DSU II Telephone Attendant Manual

    We hope you find the information in the User's or Reference Guides helpful and useful in
    the operation of your telephone system.  To the best of our ability, the information is
    accurate and is the latest the manufacturer has to offer.  However, at times guides like
    those listed above are helpful but not nearly enough.  We look forward to the opportunity
    to assist you in making changes and programming the system to function to your
    specifications.  Please contact us to request a service call.
