FAQs

Q: Which cables do I need for V.35 or X.21?
A: Select the matching Smart-Serial breakout cable for the required interface, such as V.35 DCE/DTE or X.21. Use DTE or DCE versions based on your clocking design.

Q: What protocols are supported?
A: PPP, HDLC, and Frame Relay are supported for serial WAN transport.

Q: Can this module provide clocking?
A: Yes, it supports both DTE and DCE modes with internal or external clock sources.

Q: Is this suitable for higher-speed links like T1/E1?
A: This module targets synchronous serial interfaces; T1/E1 requires the appropriate dedicated interface module.
