Dialogic® ISDN PRI Redundant I/O Card - LNX-PIO-1000

Description

The Dialogic® 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.

Active or Switchover Mode

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.

Placement

The I/O card resides in the rear card slots of a CSP 2090, CSP 2110 or CSP 2040 chassis.

Configuration Information

The part number, serial number, model number, and revision are located on the back of the board.
