Low Speed Protection Card
Overview
The Backup Card
A Quad T1 or Quad DS1 ADPCM service card can be configured as the “Backup card”. The Backup card provides T1 port protection for other installed T1 service cards, and can occupy any one of the eight service card slots.
Note: It is imperative that the slot designated for the backup card have NO wire- wrap connections.
Protected Cards
The Quad T1/Quad DS1 ADPCM service cards to be protected can occupy any of the 7 remaining service card slots (backup card occupies the 8th slot). One or all four ports can be protected, though each series of ports (all 1s, 2s, 3s and port 4s) have one backup T1 port. The Axxius system can use other service cards in any of the 8 service card slots without interference with the Low Speed Protection system.

Priorities can be set for these protected ports
