Multiple Data Message Format
MDMF format transmissions consist of the following messages for each type of call:
Normal Call – Up to nine user-selected Call Setup components (Call Setup
Sequence – Normal)
Private Call (∗67 prefix by default) – Up to six user-selected Call Setup
components (Call Setup Sequence – Private)
Out of Area Call (∗87 prefix by default) – Up to six user-selected Call Setup
components (Call Setup Sequence – Out of Area)
Message Waiting Indicator On (∗50 prefix) – Up to six user-selected Call
Setup or Message Waiting components (No Ringing CID Sequence)
Message Waiting Indicator Off (∗51 prefix) – VMWI Off code
Note: The following operation will only apply if the unit is configured for US/Canada operation; all
other countries have as default, “Message Waiting” dial tone = continuous.
If the ∗50 prefix plus a phone number is dialed, the TLE will issue stuttered (“Message
Waiting” dial tone on the called line. If the ∗51 prefix plus a phone number is dialed, the
TLE will clear the stuttered dial tone on the destination line. Alternately, after a user dials
the audio message (411 default) from a line which has “Message Waiting” dial tone active,
the unit will revert back to normal dial tone and a Message Waiting OFF transmission will
be sent.
Note: “Data transmission not associated with ringing” (No Ringing CID) is not specified for
networks which use DTMF Caller ID transmission. If a user dials the ∗50 or ∗51 prefix
when DTMF CID is specified, the TLE will send a FSK Message Waiting transmission.
The following lists show the Call Setup and Message Waiting message components from
which the user may select for MDMF sequences. Which components are displayed
depends upon which Caller ID standard(s) has been selected. If all four lines are set to
the same standard, only those components listed for that standard will be displayed. If
more than one standard has been selected, the displayed list will contain the components
for all of the selected standards. If “Everything” is selected as a standard, the components
for all of the standards will be displayed.
Any component unique to a particular standard will be noted:
