This solution is only recommended to companies who already uses their AS/400
as Internet server
Example E)
Works as seen in example A. But with that
difference that the AS/400 communicates with
a local mail server, that handles all the
outgoing communication.
See the following page for explanation of
special terms.
ISDN
(Integrated Services Digital Network) An international telecommunications
standard for transmitting voice, video and data over digital lines running at 64
Kbps. The telephone companies commonly use a 64 Kbps channel for digitized,
two-way voice conversations.
ADSL
Short for Asymmetric Digital Subscriber Line, a new technology that allows more
data to be sent over existing copper telephone lines (POTS). ADSL supports data
rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate)
and from 16 to 640 Kbps when sending data (known as the upstream rate).
ADSL requires a special ADSL modem.
Mail server
A computer in a network, that provides "post office" facilities. It stores incoming
mail for distribution to users and forwards outgoing mail through the appropriate
channel. The term may refer to just the software that performs this service, which
can reside on a machine with other services.
DNS
(Domain Name System) Name resolution software that lets users locate
computers on a UNIX network or the Internet (TCP/IP network) by domain name.
The DNS server maintains a database of domain names (host names) and their
corresponding IP addresses. In this hypothetical example, if
www.mycompany.com were presented to a DNS server, the IP address
204.0.8.51 would be returned. DNS has replaced the manual task of updating
HOSTS files in an inhouse UNIX network, and of course, it would be impossible
to do this manually on the global Internet, given its size.
POP3
(Post Office Protocol 3) A standard mail server commonly used on the Internet. It
provides a message store that holds incoming e-mail until users log on and
download it. POP3 is a simple system with little selectivity. All pending messages
and attachments are downloaded at the same time. POP3 uses the SMTP
messaging protocol.
