The ADM responds: AT COMMAND MODE bbbbbbbbbbbbbbb X.25 Call Options If you are using the DX.25 Data Mode, you may need to specify call options when you dial a data call. The call options that can be used for DX.25 data calls are listed below.
bbbbb Using the CMD and AT Commands b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbb Programming Telephone Numbers for Memory Dialing You can program up to nine telephone numbers for memory dialing of data calls and assign them customized names for easy access. Up to 30 digits can be entered. These numbers are labeled m1 through m9. Options associated with a memory dialing number include the telephone number, user selectable name, data profile, and X.
bbbbb Using the CMD and AT Commands b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 3. Type the value for that option (for example, 5552222). The ADM responds by displaying a table of all values for this memory location and prompts again: Type option name (or Q to quit): 4. Type in the next option name for which you want to assign a value and repeat Step 3.
bbbbb Using the CMD and AT Commands b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbb Memory Dialing The ADM dials the number and loads any data profile stored with the telephone number. For example, use the following command to dial a number stored at memory location 1: At the CMD: prompt, type: dial m1 or dial name or just simply name where name is the actual name you have assigned to the memory number.
bbbbb b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb Data Options and Profiles 4 bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb The 8500 series ADM stores data options (configuration information) to tell it how to communicate with the far end. The options, listed in Table 4-1 are explained in this chapter. For most applications, you will find that the CMD Local Mode factory default settings (those settings are in bold print in the table) will work for you.
bbbbb Data Options and Profiles b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbbbbbbbb Table 4-1.

bbbbb Data Options and Profiles b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbb Creating (Programming) a Data Option Profile It is possible for you to program profiles p1, p2, p3, and p4. Profile 1 (p1) is automatically loaded after a set self-test or power-up. The values of p1 should be set to your most frequently used settings. To change the option values of any of the stored profiles use the program command. The program command provides a series of prompts to help you with this task.

Type the name of the next option you want to change and repeat steps 2 and 3. 6. When you are finished changing options, type q to quit. 7. The ADM prompts: Do you want to save the change(s) you must (Y or N)? Type y to save new values. The ADM responds: p1 updated Type n to cancel new values. The ADM responds: No changes to p1 8.
bbbbb Data Options and Profiles b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbb Setting Options: Changing Your Active Profile, pA To change the option values in the active profile (pA), use the set command. The program command cannot be used to change options in pA. To change an option value in pA, at the CMD: prompt type: set option to value For example: set echo to on set text to diagnostic NOTE: Values in pA are not automatically stored.
bbbbb Data Options and Profiles b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb bbbbbbbbbbbbbbb Storing an Active Profile, pA If you want to save the active profile as a stored profile, type: copy pA to p2 The above command stores your active profile in p2. The system responds: p2 updated If you want to store your active profile in p1, repeat the steps above but substitute p1 for p2. Remember, in pA you cannot program your options; the settings in pA, therefore, are not automatically stored.
bbbbb Data Options and Profiles b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb NOTE: In all of the above command procedures, the word ‘‘to’’ is optional. Examples of the command without ‘‘to’’ are: copy p1 pA copy pA p1 copy p0 p1 bbbbbbbbbbbbbbb Viewing an Option Profile To display the option values for any profile, use the view command. Type view to display the values of the active profile. Type view p1 to display the values of stored profile p1.

If your PC does not support eia flow control, you will have to set the flow control options to off and ensure that flow control is not required. That is, both endpoints must operate at the same speed and the speed cannot exceed the effective throughput capability of the data channel.

Factory default speed and parity are set at 9600 bps and space, respectively. Speed and parity settings span all profiles.
bbbbb b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb Testing 5 bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb b bbbbbb You can perform three tests on your 8500 series display set ADM: local loopback test, remote loopback test, and self-test. Taken together, these three tests help you isolate data communications problems.
bbbbb Testing b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb To initiate a local loopback test, do the following: 1. At the CMD: prompt, type test local on your data terminal. The ADM displays: LOCAL LOOPBACK TEST ENTER ATTENTION SEQUENCE TO END TEST 2. Type characters on your terminal keyboard. They will be echoed on your screen. If you find no errors, the ADM passed the test. If you find errors, refer to Chapter 6, ‘‘Troubleshooting.’’ 3.
bbbbb Testing b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb b bbbbbb Remote Loopback Test This test requires compatible AT&T equipment at the remote end. The remote loopback test ensures that no problems with data transmission are occurring in the data transfer circuit. When you initiate a remote loopback test, data is transmitted from the module at the far-end, where it is looped back to your ADM. A data call must be established before you initiate a remote loopback test.

Note, there may be other similar conditions which will cause a lock-up as well.
bbbbb Troubleshooting b bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb If the autoadjust option is off and your data terminal or PC is running at a different speed than the ADM, you will not be able to communicate. If you inadvertently set the local.cr option to the space character, you will not be able to set it back. The Data Reset command allows you to reset all the data options in the active profile to their factory default (p0) values.
