Some Qwest products generate usage records or call detail that is recorded at a Qwest Central Office Switch. This recorded usage is subsequently processed within the Customer Records and Information System (CRIS) billing system and, if identified as belonging to you, is packaged into a file, the Daily Usage File (DUF). The DUF is transmitted to you on a daily, weekly or monthly basis depending on what you requested in the New Customer Questionnaire. ) Qwest bills usage records based on applicable tariff, Interconnection Agreement, and/or Commercial Agreements applying the rated usage to your bill. Products that generate recorded usage records can include, but are not limited to the following:

The DUF is available upon request in the Qwest 14-state local service territory.
To receive a DUF, Qwest must be the underlying network provider for local service.
DUF records can be for toll, access and local usage. These charges apply only to the wholesale channel, which are designated as RSID/ZCID accounts.
The rate to be charged per record will differ by state. Please refer to your Interconnection Agreement for specific rates.
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 as a Reseller. 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.
The DUF can be transmitted in three different media types to you. You will choose the method of transmission when completing the New Customer Questionnaire. Once the questionnaire is completed and submitted, a technical review of the questionnaire will be done by a representative from the Qwest Information Technology (IT) Wholesale Systems Implementation and Deployment Team. This representative will schedule a meeting with you to assist with any technical questions regarding the DUF.
The media types are:
The New Customer Questionnaire requires you to provide the following information concerning the Daily Usage Output:
NOTE: If you wish to change your DUF media type after you are established, it will be necessary for you to resubmit a New Customer Questionnaire advising of the requested media change. The questionnaire is submitted per the procedures outlined on the questionnaire.

DUF Record Format
The DUF is sent to you in Ordering and Billing Forum (OBF) Exchange Message Interface (EMI) format. Recorded call information, will conform to EMI guidelines for each applicable recorded usage record and record type. Applicable usage records are dependent on the Class of Service for each account. For example, a Measured Class of Service includes all local usage records, but a Flat Class of Service does not include local usage. In order for you to be able to read and understand the record layout, you must order the EMI Documentation (SR 320) prepared by OBF.
Types of Records in DUF
Once you become the provider of record on a line, Qwest will report to you, as appropriate and applicable, all usage associated with that line, including local, intraLATA (Local Access and Transport Area) and switched access. Examples of some recorded usage records you will receive on the DUF are Directory Assistance (DA), Local Measured Service (LMS), usage sensitive CLASSTM features Qwest provided intraLATA toll and, if applicable, originating and terminating switched access records.
DUF Processing
Recorded usage records are processed daily and posted to internal toll guides generated by service order activity within Qwest’s billing systems. Toll guides are also used to identify the Competitive Local Exchange Carrier (CLEC) who is to receive the recorded usage sent on the DUF. Additionally, recent service order activity is checked prior to sending records to the DUF to ensure usage is processed correctly.
Reseller DUF
If you establish as a Reseller you will only receive recorded usage (non access) records on your DUF. The DUF file itself will be generated and delivered in the format requested by you in the New Customer Questionnaire. A single DUF file will be created per CRIS region; Central, Eastern or Western. The recorded usage records within each DUF file are sorted internally by the originating numbers Regional Account Office (RAO), creating multiple "packs" of recorded usage records in each DUF. For example, all recorded usage records in RAO 153 are packed together with a header/trailer while all recorded usage records in RAO 062 are packed together with a different header/trailer, but both of these "packs" appear in the single DUF file.
UNE DUF
If you are established as a UNE provider, you will receive not only recorded usage records but also originating and terminating switched access records on your DUF. All switched access records are "packed" into a single file per CRIS region with only one header/trailer. Unless otherwise specified, you will receive both recorded usage records and switched access records on the same DUF file (parsed internally by specific EMI header/trailer records). As a UNE provider you also have the option of splitting your DUF file by separating the recorded usage records into one file (commonly referred to as the ODUF) and the switched access records into another file (commonly referred to as the ADUF). Information supplied by you on the New Customer Questionnaire identifies which method is selected to receive your DUF file(s).
DUF Transmission Days
Normally, you will receive the DUF daily (Monday through Friday, excluding Qwest holidays). If there is no usage recorded on a particular day, you will not receive a file or any notice from Qwest that usage was not recorded, and a file will not be sent.

Depending upon the type of call made, the DUF can include, but is not limited to, the following types of rated or unrated usage records and/or access records:
The following is a list of common EMI record types generated by Qwest:
(Note: Any valid local or toll EMI record type originating from other CLECs or Independent Local Exchange Carriers (ILEC) can be passed on the DUF):
Rated Usage
Rated Usage records are usage records that Qwest receives from other CLECs and ILECs.
Unrated Usage
Qwest usage recorded at a Qwest Central Office (CO) switch comprises a majority of the usage appearing on the DUF. This recorded usage is subsequently processed within the CRIS billing system and once identified as belonging to a CLEC, is packaged into the DUF. Some examples of unrated usage are:
NOTE: The DUF will not contain usage records coming from an Interexchange Carrier (IXC) for your end-user billing. Any usage records Qwest receives from an IXC that involve a CLECs end-user will be returned to the IXC per industry guidelines.
Any usage questions should be referred to you Qwest Billing Service Delivery Coordinator (SDC).
Returns
If you need to return DUF records to Qwest, you may do so for any number of reasons, among which are:
Records are sent to you in packs that are groups of messages with a header and trailer. If the pack errors, the return of the pack is handled over the same circuit that was used to transmit the DUF to you.
You can also return to Qwest record level errors, which are individual records within a pack. In order for you to return these record level errors mechanically, you must subscribe to the Co-Carrier Usage Return (CCUR) system.
To subscribe to CCUR, complete the section of the New Customer Questionnaire regarding CLEC Usage Return. The information included in this section is:
When records are returned, you must also provide return reason or error codes that explain why the records are being returned. You must return any usage errors within 90 days. Return reasons and/or error codes can be found in the EMI documentation produced by OBF.
Complete requirements and other required information will be provided to the CLEC at the time they subscribe to CCUR.
When usage is returned to Qwest, the CCUR system will attempt to re-guide (re-direct) the records for up to three business days. During that time, various results are possible including the following:
Usage record found to be correct
CCUR rejects the record
CCUR re-guides the record
CCUR is unable to correct the record(s)
If you need a retransmission of the DUF, you should contact the Wholesale Systems Help Desk and be prepared to give the following information:
Usage Data is stored for 180 days at Qwest. After that time, retransmission is not possible and a request for retransmission will be denied.
