levels occupy another. Therefore, a voice number of 310 can have a data number of 210.
2. The LEN of the data extension is assigned as TEC 13. The voice LEN is assigned as a TEC 12. The voice
and data LENs are associated as follows:
3. The data extension number is automatically assigned to the key programmed as DATA.
4. For Data Terminals, assign RSCs that allow access to the routes to be used for data transmission, and the
SFC or the data terminal should include SFI 11 = 0, Data Privacy.
5. Only DTE-to-DTE direct internal connections are possible. The DTE would then be set for AUTO answer

S-56 Station-Controlled Conference - CCIS
S-56 Station-Controlled Conference - CCIS
General Description
This feature allows any PBX station to establish a conference through CCIS. The conference can be any combination
of stations and trunks (on-network and off-network parties).
Operating Procedure
To establish a conference call: 
1. The user wishing to establish the conference (Conference Leader) calls each party to be included and
advises them of the conference.
2. All participating stations then call the conference extension number or the Conference Leader, who will
transfer them to the conference number. 
3. The conferees are automatically connected.
4. Any push-button station within the conference can dial “9” to lock out additional parties using the MMCB
model. 
To release from a conference call:
1. If any pushbutton station in the conference dials “0”, all conferees will be disconnected. Otherwise, the
conference is terminated after all parties have hung up. 
2. Any individual conferee can release from the conference call by hanging up. All other conferees will
remain connected.
Using the PA-CFTB, the conference leader can dial “0” to lock out additional parties. Dialing “0” again will allow
more parties to be connected. If the conference leader dials “#”, all conferences will be disconnected. Otherwise, the
conference is terminated after all parties have hung up.
Service Conditions
1. Conference Units are designed to provide adequate amplification, but the condition of the Central Office
connections will affect transmission.
2. Conference Unit extension numbers should be placed in a STATION HUNTING-TERMINAL [S-9]
group. Only the Pilot number of this group should be published.
3. Each Conference Unit can provide up to an eight-party conference. 
4. Override services, such as BUSY VERIFICATION [B-3, B-9], ATTENDANT OVERRIDE [A-7], or
EXECUTIVE RIGHT-OF-WAY [E-1, E-8], are denied to stations engaged in a conference call. 
5. The following additional hardware is required:
 External Conference Unit MMCB
 PA-16LCQ or PA-16LCBE circuit card
6. The PA-CFTB may be used instead of the MMCB. The PA-16LCBE or PA-16LCQ is not required by the
PA-CFTB. 
Interactions
The PA-16LCBE or PA-16LCQ circuit card provides a momentary open for all 16 circuits. This is required to
provide a release signal when line circuits are connected to external equipment such as conference and page units.
This keeps reorder tone from being sent to the conference unit. This is not used in conjunction with a PA-CFTB.
