Alcatel-Lucent 9R-0050-04 Bridge Control Card is a legacy control module used in Alcatel-Lucent bridge systems to govern the operation of attached bridge components. Variant designations include 9R-0050-04/C, and some listings label it as Bridge Control Card 2. This replacement card is intended for use in compatible Alcatel-Lucent/Newbridge equipment to serve as the central control component for bridging functions within the chassis.
