Wiring of a direct connection
Connection via an Active
Transmission System
For distances exceeding the range of
a direct connection, an active trans-
mission system can increase the
range to up to 50 km. Normally the
L1 master is the transmission system
for the two connected PBXs. For the
protocol layers L2 and L3, one PBX is
normally the protocol master and
the other PBX is the protocol slave.

Connection via the Public
con- Network
0
Point-to-point connections via the
public network of a network opera-
tor can be used for bridging dis-
tances beyond 50 km. Due to the
long distance involved, for technical
reasons it is not possible to synchro-
nise the L2 protocol. Consequently,
the public network is normally the
protocol master for protocol layers
L1 and L2. One PBX is therefore the
L3 master and the other PBX the L3
slave.
