    Having an issue with my frame lab.

    Setup is like this:

    [2611frame customer]<=====>[3640#1 frame switch]<=====>[3640 #2 frame
    customer]

    LAB SETUP

    Equipment:

    All 3 are connected together by 3 foot T1 crossover cables

    2611 (frame customer #1)

    !!clock is set to line!!

    interface Serial0/0
    no ip address
    encapsulation frame-relay IETF
    frame-relay lmi-type ansi
    !
    interface Serial0/0.1 point-to-point
    bandwidth 1536
    ip address 192.168.1.2 255.255.255.252
    frame-relay interface-dlci 501 IETF

    The issue is this:

    My PVC's are bouncing. The interface is up on the customers but the
    line proto keeps bouncing.

    Any thoughts??
