T-2 Three-Way Calling
T-2 Three-Way Calling
General Description
This feature enables any user to add another party to an existing connection, establishing a three-way conference.
Even if the additional D
term user holds the call, THREE-WAY CALLING may be established. (This service is called
Consultation Hold.)
Operating Procedure
Procedure 1:
1. Press switch hook; first party is placed on Consultation Hold; receive special dial tone.
2. Dial the desired number; receive answer.
3. Announce the conference and press switch hook again.
4. The THREE-WAY CALLING is now established.
Procedure 2: 
1. While connected with the first party, press the switch hook; receive special dial tone. The first party is
placed on hold.
2. Dial the second party (D
term); receive ring back tone.
3. The second party answers; the CONSULTATION HOLD - ALL CALLS state has been entered.
4. The second party presses the HOLD key and the call in progress is held.
5. Press the switch hook and return to the original call.
6. The second party or another D
term station in the same Multi Line group answers the held call.
7. THREE-WAY CALLING is established.
Service Conditions
1. The originating party may hang up at any time. The remaining two parties will not be disconnected.
2. This feature may be activated during any call.
3. Any combination of parties (internal or external) may be included in a three-way call.
4. The maximum number of simultaneous three-way calls depends on the quantity of digital conference
trunks within the system. One digital conference trunk circuit card can handle 8 simultaneous three-way
calls.
5. The THREE-WAY CALLING feature is not restricted by the line class of service assigned to the user’s
line; thus, a fully restricted station can transfer a call to another station or the Attendant
When the Consultation Hold service is used:
1. Service restriction class of stations may be assigned at each station.
2. This service is not available when THREE-WAY CALLING has been established.
3. After the originating party presses the switch hook, the station can only go on-hook and press the switch
hook. The party in conversation can only operate on-hook.
4. This service is not available when the transferred call is held by CALL HOLD and so on.
5. When the additional station answers the held call, whether to send Override Tone or not depends on the
originating station service restriction class.
6. The Conference Trunk (CFT) function is required for the node which accommodates the station operating
a three-way conference within the FCCS network.
7. Three-Way Calling can also be established when using the trunk belonging to the remote node within the
FCCS network.

T-3 TIE Line Access
T-3 TIE Line Access
General Description
This feature allows any user dial access to a TIE Line. 
Operating Procedure
1. Lift the handset; receive dial tone.
2. Dial the TIE LINE ACCESS code; receive dial tone from the distant PBX.
3. Dial the desired extension number.
Operating Procedure
1. TIE LINE ACCESS may be denied to individual stations via CLASS OF SERVICE-INDIVIDUAL [C-
15].
2. The PBX system is equipped with either automatic or dial-repeating TIE trunks.
3. When a power failure occurs at the local NEAX2400 IMX (without reserve power backup), all TIE trunk
connections are lost.
4. Each TIE Line group can be arranged for DP or DTMF address signaling incoming and/or outgoing.
5. TOLL DENIAL [T-6]: The calling user is routed to reorder tone if an attempt is made to dial-access a call.
6. The NEAX2400 IMX can be equipped with senderized TIE trunks. Immediate start, delay, or wink start
signaling is available.
7. When a trunk group access code is dialed by a user, the TIE trunk group is used to index a trunk group
restriction table to determine if the call attempt is allowed. For each outgoing trunk group, the following
restriction options can be assigned per RSC:
a.) Indicates the TIE trunk is not allowed access to the trunk group dialed.
b.) Indicates the TIE trunk is allowed access (unrestricted).
c.) Indicates the station is allowed access but is restricted from making 0/1 toll calls or is code (3-
digit, 6-digit) restricted.
8. Two outgoing trunk group restriction tables are provided per system. The Direct Dial Access table is
indexed when a user dials the trunk group access code and the ATTENDANT CONSOLE [A-3] table is
indexed on Attendant completed calls. The restriction options per RSC can differ per table, allowing
Attendant completion of outgoing calls for restricted stations.
9. DTMF cannot be received on an incoming TIE Line call when the Signal Interface for Incoming route data
is set for Immediate Start.
Interactions
1. For senderized TIE Lines, see UNIVERSAL SENDER [U-3]. The ANND command must be programmed
for Senderized TIE Lines (normally for 4(OGC)).
2. If other services, such as STATION MESSAGE DETAIL RECORDING [S-10] and LEAST-COST
ROUTING-3/6 DIGIT [L-5] are to be used in conjunction with this feature, the AMND command must
be programmed. Go to the ASTP and AOSP command, if digit translation is required.
3. MISCELLANEOUS TRUNK RESTRICTION [M-3]: Restrictions to TIE trunks are determined by the
Route Service Class (RSC) assigned to the station.

T-6 Toll Denial/Toll Diversion
T-6 Toll Denial/Toll Diversion
General Description
This feature prohibits users from placing long distance calls over a specific group of trunks. Restricted calls are
routed to either an ATTENDANT CONSOLE [A-3] (diversion) or to an intercept tone (denial). 
Operating Procedure
No manual operation is required after this feature is programmed into system data.
Service Conditions 
1. TOLL DENIAL/TOLL DIVERSION is the industry-standard 0/1 type. 
2. Immediately after dialing any area code with a second digit of “0” or “1”, the user is restricted.
3. Restriction may be programmed to give the user a busy signal or to divert the user to the Attendant
Console. 
4. This feature may be applied to all types of trunks (DDD, FX, WATS), provided the same restrictions apply
to all trunks of the same type.
5. This feature is applied to individual stations on a route-restriction basis.
6. TOLL DENIAL/TOLL DIVERSION is set on a per-TENANT [T-12] basis.
7. The 0/1 Toll Denial and Toll Diversion feature cannot be used together for the same tenant.
8. The 0/1 Toll Denial and Toll Diversion feature is assigned on a per-line (RSC) Class of Service and/or
per-incoming TIE Trunk group basis. The feature, when provided, is applicable on a per-trunk group basis.
Interactions
1. TOLL DENIAL/DIVERSION is applicable only to RES 2 when assigning routes via Route Restriction
Index (RRI) 3.
2. LEAST-COST ROUTING-3/6 DIGIT [L-5]: For LCR(S) applications, allow the LCR Flag Route. The
route chosen via AOPR will then be governed by the RSC of the station. If the station is toll-restricted
from the route, TOLL DENIAL/DIVERSION will apply
3. TOLL DENIAL and TOLL DIVERSION cannot be used simultaneously in the same tenant.
4. ROUTE ADVANCE [R-6]: Station A dials a toll call by accessing route 1. Route 1 is busy and advances
to route 2. Station A is restricted from making this call on route 2.
5. PASSING DIAL TONE [P-2]: The Attendant Console cannot use the PASSING DIAL TONE [P-2]
feature to allow a toll restricted station to dial a restricted number. 
6. In System Data 1, Index 135, a seizure guard timer exists to protect the system from individuals who
attempt to defeat TOLL RESTRICTION/TOLL DIVERSION with rapid dialing. Leave as data “00” for
a default value of 1 second (RAM data is 1FH).
7. A station uses the OGC direct dial access to a route. The station is restricted via RES 0: Connection
Restricted. The station receives reorder tone.
