ISPs Supporting ISDN Connectivity
A principal goal of most ISDN installations is internet access. Not all Bangkok ISPs
support ISDN connectivity, and those that do require opening a separate account for
ISDN access (unlike practice in other countries whose ISPs offer both analogue and
digital access via the same account profile).
ISDN accounts currently run about 20-35 baht per hour for a single 64 kpbs channel,
and twice this if access is via Multilink PPP. But for applications where time is money,
the increment over the analog access price is cost-effective.
A survey of local ISPs shows that they differ substantially in their marketing emphasis,
types of service, and user-friendliness. Loxinfo and A-Net provided the best setup
packages while at least three of the ISDN-enabled ISPs have their SMTP servers interna-
tionally blacklisted for harbouring spammers. (Researching this article showed why: a
few days after KSC kindly agreed to set up a test account, spam started coming from CS
Internet.)
Also, a warning: if you already have an e-mail account, and successfully set up an ISDN
e-mail account, you will discover that you cannot send out mail! You must obtain from
your ISDN-enabled ISP the domain name or IP address of its SMTP server and input it
to the SMTP Server configuration menu of your mail client. You may have to change
this on the fly if you access different ISPs or ISP accounts from the same mail client. Or
if your mail client allows, configure separate profiles or accounts for the two or more
SMTP gateways you access.
The accompanying table lists Bangkok-based ISPs currently promoting ISDN access.
Each intending user should evaluate ISPs according to his own requirements. Import-
ant differences are hourly cost of access, availability of 24/7 technical support and
knowledgeability of support personnel, reliability of access and of international links,
and support of a news server.
Since ISP performance by each criterion may vary from time to time and with manage-
ment changes, intending users may have to experiment to find their dream ISDN-
enabled ISP.
