PABX Description
The PABX system is an ISDN telecommunications system at an ISDN point-to-multipoint or point-to-point connection that employs the
Euro ISDN protocol (DSS1). Analog terminal devices can be connected via integrated jacks. The PABX system is also equipped with an inter-
nal ISDN port, allowing an ISDN terminal device to be connected at its RJ45 jacks. Fixed cabling using terminals is also possible for analog
connections. Two analog ports are routed out via a common RJ45 jack. Assignment of internal phone numbers is freely configurable bet-
ween 00... 99. Calling using analog terminal devices should be conducted using the DTMF method and these devices should be equipped
with a Flash key. Analog terminal devices that use pulse dialing can not be used for functions or codes.
Please note that the buttons on some ISDN terminals available on the market may limit the use of the features provided by the PABX system.
All terminal devices connected to the system must be »TC Terminals Guideline« or »R&TTE Guideline« approved.
The PABX system also provides all of the functions necessary for high-speed Internet access for a single pcs, or for complete LANs via xDSL
or ISDN. Here the firewall integrated into the PABX system, together with the NAT (network address translation) function, provides the ne-
cessary security; the functions DHCP server and DNS proxy ensure that the scope of configuration, both for your PABX system and your PC,
is kept to a minimum.
Internet access for all of the PCs connected to the PABX system is provided via one single connection (SUA - single user account); only one
set of access data is required from your Internet service providers (ISP.
Loss of power
During a loss of power you can initiate or receive calls at an ISDN or system telephone capable of emergency operation. Other telephones or
terminal devices can not be reached as long as power is down.
In the event of a loss of power, all stored contents (program and application data) are retained in the PABX without any changes. The inter-
nal clock for the phone system is set automatically via the ISDN port on the next external call.
Cleaning
You can clean your PABX without any difficulties. Use a slightly moistened cloth or an anti-static cloth for this. Do not use any solvents! Ne-
ver use a dry cloth; electrostatic charges could damage the electronics in the system. Always ensure, however, that no moisture penetrates
into your PABX, as this could result is damage to the PABX.
Safety notes
Important safety information for handling the PABX system
·
Unauthorized opening of the PABX and improper repairs may result in risk of injury for the user.
Attention: Unplug the 230 V AC plug-in power supply before removing the enclosure cover of the PABX and working
on the cable terminal bay. Replace the top on the PABX before plugging the power connector back in.
Plug the plug-in power supply unit into the 230 V ~ socket so that the connecting cord to the PABX system points
downward.
·
Do not expose the inside of the PABX or the plug-in power supply to any liquids. This would pose a risk of electrical
shock and can also destroy the devices.
·
You should not connect or disconnect any lines during thunderstorms.
·
Only terminals with SELV and/or which comply with ETS 300047 may be connected to the PABX system. This regu-
lation is fulfilled when approved terminal devices are used as intended.
·
The distance between the plug-in power supply unit and the PABX and to the ISDN connection should not exceed 1.
5 meters so that standard connecting lines can be used.
·
The PABX is operated with 230 V AC using the plug-in power supply unit. Please ensure that the electrical outlet
(grounding outlet) for the PABX (and for additional devices where required) is installed such that it is freely accessi-
ble at all times and that it is installed by a qualified electrician to prevent any risks of personal or material injury/da-
mage! Where at all possible, provide a separate power circuit for the 230 V connection of your PABX system. This
protects your PABX from short-circuits that may occur in other in-house equipment.
