manner as described above. A called conferee may leave the conference
voluntarily by going on-hook. The originator will terminate the conference by going on-hook.
6.2. 2.2.2
Preprogrammed Conference. A preprograuoned conference is one in
which a list of the identity and addresses of the conferees is predetermined and stored in the switch on which the originator is homed.
Normally, a conference involves two-way communications among the conferees.
In a broadcast conference, however, only the originator has the capability to transmit and receive, whereas the rest of the conferees have
receive only capability.
6.2.2 .2.2.1 Procedures. A preprogrammed conference may include subscribers of both the originating and ramote switch. If more than one
subscriber in the conference is served by the same remote switch, combining those subscribers should be accomplished using a conference
bridge in that remote switch. The list is assigned a two-digit identifier
unique
to
the originator.
This
two-digit identifier will be of the form
NX, where N and X are as defined in Section 1, Chapter 6. The NX aet
must be disjoint from the set of two-digit identifiers unique to that
subscriber used for compressed dialing, and disjoint from the set of
“meet-me” conference codes at the same switch.
The originator will be the conference controller and the conference
will not be affected by any conferee; other than the originator, going
on-hook. A short tone burst, denoted “conferericedisconnect, ” will be
used to alert the remaining conferees that a conferee has been disconnected from the conference. The originator shall be capable of recalling any conferee who has gone on-hook. Use of a conference notification
tone or announcement is under consideratlon.
6.2.2.2.2.2 Dialirm Sequence. A subscriber will originate a preprogrammed conference by going off-hook, entering the precedence
indicator, if any; the escape code, if applicable; the conference indicator
6C; and the two digit NX identification of the preprogrammed conference.
The switch, upon receipt of the complete signsling sequence, will automatically ring and connect all predetermined conferees in the stored
list .
Any level of precedence up to and including the higheat level
authorized the originator may be assigned to a preprogrammed conference.
When the conference is established, all conferees will be connected
at the assigned level of precedence of the conference, even though
their individually highest authorized precedence may be less than the
conference. Conference bridges shall be preemptable by a conference
request of higher precedence.
