IDLC Modem Profile in MUX State
Definitions
•
Modem profile – G24 modem settings such as s-registers and flex values.
•
GRLC profile – GRLC (PREMUX) settings such as s-registers and flex values.
•
GRLC default profile – GRLC (PREMUX) settings on power up.
•
When a new channel is established (open IDLC) its modem profile will be the GRLC default
profile.
profile.
•
When the G24 returns to PREMUX state from either MUX or MUX-INIT states, its modem
profile is the GRLC default profile.
profile is the GRLC default profile.
•
The two requirements above have an exception regarding the UART configuration – the
settings for UART port speed and flow control (AT&K and AT+CBAUD/AT+IPR). These
settings are set in PREMUX state only, and will be kept unchanged until the G24 returns to
PREMUX state. If an IDLC tries to change the settings it receives an OK response, but the
real value is NOT changed. When the G24 is in MUX state, these two settings have either the
values that were defined in PREMUX, or the value set by the AT+CMUX command. If a
value was set with the AT+CMUX command, it is retained even after returning to PREMUX
state.
