Pilot Carrier Redundancy Switch

**DISCONTINUED**

ATX’s Pilot Carrier Redundancy Switch for resilient backup of pilot channels that drive performance in outside plant HFC systems.

Features

Reinserts replacement oscillator at 2 different RF output levels based on user defined threshold settings
Monitor and control of all functions through front panel or through web browser (HMS compliant, SNMP v2c)
LCD display shows current alarms and allows detector thresholds to be set
Independent, load sharing, field-replaceable AC or DC power supplies provide full power redundancy
Front panel test points for oscillator levels and combined full system output level monitoring
Measures a filtered sample of the RF input to determine when the internally generated replacement pilot carriers need to turn on
Simple 2-cable connection with highly reliable passive through path
1 or 2 pilot channels chosen at time of order will define the fixed filter and oscillator frequencies
Field-upgradeable and swappable pilot carrier filters and replacement oscillators

HUMIDITY	5-95% (without condensation)
DIMENSIONS	1RU, Rack Mount: 1.75”H x 19.0”W x 17.0”D (4.45H x 48.26W x 43.18D cm)
WEIGHT	9.77 lbs (4.4 kg)

NOTE:

(1) For pilot channels ≤ 500 MHz: input detection level noise floor is 23 dBmV.

For pilot channels > 500 MHz: input detection level noise floor is 25 dBmV.

Ensure reference level is high enough that hard fail threshold does not go below these values.

Part Number	Description
PCR-OSC-xx(1)	Replacement Oscillator (xx = oscillator frequency in MHz)
PCR-NBP-xx(1)	Replacement Narrow Bandpass Filter (xx = filter centre frequency in MHz)

NOTES:

(1) For non-frequency agile versions of PCR-SW. Can be ordered separately as backup modules or to change frequency of source and detection.

Both OSC and filter required and must be same frequency as each other to function.
