Qwest's retail telecommunications service, ISDN PRI 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 General.
ISDN PRI is known by several interchangeable terms: Primary Rate Service (PRS), ISDN PRI and ISDN PRS.
ISDN PRI is a switched digital service that transfers information over the public switched telephone network via a 4-wire physical network configuration, with a full duplex transmission path between either your end-user's Customer Provided Equipment (CPE) an Interexchange Carrier (IXC) Point of Presence (POP) or your Collocation space. Deployment of ISDN PRI requires that the end-user has ISDN-compatible Customer Provided Equipment (CPE). ISDN PRI is provided on a Digital Service Level 1 (DS1) facility that is multiplexed into 24 channels in various configurations of In-only, Out-only and 2-way dialing. The basic service consists of 23 B Channels and a D Channel with a transmission rate of 1.544 Megabits per second (Mbps). Each B Channel carries user information and the D-Channel is used for signaling. The channel configuration is commonly referred to as 23B+D.
ISDN PRI service is provisioned from the trunk side of the switch. No custom calling features are available because custom calling features are designed to work on the line side of the switch.
The B channels can be used to transmit:
The following voice type services can ride over a B channel:
ISDN PRI is comprised of the combination of the following elements:
Facility:
Trunks:
ISDN PRI is offered with the following standard features (may vary with state tariffs):
There are four options for trunk connections:
ISDN PRI is available in two translation protocol types, Custom and National ISDN-2 (NI-2). Both Custom and National protocol types are available in 5ESS® and DMS™-100 switch types. In a 5ESS switch, Custom protocol ISDN PRI uses a 5ESS proprietary protocol as opposed to NI-2 that is not tied to a switch-specific protocol.
The transmission path (DS1) provides 24 64 Kbps channels. With Custom protocol ISDN PRI, up to 23 of the channels may be used as 64 Kbps B channels. The 24th channel must be configured as a D channel, which will carry the signaling. In a 5ESS Custom arrangement, every facility must have its own D channel and in a DMS-100 Custom arrangement the facility can be configured with a D channel, back-up D channel or without a D channel.
With the NI-2 protocol, you have more flexibility when purchasing multiple ISDN PRI. The first ISDN PRI must be configured as a 23B+D. The additional ISDN PRI may be configured as 23B+Back-up D or 24B. One D channel can do the signaling for up to 479 B channels (20 facilities) if they all terminate at the same destination.
NI-2 provides the option of a back-up D channel. The back-up D is used if the Primary D channel fails. In case of failure, all active calls are dropped during the switch over to the back-up D channel. Once the back-up D channel is in service, the B channels will be restored and new calls can be originated or received. Calls dropped during the switch over will not be reestablished.
ISDN PRI is available in the following configurations:
PRI utilization for Voice Over Internet Provider (VoIP) Providers
PRI service is available for resale by CLECs to their end-users to be used as network infrastructure for Information Service Providers (ISP), including VoIP. The PRI may terminate at an IXC POP. Additional components of the service include:
Certification is required and will be part of the signed Individual Case Basis (ICB) that the service will only be used to provide "information services" as defined in 47 U.S.C. ยง153 (20). The customer must certify the PRS regardless if termination occurs at an IXC POP or not.
Companies certifying that the PRS will be used exclusively for VoIP will be allowed to:
Contact your Qwest Sales Executive for additional information.
ISDN PRI service is available throughout Qwest's 14-state local service territory but it is not available in all central offices (CO). COs that have Basic Rate ISDN (2B+D) may not have ISDN PRI capability.
ISDN PRI may terminate at an IXC POP it is limited to data service for Internet access only, terminating on the Internet by an Internet Service Provider (ISP) who is your end-user. Voice Service may not terminate at the IXC POP.
In remote central offices where ISDN PRI is not deployed, but can be provided from the host switch, the service will be provided with numbers from the remote (serving) central office. The service will be offered on a bulk rated basis only. If you request telephone numbers from the host switch, you will be billed interoffice mileage charges.
ISDN PRI service is offered on a month-to-month or contract basis.
ISDN PRI service may be provided via a fiber optic facility. Construction charges, as specified in your Interconnection and/or Resale contract and/or the state Tariffs/Catalogs/Price Lists may apply.
End-user ISDN CPE is required in order to utilize this service. CPE can be in the form of Terminal Adapters or ISDN terminal equipment (telephones). Configuration and Capability Package Ordering Codes are available from Telcordia 1-800-521-CORE, or check with your CPE Vendor/Manufacturer.
The ISDN PRI DS1 signals at the end-user's CPE will be timed from the Central Office Timing Supply or directly from the Qwest CO switch. All new DS1 signals must be Network Timed.
DID Digit Manipulation allows the expansion of a number range to include numbers that do not fit the current end-user's CPE (PBX) programmed dialing pattern. Additional information can be found in the state specific Tariffs/Catalogs/Price Lists.
ISDN PRI service is available in:
ISDN PRI service is not available for use by Commercial Mobile Radio Carriers (CMRS), Private Mobile Radio Carriers (PMRS), or Interexchange Carriers (IXC) in the provisioning of services to their end-users.
The following products, features and services are not allowed to traverse an ISDN PRI DS1 facility:
Due to emergency 911 concerns, In-only trunks are the only trunk type available with Resale ISDN PRI services that terminate in your collocation space, i.e., outgoing calls to 911 emergency services would appear to originate from the collocation space address, and not from the end-user address.
Technical recommendations, including Network Channel/Network Channel Interface (NC/NCITM) codes, are specified in Technical Publication 77400 Primary Rate ISDN Service.
Termination Liability Charges (TLA) may apply to convert an end-user to ISDN PRI and if applicable, are billed to the end-user on their final bill.
Nonrecurring charges apply when establishing, changing, or converting existing service to ISDN PRI service.
You may change features, Primary Interexchange Carrier (PIC), listings, and/or telephone numbers at the time of conversion, applicable charges will apply.
Mileage charges may apply for Foreign Central Offices (FCO) or Foreign Exchange Services.
Monthly and/or recurring charges may apply for some features.
Bulk pricing enables CLECS and Qwest Retail customers to obtain
lower rates for ISDN PRI service by signing a Variable Term Agreement
(VTA). A single bulk rate, for the trunks and facility, is paid
for the contracted term. All charges are billed to the facility
account and not the trunk account.
To order bulk pricing, contact your Qwest
Sales Executive for a contract number and bulk pricing USOCs,
this information will need to be entered on your service request.
When the contract number is entered in the VTA field on the LSR
facility request, it constitutes signing and agreeing to the terms
of the contract. A unique contract number must be obtained for each
of your end-users, however, multiple facilities and their associated
trunks may be on the same contract. Bulk pricing USOCs must be entered
in the REMARKS on the RPL form and in the FEATURE field on the RS
form.
The rate elements for ISDN PRI include:

ISDN PRI service applications
If you are a new CLEC and are ready to do business with Qwest, please view Getting Started as a Facility-Based CLEC or Getting Started for Resellers.
If you are an existing CLEC wishing to amend your Interconnection Agreement or your New Customer Questionnaire, you can find additional information in the Interconnection Agreement.
General pre-ordering information is located in the Pre-Ordering Overview.
ISDN PRI pre-qualification is a two step process to determine the ISDN PRI service is available to your end-user and there are facilities available to provision the service. Qwest strongly suggests that you complete the ISDN PRI pre-qualification process prior to ordering ISDN PRI.
Step one
Verify the availability in the end-user's CO by referring to the Network Disclosures. Select the state for the end-user's CO location, then select the end's users CO. If the ISDN PRI DATE column is populated with "Deployed", ISDN PRI is available.
Step two
Verify if facilities are available to provision the ISDN PRI T1 at the end-user's address, use the Interconnect Mediated Access (IMA) User's Guide. Follow the instructions for a High-Capacity Facility check. In completing the High-Capacity Facility check, use the Class of Service and USOC specific to the product for which you are checking the facility.
If the PRI T1 (DS1) will ride a higher facility (DS3), a facility check is not performed.
Or if you use IMA XML, select the release you would like to execute the query in and scroll to the chapter that is titled "Facility Availability Transaction" and follow the instructions.
The following activities may need to be performed by you in preparation for the issuance of the ordering request:
New ISDN PRI telephone numbers can not be reserved using Interconnect Mediated Access (IMA). Qwest will return telephone numbers to you on the Firm Order Confirmation (FOC). If your end-user wants to convert an existing non-ISDN telephone number to Resale ISDN PRI, check with your Qwest Service Manager to see if the telephone number can be converted. Availability of ISDN PRI in the end-user's serving office does not guarantee that the prefix will be compatible.
There are at least two CSRs for each ISDN PRI service configuration, the T1 facility CSR, and one or more trunk CSRs for the services riding the T1. When converting these products, both the facility and the trunks are to be converted and you must review both the facility and the trunk CSRs. Based on the type of request, subsequent changes may also require the review of both CSRs.
The trunk CSR has a standard telephone number as the account telephone number and is available in IMA via the standard pre-order CSR request function. The facility CSR has a private line account number, also known as a Mechanized Account Number (MAN) or Special Billing Number (SBN). If you know this account number you can also obtain the facility CSR via IMA.
If you don't have the account number, you may find it cross-referenced on the trunk CSR. The cross-reference may appear:
If the facility account number is not referenced on the trunk CSR, locate the Common Language Facility Identification (CLFITM). The CLFI appears on the trunk CSR after each trunk USOC, following the CFA (Connecting Facility Assignment) FID, and identifies the name of the facility the trunk rides, as well as the channel it occupies, e.g., CFA 101 T1ZF 23 CLLITM CLLI. Qwest can use the CLFI to obtain the facility account number for you.
If you are unable to locate the facility CSR, call the Qwest Customer Service Inquiry and Education (CSIE)Interconnect and select the Centrex and Complex Resale option to reach the appropriate workgroup.
When contacting the Qwest ISC, be prepared to provide:
Depending on your needs, Qwest can:
It is important to understand the Resale General Procedures before ordering Resale ISDN PRI.
General ordering activities are identified in the Ordering Overview.
Disclosure Information and other LSR instructions are available on the web.
Qwest will provision ISDN PRI according to the standard intervals for the equivalent retail service. Service interval guidelines are found in the Service Interval Guide (SIG).
You may order new ISDN PRI service or convert existing retail or resale ISDN PRI.
At the time of conversion, you may include changes to features, PIC, Local Primary Interexchange Carrier (LPIC), listings, and telephone numbers.
ISDN PRI orders are completed following the Local Service Ordering Guidelines (LSOG) along with the appropriate NC/NCI codes. Orders should be placed using Interconnect Mediated Access (IMA) Extensible Markup Language (XML), IMA Graphical User Interface (GUI), or faxed to (888) 796-9089.
A new installation (ACT N) of ISDN PRI service requires at least two local service requests. One local service request for the facility and one or more local service requests for the trunk. The local service requests must be issued at the same time and related to each other using the RPON field.
The facility request requires the following LSOG forms:
The trunk request requires the following LSOG forms:
The following checklists identify unique ordering information for the ISDN PRI facility and trunk requests, more detailed information on the order entries follows the checklists.

| T1KBJ | PT31C (one for each Out-only trunk), DR5 (one for each derived B Channel), ND2 (one for each trunk) |
If the UAS option is required, NWO++ replaces the PT3++ USOC. The DMS-100 switch with dedicated trunking arrangements and the DS1 facility must have the same trunk types. They cannot be mixed. Circuit Switched Data (data only) cannot be mixed with voice trunking arrangements on the same facility.
The S2N USOC is required on all Out-only and 2-way DID PRI trunk groups. Multiple trunk groups can share the same S2N. The S2N is assigned a telephone number, which will be used for long distance billing and for 911 identification. This number must be a dialable number which can be called back by emergency services personnel and which will be answered by the end-user. The end-user's published number should be used for the S2N is not possible, Qwest can use a DID, POTS, trunk or stand alone DID number on the account.
With existing service, review the CSR to ensure an S2N is assigned for each applicable trunk group. If not, negotiate with the end-user to determine which telephone number they want to use and indicate it on the RS form in the FEATURE and FEATURE fields. Populate "S2N" in the FEATURE and the telephone number in the FEATURE DETAILS.
When requesting a new installation (ACT N), negotiate with the end-user which published or DID number will used for each applicable trunk. Populate FEATURE field of the RS form with the USOC S2N and include a 'Y' in the MANUAL IND field along with an entry in REMARKS field, e.g., "Use published telephone number for S2N". Qwest will include the assigned S2N telephone number on the Firm Order Confirmation (FOC). It is your responsibility to communicate the S2N telephone number the end-user and/or their CPE vendor and in order for the CPE to direct calls to the appropriate telephone set.
When requesting new service, you should negotiate with the end-user which option, published number, other number in a DID range, stand-alone DID that they need. Populate the USOC S2N in the FEATURE field of the RS form and the chosen option in REMARKS, e.g., "Use published number for S2N". Qwest will indicate on the FOC the number assigned for the S2N. It is your responsibility to make sure this number is communicated to the end-user and/or their CPE vendor and is directed by the CPE to a telephone set that will be answered.
Hunting features are available with ISDN PRI and vary depending on the switch type.
Glare Resolution is the ability of a system to ensure that if a trunk is seized by both ends simultaneously, one caller is given priority and the other call is switched to another trunk. Glare occurs when both ends of a telephone line or trunk are seized at the same time for different purposes or by different users. If the CPE is set to hunt, the Central Office should be set up just the opposite to minimize glare. In the REMARKS field of the LSR form, you must enter whom "Yields to Glare". If you enter "Qwest Yields to Glare", your end-user's call is given priority. If you enter "(Your Name) Yields to Glare", the Qwest call is given priority.
Include a 'Y' in the MANUAL IND field and the Hunting Type in the REMARKS section of the LSR form for the trunk request for new installations (ACT N), changes (ACT C), and outside move (ACT T) requests. The following tables identify the types of hunting available for each switch type.
| 5ESS Switch Type | Description |
| BGUCD | Backward Circular Sequential - The start hunt member is the last selected member -1. Hunting then continues through the trunk members in a backward direction using circular hunting to the lowest member, then starting over at the highest member. The hunt continues in this manner until an idle is found or all the members are found busy. |
| Forward | A trunk is selected starting with the first trunk in the group in ascending order. |
| GUCD | Forward Circular Sequential Hunt - The hunt member is the last selected member +1. Hunting continues through the trunk members in a forward direction using circular hunting to the highest member, then starting over at the lowest member. The hunt continues until an idle member is found or all members are found busy. |
| Reverse | A trunk is selected started with the last trunk in the group in descending order. |
| UCD | Uniform Call Distribution. The start hunt member is randomly selected, the hunting following Forward Circular Sequential hunting. |
| DMS-100 Switch Type | Description |
| ASEQ | Hunt members are assigned a selection sequence of Ascending. ASEQ select the first available trunk in the selection sequence (ascending or descending). |
| CWCTH | Hunt members are assigned a selection sequence of Clock-wise circular. Clock-wise circular will select the first trunk available after the one most recently released. |
| CCWCTH | Hunt members are assigned a selection sequence of Counter Clock-wise circular. Counter-clock-wise circular will select the first trunk available after the one most recently released. |
| DSEQ | Hunt members are assigned a selection sequence of Descending. DSEQ select the first available trunk in the selection sequence (ascending or descending). |
| LIDL | Hunt members are assigned a selection sequence of Least Idle. Least Idle re-selects the last trunk used. |
| MIDL | Hunt members are assigned a selection sequence of Most Idle. Most Idle distributes calls uniformly to all trunks in the group |
You must indicate on the RS form which T1 and channel that will be used for each trunk. Qwest will always assign a D channel or back-up D channel to channel 24 of the T-1, however, you must indicate the channel assignment for both B and D channels on existing service.
For existing service, use the FEATURE DETAIL field on the RS form for each trunk. In the FEATURE DETAIL field populate the CFA FID, followed by the T1 and channel designation, e.g., CFA 101 T1 23 CLLI CLLI.
For a new installation (ACT N), enter trunk information in REMARKS field of the RS form, e.g., 5 call-by-call 2-way trunk channels 1-5, 5 dedicated DID trunk channels 15-20, D channel - channel 24. If a request for a new installation is received without this information, Qwest will put the D channel in channel 24 and use the other channels in order from 1-23, assigning members of a trunk group to contiguous channels.
In addition to the fatal IMA reject errors, Qwest will error or reject your request if the information provided for ISDN PRI is contradictory or insufficient to provision the service. In most instances, you will receive a telephone call asking for a Supplement (SUP) to your request, followed by an error message in IMA. If the information needed is not provided within four hours of the telephone call, your request will be rejected. Following are some examples of requests that may error or reject:
Additional rejection errors can be found in the Ordering Overview.
Use of Universal Service Order Codes (USOCs) and Field IDentifiers (FIDs) are described in the USOCs and FIDs Overview. Use of the USOC/FID Finder will assist you in identifying USOC and FID requirements.
