FAQs

Q: What differentiates the E-chassis from non-E models?
A: The E-chassis provides higher overall system performance and greater service-module capacity, making it suitable for denser voice and routing deployments.

Q: Can I expand the number of CUBE sessions?
A: Yes. Additional CUBE session licenses and adequate DSP capacity are required for scaling beyond 25 sessions.

Q: Is LTE supported?
A: Yes, via a compatible cellular EHWIC module (not included).

Q: Does it support traditional TDM trunks?
A: Yes, by adding appropriate VIC/VWIC cards for T1/E1; analog FXS/FXO is also supported with the right modules.

Q: Is Cisco SD-WAN available on this platform?
A: No. It supports traditional IOS routing and WAN features rather than Cisco SD-WAN.
