  • Page 4: About This Manual

    ABOUT THIS MANUAL This manual describes the ADC PWR-AVIS system. The manual provides a product description, installation instructions and operational information. ADMONISHMENTS Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided.

    PWR-AVIS USER MANUAL 1 GENERAL This manual describes the features, functions, and installation of the ADC Power Analog Video Interface System (PWR-AVIS) which is available with single or dual (redundant) power supplies. PWR-AVIS provides centralized access for testing, monitoring, patching, or amplification of digital, analog video, or baseband signals.
  • Page 6 ADCP-61-814 Issue 1 April 1999 PWR-AVIS is typically used in headend or distribution offices to provide access to individual 4.5 MHz (NTSC or PAL) baseband video channels, data, intermediate frequencies or other headend signals from the video backbone network. A typical network employing PWR-AVIS...
  • Page 7: Description

    2.1.1 Chassis The PWR-AVIS chassis are 3.5 inches (8.9 cm) high and mount in either 19- or 23-inch (48.3 or 58.4 cm) equipment racks. Reversible mounting brackets are provided for accommodating either rack type. The protective front cover slides into the chassis when circuit access is required.
  • Page 8: Functional Description

    PWR 1 slot. 2.2 Functional Description PWR-AVIS provides a central jack access point between network elements (NE). See on the next page. The jack access cards provide access to circuits for monitoring and maintenance functions. (The jack circuitry automatically provides 75-ohm termination.) The jacks also provide patching functions to bypass defective equipment and/or isolate problems in circuit links.

  • Page 10 The dual or redundant powering option provides two power supply modules for powering the RIUs. Figure 7 shows an example of this configuration. Figure 7.

  • Page 11 2.2.3 Single/Dual Powering and Alarms When PWR-AVIS is configured with a single power supply, only the PS1 alarms should be used. If the power supply fails in this configuration continuity will occur between the PS1 alarm terminals and all RIUs will lose power.
  • Page 12 • Active (0, +10 and +20 dB gain amplifier) cards without access jacks. PWR-AVIS Cards, except for the 0,10 and 20 dB active (amplifier) cards, provide the means to access circuits for monitoring and maintenance functions or to amplify an incoming signal. See Figure 10.
  • Page 13 2.2.6 Cable Type The PWR-AVIS jacks are designed to accept patch cords made up of 735A type mini coaxial cable equipped with little coax plugs (LCP). Equipment (IN and OUT) cable is dependent upon service or bandwidth of the associated equipment. Video equipment requires 734S1 or equivalent cable, equipment operating at intermediate frequencies (IF) and radio frequencies (RF) require HEC-2 or equivalent type cable.
