Dial Command
This setting is an ASCII string for the modem string used to initiate a dial sequence with the modem.
If this parameter is left empty, the default “ATD” sequence is used by the BMC.
Ring Duration
The Modem Ring Time setting species the time it takes the BMC to claim the serial connection
after detecting the phone ringing while monitoring the Ring Indicator (RI) line. By conguring the
Ring Duration, a user can specify the amount of time that the BMC takes to switch the mux when
RI is rst detected.
The ring duration value should be entered in 500 ms increments; if not, SMU rounds this value down
to the nearest 500. Also, a “0” value congures the BMC to switch the mux immediately on the rst
detected transition of RI. The values entered can be in the range from 0-31509, but the values the
SMU retains are from 0-31500 rounded down to the nearest 500.
Ring Dead Time
The second conguration setting that deals with Modem Ring Time is Ring Dead Time. This setting
allows a user to specify the amount of time that the RI signal must be deasserted before the BMC
determines that ringing has stopped.
The ring dead time value should be entered in 500 ms increments; if not, SMU rounds this value
down to the nearest 500. The value entered can be in the range 0-7999, but the values that the SMU
retains are from 0-7500 rounded down to the nearest 500.
The value entered should also reect any dependencies on modem type, location of server, and the
phone line carrier.
Destination Dial Strings View
The menu shown in Figure 50 displays the current setting of each destination dial string available on
the target platform. Since the number of dial strings available is platform-dependent, the number
available on the target platform is shown above the list of dial strings. For the MAXDATA PLATINUM
9000-4R Server, the number of destination dial strings is 6. The length of a destination dial string is
platform-dependent; for the MAXDATA PLATINUM 9000-4R Server, the number of bytes that can be
entered by a user is 31, and a termination character is added onto that.
A dial string can be modied or cleared by selecting the corresponding radio button and then clicking
on the Edit button.

When the BMC sends a dial string to a modem, it automatically precedes it with the currently dened
Modem Init String sequence.
