Typical Adpcm Card Redundancy - Zhone IMACS 8000 User Manual

Running Head
ADPCM Card Redundancy
The System Main Screen now looks like Figure 5-83. The status of all ADPCM ports of the
card in slot P1 is "r".
If the card in slot P2 or P3 fails, the entire voice compression network will switch to the
redundant card in slot P1. When the Out of Service condition is repaired, the ADPCM card in
the slot that previously failed becomes the redundant card for the system.
The system does not require any ADPCM cards to be redundant. All three slots (P1 to P3) can
be used for normal traffic on ADPCM voice networks.
