Table 23: J-series Default Modem Initialization Commands (continued)
DescriptionModem Command

When the Services Router applies the modem AT commands in the init-command-string
command or the default sequence of initialization commands to the modem, it
compares them to the initialization commands already configured on the modem
and makes the following changes:
■ If the commands are the same, the router overrides existing modem values that
do not match. For example, if the initialization commands on the modem include
S0=0 and the router’s init-command-string command includes S0=2, the Services
Router applies S0=2.
■ If the initialization commands on the modem do not include a command in the
router’s init-command-string command, the router adds it. For example, if the
init-command-string command includes the command L2, but the modem
commands do not include it, the router adds L2 to the initialization commands
configured on the modem.
