F6-F6/F6 or F6-F6/F1 contiguous multi-site configuration in
duplex mode
The two "Master" PBXs are connected via their primary port. The secondary ports of the “Master”
PBXs are connected to the primary ports of the “Slave” PBXs.
The base stations must be wired in two pairs. The synchronization signal is carried by the M bit in
the S frame.
Note:
If the DECT base stations are connected to the integrated S0 accesses of the
NeXspan S CPU card, a third pair is required for synchronization.
Note:
The LD4X mode (removing the J14 jumper on an LD4NX card and used to implement
additional functions) is only compatible on NeXspan L/S with software release R4.1 and
above.
Note:
At least OCT4 card equipped on the F1
