Interface card
LDS/LDT cards, possibly fitted with one or two ADPCM32 (LDS) and ADPCM32B (LDT)
daughter cards are used to connect DECT base stations to a NeXspan 50.
LDS/LDT cards have T0/S0 interfaces for managing 2- or 4-channel DECT base stations. There
are two versions of each card:
•
LDSA/LDTA: 8 T0/S0 interfaces
•
LDSB/LDTB: 16 T0/S0 interfaces
LDSA/LDTA cards allow sixteen 2-channel DECT base stations to be connected, and LDSB/
LDTB cards eight 2-channel DECT base stations. 4-channel base stations can be connected by
adding one or two daughter cards: ADPCM32 (on LDS) and ADPCM32B (on LDT). An
ADPCM32/ADPCM32B card can manage eight 4-channel base stations.
Note:
The minimum technical state of the LDS card required to support an ADPCM32 card is:
HJ4094xN02
