Communications Software Installation; Modem Power-Up - Paradyne Comsphere 3830 User Manual

COMSPHERE 3800 Series Modems – Model 3830
To ensure compliance with FCC Part 15 Regulations, a ferrite choke
must be installed on the power transformer cable.
1. Open the ferrite choke, place it around the power transformer cable
as close as possible to the connector attached to the modem, and
snap the ferrite choke shut.
2. Install a cable tie behind the ferrite choke to prevent it from sliding
along the cable.

Communications Software Installation

A personal computer commands and controls a dial modem through
communications software. This software, which is installed on the PC,
uses the AT command set to send instructions to the modem. A dumb
asynchronous terminal, however, does not require this software since it
can directly send AT commands.
The Model 3830 can be used with any major communications software.
Refer to your software's user's guide for installation procedures. For an
overview of how to use AT commands and a list of AT commands
supported by the Model 3830, refer to Chapter 4, AT Command Set and
S-Registers.

Modem Power-Up

Once your modem is properly connected to the DTE, dial or leased
lines, and ac outlet, press the modem's rear panel power switch to the
ON position. The modem begins a power-up self-test in which all front
panel LEDs momentarily light (note that this also occurs on a reset of
the modem), and the Power LED remains ON. The state of other LEDs
depends on your modem's configuration.
On initial power-up, the modem is in Command mode. To verify that
the modem is connected and functioning properly, enter the following:

PRESS:
The screen displays OK.
If the modem does not return OK, refer to Appendix A,
Troubleshooting.
