Teledyne Q-NET PDQS 1:N Redundancy Switch

Overview

Q-NET™ PDQS 1:N Redundancy Switch 1 OF 2 207823 Issued September 2021 Paradise pioneered the very first satellite modem redundancy sys- tems in the industry many years ago. Now fully re-engineered for our Q-NET satellite network solution, the PDQS 1:N Redundancy Switch protects up to 16 traffic modems that can all be running completely different services (IF, L-band, different terrestrial inter- faces, different waveforms, etc.). It keeps the backup modem sep- arate from the redundancy switch, allowing hot-swapping in the event of either a redundancy switch or backup modem failure. The backup modem can be any QFlex-400, QMultiFlex-400 or Q-Lite modem’s The redundancy switch can be used to protect both point-to-point and point-to-multipoint services. In the case of the QMultiFlex- 400, it can protect up to 16 shared outbound services and up to 128 inbound services at the same time, ensuring extremely high system availability for very little extra expenditure. It requires a P3717 1:N interface card to be fitted inside the back- up modem, plus an umbilical cable that attaches between the mo- dem 1:N card and the redundancy switch for control purposes. When fitted with the 1:N card, any production modem will automat- ically function not only as a normal traffic modem but also as a controller for the redundancy switch.
