Configuration File Selection
Use the following steps to select a configuration file:
1. Is your modem an IBM 7852-400?
If Yes, use modem configuration file modem_m0.cfg and go to step 7 on
page 179.
Note: The IBM 7852-400 modem has DIP switches on the right side of the unit.
See “IBM 7852-400 DIP Switch Settings” on page 181 for the correct
switch settings.
If No, continue with step 2.
2. Is your modem an IBM 7857-017?
If Yes, use modem configuration file modem_m1.cfg and go to step 7 on
page 179.
Note: The IBM 7857-017 modem has two telephone line connections on the
back of the unit. One is marked LL (for Leased Line), and the other is
marked PTSN (for Public Telephone Switched Network). The service
processor expects to use the modem on the public network, so the
telephone line should attach to the PTSN connector.
If No, continue with step 3.
3. Does your modem respond to the extended command set (prefixed with &)?
If Yes, go to step 5 on page 179.
If No, continue with step 4.
4. Does your modem respond to:
ATZ reset command
or
ATZ
n
reset commands, where
n
can be 0, 1, and so on?
If ATZ, configuration file modem_z.cfg is recommended.
If ATZ
n
, configuration file modem_z0.cfg is recommended.
Go to step 7 on page 179.
