Authentication |
| credentials to be reset. Trying to register a |
(credentials) |
| modem after doing this will cause a |
problem (cont.) |
| credentials error because the reset values in |
|
| the modem do not match the values the |
|
| MDIS has for that IP Address from prior |
|
| usage. |
|
| This problem is not likely when you are |
|
| initially registering a new modem, unless |
|
| the IP Address was previously used in your |
|
| organization. If a credentials problem is |
|
| indicated, contact the carrier to have the |
|
| credentials for the IP Address reset. |
|
| If you suspect that this occurred, use the |

|
| mode) to view the actual credentials. If the |
|
| displayed credentials are zero, call the |
|
| carrier to get the IP Address reset. |

Flow control | Not | This condition is only possible if you are |
problem | applicable | using manual registration (AT\R1) instead |
|
| of automatic registration. If, after you key |
|
| AT\R1 and press ENTER, the cursor returns |
|
| to the A of the AT and the modem does not |
|
| return an OK or an ERROR within the |
|
| |
|
| have this problem. |
|
| Flow control is only applied when the |
|
| modem is in online mode or is interacting |
|
| with the network in command mode (as it |
|
| is when trying to register). Even if the flow |
|
| control is set improperly, or has a cable |
|
| problem that impacts flow control, you will |
|
| not notice it until you try to register. The |
|
| flow control setting defaults to hardware |
|
| flow control, indicated by \Q2 in the |
|
| modem profile, and this should match the |
|
| COM port setting on your PC’s terminal |
|
| emulator program. If the settings match try |
|
| changing them both to no flow control |
|
| (\Q0) on the DART. If registration now |
|
| works then a broken or missing pin, faulty |
|
| connection, or broken or missing RTS or |
|
| CTS wire is the likely source of the |
|
| problem. |
