FAQs

Q: Is this SPA channelized?
A: No. It is clear-channel T3/E3. For channelized applications, use a channelized T3/E3 SPA variant.

Q: What cable type is required?
A: 75Ω coaxial cable with BNC connectors (separate Tx and Rx per port).

Q: Can I mix T3 and E3 on different ports?
A: Yes. Ports can typically be configured individually as T3 or E3 (platform support required).
