Configuring Async Ports
12-17
Port
identify the port(s) that make up the routing path(s).
Redirection Address 0,1,etc.
are up to five subscribers that will be called according to the specified redirection
option. The FRM can redirect an X.25 call to an alternate subscriber if the original
subscriber cannot be reached. (See "
Redirect on Busy
" and "
Redirect on Out of Order
.")
The FRM will call each address in the list until one is reached. If
Systematic Redi-
rection
is enabled, the FRM will not call the original called subscriber, but will start
immediately with the first subscriber in the redirection list.
Configuring Abbreviated Addresses
The Abbreviated Address operation allows you to assign a short name or mnemonic
to be used in place of the subscriber ID when making X.25 calls from a terminal con-
nected to an FRM async PAD port.
To display a list of existing abbreviated addresses and their associated subscriber IDs,
press
[C]
at the Connections and Routing Paths Configuration Menu (or
[A], [D], [C]
from the Main Menu).
To add or change an abbreviated address, press
[D]
at the Connections and Routing
Paths Configuration Menu. When prompted, enter the address you want to use (up to
10 alphanumeric characters).
The address will be displayed; if it is an existing address, the associated subscriber ID
will also be displayed, along with the message
Subscriber ID defined
(or
Subscriber ID
undefined
if the ID is not in the database).
Configuring Async PVCs
An FRM PVC is a "permanent" connection between two physical/logical ports in a
node. This allows communication between the attached devices as soon as they are
powered up, without having to first make a call to establish a connection. Async PVC
support in the FRM includes async-to-async and async-to-X.25.
To display a list of current PVCs, press
[A]
at the PVC Configuration Menu (or
[A],
[D], [E], [A]
from the Main Menu). To add or change a PVC, press
[B]
at the PVC Con-
figuration Menu and enter a 1–4 digit
Connection ID
, which is simply a number unique
to this connection, that identifies the PVC.
