We have been providing
in-house dial-up facility for members of the University for
several years. Though we always employ the most advanced technologies
at the time of installation, as time goes by, the advancement
of new telecommunication technologies is so rapid that it becomes
impractical to keep on upgrading our existing modem pools to
catch up with the contemporary standards. This results in a
degradation of performance. On the other hand, the emphasis
on using IT for teaching has stimulated a large crowd of users
who need fast Internet access frequently and the demand for
dial-up facility to support Web-based instructions keeps increasing.
As such, there is an urgent need to replace our present dial-up
equipment. However, sooner or later we will encounter another
cycle of obsolescence. Therefore, the only way out is outsourcing.
Outsourcing has distinct
advantages over in-house development. These include greater
flexibility in expanding or downsizing the modem pools, saving
maintenance cost of equipment, avoiding technological obsolescence,
reducing support effort, economy of scale, and more. Recently,
the University has awarded the dial-up facility contract to
the Cable & Wireless Hong Kong Telecom (CWHKT) after painstaking
testing and evaluation of its Virtual Private Dial-up Service
(VPDS). The dial-up facility thus provided is through the ATM
technology, making the addition of ports and bandwidth flexible
and inexpensive.
Among the new dial-up
facility that constitutes over 800 dial-up lines, 100 lines
are dedicated for staff, 600 lines are for both staff and students,
and over 100 lines have 30 minutes connection limit during peak
hours. These modems are provided through a dedicated Cisco Remote
Access Server of carrier grade, supporting most popular standard
protocols such as V.34, V.90 and K56Flex. They also support
a variety of modems. A detailed list of supported modems can
be found under the CSC Web page. On the CityU Intranet home
page, simply click Admin./Support Centres followed
by Computing Services Centre. On the CSC home page,
click Services. Thereafter choose CityLink
Plus remote access facility followed by For
All Staff. On the right panel, click the link List
of Modems supported. Alternatively, you may access the
URL directly at http://www.cityu.edu.hk/csc/dialup/usrguide/modem.htm.
As the whole dial-up
facility has been reorganised, all previous dial-up phone numbers
become obsolete. The new phone numbers for corresponding modem
pools are depicted on page 26 under Key Services and Information.
You may need to reconfigure
your PC to cope with these new phone numbers. If your modem
cannot connect properly to the modem pools, check the above-mentioned
modem list to find out whether your modem is supported. If not,
you may need to replace your modem or upgrade the modem software
in order to get full advantage of these high-speed modem pools.
