| 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 | |
| Service Addresses: | |

| addresses. In a later issue I will publish a complete list. | |
