2.5.2 Poles 1- 4
Pole 1 - (default ‘OFF’, providing auto re-set of the Alarm port to 2400
bit/s, and the Command port to 9600 bit/s during reset after a power
failure) in the ‘ON’ position sets both the Alarm and Command ports to
2400 bit/s upon reset.
Poles 2 & 4 - Are not Used.
Pole 3 - Must be ‘ON’ for all UK and European ISDN applications, where
‘Power Source 1’ detection is a regulatory requirement. Where ‘Power
Source 1’ is not provided, pole 3 must be ‘OFF’.
Presence of ‘Power Source 1’ is where 40V DC power is applied by the
network between the transmit and receive ‘S’ bus pairs. Enabling power
source detection (pole 3 ‘ON’) means that line power must be present
before calls can be made or received.
All DIP switches will be set during manufacture and must not be
changed.
It is possible that a designated “country” variant could be used in another
country if approvals in that country permit it.
The variant that is set can be read by using the
‘VERSION’
command.
If a KBU 64 is upgraded with later software, please contact your local
Technical Support organization for further information.
