Cisco 1720 frame relay to Motorola HELP!

    I'm ABSOLUTLEY STUMPED!!! I desperately need help.
    I have a frame relay line going from out main office "Denver" to a
    remote site "Baltimore"

    My Cisco 1720 interfaces all show UP/UP status and shows LMI, but from
    its console I can't ping the Serial0.1 interface (192.168.253.250)

    On the Motorola, the config looks good and from its console I can ping
    its Serial (192.168.253.249) and it sees the circuit and everything
    looks good. It CAN'T see 192.168.253.250 though.

    Whats wrong? I spent about an hour yesterday on the phone with
    Motorola and everything looks good on that end. And as far as I know,
    the Cisco looks right. Am I missing something? I'm not at the remote
    (Baltimore) site, but I can VPN in and see the router. Is there
    something physical that could be causing this? (bad cable, etc) Or is
    it a config thing? I've confirmed the DLCI and timeslots. I'm getting
    A LOT of heat to get this fixed and I'm out of ideas!!!

    I'm including the interface config on the 1720 and a sho int0

    Have you tried to change LMI type? post 'debug frame lmi' output...

    Also, you may have FR encapsulation mismatch... Is FR encapsulation equal to
    the both DTE's in your FR network?
    Also, is the link flapping? (up/down line protocol status changing couple of
    times) ? I see a lot of interface errors comparing to the fact that there is
    no "real" application traffic passing trough your serial interface since FR
    isn't working...Also, I noticed that you don't get LMI stat recvd for each
    LMI enq sent... But I don't suspect your line quality since if it is the
    case then you would had partial succes for your ping... Of course, IP config
    is ok for both sides?:)

    Try above changes and let mi know the results...

    I do a "debug frame lmi" and I get this:
    Frame Relay LMI debugging is on
    Displaying all Frame Relay LMI data

    Thats it.
    I rebooted yesterday afternoon and the lmi #'s look like this now:

    Num Status Enq. Sent 7254 Num Status msgs Rcvd 7251
    Num Update Status Rcvd 0 Num Status Timeouts 3

    Here's what I've got for the interfaces:
    interface Serial0
    bandwidth 256
    no ip address
    encapsulation frame-relay IETF
    service-module t1 timeslots 1-4
    frame-relay lmi-type ansi
    !
    interface Serial0.1 point-to-point
    ip address 192.168.253.250 255.255.255.0
    no cdp enable
    frame-relay interface-dlci 16 IETF

    The motorola on the other side of the circuit is 192.168.253.249 and
    can ping itself.

    I'm still not convinced that theres not something wrong with the
    Motorola to Cisco connection. The Motorola is an old Vanguard running
    5.3 software.
    I've got another Vanguard here that if I could get it configured, I'd
    send it out to Baltimore to check, but I can't even get to a console on
    the dang thing, anybody know what emulation Motorola uses?
