Toshiba Perception 1 2 User Manual

							Swifched Loop Terminafion 
DESCRlPTlON Switched Loop Termination refers to PERCEPTION’s method of routing 
incoming calls to an attendant console. Specifically, neither trunk nor 
station calls appear directly at a console. Instead, each call that requires 
attendant assistance is automatically switched to one of the console’s loop 
buttons (the lowest-numbered idle loop button is selected). Each attendant 
console is initially equipped with four m buttons, and one corresponding 
LED per loop. An m button provides the attendant with an access to the 
speech connection that is currently on a loop. 
OPERATION 1. When a call rings in at the attendant console, it will be connected to 
the source (SRC) side of an attendant loop circuit. 
n Simultaneously, the LED which corresponds to the console’s 
lowest-numbered idle loop will flash. 
H The attendant can answer the incoming call by pressing the 
associated m button. 
2. Pressing the Release (m button completes call processing. 
n The console loop becomes idle, and is available to receive new 
calls. 
n The caller who had been connected to the loop, will be 
transferred to the desired destination. 
3. Each attendant console is equipped with either four, six, or eight loop 
buttons, numbered LPK-1 - LPK-8. 
H In most cases, an occupied loop will be freed for a new call once 
the attendant presses the m button. 
n Calls that are not subsequently completed (Ring-no-answer calls, 
Camped-on calls, etc.), will return to the attendant queue after a 
specified time interval. 
4. A call will be held on a console loop under either of the following two 
conditions (both conditions involve an attempted call connection 
between an incoming and an outgoing trunk): 
a. When an attendant attempts to establish a call connection via a 
trunk-to-trunk connection, which lacks the supervision to release 
automatically. 
b. When the system automatically decides to hold a call, after 
assessing the descriptive parameters of each involved trunk. 
(Refer to Trunk-to-Trunk Connections for detailed parameter 
descriptions.) 
PROGRAMMING See Note 2. 
NOTES: 
1. Each console requires one circuit on a NEKU PCB (for 
PERCEPTION,,,) or a DEKU PCB (for PERCEPTION I & II). 
2. When an attendant utilizes the Lockout feature (when LKO = Yin the 
DATT Data Block), the attendant will be denied access to any loop, 
on which an established call is currently being held (for example, for 
Serial Call and Conference purposes). The attendant may, however, 
access any recall from an involved held-call member.

							Switched Loop Termination 
BENEFITS Switched Loop Termination allows a console loop button to become idle, 
immediately after a call is released. This eliminates call blocking and 
enables an attendant console to receive more calls.  3.

							Through Dialing 
DESCRlPTlON Through Dialing enables a station and TIE-line users to make calls that 
are ordinarily prevented by Class of Service and Toll Restriction 
limitations, by using the attendant as an intermediary dialing point. Once 
an attendant is accessed, the restricted calls can then be performed. 
OPERATION After receiving a call from a requesting station or a TIE-line user, an 
attendant can complete a restricted call by performing one the following 
series of actions: 
To Handle Through Dialing Requests: 
1. An incoming call signal will be heard. 
n ICI will display OPR, SRC and COS will be displayed, and the 
LPK LED will flash. 
2. Press the appropriate [a3 button. 
H The LPK LED will light steadily, the console signal will stop, and 
you will now have a voice connection with the calling (SRC) party. 
3. Dial the desired trunk access code or the LCR access code (11 m 
n The EXCL SRC LED will light steadily, DEST will display the trunk 
and member number. 
n STATUS will display TLK, the voice connection with the calling 
party will be broken, and you will hear trunk dial tone. 
4. Press them button to transfer trunk dial tone to the station. 
n The RLS LED will light, and the calling (SRC) station may now 
dial out on the selected trunk. 
NOTE: Restriction will NOT be in effect at the station for the duration of 
the call. 
PROGRAMMING Through Dialing is automatic. Trunk access codes are defined in the 
DTGP Data Block, and the LCR access code is defined in the DACD Data 
Block. 
RELATED FEATURES 1. Intercept (System). 
2. Push-Button Dialing (Attendant). 
3. Non-Delayed Operation (Attendant). 
BENEFITS Through Dialing saves valuable time, by allowing an attendant to pass 
Central Office dial tone to restricted stations, so that users can place their 
own calls. The feature is also highly beneficial in high-traffic situations, or 
when individuals must make calls from various (often restricted) 
telephones within a business facility.

RELATED FEATURES 
BENEFITS 
;,! 
The attendant console’s SRC and DEST displays show the identity of any 
trunk that is currently connected to the console. Each display consists of 
three characters. The first character shows the connected trunks access 
code, while the remaining two indicate the trunks member number. 
1. Calling Source Number: This display is a 3-character, 7-segment LED 
display which indicates the station or directory number of the calling 
station or trunk. 
2. Call Destination Number: This display is a 3-character, 7-segment 
LED display which shows the station or directory number of the 
station or trunk called by the attendant. 
NOTES: 
1. A trunk’s member number is the second half of the Group/Member 
Number (GMN), that is entered within the DTRK Data Block to 
identify each individual trunk. 
2. If a trunk’s access code consists of 2 or 3 digits, only the first digit of 
the access code will be displayed. 
Digital Information Display (Attendant). 
The Trunk Equipment Number Display identifies the specific trunk 
connected to the console at any one time. It is helpful in identifying any 
non-working trunk. This reduces repair time, since the defective trunk has 
already been determined and can quickly be replaced.

							Trunk Group Access Confrol 
4-53 
DESCRIPTION 
OPERATION 
PROGRAMMING Trunk Group Access Control allows an attendant to seize control of any 
trunk group, at any time. Once a trunk group has been seized, its 
corresponding Trunk Group Busy (TGB) LED on the attendant console, 
will light steadily. This indicates that no outgoing calls can now be made 
through that trunk group, unless they are made or extended directly from 
the attendant console. Any station or TIE trunk without the Attendant 
Control Override capability, which attempts to access such a restricted 
trunk group, will either be intercepted by the attendant, or will receive 
overflow tone. 
To Take Control of a Trunk Group: 
1. Press an idle m button. 
2. Dial 11 I, followed by the desired trunk group’s access code. 
H The trunk group’s corresponding TGB LED will light steadily. 
3. Press the m button. 
To Release Trunk Control (TGB LED is On): 
1. Press an idle m button. 
2. Dial u 1 I, followed by the desired trunk group’s access code. 
H The trunk group’s corresponding TGB LED will go out. 
3. Press them button. 
1. Any station or TIE-trunk caller who attempts to place a call to a 
deactivated trunk group, will either be intercepted by the attendant, or 
will receive overflow tone. 
n This intercept option is controlled by the ICPl entry within the 
DSYS Data Block. 
H The specific programming options are as follows: 
ICPl = ATT (attendant console). 
ICPl = OFL (overflow tone). 
2. A station or TIE trunk, whose specified Class Of Service (COS) 
allows Attendant Control Override, is able to override trunk-group 
deactivation, and will be permitted access to the desired trunk group. 
n Each COS level is defined within the DCOS Data Block. 
H Specific allowances and restrictions customize each COS level 
(0 - 15). 
H A specific COS level is assigned to each station, via the COS 
entry of the station’s DEKT, DSlT, or DTGP Data Block. 
NOTES: 
1. When all trunks in a trunk group are busy, that group’s associated 
TGB LED will light steadily. 
2. If a station places a call to a deactivated trunk group, and that call is 
intercepted by the attendant, the console’s Incoming Call 
Identification panel will display INT 
3. Attendant Control Override will override any trunk deactivation, 
unless this feature is specifically denied by a station’s designated

							Trunk Group Busy Indication 
DESCRIPTION 
OPERATION 
PROGRAMMING 
RELATED FEATURES 
BENEFITS Each attendant console is equipped with ten Trunk Group Busy (TGB) 
LED indicators. 
Trunk Group Busy LEDs are numbered 0 - 9, and they provide a visual 
indication of the status of each trunk group. Possible indications are as 
follows: 
1. LED off = At least one trunk is idle. 
2. LED on steadily = Attendant has utilized Trunk Group Access Control. 
3. LED flashing = All trunks are currently busy. 
Each Trunk Group Busy LED indicator (0 - 9) indicates the status of its 
corresponding trunk group (For example, TGB LED 0 = Trunk Group 0, 
TGB LED 1 = Trunk Group 1, etc.). Each trunk group is assigned a 
number and defined within the DTGP Data Block. 
NOTE: Although the system permits the formation and use of up to 16 
trunk groups, only the first 70 (0 - 9) can be represented by a console 
TGB LED. 
Trunk Group Access Control (Attendant). 
Trunk Group Busy LED indicators allow an attendant to monitor the status 
of individual trunk groups. This saves the attendant valuable time, since 
access to busy trunk groups need not be attempted. It also encourages 
trunk group efficiency, by identifying groups that require additional trunks.
