Toll Restriction
Station users can be individually restricted from making toll calls, according to one of the three toll 
restriction schemes which are:
©0/1 – system denies any CO calls with 0 or 1 as the first or second digit in the number dialed.
©Area code (three digits) – system denies any calls made by a station whose first three digits are 
toll restricted.
©Area code/office code (six digits) – system denies any calls made by a station whose first six 
digits are toll restricted.
The three- and six-digit toll restriction schemes can be further refined as follows: 
©Any one of four toll restriction levels (eight with DK424 RCTUC/D or RCTUE/F) can be 
assigned. The levels can be defined so that each one is progressively more restrictive by 
enabling or denying specific area or office codes, calls to long distance information, 
international calls, and operator-assisted calls. The levels can be modified using up to eight 
exception tables that enable access to specific office codes within restricted area codes.
©A toll restricted station can still be enabled to dial 411, 911, or 800 numbers if desired.
©Traveling class of service codes can be defined, one for each level of toll restriction. When 
dialed at a toll restricted station, these codes change the level of toll restriction on the station to 
the level enabled by the code for one call. The station then reverts back to its original level of 
toll restriction. The codes can be changed by certain stations that are selected in programming.
©Any toll-restricted station can be assigned the credit card calling feature, which enables a user 
to make a “0+” telephone credit card call from that station.
©Verifiable Account Codes can have a toll restriction class of service. When such an account 
code is entered at a station, the station assumes the toll restriction class of service of the 
account code for that call.
©The Toll Restriction feature can be disabled on a given CO line. For example, toll restriction 
might be disabled on a Tie line, to enable the station to dial extension numbers on the distant 
PBX.
©Restriction levels can also be assigned to verified account codes, which require a user to enter 
an account code before dialing long distance. Individual lines can be defined as unrestricted.
All systems can also be programmed to recognize equal access codes (10XXX and 950-10XX), an 
OCC (Other Common Carrier) DN, authorization codes, and PBX access codes.
On Strata DK systems, any OPS or Tie line can be toll restricted, but it is recommended to use 
LCR for standard single-line telephones.

Toll Restriction Override
There are several ways to override a Toll Restriction level. They are:
©Assign three- to four-digit codes
©Use Centrex feature codes beginning with *
©Assign system Speed Dial numbers
Up to two toll restriction override codes can also be defined. When dialed at a toll restricted 
station, these codes enable the user of the code to override the toll restriction at that station. The 
codes may be changed by certain stations that are selected in programming.
See “Toll Restriction Override Codes” and “Toll Restriction Override Using System Speed Dial” 
for more information.
Benefits
Reduces phone bills because users can make only those toll calls that are necessary for them to 
carry out their job responsibilities.

Toll Restriction Override Codes
Up to two Toll Restriction Override codes can be defined. When dialed at a toll restricted station, 
these codes enable the user to override the toll restriction at that station. The codes may be 
changed by certain stations that are selected in programming.
Up to four (eight on DK424 RCTUC/D and RCTUE/F) service code traveling classes can be 
defined, one for each level of toll restriction. When dialed at a toll restricted station, these codes 
change the level of toll restriction on the station to the level enabled by the code for one call. The 
station then reverts to its original level of toll restriction. The codes may be changed by certain 
stations that are selected in programming.
See the “Toll Restriction” for additional information.
Benefits
Enables authorized users the convenience of overriding toll restriction for more flexible outgoing 
calling.

Toll Restriction Override Using System Speed 
Dial
System Speed Dial numbers can be programmed to override Toll Restriction. When employees 
need to access a toll number restricted by area/office code, an employer can assign that particular 
toll number as a System Speed Dial number.
After overriding Toll Restriction with system Speed Dial, the user can be enabled or blocked from 
dialing additional digits. Dialing long distance provider access codes (10XXX and 101XXX) is 
not allowed, except when using system Speed Dial numbers or LCR.
Benefits
Enables employees to dial specific legitimate business toll calls, without making any other calls to 
that particular area or office code. Preventing unnecessary toll calls can result in cost savings.
Sometimes an Attendant is asked to screen and place calls for toll-restricted users. This feature 
eliminates that extra work, and frees the Attendant to give more attention to incoming calls.

Transfer Privacy
In a system programmed for Transfer Privacy, an outside call that has been transferred can only be 
answered at the station to which the call has been transferred or at another station using the 
Directed Call Pickup feature. No other station can pick up the transferred call using the CO Line 
button.
Privacy features only apply to CO lines and CO line button appearances. The Transfer Privacy 
feature does not apply to multiple DN appearances. However, if Transfer Privacy is enabled, a call 
that is blind-transferred to a multiple appearing DN of a CO Line, will only ring on the DN of the 
prime station (of a PDN) or the owner of a PhDN.
The transferred call rings on all stations having the transferred-to DN before the transferring 
station releases (hangs up) the call, but rings on the prime or owner station only after the call is 
released.
Benefits
Enables protection for the confidentiality of outside calls that have been transferred. Callers are 
assured that the only station that can answer the transferred call is the station to which the call has 
been transferred.

Traveling Class of Service
The normal Toll Restriction class of a station can be temporarily changed to another class. Each of 
the four (eight in DK424 RCTUC/D or RCTUE/F) toll restriction classes of service can be 
assigned a four-digit code and given to users.
By entering the code at a station, a user changes the toll restriction class of service on that station 
to the class of service of the code, which remains in effect for the duration of the call. The station 
then reverts to its normal class of service. Any station can be programmed to change these codes 
for security purposes.
The codes do not print on the Station Message Detail Recording (SMDR) call records. However, 
Verified Account Codes, which can also change Toll Restriction Class of Service, print out on 
SMDR reports.
Benefits
Helps organizations manage telephone expenses and enables selected employees with the 
convenience of using any station while maintaining toll restriction control.

T1 Interface
The T1 Interface provides 8, 16, or 24 multiplexed, simultaneous two-way voice channels for cost-
effective connection to high quality, digital CO services. This enables the system to connect to a 
CO, another DK424 system, or other telephone systems.
Each T1 channel can be individually configured for ANI, DNIS, loop and ground start operation, 
DID operation, or Tie line operation. Both Super Frame and Extended Super Frame modes are 
supported. T1 Interface requires the installation of a Telco or customer-provided Channel Service 
Unit.
T1 DID hookswitch flash capability provides hookswitch flash operation on T1 two-way DID, 
ground start, and Tie lines. This improves DID functionality in T1 applications. This feature 
requires the RDTU2 T1 card.
For E&M Tie lines, configured incoming 800, or other services, an answering position or DN must 
be provided to answer and transfer calls, because all calls are routed to one number. This applies 
for AT&T Megacom™ and like services. With multiple DNs, a Megacom call can be answered 
from any phone having the corresponding DN.
Ground start operation must be used with ACD or Auto Attendant. T1 loop start lines do not have 
any disconnect supervision.
Benefits
Provides economic advantages using the high-traffic capacity of 24 multiplexed, simultaneous 
two-way channels. T1 users also benefit from the increased quality of digital transmission. Access 
to the T1 interface is completely transparent to the station users.

Voice Mail Interface 
Any Strata DK system can be configured with a voice mail messaging system. The system can be 
a Toshiba Stratagy, or a customer-supplied voice mail messaging system.
When voice mail is installed with a DK system, each port on the voice mail system requires one 
standard single-line phone port. No external modules are required.
Depending on the voice mail product installed, some or all of the following features may be 
provided. 
©Automated Attendant – Many voice mail systems offer Automated Attendant as part of their 
overall feature package. 
©ANI/DNIS Routing to Voice Mailbox – Routing ANI/DNIS calls directly to a voice mailbox 
can be set for all calls or just calls during a particular system mode (Day, Day2, or Night). This 
feature is available with in-band voice mail integration only, not with SMDI.
©Call Forward to Voice Mailbox – Each user can forward calls directly to a personal mailbox. 
The caller bypasses the usual sequence of voice mail commands and leaves a message after 
hearing a greeting and/or a tone. Also, if someone calls Station A and Station A call forwards 
to Station B, which in turn call forwards to voice mail, the caller is connected to Station A’s 
personal mailbox.
©Message Waiting Indication – When a message is recorded in a user’s mailbox, the voice mail 
system automatically sets a message waiting indication at the station user’s DKT, EKT, or 
single-line telephone with message lamp (DK40i and DK424 systems, only). The indication is 
turned off after the user listens to the message.
©Station Voice Mail Control – Station users can control voice mail equipment from their 
telephone dial pad. DK14 and DK40i stations can control voice mail equipment when not 
connected in a conference call. DK424 stations can control voice mail equipment on normal or 
conference calls with other stations and outside parties. Users with 2000-series digital 
telephones can also send continuous DTMF tones.
©In-band Voice Mail Integration – The integration of special voice mail features in system 
software enables the Strata DK and Toshiba Voice Processing systems to work together 
efficiently using in-band DTMF signaling tones. This is standard on the DK14, DK40i, and 
DK424 systems. Many other manufacturers’ voice mail systems also support in-band 
signaling integration with DK14, DK40i, and DK424 systems.

SMDI Voice Mail Integration
SMDI voice mail integration is available for use with Stratagy or non-Toshiba voice mail systems 
and can provide more efficient voice mail integration than in-band DTMF signaling when used in 
high volume applications. It requires fewer DTMF receivers and sends information quicker, 
because the voice mail machine processes digital RS-232 data faster that DTMF tones. 
SMDI integrates Strata DK with Stratagy and other voice mail systems, through a digital RS-232 
connection on a WSIU, TSIU, PIOU, PIOUS, RSSU, or RSIU using standard central office 
protocol, providing more universal compatibility with Stratagy or non-Toshiba voice mail systems.
SMDI provides all the integration features of in-band DTMF signaling, except it does not support 
the equivalent of A-tone answer supervision, B-tone recall supervision, or D-tone disconnect 
supervision. SMDI can be important in selling Strata with non-Toshiba voice mail systems that 
customers may already have and want to keep to use with their new Strata DK system.
Advantages provided by the Strata DK and the Stratagy SMDI integration are:
©Uses the ports faster and more efficiently. SMDI is a faster and more efficient integration 
compared to DTMF (in-band) integration and is recommended for high-traffic installations.
©Improves call coverage. Stratagy uses the call forwarding status (all calls, no answer, busy, 
etc.) supplied by SMDI to provide better call coverage. Status information enables Stratagy to 
perform custom applications using Stratagy RNA and Busy Chain options.
©Streamlines messaging procedures. SMDI provides calling party extension numbers to 
Stratagy. Users calling Stratagy do not have to enter their user ID to log onto their mailboxes. 
When an internal party calls an extension that is forwarded to voice mail, SMDI applies the 
calling party identification to the message. Caller ID and ANI numbers are delivered to the 
voice mail machine using SMDI packets. DNIS names are not sent on SMDI packets.
Table 10 is a comparison of the feature integration provided by in-band DTMF signaling and 
SMDI.

Benefits
The customer can gain the benefits of using a voice mail system, because it can easily be attached 
to a Strata system. DK systems are compatible with all Toshiba Stratagy systems and many 
different brands of voice mail systems.
Callers can leave detailed messages for a specific employee and feel their needs are being 
addressed immediately, rather than neglected until the employee calls back. This uses your 
employees’ time more efficiently and enables them to provide your customers better service.
