ADPCM Card Redundancy

5.31 ADPCM Card Redundancy
The Integrated Access System can also have ADPCM cards, which use voice compression
technology to effectively increase the digital voice transmission capabilities of voice cards
(E&M, FXS, or FXO) or WAN links. See Server Card Reference Guide for more information
on the ADPCM card.
Each system can have up to three ADPCM cards in slots P1 through P3, depending on slot
availability. In systems with two or three ADPCM cards, any of those cards can be selected as
the redundant (backup) card. There are no restrictions on chassis slot order.
Figure 5-81 shows a system with three ADPCM cards. The ADPCM card in slot P1 is
highlighted. Pressing <Enter> will bring up the ADPCM Main Screen shown in Figure 5-82.
