FAQ

Q1: Can the number of Ethernet channels be customized?

A: Yes. Standard models support 1/2/4/6 Ethernet ports; additional customized mappings are available upon request.

Q2: Does the device support mixed balanced and unbalanced E1 wiring?

A: Yes. Both 75Ω (BNC) and 120Ω (RJ45/DB37) options are supported; selectable at order build.

Q3: What’s the longest supported transmission distance?

A: Up to 120 km with appropriate singlemode optics and fiber quality.

Q4: Is dual power input supported?

A: Yes. AC + DC or dual DC redundancy builds are available to enhance reliability.

Q5: Can it interoperate with other vendors’ PDH equipment?

A: The E1 interface follows ITUT G.703 and related standards, enabling interoperability with most carriergrade PDH systems.

Q6: Does it support inservice maintenance or hotswappable optics?

A: Many configurations support fieldreplaceable optical modules; please confirm hotswap capability for your selected chassis revision.

Q7: Is Ethernet traffic switched or just transported?

A: Default models provide transparent Ethernet transport (mapping over PDH/optical payload); valueadded switching models available per project request.
