COMSPHERE 3900 Series Modems
Misc
The Miscellaneous configuration options determine specifics for various functions, including
network management parameters and remote modem access.
Table 5-8 shows each Misc (Miscellaneous) configuration option as it appears on the LCD, with
the Sync Leased factory default setting (the default value if the modem is just being installed)
shown following the colon ( : ) on the first line and with all available selections listed on the
second line. Following this is a description of the configuration option. Factory default settings are
listed in Appendix F.
StrapsWhenDisc: No_Change
Nxt No_Change Reload
Straps When Disconnected. Determines whether or not configuration options in the Active (Saved)
configuration area are reloaded to Active (Operating) when a disconnect occurs. This is useful in modem
pooling applications.
H No Change
Configuration options do not change if a disconnect occurs.
H Reload
The Active (Operating) configuration area, which controls modem operation, is reloaded from the
Active (Saved) configuration area when a disconnect occurs. This is useful in modem pooling
applications where it is desirable to start the modem from a known condition after every call. This
allows multiple users to issue AT commands to change the modem's operation for their particular
call.
NOTE: If Reload is selected, the following AT commands are disabled although the OK result code appears
when the following commands are issued: AT&F0, AT&F1, AT&F2, AT&F3, AT&F4, AT&F5, AT&F6,
AT&F7, AT&F8, AT&W0, AT&W1, AT&W2, and AT&Zn=x.
The AT command for the Straps When Disconnected configuration option is S-Register S88=n, where n is 0
or 231 for No_Change, and 1 or 232 for Reload.
Speaker Control: OnUntilCarr
Nxt OnUntilCarr Off On
Speaker Control. Determines if the speaker is OFF, ON until carrier signal is received by the modem, or ON
all the time.
NOTE: Speaker Control can also be temporarily set using the Control branch; however, a reset or power
cycle will restore the modem to the Speaker Control and Speaker Volume configuration option
settings.
The AT command for Off is M0
The AT command for On Until CD is M1.
The AT command for On is M2.
