  • To provide CLEC customers:

    • an understanding of Daily Usage Files (DUF)

    • the features and benefits of each file type

    • the data transmission delivery methods available

    • additional website references


• This package is designed for CLEC’s that offer Resale Services, Unbundled Network Element Platform (UNE-P) Services, and/or Wholesale Local Platform Services to the end user customer market place.

Understanding the Daily Usage Files (DUF)

Three Types of Daily Usage Files (DUF)

  • Access Daily Usage Files (ADUF) contains originating and terminating access carrier messages (including ICO, Wireless, Facility Based and IXC messages) associated with Unbundled Network Elements (UNE) switch ports

  • Optional Daily Usage Files (ODUF) contains end user billing records which can be used by the CLEC to bill its end users for directory assistance charges, vertical features (such as *69) and local usage for usage sensitive calling plans. NOTE: For Resale customer’s, flat rate local calls are omitted from this file.

  • Enhanced Optional Daily Usage Files (EODUF) provides the flat rated local calls originating from resold Flat Rate Business and Residential lines. NOTE: EODUF is only available for those CLECs who purchase ODUF.

Features and Benefits of ADUF

ADUF provides the CLEC call detail on:

  • their end user’s originating and terminating calls carried by an Interexchange Carrier (IXC)

  • calls to their end users from other service providers such as: ICO, wireless and facility-based end users.

    This information will enable the CLEC to charge other providers (i.e., IXCs, Wireless providers, and facility-based CLECs) for messages carried on their network for their end user customer. NOTE: This holds true if an interconnection agreement exists between the CLEC and the other providers.

Features and Benefits of ODUF

ODUF provides the CLEC with:

  • Daily access to end user’s local billing data

  • Call data that the CLEC may use for marketing analysis

  • Call data to assist with fraud prevention. Daily access to end user’s data gives the CLEC the opportunity to review large volumes of usage data associated with a particular end user. It also provides an opportunity to establish specific end user limits on toll charges.

Features and Benefits of EODUF Files

EODUF provides the Resale CLEC with:

Usage based products and helps the CLEC distinguish between the prepaid market and the flat rate market.
