Network Element Notching Instructions CURRENT Group, LLC Network Element Notching Instructions February 29, 2008 2 1. Notching Overview In order to comply with FCC requirements on mitigation and avoidance measures it is necessary for the administrator to be able to track the notching on any CURRENT Group unit. Depending on the results, the administrator may need to modify the notching settings. Notching scripts reside on the NEC server in the CURRENT Group BPL system. The administrator is able to access and run these scripts by logging in to the NEC server. The administrator then enters the appropriate command to run the pertinent script. The scripts are described in further detail below. 1.1 Get Notching Settings The administrator logs into the NEC server and follows the steps listed below to obtain the notch settings for a particular CURRENT Group unit. The administrator will need the following parameters in order to run the script: -s <sn> = serial number of the unit. This is used to calculate the SNMP pass phrase. -i <ip> = IP address of the unit from which you want the current settings. 1. At the Unix command line enter: get_notching –s <sn> -I <ip> The executed script will return the notching values currently set on the selected unit. The output is displayed as a list of 84 characters, and whether or not the carrier is currently enabled, where 1 = enabled, and 0 = disabled. 1.2 Set Notching Settings The administrator logs into the NEC server and follows the steps listed below to set the notching settings for a particular CURRENT Group unit. The administrator will need the following parameters in order to run the script: -s <sn> = serial number of the unit. This is used to calculate the SNMP pass phrase. -i <ip> = IP address of the unit to be modified. -C <notchedcarriers> = comma separated list of carriers. Carriers are listed as 1 through 84. 1. At the Unix command line enter: set_notching –s <sn> -i <ip> -C <comma separated list of carriers to disable> The executed script will set all carriers to be enabled except for the HAM band and any other carriers specified. If this script is run without specifying any carriers, then the notching is set to the default setting with only the HAM band set to be disabled. CURRENT Group, LLC Network Element Notching Instructions February 29, 2008 3 1.3 Calculating The Carrier to Notch The correspondence between carrier number and carrier frequency is shown for the low voltage domain in the table below.

To create a notch >10 dB deep, only a single carrier need be notched. To create a notch >20 dB deep, it is necessary to notch 6 additional carrier on either side of the center frequency of interest. Example: In order to create a notch of >20 dB at a frequency of 5.86 MHz, it is necessary to notch carriers 2-7 and 9-14 in addition to carrier 8. To achieve this, the following command would be entered at the NEC command line interface: set_notching –s <sn> -i <ip> -C 2,3,4,5,6,7,8,9,10,11,12,13,14

General Information Applicant: CURRENT Group, LLC Applicant Address: 20420 Century Boulevard Germantown, MD 20874 301-944-2700 Equipment: CURRENT Bridge URD 6111 Equipment Description: The CURRENT Bridge URD 6111 is part of an Access BPL system. It operates on underground public utility power lines over low-voltage and medium- voltage wires. The CURRENT Bridge URD 6111 is the device that routes and controls data traffic between the low- and medium-voltage lines. The CURRENT 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 CURRENT Coupler Assembly URD 6300 and over the low-voltage system by a standard 240V two-wire connection.
