Placing A Call From An Async Terminal - Cabletron Systems SmartSwitch 6000 User Manual

Placing a Call from an Async Terminal

Async Terminal Operations
One way to place a call is simply to enter the calling address (subscriber ID) of the
destination DTE. (There must be a record for that subscriber ID.) User data and/or
facilities (in any combination) can be included, as described below.
To place a call using facilities and user data, enter the data in the format:
f,f,f-addressDdata or f, f, f-addressPdata
is the letter(s) representing the desired facility(s):
f
Gnn = CUG (nn is the CUG number)
= Group Send
Z
= Priority
Y
R = Reverse Charging
= NUI
N
– is the called address,
address
or – is the letter "D" or "P" (if P, the data will not be echoed locally),
D P
– is the user data.

An Abbreviated Address can be substituted for the complete called address
if no facilities are included. Also, X.28 convention demands that when
sending a Call Request packet using an abbreviated address, you precede
the address with a period. If you want to add user data to the packet, you
must separate it from the abbreviated address with an asterisk. The format
is:
.address*data
If the Call Request is successful, the async PAD will receive a Call Accept packet
from the device at the other end of the call. Connection is now established, and the
terminal will display COM. If the Call Request fails, the terminal will display a diag-
nostic message explaining why. The various messages are some of the PAD service
signals described later in this appendix.
