FAQ

Q1: How many voice ports can the OTS-MSE4-MINI support?

A: The chassis provides 8 plug-in slots; actual FXS/FXO/magnet/hotline port counts depend on the mix of interface cards installed. Contact us with required channel quantity.

Q2: Are the 4 Ethernet ports really isolated?

A: Yes. Each 100M port is hardware-isolated to enhance traffic and security domain separation when sharing an optical uplink.

Q3: What is the maximum optical transmission distance?

A: Up to 120 km with the appropriate optical module and fiber budget selection.

Q4: Does the unit support both FXS and FXO on the same chassis?

A: Yes. Mixed interface cards (FXS/FXO/magnet/hotline) can be installed in the available slots.

Q5: Can I monitor device status remotely?

A: Basic local LEDs are standard. Remote management options vary by build; please inquire if SNMP/Web management is required.

Q6: Is DC power available?

A: Standard build is AC 220V. A DC –48V option or dual-power customization may be available—confirm at order time.

Q7: Can this unit interoperate with other vendor E1 or voice transport gear?

A: E1 complies with ITU-T G.703/G.704, and voice encoding follows G.711/G.732, enabling broad interoperability.
