FAQ

Q1: How many telephone lines does the OTS series telephone optical terminal support? Does it support mixed interfaces?

A1: It supports telephone interfaces from 1 to 32 or more, and can be mixed with FXS, FXO, magnet, hotline, etc., and supports simultaneous transmission with Ethernet and RS232.

Q2: Does it support single-core optical fiber transmission? How far can it be transmitted?

A2: It supports single-fiber/dual-fiber transmission. When using WDM technology, it can transmit in both directions with single fiber. The transmission distance can reach 20km/40km/80km/120km depending on the optical module.

Q3: How is the equipment powered? Does it support dual power supply?

A3: It supports two power inputs, AC 220V and DC -48V. It can be configured to switch between dual power supplies automatically to ensure stable operation of the device.

Q4: Does it support Ethernet redundancy or bandwidth aggregation?

A4: Some models support 2-way Ethernet, with physical isolation, and can choose to bind transmission (support up to 3.84Mbps) or independent isolation transmission.

Q5: Is the device installation and maintenance complicated?

A5: The device is modularly designed and plug-and-play; the panel has complete indicator lights for easy status judgment, and can also be remotely managed, making maintenance simple.
