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. A variety of active and passive jack access cards provide
various amplification and monitoring levels. The jack access card mates with a rear interface
unit (RIU) that is mounted in the chassis. A rear interface unit provides the interface for
permanent coaxial connections (F or BNC) to network elements (NE) (see Figure 1).
Note Jack access cards are used in the RIU only for testing or troubleshooting functions.
The number of access cards required in an office must be determined and ordered by the
user based on expected provisioning and maintenance activity.
The PWR-AVIS chassis contains one or two power supplies (depending upon configuration)
and wiring for powering amplifier and active jack access cards.

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.
The PWR-AVIS chassis contains 17 RIUs (one for test) in which LCJ jack access cards or
amplifier cards are installed. Two slots are located at the front of the chassis for installing one
or two (depending upon configuration) power supply module(s). Office power connections for
the power supply module(s) are made, as required, via two sets of -48V and RET terminals at
the rear of the chassis. An AC to -48VDC power adapter (PWR-AVIS-110-ST) may be used
when a -48VDC power source is not available. A cable management tray at the rear of the
chassis supports the IN and OUT cables from the Network Elements.

Power Supply Module
The power supply modules slide into slots labeled PWR 1 and PWR 2 at the front of the
chassis (see Figure 4). This DC to DC converter provides the necessary +5V power for the
chassis. A green LED at the front of the power supply module, when lit, indicates that the
power supply module is functioning properly.

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.) The
jacks also provide patching functions to bypass defective equipment and/or isolate problems
in circuit links. The monitor jack is non-switching. Patching into this jack does not break the
circuit and allows non-intrusive access. The unity gain (baseband video) card provides a 0 dB
level at the monitor jack. The IN and OUT jacks incorporate a “make before break” switching
design and self-terminate into 75-ohms to ensure high service performance without
interruption. The IN switching jack provides access to the input signal of an NE. Patching into
the jack opens the circuit and signals can be inserted for testing or patching to bypass
defective equipment. The OUT switching jack provides access to the output signal of an NE.
Patching into the jacks opens the circuit and signals can then be extended for testing or bypass
functions. When patching arrangements do not extend the NE output signal, it is
recommended that an external 75-ohm termination plug be inserted into the OUT switching
jack. This provides greater signal isolation and reduces cross-talk level. The amplifier cards,
which do not have jacks for circuit access, provide fixed gain amplification of an incoming
signal by 0, 10 or 20 dB respectively for return path applications.

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. PWR-AVIS With Dual (Redundant) Power Supply Modules
Page 6
© 1999, ADC Telecommunications, Inc.
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.
2.2.2
Alarms
As shown in Figure 8, PWR-AVIS incorporates two pair of screw terminal alarm contacts
(PS1-A and B, and PS2-A and B) located at the rear of the chassis. The contacts may be used
as an interface to any existing customer-supplied alarm system. Both A and B contacts
perform the same function and can be used with two independent types of warning signals,
either audible or visual. If the power supply voltage drops below a normal operating threshold
of 3.5VDC, failure is detected and alarm(s) are triggered. The alarm contacts are normally
open and will close when a failure occurs.
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.
When PWR-AVIS is configured with two power supplies, it normally operates using the
primary power supply. If the primary power supply fails, its alarms will activate and the
secondary power supply will seamlessly begin to provide power to the chassis. When the
primary power supply begins to operate properly (after replacement or maintenance), its alarm
will deactivate and it will seamlessly override the secondary power supply. In all cases
(except where both power supplies fail) all RIUs will continue to be supplied with power.

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. The ± 5 V is passed to the jack access card through pins while the ground is
connected through the RIU and card bodies.

AVIS Jack Access and Amplifier Cards
There are three basic card circuit configurations available:
• A passive (–20dB) card with Monitor, IN and OUT little coax jacks for full jack access.
• An active (0 dB baseband video) card with Monitor, IN and OUT little coax jacks for
full jack access.
• 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. The monitor network circuitry for the active and passive cards provides access to the
signal at 0 or -20 dB level respectively. The active card provides a 0 dB unity gain signal with
respect to the output signal. The active amplifier cards provide fixed gain of 0, 10 and 20 dB
respectively and are for return path application with bandwidth of 5 MHz to 200 MHz. Power (± 5
V) and ground for active cards is automatically transferred from the RIU when the card is
plugged in. The cards with jack circuitry automatically provide 75-ohm circuit termination.

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. All cables should be 75-ohm coaxial with tinned
copper shield. The recommended maximum length of cable between NEs is shown in Table 1.
Cables are available with F or BNC connectors factory pre-terminated on one end and a stub
end on the opposite end. The stub end can then be field connectorized using the appropriate
connector to fit the NE Interface. This method of cabling provides exact length cables and
minimizes storage congestion. If the use of pre-terminated cables is not desired, connector kits
with installation procedures are available from ADC for field termination.

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 2.0 inches (5.0 cm) out in front of the
rack. Mounting screws, reversible mounting brackets, designation labels and cable
management tray are shipped with the chassis.
The cable type used for the NE IN and OUT circuits is dependent upon application, type of
service and equipment. All cables should be 75 ohm coaxial with tinned copper shield. The
recommended maximum lengths are from NE to NE. See Figure 11.

4. Dress each coaxial cable across the rear cable management tray. Follow local practice
regarding the use of lacing cord or tie wraps for securing the cables to the tray.
5. Measure the length of cable from the cable management tray to the designated RIU,
allowing slack for tension relief. Cut, strip, and terminate each coaxial cable with an
appropriate F or BNC coaxial connector. Instructions for terminating coaxial connectors
are included with the connectors.
6. Record the NE assignment on the designation label located on the inside front door of
the chassis.
