What are the E1 network modules/interfaces supported by c1841?

Is there a link to for quick reference in general?

Show version on a c1841 indicates that it has 1 Channelized E1/PRI port.

What could be the corresponding module?

Is it NM-1CE1U, NM-1CE1B or something else?

This link has much good information about the 1841:

and if you look in table 6 it lists the various modules (including E1s) that are supported on the 1841.

Hi Richard,

Thanks for the link.

Can you comment on my second query as well please? Is there a way to identify the corresponding module with "sh version" or otherwise?

OK I'll provide the answer myself.

show diag says that it has a VWIC-1MFT-E1 (Multi-Flex Trunk WAN) module.

According to table 6 this module has data only support on c1841.
