Working of T1/E1 interfaces without CME

[Zhomart Asken]

Hi everybody. I have a question about T1/E1 interface on cisco router. Is it gonna work properly if we don't have CME or SRST license enabled on router?

[bernhardczapp · Accepted solution]

yes.

CCME / SRST isn't needed for a Gateway.

You only need Router, T1/E1-Module, PVDMs

Work in what sense? As a voice gateway? Providing you're licensed for an IOS feature set that has voice, then yes.
