Installation COMtrexx Flex
Warning: Power surges, which may occur during electrical storms, can cause life-threatening electric shocks, or damage or destroy the PBX.•Do not touch the PBX or any equipment connected to it during a thunderstorm.
•Hire a qualified electrician to lay the cables within the building – including the cable to the door terminal.
•Do not use the a/b ports to connect remote extensions.
Warning: Touching voltage-carrying conductors or telephone connections can cause life-threatening electric shocks. The PBX also contains hazardous voltages outside the power supply unit (e.g. ringer voltages). Work on active, contact-hazardous parts is only permitted after a voltage-free condition has been established. Working near active parts is only permitted if these parts are voltage-free or protected against direct contact.•Pull out the PBX's power plug before instructing a qualified electrician to open the casing to install the expansion module, or switch or connect equipment. Also disconnect the devices from additional power sources (e.g. UPS, if installed).
•Wait at least 3 minutes for the capacitors in the unit to discharge.
Important: Improper use may, for example, cause functional restrictions or malfunctions, the destruction of the device or, in a worst case scenario, personal injury.•Only connect equipment that is compatible with the proper use of the PBX.
Installation Instructions
The PBXs are intended to be operated in closed rooms. In addition, all of the devices connected to the system must be located in the building.
The PBXs enable you to connect some devices directly, inasmuch as they are close enough to the PBX. The distance depends on the length of the equipment connection cables up to a maximum of 10 m.
If no suitable connection sockets are available or are too far away, you must lay the installation cable permanently. Use installation cable (e.g. J-Y(St)Y 2x2x0.6) with the following characteristics:
•unscreened, but screened if conditions are unfavourable, for example, near a strong transmitter or an electrical power line
Analogue: Prevent interferences. Avoid laying long lengths of parallel lines, especially next to the mains. Twist the pairs.
Accessories and service parts can be bought at specialised stores.
Ethernet Port
Requirements:
•For Internet access: Broadband Internet connection (e.g. DSL router, TV cable router)
•Existing network (LAN) or single switch (for VoIP terminals) with a data transmission rate of 100 Mbit/s
Note: For VoIP data communication in combination with the transmission of additional data (e.g. downloads), we recommend a data transmission rate of 100 Mbps. For a reliable support of 100 Mbps, you need cables and wall sockets of at least Category 5 (CAT 5). For a reliable support of 100 Mbps, you need cables and wall sockets of at least Category 5 (CAT5).Note: When using a switch with PoE function, a separate power supply (e.g. via a power plug) is not required for connected VoIP telephones, always provided they support PoE.•For the use of DiffServ for prioritising language packages: DiffServ support of all active network components is available and enabled.
•NAT traversal should either be performed via the PBX or with a well-functioning SIP-aware router.
Note: If the router is not SIP aware, several of the ports on the router necessary for VoIP data communication must be enabled (RTP port and SIP UDP ports) (port forwarding). A list of the ports used in the PBX can be found in the web interface of the PBX under Administration > Network > Ports.Caution: Each time a port is opened on the NAT router, this creates a potential security risk.•It is essential you put additional protective measures in place.
Important: If you want to integrate the PBX into an existing network, contact the responsible system administrator. Making changes to an existing network may cause considerable malfunctions.Analogue terminals
A wall socket (RJ-11 or, within Germany, TAE) must be connected via a fixed laid cable with the terminal clamps of the internal analogue port.
Connection options: •Analogue telephones •Analogue fax devices •Analogue answering machine •Modems •a/b audioboxes •a/b door terminals (e.g. TFS-Dialog 200/300/400, TFS-Universal plus, TSA a/b | |
