stored will be erased. (No matter how many times the same number is dialed, it is stored only once.)
6. This service is not available if the LAST NUMBER feature key is not assigned on the D
term
7. When the Redial key is pressed after all of the stored numbers are displayed, the newest number (the one
displayed first) is displayed again, and continues in the same order.

L-44 LDN Night Connection - PRI
General Description
This service feature routes Listed Directory Number (LDN) calls from both ISDN/non-ISDN network to a
preselected station within the system, when the Night mode has been entered.
Operating Procedure
To answer LDN NIGHT CONNECTION calls
1. An incoming LDN call in Night mode is automatically routed to a preselected LDN NIGHT
CONNECTION station within the system.
2. The calling party receives ringback tone.
3. The ringing signal is sent to the LDN NIGHT CONNECTION station.
4. The LDN NIGHT CONNECTION station goes off-hook to answer the incoming call. If necessary, this
station can transfer the incoming call to another station within the system using the CALL TRANSFER -
ALL CALLS [C-11] service.
Service Conditions
1. The destination station can be assigned on a per LDN basis.
2. This feature is available for a maximum of 16 LDNs per tenant.

within the UCD [U-1] group are busy.

becomes idle at that time, the caller is connected.
c.) When several calls are waiting for the same destination station, first-in first-out queue is not
available.
8. When tenant switches to Night mode while LDN call terminates at the Attendant, the call is transferred to
destination station, depending on the dialed LDN number. If the destination station is in the states listed
below, the call cannot be transferred, and either NIGHT CONNECTION OUTSIDE - SYSTEM [N-17]
or TRUNK ANSWER FROM ANY STATION (TAS) [T-8] is activated; or caller waits in a queue after
receiving ringback tone.

station outside the system when the system is in Night mode.
Operating Procedure
To answer LDN NIGHT CONNECTION calls
1. An incoming LDN call in Night mode is automatically routed to a preselected LDN NIGHT
CONNECTION station outside the system.
2. The calling party receives ringback tone.
3. The ringing signal is sent out to the outside station.
4. The outside station answers the incoming call.
Service Conditions
1. The maximum number of digits in the destination number is eight. SPEED CALLING - SYSTEM [S-3]
can be used when more than eight digits are needed.
2. The destination station can be assigned on a per LDN basis.

is in non-ISDN network, OGC, OGCA, LCR and LCRC services are available. When the destination
station is in ISDN network, only LCR and LCRC services are available.
6. When the digits are sent to the destination station, the caller hears sender tone or does not receive any tone,
depending on system data (SYS-1 INDEX-6 b0).
7. When the destination station is busy, the incoming call is placed in a queue and the caller receives ringback
tone.
8. When the system switches over to Day mode, calls waiting in queue are connected to Attendant.

Miscellaneous Trunk Restriction - PRI M-72
M-72  Miscellaneous Trunk Restriction - PRI
General Description
This feature provides for incoming PRI trunks to be denied access to particular trunk groups such as FX ACCESS
[F-2], WATS ACCESS [W-1], CCSA ACCESS [C-14], TIE LINE ACCESS [T-3], exchange network, or PAGING
ACCESS [P-1].
Operating Procedure
MISCELLANEOUS TRUNK RESTRICTION - PRI is accomplished via system data programming at the
MAINTENANCE ADMINISTRATION TERMINAL (MAT) [M-18].
Service Conditions
1. Restricted call attempts can be either intercepted by the Attendant, or reorder tone can be initiated back to
the originating user.
2. The CALL TRANSFER - ALL CALLS [C-11] feature operates as follows:
a.) If the restricted station is the controller, the station cannot add a trunk from which this station is
restricted.
b.) If the restricted station line is not the controller, the controller cannot connect the restricted
station line to a trunk from which the station is normally restricted.
3. 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, thus allowing
Attendant completion of outgoing calls for restricted stations.
4. CALL TRANSFER - ALL CALLS - PRI [C-99]: If a restricted user calls another station, the called station
cannot use the Call Transfer feature to connect the calling station to a trunk group to which the restricted
station is denied dial access. If transfer is attempted, the controlling station is rung back.
5. TIE LINE ACCESS [T-3]: If the user accesses a tie trunk at a distant PBX, access to outside exchanges
can only be controlled by the distant PBX.
