Toshiba Perception 1 2 User Manual

							Infercepf 
DESCRlPTl()N The Intercept feature provides three types of intercept which act to re- 
route calls that cannot be completed because of system restrictions or 
dialing errors. Calls are rerouted to either the attendant or the overflow 
tone, depending upon the registration of each intercept type’s routing 
destination. 
OPERATION Intercepted calls will automatically be routed to either an attendant or 
overflow tone under the following three conditions: 
Intercept #I: This type of intercept will occur if the attendant has taken 
control of a Trunk Group (using the Trunk Group Control feature). 
Intercept #2: This intercept will occur when an incoming call comes in on 
either a DID, TIE, or CCSA trunk during Day Service, and the dialed 
station number has either been disabled or does not exist. In Version 
D.03 software, Intercept #2 has been enhanced to include the possible 
entries of a trunk port number or a standard telephone port number. A 
recorded announcement can be connected to these ports. When ICP2 
goes to this port, answer supervision will not be returned. 
Intercept #3: This type of intercept occurs when an incoming call comes 
in on either a DID, TIE, or CCSA trunk during Day Service in order to dial 
back-out over a system trunk. Any call which cannot be completed 
because of either a misdialed trunk access code or because of LCR 
access restriction, will automatically be rerouted. 
PROGRAMMING Each of intercepts #I, #2 (see Note 2), and #3 routes an intercepted call 
to either the attendant or the overflow tone, depending upon the specific 
assignment of each intercept type in the ICPl, ICP2, and ICP3 entries of 
the DSYS Data Block. 
NOTES: 
1. Whenever an intercepted call is presented to an attendant console, 
an INT (intercepo indication will display on the console’s ICI display 
panel. 
2. In Version 0.03 software, Intercept #2 has been enhanced to include 
the possible entries of a trunk port number or a standard telephone 
port number. A recorded announcement can be connected to these 
ports. When ICP2 goes to this port, answer supervision will not be 
returned. 
3. When the system is in Night Service, if an intercept has been 
programmed to go to the attendant, the calls will get overflow tone. 
RELATED FEATURES 1. Class of Service Restrictions (System). 
2. Toll Restriction (System). 
3. Trunk Group Access Control (Attendant). 
BENEFITS Intercept allows the customer to handle calls to invalid destinations. 
Callers can be informed that they have dialed an invalid number, and 
instructed how to reach the appropriate destination. Important calls are not 
missed, and customers receive proper treatment. This is also an important 
feature in regions in which the Public Utilities Commission requires a voice 
response on DID calls to unassigned directory numbers.

							Least Cost Routing (LCR) 
DESCRIPTION Least Cost Routing provides automatic routing over the customer’s trunk 
facilities based on a dialed number and a customer-specified routing 
selection. Based on this information, PERCEPTION will automatically 
select the least-costly route (trunk) for each particular call. If the least- 
expensive route is busy, then (if permitted by a station’s Class of Service) 
the next route in the ranked routing listing will be accessed. If this route is 
also busy, then the system will continue down the queue until a COS- 
allowable open trunk is accessed. If all trunks are busy, the caller may 
camp onto LCR, and a trunk will automatically be made available to him or 
her as soon as it becomes available. In this case, the system stores the 
dialed number and automatically outpulses it once the caller is again 
connected. LCR also provides access to trunks during a specified time of 
the day. 
OPERATION 1. Obtain dial tone. 
2. Dial the access code (RI B) . 
3. Dial the desired telephone number. 
4A. If a trunk (which is allowed by the caller’s LCR Class of Service) is 
available: 
n The call will be dialed automatically over the proper trunk. 
n Call progress tones will be heard. 
H Conversation may begin when the party answers. 
46. If no trunks (which are allowed by a caller’s LCR Class of Service) are 
available: 
H The caller will hear busy tone. 
n The caller may activate the Automatic Callback (ACB) feature 4 b 
PROGRAMMING 
n The telephone number will be dialed automatically when 
completed by the ACB feature. 
For programming Least Cost Routing information, refer to the 
PERCEPTIONehex Data Blocks DLCl (PAR, ACT, AOC) and DLC2 (RTB, 
MDT). Also refer to the PERCEPTION Least Cost Routing and Toll 
Restriction Programming Guide (Appendix 2). 
NOTES: 
1. PERCEPTION provides 15 separate LCR tables which can each be 
broken down by area and office code. Each LCR table can use up to 
six different routing steps, which can each be partitioned into three 
different time periods. 
2. LCR Class of Service (LCl, LC2, or LC3) is assigned to each station 
in the Class of Service Data Block (DCOS). 
3. Before Least Cost Routing is processed, the system will automatically 
assess whether or not the dialing station may perform the particular 
call, based on the station’s specific Toll Restrictions. 
4. In a tenant situation, either both tenants must share the same LCR 
program or one tenant must be denied LCR access. 
5. Dialed digits may be added or deleted through the MDT subprogram 
in the DLC2 Data Block.

The use of Least Cost Routing can reduce the cost of long distance calls 
by routing them over the proper (lowest cost) trunks and long distance 
carriers available to the customer. The automatic nature of the feature also 
eliminates the need for a station user to individually assess system trunk 
routes that are the least costly, as well as the need for the entrance of 
special trunk codes.

DESCRIPTION 
OPERATION 
PROGRAMMING 
RELATED FEATURES 
BENEFITS This feature enhancement allows the customer to now direct all 
international calls (011) to a preset route, chosen when the system’s Least 
Cost Routing (LCR) was configured. 
There are no special operating procedures. The customer has only to dial 
the 011 international number. However, the customer’s ability to make 
international calls is subject to his or her Class of Service and Toll Class 
restrictions. 
The Enhancement for the “011” Least Cost Routing is programmed in the 
DLCI Data Block. Also refer to the PERCEPTION Least Cost Routing and 
Toll Restriction Programming Guide (Appendix 2). 
NOTES: 
1. Any route can be used and the use of one route will not restrict it from 
being used in other features like LDI, LCR, etc. 
2. The chosen route should have a minimum of one valid trunk. 
1. Least Cost Routing (System). 
2. Toll Restriction (System). 
This enhancement enables the customer to use the Least Cost Routing 
feature when making international calls, thus reducing the cost of the calls 
by routing them over the proper (lowest cost) long distance carriers 
available to the customer. The automatic nature of the feature also 
eliminates the need for a station user to individually assess system trunk 
routes that are the least costly, as well as the need for the entrance of 
special trunk codes.

							Line Lockout 
DESCRIPTION Line Lockout releases station connections from the common system 
equipment in certain conditions, in order to keep lines and trunks free for 
access. Actual lockouts will occur after predetermined time periods, which 
have been registered in the system database, have elapsed. Specific 
conditions which bring about a Line Lockout include when a station 
terminal is not hung up at the end of a call (either after another party has 
hung up, or after busy tone has been accessed), and when a caller does 
not complete dialing within the time period allotted by lockout registration. 
OPERATION Electronic Terminal Line Lockout Conditions/Actions: 
A line lockout will occur when any of the following case conditions applies. 
The resultant actions of each noted condition apply exclusively to 
electronic/digital telephones: 
Case l-When a station user takes his telephone off-hook to place a call, 
and does not dial within the time period allotted by the Dial Pulse Time-out 
period which has been assigned within the DPT entry of the DSYS Data 
Block. 
n Resulting action: 
1. Dial tone is removed (if it has not already been removed). 
2. Overflow tone is provided until the Line Lockout Time-out period 
elapses. (The Line Lockout Time-out is defined within the LLO 
entry of the DSYS Data Block.) 
n Next resulting action: 
1. Overflow tone is removed. 
2. The call connection is released. 
3. The formerly-connected station is returned to its idle state and the 
station DN LED goes out. 
Case 2-When dialing has been completed, and either busy tone or 
overflow tone has been reached. In this case, lockout action will occur 
after the predetermined Line Lockout Time-out period has elapsed. 
n Resulting action: 
1. Busy or overflow tone is removed. 
2. The call connection is released. 
3. The formerly-connected station is returned to its idle state. 
Case 3-When either party disconnects a call, and the Line Lockout Time- 
out period has elapsed. 
n Resulting action: 
1. The call connection is released. 
2. The formerly-connected station is returned to its idle state. 
Standard Telephone Line Lockout Conditions/Actions: 
The following case conditions will produce a line lockout, with the noted 
actions applying exclusively to standard telephones. 
Case l-When a station user takes his telephone off-hook to place a call, 
and does not dial within the time period allotted by the Dial Pulse Time-out 
period which has been defined by the DPT entry of the DSYS Data Block. 
n Resulting action: 
1. Dial tone is removed (if it has not already been removed). 
2. Overflow tone is provided until the Line Lockout Time-out occurs.

							Line Lockouf 
n Next resulting action: 
1. Overflow tone is removed. 
2. The dialing station is made busy by the system, and is unable to 
receive calls. 
3. The station user must place his telephone on-hook in order to 
regain standard station operation. 
Case 2-When dialing has been completed, and either busy tone or 
overflow tone has been reached. In this case, lockout action will occur 
after the predetermined Line Lockout Time-out period has elapsed. 
n Resulting action: 
1. Busy or overflow tone is removed. 
2. The call connection is released. 
3. The formerly-connected station remains busy, and cannot receive 
calls. 
4. The station user must place his telephone on-hook in order to 
regain standard station operation. 
Case 3-When either party disconnects a call, and the Line Lockout Time- 
out period has elapsed. 
n Resulting action: 
1. The call connection is released. 
2. The station that remains off-hook will remain busy and will not be 
able to receive calls. 
3. The station user must place his telephone on-hook in order to 
regain standard station operation. 
PROGRAMMING The Dial Pulse Time-out and the Line Lockout Time-out are respectively 
defined in the DPT and LLO entries of the DSYS Data Block. 
NOTES: 
1. Line Lockout will not act upon a station whenever Call Waiting/Camp- 
on is in effect at that station. In such a situation, a calling station will 
receive only a consistent overflow tone. The Line Lockout silence 
period which normally follows this tone will not occur. 
2. Time-outs do not apply to a station-to-station ringing connection, 
unless the called station has been programmed for Call Forward-No 
Answer or Busy/No Answer. However, if an incoming call has been 
transferred to a station by an attendant, then the call will 
automatically be transferred back to the attendant when the system’s 
Ring-No-Answer Time-out occurs. This timing period also governs the 
length of time that a telephone will ring before forwarding to a 
registered Call Forward-No Answer or Busy/No Answer forwarding 
destination. 
3. There is no time-out which applies to calls that have been put on hold 
at an electronic/digital telephone. The Hold/EKT/DKT Park Time-out 
applies only to calls that have been put on hold at a standard DTMF 
(2500-type) telephone, or to calls that have been parked at an 
electronic/digital telephone. 
4. Calls which have been put on hold at a standard telephone will ring 
back after the Hold/EKT/DKT Park Time-out period has elapsed. This 
time-out is registered in the HLD entry of the DSYS Data Block.

							Message Center 
DESCRIPTION 
OPERATION 
PROGRAMMING 
RELATED FEATURES 
BENEFITS The Message Center feature provides customers with a means of storing 
messages when incoming calls cannot be personally answered. Two types 
of Message Center are available for PERCEPTION, they are a Message 
Center (MC) which can be the attendant, an attendant-position EKT/DKT, 
or EKT/DKT (both of which need an m button programmed), and Voice 
Mail (VM). 
The operation of a Message Center varies according to the Message 
Center type. 
Parameters for both types of Message Center are set in the DMCD Data 
Block. 
1. Tenant Service (System). 
2. Message Waiting (Attendant and Electronic/Digital Telephone). 
3. Voice Mail Connection (System). 
A Message Center provides a centralized point for system messages and 
prevents messages from being delayed, lost, or forgotten. It also 
eliminates the time that would otherwise be spent carrying message notes 
to individual desks and departments.

							Multiple Console Operation 
DESCRlPTlON Multiple Console Operation permits up to two attendant consoles to be 
used with PERCEPTION. Additionally, up to eight Attendant-Position 
Electronic/Digital Telephones and DSS/DDSS Consoles can be assigned, 
giving PERCEPTION a possible total of IO centralized answering 
positions. 
OPERATION Wh en a second console is equipped for operation, the following 
capabilities are provided: 
1. Incoming Call Treatment: 
If tenant service is not being utilized, and both consoles are idle, the 
system will automatically select one of the two consoles to receive the 
next incoming call. The console which is not selected will receive no 
indication of the call. Incoming calls will be served in the order of their 
arrival (unless incoming call priority has been selected) and are 
alternately distributed between the two consoles, unless one of the 
consoles is busy. In this latter case, the call will automatically be 
routed to the idle console. If both consoles are busy, the call will be 
held in the attendant queue and both consoles will receive a Call 
Waiting (CW) LED indication. When one of the consoles regains an 
idle loop, the calls in the attendant queue will be presented in the 
order in which they arrived. Refer to Tenant Service (8), Feature 5 for 
further information. 
2. Incoming Call Identification: 
Each incoming call that is presented to an idle attendant console will 
automatically prompt the display of the appropriate Incoming Call 
Identification (ICI) code, as well as the source and/or Class of Service 
of the caller. All pertinent displays will appear only at the console to 
which the call is presented. 
3. Attendant Queue: 
The attendant queue consists of calls which are waiting to be 
presented whenever a console becomes idle. The attendant 
console’s Call Waiting LED indicates that calls are waiting in the 
queue, although there is no indication as to how many calls are 
currently in the queue, or how long each call has been waiting. 
4. Call Waiting LED: 
The attendant console Call Waiting LED will light up on both consoles 
whenever one or more calls are waiting in the attendant queue (see 
Tenant Service (8) Feature 4). The CW LED gives one buzz tone to 
alert the attendant of a waiting call. 
5. Emergency Transfer: 
The console emergency transfer switch may be wired so that either or 
both consoles may activate an emergency transfer. 
6. Night Service: 
Either of the system’s two attendant consoles may independently 
control Night Service. Thus, if one console activates Night Service, 
then either that same console, or the other console may cancel the 
I-41  
						

							Mu/tip/e Console Operation 
service. When Night Service is activated, the attendant consoles are 
made busy to incoming calls. Night Service can initially be activated 
only when both consoles are idle. 
7. Timed Reminders: 
A call which must be returned to an attendant due to a system time- 
out, will be returned to the console which originally handled the call. If 
a call has been completed and then transferred back to the attendant, 
it will be presented to the first idle console. 
8. Tenant Service: 
Tenant Service permits calls which arrive over a particular trunk group 
to be answered by only one prespecified console. The use of this 
service modifies the above features (1 through 7) as follows: 
Feature 1: A trunk call will only be presented to the console which 
has been specified for call presentation. The call will 
remain in the attendant queue until that particular 
console becomes idle. ATT0 = Tenant 0; ATT1 = Tenant 
1. 
No Change. 
No Change. 
If the attendant console, to which an incoming trunk call 
is presented, is busy upon the call’s initial arrival, the 
call will be placed in the busy console’s attendant 
queue and the Call Waiting LED will light only on that 
particular console. The system’s other attendant 
console will receive no indication of the call. 
No Change. 
Each console controls Night Service for its own 
designated trunks. 
A call which must be returned to an attendant console 
because of a time-out, will be returned to the console 
which originally handled the call. A call which has been 
transferred to an attendant by a station, will be routed 
to the console which is assigned to that station’s tenant 
group.  Feature 2: 
Feature 3: 
Feature 4: 
Feature 5: 
Feature 6: 
Feature 7: 
NOTES: 
1. A Ring-No-Answer call will not return to the console at which it was 
initially presented. However, a call which is waiting via either Call 
Waiting or Camp-on, will return to its original attendant after the 
system’s predetermined Camp-on/Call Waiting Time-out period has 
elapsed. 
2. When Night Service is canceled, the console which initializes the 
cancellation will automatically be available to receive incoming calls. 
The other console will remain busy until its m button is 
pressed. 
3. If one attendant console employs Night Service, the service will 
automatically be activated for the entire system. In this situation, the 
Night Service LEDs on both consoles will light after either the 
m button on the other (non-initializing) attendant console is 
pressed, or after that console’s headset or handset is disconnected.
