"Master" and "Slave" mode:
The synchronization ports work in the following modes:
• "Master» mode: the signals from the secondary port transmit the 2.048 MHz bit clock and
reference DECT synchronization from the "master clock" CSI board to a PBX in slave mode.
• "Slave" mode: the 2.048 MHz bit clock and DECT synchronization are received from a
synchronization port of the PBX in master mode and synchronise the CSI boards connected
to the BCSI.
The use of "Master" or "Slave" mode is automatically configured by the BCSI board (if a clock is
detected on the primary port, slave mode is used).
The secondary port of the master or N slave is connected to the primary port of the first slave or
slave N+1.
Note:
the maximum connection cable length from one port to the other is 600 m.
8.5.2 Configuration
The default (factory) configuration of the switches on the BCSI board is as follows:
CA1 and CA2 = ON
Binary value: ON = 0 ; OFF = 1
Figure 7-14: Default configuration (factory configuration) of switches CA1, and CA2 on the BCSI board
Configuration on "Master" PBX:
• The type of PBX downstream of the "Master" must be indicated (F1/F6 or F4, manual
configuration). A switch (screen printing: GAVF1/6) on the BCSI is used to define the type of
PBX downstream:
• GAVF1/6 set to ON: defines an F1/F6 PBX downstream
• GAVF1/6 set to OFF: defines an F4 PBX downstream
• Check the configuration of switches CA1, CA3 and CA4 on the CSI card. Their configuration
must be the same as the factory configuration (see mono-site synchronization, Section 5.4).
• Check the configuration of switches CA1, CA2 and CA3 on the RMH cards (see single-site
synchronization, Section 5.4).
