - Select designed trunks
• Eastern Region (Minnesota, Iowa, Nebraska, North and South Dakota) - Select PBX
• Central Region (Montana, Wyoming, S-Idaho, Colorado, Arizona, New Mexico, Utah) - Select designed trunks when VGA trunks are requested; Select PBX for non-VGA trunk requests.

DID trunk requests require use of the DRS form in place of the RS form. The REQTYP for Resale DID requests is NB.

Currently the TOS field does not allow you to state your preference for Measured, Message or Flat rated Class of Service nor does it allow you to state a preference for Foreign Exchange Service. In the interim, enter the appropriate USOCs in the Service Details section on the RS form.

The RSP contract identification number must be noted in the Variable Term Agreement (VTA) field on the LSR.

A sufficient number of trunks must be ordered to adequately handle the volume of incoming calls. If not, when all the DID trunks are busy, the calling party will receive a fast busy tone.

USOCs and FIDs are described in the Universal Service Order Codes (USOCs) and Field IDentifiers (FIDs) Overview.

A Design Layout Record (DLR) is available on designed trunks. The DLR request is described in the IMA XML Network Disclosure Document or in the IMA User's Guide.

The S2N USOC is required on all Out-only and 2-way DID trunk groups. The S2N USOC is associated with a telephone number that will be used for long distance billing and emergency 911 identification. Multiple trunk groups can share the same S2N telephone number.

This number must be a dialable number that can be called back by emergency services personnel and will be answered by your end-user. Whenever possible, your end-user's published number should be used for the S2N. When this is not possible, Qwest will accept a DID number,

When working with existing service, you should review the CSR to see if an S2N telephone number is assigned for each trunk group that requires one. If the S2N telephone number does not appear on the CSR, you must negotiate with your end-user to determine which number is to be used. Provide the information to Qwest by populating "S2N" in the Feature field and the telephone number in the Feature Detail field of the RS form.

When requesting new service, you should negotiate with your end-user which S2N telephone number assignment option they prefer; published number, other number in a DID range, or stand-alone DID. Populate the USOC "S2N" in the Feature field of the RS form and the chosen option in REMARKS, for example, "Use published number for S2N."

Qwest will provide the assigned S2N telephone number on the Firm Order Confirmation (FOC). It is your responsibility to communicate this telephone number to your end-user and/or their CPE vendor and ensure that they connect it to a telephone someone will answer when the number is called.

To order DID Digit Manipulation, include the following information in REMARKS field on the DRS form:

• DID Digit Manipulation
• instructions on how to program the new telephone number(s)
• PT3DM

e.g. REMARKS: DID Digit Manipulation request. Program telephone number 223-1264 for three digit out pulse PT3DM.
