    I just installed the NM-4T 4 port serial board on my 2621 router.

    but when I do "show interface", I only see two fastethernet interfaces
    and not the newly installed serial board.

    is there any extra setup i need to do to make it working?

    could it be faulty board?

    Thank you for your help

    Thanks for the reply.

    Then what kind of serial interface is supported on 2621 router?

    I wanted to use that 2621 router as frame relay cloud for my lab.

    Can I use the 4 port async serial port then?

    Thank you again

  4. WIC-1T/WIC-2T are supported. And are very cheap.
    Weren't you the one that had the 3620 that was going to do the NM-4AS?
    Or was that somebody else?
    Err, I wouldn't recommend it, Frame-Relay really wants to use the
    synch serial ports.

    Thanks for pointing this out, would never have occurred to me
    and I may be building a lab quite soon. Unless of course I
    decide than Dynamips will do the job for me. I do have a lot of
    Cisco hands on so I think I will get away with it.

    Merv of course means wic-1t and wic-2t.

    WIC...T1 is something a bit different:)
