FAQs

Q: Which cable do I need for this serial port?
A: Use a Smart Serial transition cable that matches your peer interface and role, e.g., Smart Serial to V.35/X.21/RS-232/449 in DTE or DCE variants.

Q: What protocols are supported on the link?
A: Common serial WAN encapsulations like PPP, HDLC, and Frame Relay are supported (specific features depend on router IOS and platform).

Q: Can this be used as a console port?
A: No. This is a WAN serial interface, not a console/management port.

Q: Which routers are compatible?
A: Select Cisco ISR platforms with HWIC slots. Check your router’s hardware guide for HWIC support.
