Dispatching voice is different from surfing the Internet. It pays attention to pick-up and call at any time, and it is stable and does not drop calls. PCM telephone optical transceivers can be used to converge multiple analog telephones to the computer room through an optical fiber. This is the most common method for voice transformation in sites and campuses.

Connection between program-controlled exchange and extension

The dispatching computer room is generally connected to a program-controlled or IP switching host, and the user side is connected to an ordinary analog telephone.8-way telephone + 1-way Internet phone optical transceiverProvides 8 telephone channels, directly replacing copper cable subscriber lines, and pulling 8 extensions through an optical fiber to a duty point or guard box several kilometers away. Signaling such as on-hook and ringing is transparently transmitted, and the call experience is close to local direct connection. For old computer rooms that have used program-controlled switching, the original wiring will be almost unchanged in this way, and only the user lines will be replaced with optical ports.

Division of labor between voice and data

The same model comes with 1 network channel, which can carry dispatching station data or office Internet access: voice uses PCM to ensure real-time performance, and data uses Ethernet. The two do not occupy each other's bandwidth. When there are many remote extensions, multiple devices can be uploaded to14-slot box transceiver rackCentralized power supply and unified management make the cabling on the computer room side neater, making it easier to label and create ledgers. When multiple simultaneous calls are needed, you can first estimate the number of channels based on the peak traffic, and then decide how many devices to connect in parallel.

Power supply and reliability

• The computer room side and the remote end are supplied with stable DC power supply respectively, and surge protection and single-point grounding are installed in the mine area.
• It is recommended to reserve a backup route or a copper wire for key dispatch extensions.
• Test the on-hook, ringing and call clarity channel by channel before activation to avoid incomplete signaling on individual channels.

The value of telephone optical transceiver is to turn voice into a plug-and-play dedicated line; Wolflight has this series in stock and supports customization according to the number of channels. Before voice transformation, it is recommended to plan the number of extensions before deciding on the model.
