Foreign Addresses
If you intend to configure an FSC gateway as part of your HP Desk
network, you will also need to think about how your users are going to
address messages traveling through the gateway. There are two different
methods, each of which is best suited for a particular situation.
Explicit Foreign Addressing
This method allows your users to send messages through the FSC gateway to
anyone, whether that person is configured on HP Desk or not.
The foreign address can be up to 512 characters long and can be split up
over up to 8 lines. It is specified in brackets on a new line after the
gateway location. For example, if someone in the Pharaoh Company wanted
to send a telex to someone in their advertising agency, they would
specify the name of the person, the mailnode for the FSC gateway
configured for HP Telex and the foreign address:
David McKinney /USCORP/TE &
(007 23 101275 : ADFIRM G)
In this case, the foreign address is the telex number and answerback
code.
Although this method allows your users to send messages to people who are
not configured on HP Desk, to use it they have to type in the foreign
address. This is not particularly friendly and can be a source of
mistakes.
The need for the user to type out the foreign address each time he or she
wants to send a message can be eliminated by configuring the foreign
address at the same time you configure the HP Desk name and mailnode.
Foreign Address Aliasing
This method allows your users to send messages to and receive messages
from users on non-HP Desk systems as if they were HP Desk users.
At the gateway computer, you configure the user on the foreign system as
an HP Desk user. You then configure that user's foreign address and
associate it with the HP Desk address. Take the example of Kathleen
Reynolds, who is a user on the accounts department's IBM machine at US
Corporate Headquarters. She would be configured on the NEWYORK gateway
as:
KATH REYNOLDS /USCORP/TE associated with KRADB.SOLO
where KRADB.SOLO is her IBM log on identifier.
If a message is sent by an HP Desk user to Kath Reynolds, all the HP Desk
user need include in the distribution list is:
To: Kath REYNOLDS/USCORP/TE
HP Desk knows it must send this message to user KRADB.SOLO on the US
Corporate Headquarters IBM machine known as USCORP/TE.
When this address is displayed in HP Desk, no foreign address is shown
and no indication given that a foreign address is associated with the
name. The address information passed out of HP Desk in the ARPA message
file looks like this:
TO: "Kath REYNOLDS" @ [KRADB.SOLO]
Suppose that Kath Reynolds wants to send a message from the US Corporate
Headquarters IBM machine to an HP Desk user called Riki Cook. Kath
addresses the message to RSTYS.HP23. An ARPA message file will arrive at
the NEWYORK gateway on the HP Desk machine containing an entry such as:
To: "RC" @ [RSTYS.HP23]
As Riki's IBM identifier has been associated with an HP Desk address, the
address will be converted to an HP Desk address of:
To: Riki COOK/MANF1/PH
Any user and addressing information which was previously in the ARPA file
is overwritten by the HP Desk name and address.
* Your HP Desk users don't need to know about the foreign addresses
of the recipients of their messages.
* Users who receive messages from someone on a foreign system can
use the HP Desk REPLY command to respond to them.
* If you are part of a local network, the foreign address only has
to be configured on the gateway computer.
* You can configure a number of associated foreign addresses for one
user. This allows your users to receive and reply to messages
from a number of foreign systems.
* You can also use HP Desk as a routing system and enable users on,
say an IBM PROFS system, to send messages to and receive from
users on, say an IBM DISOSS system.
The disadvantage of foreign address aliasing is that initially
configuring the dummy HP Desk users and their associated foreign
addresses could be a large task, depending on how many users are
involved.
For this reason it is best to restrict the use of foreign address aliases
to those people to whom your HP Desk users send messages to and receive
messages from on a regular basis.
If you decide to use foreign address aliasing, your users can still
include explicitly declared foreign addresses in their distribution
lists. If they do the message is passed out to the foreign system,
regardless of whether any aliases are configured on the gateway machine.
