ADCP-61-814 • Issue 1 • April 1999 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.
ADCP-61-814 • Issue 1 • April 1999 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. Circuits are accessed via little coaxial jacks (LCJ) mounted on jack access cards.
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 is shown in Figure 2.
ADCP-61-814 • Issue 1 • April 1999 2 DESCRIPTION 2.1 Physical 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. Hinged plates on the chassis mounting brackets provide an area for recording circuit identification.
ADCP-61-814 • Issue 1 • April 1999 Note: If using the single power supply option, the module should only be inserted into the PWR 1 slot. Figure 4. Power Supply Module 2.2 Functional Description PWR-AVIS provides a central jack access point between network elements (NE). See Figure 5 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.

ADCP-61-814 • Issue 1 • April 1999 2.2.1 2.2.1.1 Powering Options Single (Non-Redundant) Powering The single or non-redundant powering option provides one power supply module for powering the RIUs. Figure 6 shows an example of this configuration. Figure 6. PWR-AVIS With Single Power Supply Module 2.2.1.2 Dual (Redundant) Powering 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.
ADCP-61-814 • Issue 1 • April 1999 Note: PWR-AVIS units configured with the single powering option can be upgraded to redundant power by ordering an additional power supply module (PWR-AVIS-PSC). The PWR-AVIS provides two sets of screw terminal contacts (see Figure 8) at the rear of the chassis for connecting to a -48V office power supply. Alternately, a 110-48V (PWR-AVIS110-ST) converter (purchased separately) can be attached to either set of contacts. 2.2.
ADCP-61-814 • Issue 1 • April 1999 2.2.4 Rear Interface Units The RIU, mounted in the rear of the chassis, provides the interface for the coaxial cable and the jack access card which is plugged into the RIU from the front of the chassis. The interface connectors accept coaxial cable terminated with F or BNC connectors. See Figure 9. The RIU is factory wired with ± 5 V and ground for powering the jack access card when it is plugged into the RIU.

ADCP-61-814 • Issue 1 • April 1999 3 INSTALLATION Danger: To avoid the possibility of severe and potentially fatal electric shock, never install electrical equipment in a wet location or during a lightning storm. Caution: Always wear an anti-static discharge wrist strap to prevent static electric discharge damage to the Jack Access Card electronic circuitry. The PWR-AVIS chassis mounts in a 19- or 23-inch (48.3 or 58.4 cm) equipment rack. The chassis can be mounted flush with the rack, or extended 2.
ADCP-61-814 • Issue 1 • April 1999 6. Attach the designation label to the inside of the chassis front door. 7. Attach power wires, –48V and return. A second set of terminals (-48V (2) and RET (2)) is provided if a backup power source is desired. See Figure 14. 8. Attach wires from pre-existing alarm system (if any) to the alarm contacts on the power supply unit. Note: Use only the PS1 alarms if the chassis is configured with one power supply.
