Table 1-3. ADPCM Card Setting Options and Defaults
STATE
The State setting determines whether the port is active or inactive. When assigning ADPCM
engine pairs for WAN traffic, set the State setting to stdby (standby) for ports that are not yet
used or not yet configured. Set it to actv (active) for ports that are ready for use.
Setting the State to rdnt (redundant) for any port on an unused card will cause that card to act
as the redundant back-up for all of the other ADPCM cards in that unit. Once a card is
designated as a redundant ADPCM card the only way it can be used for regular ADPCM
traffic is to change the state of the selected port back to either actv or stdby.
When assigning ADPCM engine pairs from user cards, changing the port from stdby to actv
and saving the selection information on the user card screen will cause the system to
automatically assign an ADPCM engine.
When the engine is assigned from a user card, no changes can be made from the ADPCM card
screen to any of the fields.
