Part Number: 880160 The CPU-3 XCON card controls the integrated access system. It initializes the system upon power-up, and runs a self-test on all cards plugged into the chassis at that time. The card polls all cards in the system every second to determine their operating status. The card also processes all incoming operator commands and displays the responses in a series of operator interface screens for each card in the system. The operator interface system (local VT-100 terminal, remote computer, or network management system) connects to the Interface card, which sends these commands to the CPU card for processing. The card's circuitry allows you to cross-connect DS0 time slots between T1 and E1 lines connected to the system WAN cards. Included are test pattern generators for T1 and E1 line test purposes. Finally the card performs master-slave CPU arbitration. In a system with redundant CPU cards, the two CPU cards communicate their status to each other. If the master CPU card fails, the redundant card takes over and becomes the master. ## Images - - -
