Network Procedure Differences
|
|
|
|
The Global Telecommunications Network (GTN) is Citibanks's international data
|
|
network, which allows Citicorp customers and personnel to access Citibank's
|
|
worldwide computerized services.
|
|
|
|
Two different sign on procedures exist: Type A and Type B. All users, except
|
|
some in the U.S., must use Type B. (U.S. users: the number you dial into
|
|
and the Welcome Banner you receive determine what sign-on procedure to
|
|
follow.) Welcome banners are as follows:
|
|
|
|
TYPE A:
|
|
WELCOME TO CITIBANK. PLEASE SIGN ON.
|
|
XXXXXXXX
|
|
|
|
@
|
|
PASSWORD =
|
|
|
|
@
|
|
|
|
TYPE B:
|
|
PLEASE ENTER YOUR ID:-1->
|
|
PLEASE ENTER YOUR PASSWORD:-2->
|
|
|
|
CITICORP (CITY NAME). KEY GHELP FOR HELP.
|
|
XXX.XXX
|
|
PLEASE SELECT SERVICE REQUIRED.-3->
|
|
|
|
|
|
Type A User Commands
|
|
|
|
User commands are either instructions or information you send to the network
|
|
for it to follow. The commands available are listed below.
|
|
|
|
User Action: Purpose:
|
|
|
|
@ (CR) To put you in command mode (mode in which you can put
|
|
your currently active service on hold and ask the network
|
|
for information, or log-off the service). (NOTE: This
|
|
symbol also serves as the network prompt; see Type A
|
|
messages.)
|
|
|
|
BYE (CR) To leave service from command mode.
|
|
|
|
Continue (CR) To return to application from command mode (off hold)
|
|
|
|
D (CR) To leave service from command mode.
|
|
|
|
ID To be recognized as a user by the network (beginning of
|
|
sign on procedure), type ID, then a space and your
|
|
assigned network ID. (Usually 5 or 6 characters long)
|
|
|
|
Status (CR) To see a listing of network address (only from @
|
|
prompt). You need this address when "reporting a
|
|
problem."
|
|
|
|
Type A messages
|
|
|
|
The network displays a variety of messages on your screen which either require
|
|
a user command or provide you with information.
|
|
|
|
Screen shows: Explanation:
|
|
|
|
@ Network prompt -- request for Network ID.
|
|
|
|
BAD PASSWORD Network does not except your password.
|
|
|
|
<address> BUSY The address is busy, try back later.
|
|
|
|
|
|
WELCOME TO CITIBANK. Network welcome banner. Second line provides address
|
|
PLEASE SIGN ON. # to be used when reporting "problems."
|
|
XXX.XXX
|
|
|
|
<address> ILLEGAL You typed in an address that doesn't exist.
|
|
|
|
<address> CONNECTED Your connection has been established.
|
|
|
|
DISCONNECTED Your connect has been disconnected.
|
|
|
|
NOT CONNECTED You're not connected to any service at the time.
|
|
|
|
NUI REQUIRED Enter your network user ID.
|
|
|
|
PASSWORD = Request for your assigned password.
|
|
|
|
STILL CONNECTED You are still connected to the service you were using.
|
|
|
|
? Network doesn't understand your entry.
|
|
|
|
|
|
Type B User Commands and Messages
|
|
|
|
Since the Type B procedure is used with GTN dial-ups, it requires fewer
|
|
commands to control the network. There is only 1 Type B command. Break plus
|
|
(CR) allows you to retain connection to one service, and connect with another.
|
|
|
|
|
|
Screen Shows: Explanation:
|
|
|
|
CITICORP (CITY NAME). Network Welcome banner. Type in service address.
|
|
PLEASE SELECT SERVICE
|
|
|
|
COM Connection made.
|
|
|
|
DER The port is closed out of order, or no open routes are
|
|
available.
|
|
|
|
DISCONNECTED You have disconnected from the service and the network.
|
|
|
|
ERR Error in service selected.
|
|
|
|
INV Error in system.
|
|
|
|
MOM Wait, the connection is being made.
|
|
|

|
|
|
|

|
|
|
|
NP Check service address.
|
|
|
|
OCC Service busy, try again.
|
|
|
|
|
|
Sign-on Procedures:
|
|
|
|
There are two types of sign on procedures. Type A and Type B.
|
|
|
|
|
|
Type A:
|
|
|
|
To log onto a system with type A logon procedure, the easiest way is through
|
|
Telenet. Dial your local Telenet port. When you receive the "@" prompt, type
|
|
in the Type-A service address (found later in the article) then follow the
|
|
instructions from there on.
|
|
|
|
Type-B:
|
|
Dial the your GTN telephone #, then hit return twice. You will then see:
|
|
|
|
"PLEASE ENTER YOUR ID:-1->"
|
|
|
|
Type in a network ID number and hit return.
|
|
|
|
You will then see
|
|
|
|
"PLEASE ENTER YOUR PASSWORD:-2->"
|
|
|
|
Type in Network Password and hit return.
|
|
|
|
Finally you will see the "CITICORP (city name)" welcome banner, and it
|
|
will ask you to select the service you wish to log onto. Type the address and
|
|
hit return. (A list of addresses will be provided later)
|
|
|
|
Trouble Shooting:
|
|
|
|
If you should run into any problems, the Citicorp personnel will gladly
|
|
help their "employees" with any questions. Just pretend you work for Citibank
|
|
and they will give you a lot. This has been tried and tested. Many times,
|
|
when you attempt to log on to a system and you make a mistake with the
|
|
password, the system will give you a number to call for help. Call it and
|
|
tell them that you forgot your pass or something. It usually works, since
|
|
they don't expect people to be lying to them. If you have any questions about
|
|
the network itself, call 305-975-5223. It is the Technical Operations Center
|
|
(TOC) in Pompano, Florida.
|
|
|
|
Dial-Ups:
|
|
|
|
The following list of dial-ups is for North America. I have a list of
|
|
others, but I don't think that they would be required by anyone. Remember:
|
|
Dial-ups require Type-B log-on procedure. Type-A is available on systems
|
|
accessible through Telenet.
