transmit
Outgoing call SETUP messages do not
contain any Calling Party Number
Information Elements.
Outgoing call SETUP messages
contain Calling Party Number
Information Element with number set to
saved MSN (if a number is present).
Prevents digits being transmitted to the
POTS port upon call connection.
Upon connection of a call on the POTS
port, if there was a Called Party
Number Information Element present in
the incoming call setup message, the
digits are sent as DTMF tones to the
POTS port.
Once the CMX218 is de-activated it
stays de-activated until the network re-
activates it or an outgoing call needs to
be made.
The CMX218 checks to see if the ISDN
line is activated and Layer 2
communications can be made. It then
sets the ILFI pin
accordingly.
Resets all of the configuration variables
back to their default values.

The extent to which full CLI information is delivered to the POTS port will depend upon the CLI
facilities which have been implemented on the ISDN network.
Once the ‘
S
’ has been recognised, each digit pressed is then checked for validity as a configuration
sequence. If any digit pressed is not a valid configuration digit, all digits pressed so far will be
transmitted to the network in INFORMATION messages as Keypad Information Elements, until a ‘
#
’ is
entered (with the exception of ‘
S
#
’ being entered, see Keypad Operation below). If the first four digits
received are a valid configuration sequence then the configuration mode is entered. When a valid
configuration has been completed the CMX218 will send a single DTMF tone to the POTS port. If a
valid configuration sequence is received but subsequent digits are invalid, then subsequent digits
entered will be ignored and two DTMF tones will be sent to the POTS port.
If the port goes on-hook part way through configuration, it will cause any digits received so far to be
ignored. Configurations can be performed consecutively with the exception of the test function (where
the attached handset must be replaced immediately after the configuration has been audibly signalled
to the POTS port). All configurations entered will be retained after a power-down as they are stored in
the external EEPROM.
