FAQs

Q: Does this cable work with the MSR T3/E3 SIC?
A: Yes, it converts the SIC port to standard dual-BNC 75Ω Tx/Rx for DS3/E3 handoff.

Q: Is this suitable for long-distance runs?
A: No, it is intended as a short patch cable to a CSU/DSU or telco demarc. Long-distance spans are provided by carrier plant.

Q: What coding and framing does it support?
A: The cable is passive; the SIC handles B3ZS/HDB3 coding and common DS3/E3 framing.

Q: Do I need any adapters for dual-BNC?
A: No adapters are required if your CSU/DSU or demarc provides standard 75Ω BNC ports.
