CONFIGURATION

Note: The minimum reference of the LD4 card is HJ4054AD02.
4.3.2.1 SWITCH SETTINGS (COMPONENT SIDE)
Two jumpers (SW7 and SW8) are used to select the remote power supply voltage (48 V
DECT base station or 40 V ISDN line interface circuits). The 48 V is supplied by the PBX
back panel while the ISDN 40 V is supplied by a 2-pin stocko connector fitted to the LD4
card face plate.
! ! ! !
Use 48 V remote power supply with DECT radio base stations. The use of 48 V
remote power supply is mandatory with S0 sets.
Two jumpers per ADAPT channel are used to set the adaptation resistors on the Tx/Rx
pairs. For DECT, these jumpers must be set to the ON position.
Power supply switches (ALIM), SW3, SW4, SW5, SW6: when connecting a 2-or 4-channel
DECT base station in S0 mode, the two jumpers must be configured to allow remote
powering of the access from the PBX.
Programming jumper (PROG) must be set to 1-2 (as delivered from the factory) to prevent
permanent damage.
