Getting started, and understanding how the analog modem in the CDS-9022A CDMA and Analog Modem works. This User Guide is an addendum to the CDS-9020 User Guide, and assumes the reader has a basic understanding of Data Communications Equipment (DCE) and Data Terminal Equipment (DTE) products. The Basics The standard landline modem is analog to analog via your local telephone company. When switching from a non-CDMA network to an Analog-only network, the call will be dropped if you are moving.
only powers the Analog modem up for 20 seconds after the last keystroke. When programming or making changes to the program, make sure you store the new profile (AT&W). Host AT-Commands and setting up the host PC Modem For the host modem side connecting to a fixed CDS-9022A in analog mode, we suggest leaving the Default String for the cleanest connections, but cellular sites differ. In most Metropolitan Service Areas (MSA) they may have newer equipment at their cell site.
Suggested AT-STRING for the host modem calling a CDS-9022A Modem for a V.32 connection AT&F;+MS=V32,1,4800,9600,4800,9600;-SEC=1,12;)M1;\N5;&W This is a CONEXANT chipset command. It is the fastest way to connect to the CDS9022 fixed or mobile units that have files bigger than 50K plus. Note: In the past few years since Rockwell merged with CONEXANT, the ATSTRING commands conform to the above.
Default AT-STRING for CDS-9022A Modem setup Note: This command string is for V.32 4800bps to 9600bps AT&F;+MS=V32,1,4800,9600,4800,9600;- SEC=1,12;)M1;\N2;S7=58;X0;S24= 40;S30=150&W The above String will prefer a MNP10EC connect, but will also accept an LAPM V42bis. For optimum communications performance with your Analog landline to the CDS9022 in Analog Mode, you should be using a CONEXANT/ROCKWELL HOST modem chipset, or other cellular ready modem.
D6 = ON Analog Mode - CDS-9022A is in analog mode. (*) Command is only used for testing Outbound calls from the CDS-9022A Refer to CDS-902X User Guide Configuration Menu section regarding DTE speed for clarification. MNP 10EC Command Set Note: These extended commands are for CDS-9022A setup only. Refer to the section concerning programming the analog modem profile in the CDS-902X User Guide. AT)Mn Automatic Level Adjustment Controls This command is included only for compatibility and performs no function.
AT-SEC=n Enable/Disable MNP10-EC Enables or disables MNP10-EC operation. The command format is: AT-SEC=n, [] where is the optional transmit level sub parameter. AT-SEC=0 Disable MNP10-EC; the transmit level is that defined in S91. AT-SEC=1, [] Enable MNP10-EC; the transmit level will be defined by the sub parameter range 0 to 30 (0 dBm to -30 dBm), the default ( not specified) is the S91 value.
ATQn Quiet Results Codes Control This command enables or disables the sending of result codes to the DTE according to the parameter supplied. The parameter value, if valid, is written to S14 bit 2. ATQ0 Enables result codes to the DTE (Default.) ATQ1 Disables result codes to the DTE.
This should not be necessary in most cases, but, there are some 2400bps, 1200bps, or even 9600bps modems you may not be able to connect to without using the following method: Using the +MS= command. AT+MS=V32,1,4800,9600,4800,9600 will set the modem to use V.32 modulation, auto mode detection, with 9,600bps as the lowest transmit connection rate acceptable and the highest transmit connection rate attempted. See “Setting up DTE bps” in the CDS9020 User Manual.

Voice Mode for the CDS-9022A and CDS-9052 Cellular Modems Using voice mode requires DataRemote headset model DRH-HDST for proper operation. To initiate voice mode from data mode, enter: AT OK (response from modem) AT+CDV You will hear a faint beep over the headset after a few seconds and then ringing. When called party answers go ahead and talk.
