TY7210-0115Overhead Backhaul-Point and Bridge

20420 Century Boulevard Germantown, MD 20874 (301) 944-2700 (phone) (301) 944-2701 (fax) Test Report Attestation According to testing performed by CUURENT Technologies, LLC, the CT Backhaul-Point ® OH 5000g and the CT Bridge ® OH 5000ml are in compliance with the electromagnetic compatibility requirements defined in FCC Rules, Part 15, Subpart G. Details are shown in the accompanying test report. Date: June 12, 2006

To: FCC OET Laboratory, ATTN Steve Martin From: CURRENT Technologies Regarding: Correspondence 31194, FCC ID TY7210-0115, EA749943 The correspondence noted above raised a number of questions. These questions are listed in boldface below, with the answer directly below the questions: Q: The two devices described in this application are not electrically identical and, therefore, require separate applications and FCC ID numbers. Since the test report covers complete testing on only the CT Bridge, it is recommended that the current application be changed to apply only to the CT Bridge and that a second application be submitted for the CT Backhaul Point. Please advise. A: This question will be answered in a later submission. Q: Submitted installation manual does not include any operator instructions related to complying with FCC interference mitigation and avoidance requirements. Please provide sections of operator instruction manual for this EUT or for the system controller relevant to compliance with these requirements. (E.g., achieving the notch depth requirements in 15.611(c) may require masking out several carriers beyond the edge of the band to be protected. How is this information conveyed to the operator?) A: An operator document describing the notch conditions is attached to this correspondence reply. Q: What was the burst rate of BPL signal injection onto the power lines during testing for each band of operation? Q: Please specify the maximum RF injection duty factor achievable by the device and identify the duty factor of signal injection during testing for both bands of operation. A: (To both questions above) To generate test traffic on both medium voltage and low voltage, a special mode in the device was used that forces the BPL modem to continuously generate transmission on the line. This works by forcing the modem under test to repeatedly and continuously transmit system overhead messages. The ‘mfgviperon’ command transmits these in a manner that exceeds the normal ability of the modem to generate traffic in actual use, by repeatedly sending these overhead messages to a remote station on the powerline. These messages generate 200 OFDM symbols over 40 times per second, ensuring that the 20 pulse per second minimum is exceeded, and that the transmit rate approaches the maximum achievable with these signals in actual operation. As the maximum duty cycle in a CSMA network such as this is indeterminate; this technique ensures that a repeatable measurement can be conducted while ensuring that the quasi-peak detection filter is not allowed to decay, and reduce the measured level in a manner not indicative of its maximum transmission.

See 47 C.F.R. § 0.457(d)(2). Disclosure or publication of any portion of this confidential material to other parties could cause substantial competitive harm and provide unjustified benefits for competitors. The information in these exhibits is not available to the general public. This information, including that in the internal photos, is not disclosed to third parties except under protection of a confidentiality agreement that prohibits further disclosure. Therefore recipients of this information are constrained by contract from showing the equipment or discussing its operation to anyone not approved by CURRENT. Although the underlying equipment is installed outdoors, all installations (as well as equipment removal and in-situ maintenance) are performed only by certified utility company linemen or contractors, and once installed the equipment resides in the “power space” of utility poles where electric distribution lines are hung. Access to this space is very dangerous and under the National Electric Safety Code is strictly limited to qualified utility workers certified to work within such “power space.” Finally, the underlying equipment is serviceable only by CURRENT or a CURRENT- authorized third party. As a result, the design details of the equipment, including internal photos, are hidden from competitors and protected against public disclosure. The equipment design, as shown in the internal photos, was developed by CURRENT at great expense. Disclosure of this information via the FCC website would convey an unfair and unearned competitive advantage to other companies in this market. CURRENT is entitled to have the information protected pursuant to Worthington Compressors v. Costle, 662 F.2d 45, 51 (D.C.

To: FCC OET Laboratory, ATTN Steve Martin From: CURRENT Technologies Regarding: Correspondence 31239, FCC ID TY7210-0115, EA749943 NOTE: This reply to correspondence modifies the operational description and is included in the Request for Confidentiality filed with the original application. The correspondence noted above raised two questions. These questions are listed in boldface below, with the answer directly below the questions: Q: We await a new version of the ‘Notching Instructions” document correcting the number of carriers that must be masked. A: A Revised Notching Instructions is attached to this correspondence. Q: Please provide quantitative measurement of RF injection duty factor achieved during testing. A: As noted in the reply to correspondence 31194, the ‘mfgviperon’ command is designed to create repeated system overhead messages that fully exercise the quasi-peak detector and can be duplicated in both the field and lab environment. The command creates a burst of 200 OFDM symbols that get repeated at least 40 times per second, easily exceeding the 20 pps requirement. To illustrate this point, the signal was generated in a laboratory and its time domain waveform captured. This data is shown below. The figure below shows a plot of the 200 OFDM symbol burst. Test Waveform - Zoom on Test Pulse -60 -50 -40 -30 -20 -10 0 -0.00020 0.00000 0.00020 0.00040 0.00060 0.00080 0.00100 0.00120 0.00140 0.00160 Time (seconds) Relative Amplitude of Signal (dB) Note that the burst is longer than 1 ms, ensuring that the signal remains continuously on during the rise time of quasi-peak detection filter. A plot of the bursts over a full second is shown below, in a plot of a full second of the waveform. Test Waveform over 1 second period -70 -60 -50 -40 -30 -20 -10 0 0.0000.1000.2000.3000.4000.5000.6000.7000.8000.9001.000 Time (seconds) Relative Amplitude of Signal (dB) The repeated bursts ensure that the quasi-peak filter decay constant is not allowed to fully discharge, thereby ensuring that the measurement will register the maximum possible emissions as called out in Appendix C.

To: FCC OET Laboratory, ATTN Steve Martin From: CURRENT Technologies Regarding: Correspondence regarding test signal duty cycle In addition to the reply data previously submitted on 25 July 2006, we offer the following data on the specific test signals used and the impact on emissions measurements. As previously submitted, the ‘mfgviperon’ command used for testing is designed to create repeated system overhead messages that fully exercise the quasi-peak detector and can be duplicated in both the field and lab environment. The command creates a burst of 200 OFDM symbols that get repeated at least 40 times per second, easily exceeding the 20 pps requirement. To illustrate this point, the signal was generated in a laboratory and its time domain waveform captured. This data is shown below. Figure 1 shows a plot of the 200 symbol OFDM burst. Test Waveform - Zoom on Test Pulse -60 -50 -40 -30 -20 -10 0 -0.00020 0.00000 0.00020 0.00040 0.00060 0.00080 0.00100 0.00120 0.00140 0.00160 Time (seconds) Relative Amplitude of Signal (dB) Figure 1: Test Waveform - Zoom on Test Pulse Note that the burst is longer than 1 ms, ensuring that the signal remains continuously on during the rise time of quasi-peak detection filter. A plot of the bursts over a full second is shown in Figure 2, in a plot of a full second of the waveform. Test Waveform over 1 second period -70 -60 -50 -40 -30 -20 -10 0 0.0000.1000.2000.3000.4000.5000.6000.7000.8000.9001.000 Time (seconds) Relative Amplitude of Signal (dB) Figure 2: Test Waveform over 1 Second Period The repeated bursts ensure that the quasi-peak filter decay constant is not allowed to fully discharge, thereby ensuring that the measurement will register the maximum possible emissions as called out in Appendix C. It can be properly noted that the overall duty cycle of this transmission is relatively low, although the burst rate is fairly high. Laboratory testing of the signal shown in Figure 2 registered a quasi-peak level of 71.9 dBμV. To compare this against a signal with a very high duty cycle, the same unit used for the tests in Figures 1 and 2 was used to generate a high rate of throughput so that the duty cycle approached 100%. The resulting waveform is shown in Figure 3. Test Waveform with High Duty Cycle -50 -45 -40 -35 -30 -25 -20 -15 -10 -5 0 00.10.20.30.40.50.60.70.80.91 Time (seconds) Relative Amplitude (dB) Figure 3: Test Waveform with High Duty Cycle A quasi-peak level of this waveform provided a level of 71.3 dB, or 0.6 dB less than the test signal used in all field testing. The test signal provides a full exercise of the quasi- peak detector in a repeatable manner that can be readily achieved in the field. This ensures that field testing registers the maximum emissions and can be done in a repeatable manner.

General Information Applicant: CURRENT Technologies, LLC Applicant Address: 20420 Century Boulevard Germantown, MD 20874 301-944-2700 Equipment: CT Bridge OH 5000ml CT Backhaul-Point OH 5000g Equipment Description: The CT Bridge OH 5000ml and CT Backhaul-Point OH 5000g are parts of an Access BPL system. They operate on overhead public utility power lines over low-voltage and medium-voltage wires. The CT Backhaul-Point OH 5000g is the primary data router that connects the BPL system to the local point of presence; aggregating and managing the data traffic from its downstream CT Bridges. Each CT Backhaul-Point has two interfaces: a backhaul Ethernet interface to a fiber-optic or wireless connection; and a medium voltage interface through the CT Coupler ® to the MV primary cable. The CT Bridge OH 5000ml is the device that routes and controls data traffic between the low- and medium-voltage lines. The CT Bridge serves as a gateway to all customers powered from the same distribution transformer as itself. It communicates over the medium-voltage lines via the CT Coupler and over the low-voltage system by a standard 240V two-wire connection.
