If the station wishes to return to the PRI trunk call while the Attendant is being called
1. Press the switchhook; the RECALL lamp goes out; the buzzer stops.
2. Ringback tone ceases; the station returns to PRI trunk call.
Service Conditions
1. This feature is available for incoming and outgoing ISDN trunk calls.
2. When the ATTENDANT CONSOLE [A-3] is in the Night mode, the transferring station receives reorder
tone.
3. The CALL TRANSFER - ATTENDANT - PRI feature allows a user, while participating in a two-party
connection (a two-party connection can comprise a station and a trunk), to call the Attendant so that the
Attendant can transfer the call or provide other assistance as required.
4. If all registers are busy and the user switchhook flashes, the flash is ignored by the system and the parties
remain connected.
Interactions
1. When the HOTLINE [H-1] set is equipped with a dial, the user switchhook flashes to get special dial tone
and dials 0. A ringback tone is provided, and the Attendant is notified of the call.
2. This feature can be used by a fully restricted station. The Attendant can transfer a fully restricted station
to another station only.
3. This feature is not operable when NIGHT CONNECTION - FIXED [N-1] or NIGHT CONNECTION -

C-99 Call Transfer - All Calls - PRI
C-99  Call Transfer - All Calls - PRI
General Description
This feature permits a user to transfer incoming or outgoing ISDN calls to another station without Attendant
assistance.
Operating Procedure
To transfer a call in progress
1. While connected with the first party, press the switchhook; receive special dial tone.
2. Dial the third party; receive ringback tone.
3. The user can then either:
a.) Hang up before the third party answers. The first and third parties are connected when third party
answers.
b.) Wait for third party to answer and announce the transfer while keeping the first party in a
CONSULTATION HOLD - ALL CALLS - PRI [C-100] condition. When the user hangs up, the
first and third parties are automatically connected.
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 is
returned to the transferring station. See VARIABLE TIMING PARAMETERS [V-1] feature for
additional timing choices.
2. In the case of outgoing calls (no answer supervision), this feature can 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. 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.) Two stations and one trunk
b.) One station and two trunks
5. The maximum number of simultaneous THREE-WAY CALLING [T-2] connections per system is
dependent on the quantity of conference-function circuits equipped (traffic engineered). The conference
function is included in the INT and TSW-INT cards.
6. 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’s connection 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 trunk, the trunk is disconnected if the timer times
out before the third party answers.
7. When transferring a call from a trunk or station (second party) to a trunk or station (third party), the control
station cannot answer the call during ringing. If the control station goes on-hook, during the ringing state,
the station or trunk (second party) is not connected to the third party’s line, and the controlling station will
be rung back again.

C-101 Call Forwarding - Intercept Announcement - 
PRI
General Description
This feature provides for interception of a called party number received via ISDN by DIRECT INWARD DIALING
[D-8] calls that cannot be completed (unassigned station, level, etc.). These calls are automatically routed to a
recorded announcement, informing the caller that an inoperative number was reached and giving the listed directory
number for information.
This feature permits a station originated call, upon encountering a restricted outgoing number or a trunk busy
condition, to automatically be routed to a recorded announcement informing the caller that all the outgoing trunks
are busy.
Operating Procedure
No manual operation is required, once this feature has been programmed in system data.
Service Conditions
1. This feature requires an announcement trunk and an announcement machine or a Digital Announcement
Trunk (DAT).
2. Only one ISDN call at a time can be connected to each announcement trunk. If a second ISDN call arrives
while the first is being processed, the caller will receive ringback tone until the trunk becomes idle.
3. If the outside party or Attendant forgets to hang up, the system will automatically disconnect in 30 seconds
(provided this is programmed in system data). If no disconnect timing is programmed, the outside party
will control disconnect.
4. This feature is provided on a per-tenant basis.
5. This feature is only available on DID calls.
6. The following call conditions, which cannot be completed, can be routed to intercept:
a.) Vacant level
b.) Unassigned telephone number
7. Only one common message can be provided for the different intercept conditions.
8. There is no method that exempts an individual ISDN DID from intercept.
9. This service is not available when the destination telephone number exceeds 13 digits.
10. A station dials the LEAST COST ROUTING - 3/6-DIGIT [L-5] access code and an outside number. If
that outside number is not listed in LEAST COST ROUTING - 3/6-DIGIT [L-5] tables (Outgoing Routing
Patterns, OPR), the call will be routed to an intercept announcement.
11. If a different message is required for each of the three intercept conditions, three trunks and three
announcement machines must be provided.
When encountering a restricted route
12. This service feature is valid when station to outgoing-trunk connection is restricted.
13. This feature is applied equally to all trunk routes in the system. It cannot be denied to some routes and
available to other routes.
14. This service is valid when a call is redirected to an outgoing trunk via CALL FORWARDING - OUTSIDE
[C-28]. The announcement is heard when the calling station is also a restricted station.
