Connecting Analogue End Devices
44
This section describes how to connect different analogue end devices to the a/b port of a COMmander 8a/b module. If at all
possible, it is determined whether the device is to be connected directly or the lines are to be laid permanently.
Warning: Touching voltage-carrying conductors or
telephone connections may cause a life-threatening
electric shock.
씮
The PBX contains hazardous voltages, even out-
side of the power supply unit (for instance ringer
voltages). Work on active, contact-hazardous
parts is only permitted after creating a voltage-
free state.
Working close to active parts is only permitted if
these parts are voltage-free or are protected
against direct contact.
씮
Casing variants for wall mounting: Pull out the
power plug of the PBX before commissioning a
skilled electrician to open the casing to install the
expansion module or perform switching or con-
necting services.
씮
If available, also disconnect the devices from
auxiliary power sources (for example, UPS).
Important: Improper use may cause, for example,
functional restrictions or interference, the destruction
of the device or, in a worst case scenario, personal
injury.
씮
Only connect equipment that is compatible with
the intended use of the PBX.
Note: For 19" casing variants, no connections are
made directly to the module itself but rather via the
connector panel on the front panel. The socket
assignments on the front panel are described as of
Page 33 .
Connecting Analogue End Devices Directly to the Internal a/b Port
Important: Connecting end devices directly is only
possible on 19" casing variants.
Requirements
– Minimal distance between the devices
Note: If the end device is placed a considerable
distance away from the PBX, the cable and the wall
sockets must be permanently installed. See
Page 44 .
A commercially-available RJ45-TAE adapter
Steps to Take
1.
Connect the end device to the telephone jacks of the
adapter.
2.
Connect adapter to the RJ-45 socket that belongs to
the internal a/b port.
Installing Cables and Wall Sockets for the Internal a/b Port
Warning: Power surges, which can occur during
electrical storms, can cause life-threatening electric
shocks or damage/destroy the PBX.
씮
Let a skilled electrician lay all the cables inside the
building.
씮
Do not use the a/b ports to connect external
private branch exchanges.
Note: For a structured cable installation configured
on one of the 19" casing variants, CAT5 cables and
CAT5 wall sockets are used instead of the cables and
wall sockets listed here. To connect an analogue
device, a commercially-available RJ-45-TAE adapter
is required.
Important: For structured cable installation on a 19"
casing variant, the line length all of the applicable end
devices must be taken into account.
Requirements
– Installation cable (for example, J Y (St) Y 2x2x0.6)
with the following characteristics:
One twisted pair per a/b port
Unscreened; however: screened for unfavourable
conditions, for example, near a strong transmitter
or an electrical power line
– A TAE jack with the following characteristics:
For telephones or combination fax/answering
machines, a single TAE jack with F-coding (a
socket labelled with an “F”)
For fax machines, modems and answering
machines, a TAE jack that also has a socket with
N-coding.
Note: Outside of Germany, use RJ-45 sockets or the
analogue wall sockets normally used in the country in
question.
