|
| 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. |
|
|
| NA Not authorized for this service. |
|
|
| NC Circuits busy, try again. |
|
|
| 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. |
|
|
| Canada Toronto 416-947-2992 (1200 Baud V.22 Modem Standard) |
| U.S.A. Los Angeles 213-629-4025 (300/1200 Baud U.S.A. Modem Standard) |
| Jersey City 201-798-8500 |
| New York City 212-269-1274 |
| 212-809-1164 |
