NCREN QUALITY ASSURANCE DOCUMENT CHAPTER: Network Control STATUS: Approved TITLE: System Start-up PAGE: 1 of 1 SPEC#: CTL.VST.001 AUTHOR: Jeff Stanfield DATE: Approved November 1997; Revised format and minor content changes July 2001. I. Purpose All sites’ capabilities and services vary, thus, individual start-up procedures will vary across institutions. This document details the basic sequential steps of the daily start-up routine performed by the site representative to ensure all NCREN systems and equipment are operating normally. II. Steps A. Arrive at least 30 minutes prior to the first session of the day. B. “Power On” equipment in all areas including, but not limited to: control room, classroom, conference room, and student seating. All equipment should be powered regardless of specific requirements for that session. The reason for complete power usage is to verify equipment performance and to determine if repair is needed. C. Inspect video source and destination equipment and signal quality. For additional instructions, read CTL.VST.002. D. Inspect audio source and destination equipment and signal quality. For additional instructions, read CTL.AUD.001. E. Verify routing of audio and video sources and destinations to ensure proper pathways. F. If your site uses a CAMVision-2 codec, verify that the PC is powered and that the software is the only application running while the session is connected. G. Run an audio train. For detailed instructions, read CTL.AUD.002. H. Go on-line with NCREN. Begin audio and video checks with Network Control and distance sites to verify sound and video quality. For additional instructions regarding microphone checks, read CTL.AUD.003. I. Greet participants and provide an orientation if necessary. For additional instructions, read CTL.AUD.006. III.

I. Purpose This document directs the site operator on the local video setup procedures required prior to connection to NCREN. II. Steps A. Arrive at least 30 minutes prior to the session start time. B. Power on cameras. Allow at least a 15-minute warm-up on tube cameras for maximum video quality. CCD cameras do not required a warm-up period. Check phasing and timing. C. Verify white/black balance and registration of cameras. D. Inspect video source and destination equipment, including but not limited to: verification of video levels (100 IRE), ID generator, etc. E. Set the video router to its proper inputs and outputs for normal operation. F. Verify camera shot selections (wide, graphic, individual). G. Verify lighting to eliminate shadows. H. If your site uses a CAMVision-2 codec, verify that the PC is powered. I. Inform Network Control of any circumstances that might interrupt a session (i.e. nearby construction or maintenance work) so that all participating sites can be notified. III. Related Documents A.

Heath DATE: Reviewed October 1997; Revised format and minor content changes July 2001. I. Purpose This document outlines the procedure for providing services and maintaining session continuity in the event of a network outage. II. Steps In the event of a network outage (loss of one or more video or audio signals), Network Control will strive to maintain session continuity by using alternate paths. If continuity cannot be accomplished, Network Control will take the following steps: A. On-air sessions will receive first priority. Network Control will utilize alternate paths, including codec channels, facilities, equipment, and phone line interfaces to provide video and audio continuity for the on-air session. B. While troubleshooting, Network Control occasionally uses program audio to inform sites and participants of the nature of a problem. C. If the technical difficulty does not impact all sites participating or scheduled to participate in a session, the originating site determines whether to continue, start, or cancel the session with the limited sites and resources as conveyed by Network Control. D. If Network Control is aware of a problem that will prevent an upcoming session from being transmitted, the following progression of notifications will occur: 1. Network Control notifies the video manager or site operator at the originating site. Managers and operators at the affected sites will be notified subsequently, or simultaneously, if the orderwire is used and available at the given site. 2. Video Services and Coordination is notified immediately. They inform the program coordinators. 3. Program coordinators will attempt to notify the session participants of a session or local site cancellation and, if known, alternative plans (e.g. late start, optional sites) for the session. 4. A combination of methods may be used to ensure widespread notification of technical difficulties, including orderwire, telephone, video slates, and electronic mail. E. A videotape may be made available if a session cannot be transmitted. 1. The originating site may provide a videotape of the session, if permissible by the site’s local recording practices. 2. When the originating site is unable to record the session, Network Control will facilitate a recording if permission is granted from the originating site. Either a site participating in the session or Network Control may provide the actual recording. 3. Delivery or re-transmittal of the videotape will be accomplished in the most expeditious, practical, and cost-effective manner. F. Network Control will provide updates, as they become available, to sites and Video Services and Coordination (when necessary for upcoming sessions and scheduling options) regarding the status of the technical difficulties and expected time of resolution.

Purpose Provides instructions for connecting the CAMVision-2 MPEG2 unit in a point-to-point session. II. Steps A. Locate the CAMVision-2 Model 7615. B. Turn the power on, indicated by a solid green light above the light bulb icon. C. When powering up, allow the codec to bring itself up to the Controller window. 1. Once the codec boots up, the CAMVision-2 Session Controller should open automatically. 2. If it does not, open the Controller from the Start Menu. 3. Next, open the CAMVision-2 Dialer from the Start Menu. Note: Using the Dialer is the easiest way to establish connections. D. The CAMVision-2 codecs at both sites should be powered up, with the Controller and Dialer open on both codecs. Both Dialers should say “Ready to dial.” The Auto Answer button should be depressed, which will register as a light blue color. E. The originating site should locate the receive site on the appropriate Speed Dial page, and click on the “@” symbol to speed dial the desired site. When the connection is established, “Ready to dial,” will change to “Connected to (site name)-mp#. F. The IP address of the receive site can be keyed in using the number keys on the Dialer if the site is not loaded into Speed Dial. After entering the IP address, hit the orange Speakerphone button to complete the connection. G. After the conference is complete, remember to hang up using the Speakerphone button and watch the display return to “Ready to dial.” H. When powering down the CAMVision-2, remember to close the Dialer and the Controller before shutting down under the Start Menu. 1. Close the Dialer by selecting “Exit” under “File.” 2. Select the “X” button to close the Controller. 3. Wait for the window stating, “It is now safe to turn off your computer,” before powering down. Both the red and the green lights on the front of the codec will go dark. I. Power to the CAMVision-2 codec should never be turned off without first disconnecting from an existing session, closing the dialer, closing the controller, and shutting down the computer. J. Problems will occur connecting in later sessions if this procedure is not followed because the far end CAMVision-2 codec will not recognize that it is no longer in a session K. “Line is busy” on the display usually means that the far end CAMVision-2 is in use. This message can also appear if the CAMVision-2 lost power while connected in a session. If the destination codec is not really in a session, basic troubleshooting should clear the problem. NCREN Controlled Document NCREN QUALITY ASSURANCE DOCUMENT CHAPTER: Network Control STATUS: Approved TITLE: Connecting the CAMVision-2 PAGE: 2 of 2 SPEC#: CTL.VST.004 AUTHOR: Brian Gourley, Donna Harrison, Peter Valentine DATE: July 2001 L. The most common window to indicate a problem in connection states “No response from destination CAMVision-2.” This may simply indicate the far end codec is not on or that the proper application (Controller or Dialer Application) is not open. If the codec is powered up, go through the basic troubleshooting tips. See document CTL.VST.005. III. Related Documents A.

Purpose This document provides basic troubleshooting procedures when a connection cannot be established, or when an established connection becomes unusable. II. Steps If the connection is not established, try the following steps. Executing them simultaneously at both sites will save time and will not harm the MPEG2s. If at any time an “Application Error” (Dr. Watson) appears, contact Network Control for further assistance. A. Close the Dialer and the Controller. B. Re-open the Controller and the Dialer. 1. The originating site should attempt to reestablish the connection through the Dialer. 2. If a connection still cannot be established or the Dialer indicates “Line is Busy,” proceed to step E. (The Session Controller may be hung and erroneously think that it is in a session.) C. Select the Controller window as active. D. Select the Start button (the top one with the green arrow). E. Observe “Session in Progress” beside “System” for approximately 10 seconds. F. Select the Stop button (the bottom one with the red rectangle). G. Observe “Ready” beside “System”. H. The originating site should then attempt to reestablish the connection through the Dialer. If a connection still cannot be established, proceed to step K. I. Both originating and receive sites can start their own codecs from the Controller to establish the connections. Remember that both sites must break their own connections at the conclusion of the session. 1. Close the Dialer Application. 2. Select “Session Configuration” on the Session Controller. The Session Configuration will open with the Encoding page. 3. Under the General encoding settings the Encoder Enable box should have a check mark and the Encoding Rate should be set at 5.4 Mb/s. a) Set the Host ID/Address for the IP address of the far end CAMVision-2. b) Set the Port/VCI to 13000. 4. Go to the Video tab on the Encoding page and set PTS Enable (A check mark should appear in the “PTS Enable” box). 5. Go to the Decoding tab on the Session Configuration page. a) The Decoder Enable box should have a check mark.

J. b) Set the Port/VCI to 13000. Go to the Network tab on the Session Configuration page. a) The Mode should be set to Network and the Method should be set to Unicast. Click “OK” on the Session Configuration page (if “Cancel” is selected no configuration changes will not be saved). Once the Session Configuration is set on both the originating and receive sites, the session can be started by selecting the Start (green arrow) button on the Session Controller. To end the session, both sites must select the Stop (red rectangle) button. If a connection still cannot be established, close the Dialer, close the Controller, and shut down the computer. 1. If time is not a factor, try restarting the computer when the message appears, “It is now safe to turn off your computer.” 2. If time is a factor, go ahead and turn off the power when the message appears. Leave the codec off for at least 30 seconds before powering it back up. K. Contact Network Control at 919-248-1410 for additional assistance. III. Related Documents A. CTL.VST.004 NCREN Controlled Document Connecting the CAMVision-2 NCREN QUALITY ASSURANCE DOCUMENT CHAPTER: Network Control STATUS: Approved TITLE: Session Overages PAGE: 1 of 1 SPEC#: CTL.VST.006 AUTHOR: Darleene M. Heath DATE: July 2001 I. Purpose This document discusses same day and in progress sessions that need to extend beyond the time scheduled on the NCREN logs. II. Steps A. All program coordinators to should review their sessions weekly (and daily if necessary) to ensure that all resources, including the start and end time, are scheduled appropriately. B. If a site representative realizes prior, to the start of a session, that the time needs to be modified, the representative should contact videoreq to determine what modifications can be made. C. If a site representative realizes while the session is in progress that more time is required, then the site should immediately contact Network Control to determine the feasibility. D. Generally, Network Control will allow a 3-minute overage when an upcoming session is scheduled in the same control room. Additional time can be allowed if all required resources are available. Network Control will inform the requesting site representative of the amount of additional time that can be allowed. E. Note that even if central resources are available and the extension poses no problem for Network Control, individual sites may have their facilities reserved for other activities. The originating site representative should confirm availability with all institutions and Network Control. F. Once confirming availabilities with Network Control and all participating sites, the originating site representative should inform the session host who should make an announcement over the air. G. Network Control will inform the rep of how many additional minutes are available. H. Network Control will not jeopardize the setup and testing of an upcoming session to allow an inprogress session to extend beyond the scheduled time. I. Billable sessions (i.e. dialup, overtime) will incur increased charges if they extend beyond the scheduled time. III. Related Documents A. ADM.GRP.002 B. ADM.GRP.005 C.
