Cingular CSD roaming off GSM?

Archived from groups: alt.cellular.cingular (More info?)

A Cingular CS rep told me that CSD roaming OFF Cingular/partner GSM is
not allowed; i.e. no CSD on Cingular/partner TDMA or analog.

Is there any evidence against this?

    I've communicated with a guy who says he's able to do CSD on Cingular
    TDMA and AMPS using an older tri-mode Nokia phone and an Ositech King
    of Clubs card.

    This, combined with Cingular's GSM/GPRS is probably the best cellular
    coverage available don't you think?

    Just AMPS, not TDMA.

    Thanks John. He really wasn't sure which he was using because the KoC
    autoswitches. Is CSD blocked on Cingular TDMA?

    No, CSD works fine on home area Cingular TDMA, both pure TDMA and GAIT,
    but I've never seen it work while roaming on a non-Cingular carrier.

    Not familar with the KOC card but if it's like other cellular-ready
    pccards it probably doesn't use CSD at all. They contain(ed) a real
    analog modem and auto-switched the phone into AMPS when the data call
    connected--either to a private modem or to a modem pool at the carrier.
    I used several of those over the years. I believe CSD, circuit switched
    data, is purely a digital thing.

    Well, after looking at the Ositech site I'm not sure what it does.
    Appears to have hardware to support both--analog modem when on AMPS and
    CSD adapter/interface when on digital. Interesting.

    The Ositech King of Clubs is based on the Trumpcard cellular modem, which
    works only over AMSP. For digital (TDMA, GSM, whatever), there is no actual
    modem per se, and thus Ositech isn't needed at all, claims for its silly
    CellFlex(tm) technology notwithstanding.

    Putting all of the above together it appears that Cingular blocks CSD
    outside the home area, but does not block using AMPS for data.

    This is consistent with the above info and with the fact that Cingular
    offers no phone that can be forced into AMPS mode (I've been told by
    the Ositech people - presumably to discourage the use of AMPS.)

    It also means that one can get very broad data coverage on Cingular by
    buying an old phone that can be forced into analog on ebay for use on
    AMPS when desired. Magicbus reports 14.4 kbps with an Ositech King of
    Clubs on AMPS which is a lot better than no data coverage at all.

    You may port connect at 14.4 Kbps, but I doubt that you're actually getting
    that kind of throughput, probably more in the range of 4.8 - 9.6+ Kbps.

    I use an old bagphone for AMPS and get less than 2400 baud. 9.6 sounds
    dreamy! Certainly MUC better than zero!

    It appears that Cingular's GAIT nationwide plans include AMPS minutes
    in unlimited nights and weekends. If so, cingular would be the most
    cost effective carrier for really broad data coverage.

    In my opinion "effective data coverage" requires long connect times
    but little actual traffic. Trying to work off-line has never been
    successful for me; I like to read a message then respond in real time
    (most of the time is spent thinking and typing slowly!)

    That's what GPRS is good for, since you're not charged for connect, only
    actual data traffic.
