With 500 cps (5 kbps) using V.32 it seems that your modem is suffering
from fallback.  That is, your V.32 modulation is doing 4800 bps and
not 9600 bps due to line conditions.  This has been my constant experience
with V.32 in international calls (Tokyo to San Francisco).

Your best solution is to use TELEBIT PEP modems at each end of your
connection with a window size 3 uucico and the TELEBIT UUCP protocol
support.  You will more likely see 8-10 kbps.  PEP has better performance
over international line and adverse phone line conditions.

For more information, e-mail TELEBIT at modems at telebit.com and ask for
the document: TELEBIT PEP MODEM CONSIDERATIONS FOR ADVERSE COMMUNICATIONS
LINKS.  Good Luck!
