Connecting the clocks
Cable HG4302X is used to connect the DECT clock (800ms). This clock exits on 3 different V11
pairs (see LDS, LDT interfaces). All DECT V11 clock connections should be carried out on the
4G terminal strip.
• Incoming (slave card)/outgoing (master card) DECT clock: SYNP (polarity +), SYNN (polarity
-).
• Outgoing DECT A clock: SYNAP (+), SYNAN (-).
• Outgoing DECT B clock: SYNBP (+), SYNBN (-).
If LDS (and/or LDT) cards are connected in the same PBX, it is advisable to use the PCM
jumper.
If LDS (and/or LDT) cards are connected in a multi-site network, it is advisable to use an L904
cable.
