Tekelec 959-5021-01 Controller Module

The Tekelec 959-5021-01 Controller Module is a plug-in PCB that delivers SS7 link interface control and signaling processing for Tekelec EAGLE carrier-class signaling transfer point (STP) systems. Manufactured by Tekelec (Oracle Communications), this controller module is designed for use in Tekelec EAGLE STP platforms, telecommunications central offices, and carrier networks requiring high-availability voice, data, and signaling services, and it pairs with the LIC286E Link Interface Controller (assembly 850-2861). This legacy/discontinued module serves repair, replacement, and maintenance tasks for legacy carrier-class equipment and is commonly replaced by Tekelec 850-2861, 850-0144, or 959-5047 across SS7 signaling networks, carrier switching systems, mobile and fixed-line networks, and broadband infrastructure.
