15. A user cannot answer an incoming call to the station in another CALL PICKUP GROUP or CALL
PICKUP EXPAND GROUP.
16. Even if a station has been assigned to the existing CALL PICKUP GROUP or CALL PICKUP EXPAND
GROUP by Physical Station Number, the station can also be assigned to the same CALL PICKUP
GROUP or a CALL PICKUP EXPAND GROUP via FCCS.
17. When the station holds a call (Switch Hook Flash or Call Hold) which terminated through FCCS link, the

PICKUP feature if assigned to a CALL PICKUP GROUP.
5. THREE-WAY CALLING [T-2]: CALL PICKUP can be used only after a THREE-WAY CONFERENCE

General Description
This feature permits a user to transfer incoming or outgoing Central Office and intra-office calls to another station
within the system without Attendant assistance.
(Series 7400 software enhancement) The user can set Camp-on function to the busy destination while transferring

CONSULTATION HOLD - ALL CALLS [C-17] condition. When the user hangs up, the first and
third parties will be automatically connected.
(Series 7400 software enhancement) To set the Camp-on by Station function to the busy station:
 Manual Operation

calling trunk party hears music on hold.
2. Dial the third party, and the third party is busy; receive busy tone.
3. Press the switch hook; receive special dial tone, and then dial the access code of CALL BACK; receive
service set tone.
4. Replace the handset. The station to be set Camp-on by Station (destination) hears Warning Tone. At this
time, the calling trunk party hears ringback tone.
5. The target station starts to ring when the target station lifts the handset.
6. The target station (called party) can call back to the trunk party directly by answering.
 Automatic Operation
1. While connected with the first party, press the switch hook; receive special dial tone. At this time, the
calling trunk party hears music on hold.
2. Dial the third party, and the third party is busy; receive busy tone.

Page 118NDA-24221, Issue 3
C-11 Call Transfer - All Calls
Service Conditions
1. The station performing the CALL TRANSFER - ALL CALLS can drop off the connection before the
called party answers. If the called station does not answer within the predetermined time, ringing signal is
returned to the transferring station. See VARIABLE TIMING PARAMETERS [V-1] for other selectable
timing choices.
2. In the case of outgoing calls (no answer supervision), this feature may be activated only after 18 seconds
have elapsed since the last digit dialed.
3. Outgoing calls with answer supervision may be transferred immediately after call is answered (no time
delay).
4. If all registers are busy and the user switch hook flashes, the flash is ignored by the system, and the parties
remain connected.
5. When TRUNK-TO-TRUNK CONNECTION [T-10] is provided with the system, an incoming or
outgoing network or TIE Line call may be transferred to an outgoing network trunk, if release signal is
provided from distant end. The user who transfers the call gives line control to the two remaining parties
upon hanging up. If the release signal is not provided, Call Transfer from trunk-to-trunk will not function.
6. The THREE-WAY CALLING [T-2] feature can comprise not more than three parties on one connection.
The three parties connected can be as follows: 
a.) three stations
b.) two stations and one trunk
c.) one station and two trunks.
7. The maximum number of simultaneous THREE-WAY CALLING [T-2] connections per system is
dependent on the quantity of CFT-function circuits equipped (traffic engineered).
8. When transferring a call from a station or trunk (second party) to another station (third party) the control
station can transfer the call during ringing. When the control station goes on-hook, the station or trunk on
hold is connected to the third party and hears ringback tone. A variable timer is set when the controlling
station goes on-hook. If the timer times out before the third party answers, the control station is rung back.
When transferring a call from a loop start DIT trunk, the trunk is disconnected if the timer times out before
the third party answers.
9. Reorder tone is returned to the user when the following actions occur: 
a.) the users line is restricted by outward or miscellaneous trunk restrictions by the class of service,
b.) the user dials the number of an unequipped line or termination is restricted (route restrictions),
c.) the user dials an invalid first digit.
10. When transferring a call from a station or trunk (second party) to another station (third party), the control
station can hang-up during ringing. If the third party’s line is busy, the control station will be rung back
right away and if the third party does not answer the phone in time (30 seconds), the control station will
be rung back after the time expires. In the case of transferring the call from a loop start DIT trunk, if the
third party does not answer before the time goes up, the trunk will be disconnected.
11.
(Series 7400 software enhancement) The Camp-on by Station cannot be set to the station via CCIS.
12.
(Series 7400 software enhancement) The Camp-on by Station is available when the destination station
is in the two-party connection except the following cases:
a.) When the transferred station is connected with the Attendant Console.
b.) When the transferred station answers another Camp-on call with the ANSWER key.
c.) When the transferred station is in Consultation Hold.
d.) When the station is the D
term in Exclusive Hold.

is set by manual operation (see Operating Procedure) because the service becomes effective when the
operating station is released from the connection:
a.) When the operating station is not released within the predetermined time period after receiving
service set tone, the service which has been set will be ineffective. And the operating user hears
busy tone.
b.) When the transferred destination station becomes available before the transferring station is

tone), the trunk incoming call is connected with the destination station after the operating station
(mediate party) replaces the handset.
c.) When the transferred destination station becomes LINE LOCKOUT condition or the destination
becomes make busy before the transferring station is released from the connection after the
service was set (after the operating user hears service set tone), the called station (mediate party)
