ISDN PRI Redundant I/O Card - Model No. LNX-PIO-1000
The ISDN PRI Redundant I/O card is used with two ISDN PRI cards. It provides complete redundancy by replicating all 32 D channels on a standby card.
Important! Only one I/O card is required for each pair of ISDN PRI cards.
The I/O card has no external connections. All of its features and functionality are internal to the system. A mirror image of the active card’s primary and secondary D channels is copied to the standby card.
If the active card fails or if you remove it, the standby card takes over and manages call processing. All calls in a connected state are retained while others are purged. If you reset the active card, it switches over to standby.
The I/O card resides in the rear card slots of a CSP 2090, CSP 2110 or CSP 2040 chassis.
The part number, serial number, model number, and revision are located on the back of the board.
The ISDN PRI Redundant I/O card is designed to the following electrical, physical and environmental specifications.
