							Tandem Switching 
The possible types of tandem connections are as follows: 
H Incoming Call Facilities. 
n TIE Trunk Loop, dial repeating. 
n Incoming dial, outgoing automatic E & M. 
Outgoing Call Facilities: 
H TIE Trunk Loop, dial repeating. 
n Incoming dial, outgoing automatic E & M. 
H CO Trunk, loop start. 
n Ground start. 
n Paging trunk (see Note 1). 
6. Any tandem call which does not utilize TIE trunks, requires the 
intervention of either an attendant or a station to perform trunk 
connections (see Trunk-to-Trunk Connections). Such calls may 
originate from either a CO/Fx/wATS or a DID trunk. If an attendant 
attempts to make a connection which is prohibited, the incomplete 
call will be held on the console loop. Prohibited connections which 
have been set up by a station, will be disconnected once the station 
goes back on-hook. 
PROGRAMMING 1. See Operation, step 5. 
2. All trunk parameters are programmed through entries in the DTGP 
and DTRK Data Blocks. 
NOTES: 
1. The conversion from DTMF dialing tones to dial pulses, (or vice 
versa), is automatically provided whenever trunks of different dialing 
classes are connected in tandem (see Tone Dialing-to-Dial Pulse 
Conversion). 
2. It should be noted that if the system’s signaling-starting arrangement 
is set as immediate (IMM Start), then this may occasionally cause 
voids in digit acknowledgement, since the connected tandem system 
or central office may operate on a different starting-time frame (e.g., 
wink, or delay). Start arrangement should be the same on both ends. 
3. The same COS and Toll Restrictions that apply to stations also apply 
to TIE trunks. 
4. Whenever a station places a tandem call to another PBX, 
PERCEPTION will not verify Class of Service and Toll Restriction 
assignments which apply to TIE-trunk lines. If the connecting TIE 
trunks are governed by such restrictions (e.g., the specification of 
certain TIE trunks for only incoming T/E calls), then these stipulations 
will be imposed at the distant PBX.

							Tandem Switching 
BENEFITS 
T d an em Switching allows PERCEPTION to be part of a larger network, 
since every network member does not need to have its own trunks for all 
of its specific calling purposes. Rather, tandem switching allows trunks to 
be shared between network members. This allowance can eliminate the 
need for the duplication of both foreign exchange lines and OCC services, 
and thus can provide considerable cost savings in addition to its inherent 
advantage of network flexibility.

							Tenant Service 
DESCRIPTION T enant Service allows a single PERCEPTION system to be shared by two 
customers. This set-up provides the advantages of dual usage (cost 
savings, space requirements, etc.), while also providing the individual 
system feature with unique attendant console operation. The station 
members of each tenant group are able to access system features and 
trunks (as allowed by their specific Class of Service), and may also place 
calls to cross-tenant members. 
OPERATION 1. The employment of Tenant Service primarily affects the operation of 
attendant consoles. Specifically, in an application which utilizes two 
attendant consoles without Tenant Service, the consoles alternatively 
share the handling of incoming and outgoing calls. In a tenant 
situation, however (when TEN = Y in the DSYS Data Block), the 
consoles do not share the call load, but rather, handle only the calls 
that are addressed to and from the members that are in each of their 
specific tenant groups (0 or 1). This differentiation applies to station- 
to-station calls, Operator (0) calls, and all incoming and outgoing 
CO/FX/WATS trunk calls. 
2. Since the station members of each tenant group may place calls to 
each other, it is important to note that PERCEPTION’s station- 
numbering plan must be continuous. There can be no numbering 
duplications. 
3. The trunk groups which are contained within a PERCEPTION system 
are registered in a single overall trunk group arrangement. The ability 
for each tenant station member to access the different group 
members of this arrangement is governed solely by each station’s 
Class of Service assignment. Thus, it is important to note that trunk 
group access codes must also be assigned in an overall 
arrangement. Each trunk group.must have its own unique access 
code, which is used universally between tenants, in order to access a 
particular trunk group. Once a station enters a particular access code, 
PERCEPTION will automatically correlate the access code with its 
respective trunk group, and in turn, will reference each station’s COS 
to decide whether or not access will be allowed. 
4. In D.O1 software and above, a second NPRU must be installed to 
provide two UNA zones in Tenant Service. In a non-tenant system, 
only one UNA zone is possible. 
PROGRAMMING 1. Tenant Service is assigned in the TEN entry of the DSYS Data Block 
(TEN = Y). The assignment of this service will automatically convert 
an ordinary dual-attendant-console load-sharing set-up, to the call- 
differentiating tenant arrangement. Specific attendant-to-tenant 
assignment is noted below: 
ATT 0 = TEN0 
ATT 1 = TEN1 
2. A station is assigned to a specific tenant group through the 
registration of either a 0 or a 1 in the TEN entry of the DEKT/DSTT 
Data Blocks. 
l-65  
						

							Tenanf Service 
3. A trunk is assigned to a specific tenant group through the registration 
of either a 0 or a 1 in the TEN entry of the DTGP Data Block. 
4. When a system is programmed for Tenant Service, a separate 
Universal Night Answer (UNA) zone can be assigned to each tenant 
(UNAO = TENO; UNAl = TENI) in the DSYS Data Block. When dual 
UNA zones are assigned, any station user (regardless of tenant 
membership) may dial the same UNA access code, or depress a 
UNA feature access button in order to obtain trunk calls which are 
designated specifically for their particular tenant. To allow this 
capability, a second NPRU PCB must be installed. Systems which do 
not employ Tenant Service may only utilize one UNA zone. 
NOTE: When a system is divided into tenant partitions, this causes 
complex feature interactions. Thus, before Tenant Service is employed, 
each tenant party should be carefully reviewed to make sure that the 
desired functions and results of the pending tenant arrangement can be 
achieved. 
RELATED FEATURES 
BENEFITS All. 
Tenant Service allows two customers with the same communication needs 
to share the features of a single PBX system, rather than have to maintain 
their own separate systems. This saves both money and space since only 
one main system needs to be installed. Tenant Service provides the 
benefits of dual usage, while allowing each tenant its own unique call- 
differentiating attendant console.

							TIE Trunks 
DESCRIPTION 
OPERATION 
PROGRAMMING TIE trunks allow a I- or 2-way interconnecting between systems which are 
within the same communication network. PERCEPTION utilizes E & M 
signaling, Type I and Type II, 2- and 4-wire on (PERCEPTIONehex only) 
interface trunks, which may be specified to transmit either dial-pulse 
signals or DTMF tones. A TIE trunk may be used either to make a direct 
connection between a station, or attendant and another network member, 
or as a connective means to another trunk which is contained within the 
network member system. (Refer to Tandem Switching for further 
information regarding this latter capability.) 
See Tandem Switching. 
All TIE trunk parameters are specified within the DTGP and DTRK Data 
Blocks. Class of Service groups for both stations and TIE trunks are 
defined within the DCOS Data Block. 
NOTES: 
1. The FCC Facility Interface Code for the PERCEPTION E & M TIE 
trunk (DEMU/NEMU) is TL 1 I M. 
2. The same COS and Toll Restrictions which apply to stations also 
apply to TIE trunks. 
3. Whenever a station places a tandem call to another PBX, 
PERCEPTION will not verify COS or Toll Restriction assignments 
which apply to TIE-trunk lines. If the connecting TIE trunks are 
governed by such restrictions (e.g., the specification of certain TIE 
trunks for only incoming TIE calls), then these stipulations will be 
imposed at the distant PBX. 
4. PERCEPTION does not permit External-zone or Internal-group pages 
to be made across a TIE trunk. 
5. PERCEPTION can be programmed to perform number translation 
and/or digit absorption on incoming dialed numbers which arrive over 
either a TIEKCSA, or DID trunk. The programming for either of these 
capabilities is performed in the OAB, IAB, TRN 1, and TRN2 entries of 
the DTGP Data Block. A description of each of these separate 
parameters and each of their different entry options is described as 
follows: 
OAB (Outgoing Absorb Digits)-This parameter identifies any 
outgoing dialed digits which are to be ignored by the system for Toll 
Restriction purposes. The registration of specific digits for outgoing 
absorption means that if these particular digits are dialed by a station 
user, they will not be considered as part of the dialed number. 
TO PROGRAM: Enter either the number of digits which are to be 
absorbed or NONE. A maximum of 2 digits can be absorbed by 
the system. 
IAB (Incoming Absorb Digits)-This entry defines the number of 
digits that are to be stripped off of an incoming dialed number, which 
arrives over either a TIE/CCSA or DID trunk. 
TO PROGRAM: Enter either the number of digits which are to be 
absorbed (maximum: 2 digits), or NONE.

BENEFITS 
TRNI (Translated Number I)-The TRNl entry is used to specify 
any absorbed digit (IAB) which is to be translated into another digit 
(or digits). (See examples following TRN2.) 
TO PROGRAM: Enter either X # r: or X # YY: 
X = The digit which is to be translated (when two digits are 
absorbed, only the second digit will be translated). 
Y or YY = The digit or digits which are to take the place of the 
originally-absorbed digit (X). 
TRN2 (Translated Number 2)-This parameter is also used to speci& 
an absorbed digit (IAB) which is to be translated into another digit or 
digits (See examples).

TIE Trunks enable PERCEPTION to integrate into a private networking 
arrangement, utilizing the most commonly-used types of TIE trunking. The 
expense of calling between nodes in the network is reduced, because of 
the elimination of toll calls; and calls to external directory numbers in the 
area/office codes of the nodes may be less expensive when made across 
TIE trunks. Since TIE trunk calls can access features and stations in the 
distant systems, less time and attendant assistance are required.

							To// Restriction (69Digit) 
DESCRIPTION Toll Restriction enables the end-user to control the outbound calling 
capabilities of individual stations. There are 10 available Toll Restriction 
classes (0 - 8 and NONE), which determine the long distance numbers 
that individual station users may call. PERCEPTION provides true Six-digit 
Restriction, meaning that it can screen both area and office codes, as well 
as 0 and 1 as the first digits dialed, to provide the end-user with maximum 
flexibility in configuring outbound calling capabilities for individual station 
users. The registration of NONE in a Toll Restriction assignment allows 
unlimited dialing privileges. However, if a station’s Toll Restriction 
assignment denies the placement of a particular call, a system attendant 
has the ability to bypass that governing restriction. 
OPERATION 1. The use of Toll Restriction stipulates the dialing privileges of specific 
area codes and/or off ice codes. 
2. The examination of Toll Restriction stipulations is performed 
automatically by PERCEPTION, and is indicated through the 
system’s follow-up procedures. Specifically, when a station user 
attempts to dial a number which contains an area or office code which 
is denied through Toll Restriction, he or she will receive overflow tone. 
If Direct Trunk access is used to place a call to an area which is 
governed by an area- or office-code restriction, the system will 
indicate the restriction by not furthering the attempted call. Likewise, 
PERCEPTION will indicate its recognition of Toll Restrictions which 
affect trunks, by bypassing any restricted trunk while performing 
Least Cost Routing. 
PROGRAMMING 1. Each station and TIEKCSA trunk is assigned a specific Toll 
Restriction class (0 - 
8 or NONE) in the TOL entry of the DSTT, 
DEKT, and DTGP Data Blocks. 
2. Toll class restrictions are defined within the DTOL Program. 
NOTES: 
1. Toll Restriction can be applied to series of numbers which contain up 
to six digits. This allows for the restriction of the following: 
a. Area codes and/or home-office codes. 
b. Area codes/office codes (within the respective area) and/or 
home-off ice codes. 
2. Toll Restriction classes 0 - 7 may be used to restrict selective 
operator calls, international calls, and/or long distance assistance 
(555) calls. Toll Restriction class 8 is reserved for dialed numbers 
which begin with either a 0 or 1, while Toll Restriction class (NONE) 
places no restrictions on outgoing calls. 
3. Toll Restriction works together with Class of Service in forming the 
allowance/denial framework within which each individual station is to 
operate. While Toll Restriction is used to allow or deny the dialing of 
particular area/office codes, Class of Service is used to either permit 
or deny feature-access privileges. 
4. For further information regarding Toll Restriction, refer to the Least 
Cost Routing and Toll Restriction Programming Guides, 
5. Toll Restriction is not applied to calls made over Private Lines. 
6. System Speed Dial does not override Toll Restriction.

RELATED FEATURES 1. Class of Service Restrictions (System). 
2. Intercept (System). 
3. Least Cost Routing (System). 
4. Direct Outward Dialing (Station). 
BENEFITS Through its denial of specific area/office codes to particular stations, Toll 
Restriction provides access to only those station users who require it. This 
ability is beneficial in preventing the unauthorized dialing of long distance 
calls, which can dramatically reduce the end-user’s long distance calling 
expenses. Such restrictive measures act to further customize a system to 
meet the needs of a particular customer, and are a major means of cost 
control.

							Toll Resfricfion/C/ass of Service Override Code 
DESCRIPTION -I-I-, is single code, when input prior to dialing an outgoing number at any 
telephone in the system, changes both the Toll Restriction Class and the 
Class of Service programmed for that station to 0 for the duration of a 
single call. Once that call is completed, the Toll Restriction Class and 
Class of Service programmed in the system data base for that station are 
reapplied. This feature enables executives and other persons requiring 
specialized, outgoing calling capabilities to make calls from any telephone 
in the system, regardless of the restrictions that are normally applied to 
that telephone. This feature can also be applied to telephones located in 
unattended or unsecure locations to prevent telephone abuse. Toll 
Restriction Class 0 and Class of Service 0 can be set in system 
programming to apply the features and restrictions the customer wishes to 
apply to override calls. 
Although only one override code is provided by PERCEPTION software, 
code entry can be customized to require multiple or individualized override 
codes by activating Forced and Verifiable Account Codes in Class of 
Service 0. In this case, when a person enters the override code at a 
station and then dials an outgoing number, the system will force an 
account-code entry and then verify the code entered, before permitting the 
call. Thus, not only will individual persons have unique override codes, but 
the account-code number output with the SMDR data will also identify the 
exact person making the override code, providing additional control and 
security for the customer. 
OPERATION Ty lJr;z: ~a;;~tionlClass of Service Override:

PROGRAMMING This feature is available only with D.04 and later versions of software. 
1. The default Toll Restriction/Class of Service Override code (1 10) 
can be changed in the Access Code (DACD) Data Block. 
2. Class of Service 0 is programmed in the Class of Service (DCOS) 
Data Block. Toll Restriction is programmed in the Toll Restriction 
(DTOL) Data Block. 
RELATED FEATURES 1. Account Codes: Forced, Verifiable, Voluntary (System). 
2. Class of Service (System). 
3. Station Message Detail Recording (System). 
4. Toll Restriction (System). 
BENEFITS This feature increases telephone security by allowing the end-user to 
assigned, restricted outgoing call and feature privileges to specific 
stations, while still permitting particular individuals to override those 
restrictions as required.

							Tone Dialing 
DESCRIPTION T one Dialing capability permits PERCEPTION to accept audible tones 
from DTMF telephones (the 2500-series). Once received, these tones can 
be used to make a call connection between any calling telephone and any 
type of trunk. PERCEPTION can also generate and receive DTMF over 
central office and private network trunks. Additionally, PERCEPTION can 
convert electronic/digital telephone dialing signals into tone-dialing signals, 
to enable connection to a tone-dialing trunk, voice mail system, or other 
DTMF-activated device. The system also has the capability to convert 
tones into dial-pulse signals in order to connect the calling station with a 
dial-pulse class trunk (see Tone Dialing-to-Dial Pulse Conversion). 
OPERATION 1. In order to accommodate DTMF telephones, PERCEPTION is 
equipped with DTMF receivers (DRCWFRCLVNRCU PCB) which 
serve to translate tone-dialing signals into PERCEPTION signaling 
messages. 
2. In order to establish an outgoing trunk call, PERCEPTION will first 
access an outgoing trunk, and will then generate and outpulse the 
appropriate dial pulse or DTMF signals which the trunk requires. 
PROGRAMMING 1. The dialing-type (tone or dial-pulse) designation for standard 
telephone stations (DSTWNSTU circuits) is specified in the DLG 
entry of the DSTT Data Block. 
2. Trunk dialing parameters are specified within the DTRK Data Block. 
3. See Note 1. 
NOTES: 
1. While dialing from a standard-DTMF telephone, the transmit 
connection from the station to an outgoing trunk is disabled, and the 
station is connected to a DTMF receiver. During this time, the caller 
will be involved in a listen-only connection. Once the last digit has 
been dialed, and once the Push-button time-out period has elapsed, 
a Z-way connection will automatically be established. Once this 
occurs, any further dialing from a DTMF telephone (for security-code 
entrance, etc.) will be transmitted via the established voice path. The 
Push-button Time-out period is specified in the PBT entry of the 
DS YS Data Block. 
2. A station line which has been designated for tone dialing may still 
receive calls which are transmitted via dial-pulse signals. It is 
important to note, however, that a station which does not require tone 
dialing (i.e., a station that makes calls mainly to dial-pulse 
destinations) should not be designated for tone dialing, since this 
would unnecessarily promote extra traffic on the system’s DTMF 
receivers.
