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:
¹
Power OFF the modem
¹
Power 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). This 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.
