FAQ

Q1: What is the maximum multi-service capacity of OTS-MSE8-16E1?
A: Up to 32 FXS/FXO (or magnet/hotline) + 16 E1 + 8 × 100M Ethernet channels.

Q2: Are the Ethernet channels really isolated?
A: Yes. All 8 Ethernet ports are physically isolated at the hardware level, even when multiplexed over the same fiber, helping enforce security domain separation.

Q3: How does the optical 1+1 protection work?
A: Two fiber ports operate in a protected pair; if the working fiber fails, traffic automatically switches to the standby fiber with minimal interruption.

Q4: What is the longest supported optical reach?
A: Up to 120 km (optical budget dependent—select appropriate optics when ordering).

Q5: Does the unit support caller ID and legacy telephone types?
A: Yes. It supports FXS, FXO, magnet, and hotline interfaces, with caller ID capability.

Q6: Can I mix AC and DC power?
A: Yes. The chassis supports dual input (e.g., AC + DC redundancy) depending on configuration.

Q7: Which standards govern the E1 interface?
A: The E1 ports comply with ITU-T G.703 / G.704, and jitter performance meets G.823 requirements.
