                              NOTICE OF VIOLATION

   Released: October 24, 2012

   By the District Director, Denver Office, Western Region, Enforcement
   Bureau:

    1. This is a Notice of Violation (Notice) issued pursuant to Section 1.89
       of the Commission's rules (Rules), to Comcast of Colorado IX, LLC
       (Comcast), operator of a cable system  in Aurora, Colorado.  Pursuant
       to Section 1.89(a) of the Rules, issuance of this Notice does not
       preclude the Enforcement Bureau from further action if warranted,
       including issuing a Notice of Apparent Liability for Forfeiture for
       the violations noted herein.

    2. On October 16, 2012,  in response to a complaint of interference,
       agents of the Enforcement Bureau's Denver District Office inspected 
       Comcast's cable system  located near  2033 S. Pagosa Street, in
       Aurora, Colorado, and observed the following violations:

     a. 47 C.F.R. S: 76.605(a)(12): "As an exception to the general provision
        requiring measurements to be made at subscriber terminals, and
        without regard to the type of signals carried by the cable television
        system, signal leakage from a cable television system shall be
        measured in accordance with the procedures outlined in 76.609(h) and
        shall be limited as follows: Less than and including 54 MHz, and over
        216 MHz - 15 micro-volts per meter measured at 30 meters." At the
        time of the investigation, the agents measured signal leakage in
        excess of 15 mV/m on the frequency of 781.25 MHz. The actual field
        strength measurement was calculated as 43 mV/m at 30 meters.

     b. 47 C.F.R. S: 76.613: "(a) Harmful interference is any emission,
        radiation or induction which ... seriously degrades, obstructs or
        repeatedly interrupts a radiocommunication service operating in
        accordance with this chapter. (b) [A multi-channel video programming
        distributor] that causes harmful interference shall promptly take
        appropriate measures to eliminate the harmful interference." At the
        time of the investigation, the agents observed signal leakage in the
        700 MHz band. The signal was characterized as a continuous,
        un-modulated carrier operating at 781.25 MHz that was causing harmful
        interference to Verizon's 700 MHz LTE (4G) operations.

    3. Pursuant to Section  403 of the Communications Act of 1934, as
       amended, and Section 1.89 of the Commission's Rules, we seek
       additional information concerning the violations and any remedial
       actions taken.  Therefore, Comcast must submit a written statement
       concerning this matter within twenty (20) days of release of this
       Notice. The response (i) must fully explain each violation, including
       all relevant surrounding facts and circumstances, (ii) must contain a
       statement of the specific action(s) taken to correct each violation
       and preclude recurrence, and (iii) must include a time line for
       completion of any pending corrective action(s). The response must be
       complete in itself and must not be abbreviated by reference to other
       communications or answers to other notices.

    4. In accordance with Section 1.16 of the Commission's Rules, we direct
       Comcast to support its response to this Notice with an affidavit or
       declaration under penalty of perjury, signed and dated by an
       authorized officer of Comcast with personal knowledge of the
       representations provided in Comcast's response, verifying the truth
       and accuracy of the information therein, and confirming that all of
       the information requested by this Notice which is in the regulatee's
       possession, custody, control, or knowledge has been produced. To
       knowingly and willfully make any false statement or conceal any
       material fact in reply to this Notice is punishable by fine or
       imprisonment under Title 18 of the U.S. Code.

    5. All replies and documentation sent in response to this Notice should
