F1/F2/F4 Or F6/F2/F4 Contiguous Multi-Site Configuration - Aastra X series Installation And Implementation Manual

8.6.3

F1/F2/F4 or F6/F2/F4 contiguous multi-site configuration

The slave PBXs must be synchronised via inter-site links (2.048 MHz clock).
The base stations must be wired in three pairs (F2 has no synchronization port + LD4/LDS,
LD4NX/LDS combination). The synchronization pair carries the 800 ms clock.
Note: F2 has no synchronization ports; so for a multisite configuration between an F2-F4 fitted
with FPHBG/CSH or an F2-F4 fitted with FPHBG2/CSI/BCSI, the configuration of the
multisite synchronization is the same.
Note: The LD4X (removing jumper J14 from an LD4NX card and offering additional functions)
is only compatible on the NeXspan S/L/D range and as of software release R4.1.

(1)
: use a repeater if there are more than 5 slave base stations
(2)
:even in an IP multi-site network, as the IP network is not synchronising, the PBXs must be
connected by a synchronising inter-site link.
