|
continued. Try again later.
|
|
|
|
(b) CALL CLEARED -- Either the foreign network requested is not
|
|

Gateway Identification
|
|
----------------------
|
|
|
|
The network generated messages sent to Datapac ITI terminals include
|
|
a 3-digit field to identify the gateway involved. This field is
|
|
shown as (XXY) for the network messages listed in above.
|
|
|
|
If the call has not been established, the XXY = 000. If the call has
|
|
been established, then
|
|
|
|
XX = 2-digit Datapac Service Exchange (DSE) of the gateway node used
|
|
for the call
|
|
|
|
Y = Gateway ID of the gateway used for the call.
