Step 12. ____ Connect the 25-pin V.24 cable from the DTE to the 25-pin

connector on the modem rear panel. Fasten the connector retaining

screws.

Step 13. ____ Set the modem power switch to ON. Wait until the modem

operational message is displayed on the operator panel (about 15

seconds).

If the modem is connected to an asynchronous DTE which can send AT

commands to the modem, you can use the DTE to configure the modem

to match your communication system requirements. Otherwise, the

modem can be configured through the operator panel, refer to “Setting

the 7858 Connected to the COM1 Connector (ASYN)”

Note: Ten factory Redefined modem configurations are available. You

could retrieve the factory configuration which better matches your system

requirements, make any further configuration adjustment you should

require, and save your modem configuration in one of the ten user

configuration slots.

Step 14. ____ Now the modem is ready for operation. You can try it with your

system. If you observe a basic system problem, such as the DTE not

being able to send commands to the modem successfully, verify again

that your individual modem configuration parameters are matching your

system requirements.

If you have a problem because the dialing tone is not provided by

your PBX or exchange set the modem as follow:

¹Power OFF the modem

¹Power ON the modem while you are pushing the Enter key at the

same time. Release the Enter key when the message: DATAPUMP

TEST is displayed.

After this, the modem performs the dial through the switchboard without

looking for dial tone (Blind dial ATX1). Thios setting is maintained even if

the modem is powered OFF and ON again.

Step 15. ____If you have a problem while using the modem, see "Problem

Determination" chapter in the

IBM 7858 Professional Modem Guide to

Operation

, GA13-1981.

Setting the 7858 Connected to the COM1 Connector (ASYN)

1. ____ Power OFF the modem

2. ____ Press and hold the ↑ key while power ON the modem.

3. ____ The modem is set to Factory 0 in AT command mode.

Saving the Configuration of the 7858

If you want to save the configuration just defined, in order to have it loaded again at

the next modem reset, perform the following steps:

1. ____ Press the ↓ key until the "CONFIGURATIONS" message

displayed the top row.

2. ____ Press the → key until the "Store User Conf."

message displayed the bottom row.

3. ____ Press the ENTER key select the option.

Chapter 1. Installing and Setting Up Your Service Processor 1-25

4. ____ Pressing the ↑ key, select the User Configuration Location where the

current modem configuration must be saved (0 to 9).

5. ____ Press the ENTER key save the current modem configuration.

6. ____ The defined configuration now active and saved.

Now every time the modem is reset (power on), the last user configuration which

was saved is loaded as the current modem configuration.

Connecting the 7858

1. ____ Plug the cable (PN 782984) into slot 3 .1/ of the Service Processor. The

drawer and slide kit (PN 58G5698) are always shipped, but are not used if the

expansion frame is not installed.

2. ____ On the modem's rear panel, plug the other cable lead into the 25-pin

connector .2/.
