How to install an EPABX system?
Installing this system has some pre-requisites. These include choosing an ideal place, configuring and designing the lines through connection diagrams, and wiring.
Installation of the key service unit is the first thing to take care of. KSU is the CPU of the system and it must be connected to all the telephones and lines working on the system. An electric screwdriver and a proper mounting kit are needed to affix the unit. The unit should be mounted on the wall to protect it from harsh conditions. And an electric drill is needed to initiate the setup.
The next step is to plug in the circuit cards. These are important for facilitating communication and voicemail services. They are to be inserted in the sides of the KSU, with numbered slots.
Now you can connect the telephones to the KSU with the help of phone cords, provided by the company. After the installation, turn on the KSU to verify its setup and keep in mind that all lights should be turned on. If any light remains off, your setup is incomplete. The verification moves to the telephones now. Turn on the telephones and check if they are all connected to the KSU.
Then the units are coded or numbered to provide extensions and this is done by following the manual properly. Documentation of these codes is necessary for future reservations. At last, make phone calls externally and internally to test the service, and contact the vendor in case of complications.
In a nutshell
Installation of an EPABX system is tedious and time-taking, but if you follow the manuals explicitly, it can be done successfully.
