Paging - Group Paging
Any number of digital/electronic telephones can be divided into paging groups and one station can 
be in up to four. A unique access code is assigned to each paging group, that enables voice paging 
exclusively to that group. Any station user can make an announcement to just one or all of these 
groups (All Call Page) that is sent to the speaker of all idle telephones in the page group. The DK 
systems support:
©DK14 – up to five paging groups
©DK40i – up to five paging groups
©DK424 (RCTUC/D and RCTUE/F – up to nine paging groups in systems
©DK424 (RCTUA or RCTUBA/BB) – up to five paging groups
Notes
lThe Cordless DKT-2004-CT or standard telephone is not compatible with paging.
lIf one group is being paged, the Group Paging feature is not available to any other group until 
the first group page is completed.
Benefit
Enhances office efficiency by providing a quick way to contact a group of people without 
disrupting other workers who do not need to hear the message. When all groups are paged, 
everyone can hear the announcement simultaneously.

Pooled CO Lines
A “CO line group” and a “CO line pool” are the same except a pool of CO lines can appear under 
one CO line button on a telephone. CO lines can be pooled in categories. For example, all WATS 
lines of the same type can be in one pool, all regular CO lines in another, and all Tie lines to the 
same destination in a third. Pooled and single-appearing line buttons are designed for use with 
loop- and ground-start lines, not DID, Tie, DNIS, or ANI lines.
The number of CO line groups available on Strata DK systems are as follows:
©DK14 – 4
©DK40i – 8
©DK424 with RCTUA or RCTUBA/BB – 8
©DK424 with RCTUC/D or RCTUE/F – 16
Each CO line pooled group can appear on up to four Pooled Line Grp (group) buttons on a digital 
telephone. This enables the user to process several calls in that CO line group at the same time. If a 
station user regularly processes more than one call at a time, Toshiba recommends that the station 
be assigned more than one Pooled Line Grp button.
It is also recommended to separate incoming and outgoing CO lines into separate groups. This 
prevents the accidental pickup of incoming calls when making outgoing calls.
Benefits
Provides the use of less expensive 10-button telephones instead of 20-button telephones for access 
to the same number of CO lines.
The Pooled Line Grp button also offers “hybrid” type system operation, even while configured for 
“key” operation. This also enables the Strata DK to compete more cost effectively against hybrids.

Power Failure Transfer
Power Failure Transfer automatically switches CO lines directly to a standard single-line 
telephone and provides emergency service if commercial AC power fails. When AC power is 
restored, the system automatically switches back, and the standard power failure transfer telephone 
becomes inoperative again.
The DK14 and DK40i have one power failure transfer port as standard equipment. The DK424 
required one port (DPFT) and transfers up to eight CO lines to dedicated, customer-provided 
single-line telephones.
The DPFT requires one port on an RSTU or RDSU, and only one DPFT can be supported per 
RSTU or RDSU. The DPFT 24V control connects only to an RSTU or RDSU. Multiple DPFTs can 
be attached depending upon the number of power failure transfer CO line circuits required.
During a power failure, the following connections are made:
©DK14 – one CO line is connected directly to the PF phone.
©DK40i – one CO line in the base KSU in connected directly to the PF phone. Up to eight more 
can be added in the expansion cabinet using a DPFT and RSTU.
©DK424 – multiple CO lines can be switched. If AC power is lost, the PF telephone is 
automatically and directly connected to the first CO line.
Benefits
Enables making and receiving calls without interruption of service.

Privacy/Non-privacy Option
The system can be programmed as private or non-private. When the system is in the private mode, 
a station user who makes a call on a CO line or intercom has exclusive use of that line. Other 
stations cannot enter the line by pressing the Line button. When the system is in the non-private 
mode, other stations can enter the conversation by pressing the CO Line button.
This feature applies to CO line buttons only and does not apply to DNs. Outside CO lines can be 
private or non-private on a station-by-station basis. Private lines prohibit users from pressing a 
common CO line button and accessing a line that is already in use, whereas users can do so on 
non-private lines.
Private line users can change the mode by pressing the Privacy Release button enabling as many as 
three stations (total) on a line. Non-private users can block access to their lines by pressing the 
Privacy button.
Benefits
Greater flexibility because the system can be customized to meet the business’ needs.

Relay Service
The standard relay can be programmed for one of three options:
©External Page: A page over external speakers mutes Background Music (BGM) that is being 
broadcast over the same speakers.
©Night Relay: An answering machine or a night bell (or chime) are activated when a call rings 
in during Night mode.
©Hold Relay: A Music-on-Hold source turns on when a call is placed on hold, and goes off 
when the caller is taken off hold. With the relay installed, the music source does not have to 
play continuously.
On DK40i or DK424 systems, two relays are provided using a PIOU, PIOUS, or PEPU option 
card. In addition to External Page, Night Relay, or Hold Relay, these optional relays can also be 
programmed for Door Lock Control, which opens a customer-supplied door lock for three or six 
seconds when a designated button is pressed on selected telephones. See “Door Lock Control” for 
more information.
If a system has BGM on an external paging system, the external page relay makes it possible to 
suppress the BGM when a voice announcement is made over the paging system. Voice 
announcements can be heard clearly without interference from the BGM.
Benefits
Increases options for handling calls when the system is in night service. The customer can choose 
the best arrangement that meets the needs of their business.

Remote Administration/Maintenance 
Remote Administration/Maintenance enables administrative and diagnostic software programs to 
be run “live,” without interruption of normal system operation from a remote location. The IMDU 
modem can operate at 300 or 1200 baud full duplex. DK424 can use the RSIU card with the 
RMDS modem at up to 2400 baud or an external modem at up to 9600 bps.
The Remote Administration module requires two programmable security codes for access to all 
programs (Level 1) or station class of service programs only (Level 2). There are six operating 
modes:
©Programming mode – all programs
©Data dump mode – all programs
©Test CO lines/stations
©LCD messaging – edit and set completely new messages for any DKT (system and personal 
messages)
©Speed dial edit/change
©DKAdmin for backup/restore and program administration (see DKAdmin description in 
System Overview section for details)
In order for the Remote Administration module to work, one CO/Centrex/PBX line must be 
connected to the system. However, this line does not have to be dedicated to the module. If the CO 
line is dedicated it can be programmed to ring the module directly during any ringing mode (Day, 
Day 2, or Night).
If automatic connection is not programmed, connection between a CO line and the module is 
accomplished using the Call Transfer feature. Remote administration/maintenance can also be 
accessed through Auto Attendant, Direct Inward System Access (DISA), and/or DID lines.
Benefits
Reduced service costs because routine service and administrative procedures can be done from the 
service company’s office. Service time is also reduced.

Reserve Power Battery Backup Interface
On the DK14, an optional battery backup unit is available for the system power supply. The 
backup unit (HPFB-6) includes the battery pack and built-in charger and mounts externally. Either 
one or two HPFB-6s can be connected. If other types of batteries are used with DK14, they are not 
charged by the DK14 power supply.
Customer-supplied 12-volt batteries can be connected to the DK40i or DK424 systems as a power 
failure backup system. Batteries are connected to the system’s standard power supply by an 
optional connector cable. The DK40i and DK424 power supplies provide a built-in battery 
charger. Gel-cell maintenance free batteries are recommended.
In the event of a power failure, the system automatically switches to battery power without 
interruption. All functions of the Strata system continue to operate for several hours after a loss of 
normal electrical power. The exact time period depends on the type and size of batteries used, 
system capacity, and traffic (see the Strata DK General Description for details). No calls are 
disconnected during the switch to battery power.
During normal power conditions, the batteries are kept fully charged by the system power supply.
Benefits
Ensures that telephone service is not interrupted by a power failure.

Speed Dial (SD)
Also known as automatic dialing or one-button dialing, this feature enables the customer to assign 
dialing codes to telephone numbers that are frequently called. Each system SD number can have 
up to 20 digits. Two or more speed numbers can also be “chained” during one call to accommodate 
numbers that have more than 20 digits. Pauses and flashes can be programmed into the number. 
Both system and station SD numbers are available.
System Speed Dial (SSD) numbers are available to all station users. A designated station, 
Attendant console, or DKAdmin PC can assign the SD numbers.
The maximum number of available SD numbers is:
©DK14 – up to 40
©DK40i – up to 40
©DK424
©RCTUA processor – up to 40
©RCTUBA/BB processor – up to 100
©RCTUC/D processor – up to 100
©RCTUE/F processor – up to 800
Access to the SD numbers can be assigned on a station-by-station basis, and some stations can be 
restricted. If a station user is restricted from using the SD numbers, that user is automatically 
restricted from having station speed numbers. The SD numbers can also be programmed to 
override toll restriction.
If the system is installed behind a Centrex or a PBX, the SD locations can also be used for storage 
of Centrex/PBX feature access codes. Those codes can then be assigned to appear as automatic 
dialing buttons on phones that need them. In this way, Centrex or PBX feature codes can be 
programmed for one-button access.
SSD codes 90~99 can be pre-defined and incorporated into any other SD code to dial up to 20 
digits (37 digits chained) using one code. For example, an Other Common Carrier (OCC) access 
number could be programmed as SD code 90. Then, SD code 90 could be used as part of the 
telephone number for another SD code by entering *90 as the first three digits in the telephone 
number for that SD code.
Station SD enables the station user to have a private automatic dialing list. Each station can have 
up to 40 station SD numbers. The numbers in this list can be changed by the station user at will. 
Station SD can be enabled or denied on a station-by-station basis.
The station user assigns a two-digit code to each of the telephone numbers, and programs a 
number for each code. The user can then “speed dial” the number by using the code, instead of 
having to dial the number manually. If the station has buttons assigned as SD buttons, one speed 
dial number can be programmed for each SD. Numbers not assigned to SD must be accessed with 
a SD code.

Strata DK Feature Description 5/9995
If SSD codes 60~90 or 600~699 have been pre-defined, they can be incorporated into a station SD 
code to dial up to 37 digits automatically using one code. For example, an OCC access number 
could be programmed as system SD code 90. Then, system SD code 90 could be used as part of the 
telephone number for a station SD code by entering *90 as the first three digits in the telephone 
number for that station SD code.
If the user has a 20-button LCD telephone with the SD memo feature, a 12-character name can be 
programmed for each of the 40 personal SD numbers. The LCD user can then scroll through the 
“memo pad” of names and numbers. When the desired name and number appears on the LCD, the 
user can press a CO line to automatically dial the number.
Benefits
Looking up telephone numbers can be time consuming. Errors can be made in dialing which also 
waste time and can be costly. By using automatic dialing for numbers that are frequently called, 
those time-wasters are eliminated.
Sometimes certain employees need to make business toll calls. However, it may also be desirable 
to toll restrict those employees, yet enable them to dial specific business toll calls using system 
speed dial numbers. This eliminates the possibility of telephone abuse and can reduce costs.
Station Speed Dial enables the Strata DK system to be customized. Station users can us personal 
Speed Dial for telephone numbers they need which are not on a System Speed Dial list.

Station Hunting
There are three types of station hunting:
©Serial Hunting (SH) – routing of calls to the next station in a hunt group
©Distributed Hunting (DH) – routing of calls to the next hunt group
Serial Hunting
When a called station is busy, the call is routed to the next station in the hunt group. If that station 
is busy, the call is routed to the next station in the hunt group and so on. If a station has Call 
Forward set, the call that is hunting is forwarded and leaves the hunt group. Hunt group routing is 
assigned in the system programming database.
Assignment is flexible, so any station may hunt to any other station. Many stations may be linked 
together in the same chain. The hunt group may be as big as all the stations in the system, or as 
small as two stations.
SH can be used with PhDNs, PDNs, or a combination of these. In the case of tone ringing to 
multiple appearing PDNs, hunting takes place only if none of the multiple appearances of that DN 
are idle. If the call is Voice Announce, then hunting occurs if that PDN’s station is off-hook on any 
DN or CO line. A ground or loop start call hunts from a PDN or PhDN only if it has been assigned 
to ring exclusively at the owner station of that DN.
Data-call serial hunting is different from voice-call serial hunting. Data-call group assignment is 
independent from voice-call hunt groups, but the same hunt group size characteristics as above 
also apply to data-call hunting.
Distributed Hunting
When a call is directed to a DH group, the systems hunts for the next available idle station in 
rotation order and then sends the call there. Calls are more evenly distributed than with SH. If a 
station has DND set, hunting skips to the next idle station.
A maximum of 16 DH groups are provided. Each group has its own unique DN which is like a 
pilot number. Up to 32 stations can be in any one group, and distribution can be in any rotation 
desired. A station can be a member of more than one group. If such is the case, the lower group 
number has priority. For example, a call in group seven’s queue would first ring to station 201 even 
if another call had been in group eight’s queue and had been waiting longer for station 201.
Calls can be routed to DH groups from Caller ID/DNIS/ANI lines, Tie lines, loop or ground start 
lines, stations transferring calls, internal direct calls, DISA calls and calls routed through built-in 
or external Auto Attendant. Calls forwarded from stations, or overflow calls from ACD groups can 
also be routed to a particular DH group (except for Call Forward Fixed). 
DH group member telephones should be equipped with Pooled Line buttons if ground/loop start 
lines ring directly to DH groups. The routed CO line flashes only on the called members Pooled 
Line button.
