Description of the card
This card provides the 32 kbit/s ADPCM encoding/decoding function that enables multiple
simultaneous calls on the same base station; it also provides echo damping and cancellation
functions.
This card uses the J5 or J6 connector on the LD4 card.
The ISDN cards that support the ADPCM cards enable the connection of two 4-channel DECT
base stations.
