Description of the card
The LD4 card has four T0/S0 interfaces and is used to manage 2- or 4-channel DECT base
stations.
There are two possible configurations:
Without ADPCM daughter card:
connection to the ISDN network, ISDN terminals or connection of two-channel DECT base
stations.
With one (two) ADPCM daughter card(s) or one ADPCM 16 daughter card:
used to connect 4-channel DECT base stations to one to four of its interfaces; the other
interfaces can be connected to the ISDN network, ISDN terminals or 2-channel DECT base
stations.
Fitted with one or two daughter cards, the LD4 card uses the TSs assigned to 2 slots, hence
forbidding equipment sharing the same PCM in the associated slot.
