There are currently two 56Kbps modem standards: x2 and K56Flex. Users of K56Flex modems or other modems dialing to the HKUPPP 56K Server can only achieve up to the data rate of 33.6Kbps or less. To enjoy higher than 33.6Kbps connections, you need to use a x2/56Kbps modem.
Apart from the speed improvement, the new HKUPPP 56K Servers use leased channelized-T1 circuits, each of which supports 24 56Kbps PPP dial-up connections. This provides more stable connections and there will be fewer chances of line dropping due to cross-talk and noise problems which are experienced with the individual analogue dial-up lines. Therefore, we would encourage all our users to choose to use these new lines if possible since they can benefit from the new modem pool to have better quality connections even when non-x2 modems are used.
A new HKUPPP dial-up package, tailored for use with the the x2/56K HKUPPP modem pool, is being developed and will be available very soon. For the time being, you can follow the instructions provided on the web URL: http://www.its.hku.hk/services/ppp56k.htm to configure manually the existing HKUPPP package installed on your PC for dial-up connection to the new modems.
