CA2.1
(VALH)
Function
ON CA2.1 is active only in Shelf 0 in the main cabinet (positions 0-5).
Set it to ON if the LD4 card is used in T0 mode, to synchronise the PBX clock
with the public network clock.
OFF Set to OFF:
- if the LD4 and LD4N cards used in T0 or LT2 are in positions 2 and 4
because they cannot simultaneously transmit the clock ("or" cabled),
- if the LD4 and LD4N cards used in T0 or LT2 are in positions 3 and 5 (the
PBX has only four clock inputs). These positions 3 and 5 correspond to the
priority clock input of the OCT3B or OCT4 CPU.
Case of LD4 in S0 configuration (for DECT BS)
