Strata DK Feature Description 5/9997
DH member telephones should be equipped with PDNs, not CO Line or Pooled Line buttons for 
DID and Tie lines that directly ring to a DH Group. This is to avoid two buttons flashing on the 
telephone when it is called.
PhDNs cannot be assigned as members of DH groups.
ACD Overflow to DH Group (DK424 only)
ACD calls can overflow to DH groups if there is an idle agent in the DH group, but remain in the 
ACD queue at overflow time if all DH group members are busy.
ACD Agent Ring-No-Answer to DH Group (DK424 only)
ACD calls can route to a DH group during an agent ring-no-answer condition if there is an idle 
agent in the DH group. If all DH group members are busy when an agent ring-no-answer call 
attempts to route to the DH group, the ACD call routes to the ACD CO line normal ringing 
assignments.
However, once a call enters a DH group, it cannot be forwarded or serial hunted out of that group. 
This is to avoid falsely routing calls to personal voice mail boxes. Calls cannot be routed to DH 
groups by SH. Also, calls overflowing from an Attendant Console position or DID intercept calls 
cannot be routed to a DH group.
Calls are distributed to a station’s PDN in the case of internal, DID, or Tie line calls. In the case of 
ground or loop start lines, Pooled Line buttons can be established on a station for separate 
identification of DH calls. In this case, both the Pooled Line LED and a common PhDN LED 
flashes. When answered, the call is resident on the Pooled Line button. Individual PhDNs cannot 
receive DH calls.
If no stations in a DH group are idle, new calls routed to that group are placed in a queue waiting a 
station to become idle. A maximum of 10 calls can be in each group’s queue. Callers in queue hear 
ringback tone until a DH member becomes idle and the call is answered. The 11th caller trying to 
enter the queue receives busy tone.
Benefits
Enhances call handling by providing better service to customers and outside callers, because they 
usually reach someone on the first try who can help them. It can also boost productivity for 
internal callers, since they do not have to hang up and redial another DN if the first party does not 
answer.
DH is very popular in voice mail applications with all voice mail ports in a DH group. This 
provides very efficient use and availability of voice mail ports.

Station Message Detail Recording (SMDR) 
SMDR prints call records of both incoming and outgoing calls or outgoing calls only. Strata DK 
systems can also print a call record of outgoing toll calls only. Calls of less than one or ten seconds 
(programmable option) are not recorded. The basic SMDR printout includes:
©Time and duration of the call
©Time to answer the call
©Stations to which the call was transferred
©Type of call – all calls, outgoing only, and toll
©Station number that made the call
©DN of the destination
©Account codes (if the system has been programmed to include)
©ANI, Caller ID, and DNIS/DID/Tie numbers/names (if the system has been programmed to 
include)
If present, the names take the place of the system Account Codes. A sample of the SMDR output 
for outgoing calls is shown in Figure 5.
SMDR is supported in each system as follows:
©DK14 – requires the WSIU, equipped with an RS-232C connector for attachment to a 
customer-provided printer or recording device. Data output speed can be set at 300 or 1200 
bps. 
©DK40i – requires the TSIU, PIOU or PIOUS, equipped with an ASCII RS-232, 6-wire 
modular connector, compatible with most call accounting devices.
©DK424 – requires the PIOU, PIOUS, RSSU, or RSIU, equipped with an ASCII RS-232 6-wire 
modular connector and compatible with most call accounting devices. 
The DK40i and DK424 also require a PPTC connector that converts a 6-wire, modular connection 
to a 25-pin connection (DB-25) and is available from Toshiba.

Benefits
Save costs because telephone abuse can be pinpointed and corrected and telephone bills are 
properly allocated back to the departments that made the calls.
Further, since account codes are included in the SMDR printout, lawyers, accountants, and others 
who provide hourly professional services can accurately bill clients for telephone time.
SMDR can also help increase productivity for employees such as telemarketers who must learn to 
spend the optimal amount of time on each call.

Station Relocation
There are two types of Station Relocation – moving the physical location of the telephone, or using 
dial codes to relocate telephone set features without physically moving its location. When Station 
Relocation is activated, a telephone can automatically maintain its particular characteristics 
(personal speed dial, flexible keys, feature set, and all DNs) when it is relocated from one modular 
jack to another.
A vacant jack of the same circuit type (DKT, EKT, and SLT) must be available whenever 
relocating a station. You can swap or remove an existing telephone to provide a vacant jack. Only 
one telephone can be relocated at a time. Station Relocation is available system-wide and can be 
turned off and on only by the System Administrator’s station.
NoteThis feature does not work when stations are relocated from a PDKU to a KCDU in the 
DK40i.
Benefits
Makes moving telephones quick and easy. Just unplug the telephone from one jack and plug it into 
another. Saves the expense of having a third party re-program the system to reflect these changes.

System Programming Through Station
Any Strata DK system can be programmed using a 20-button digital LCD telephone in the system. 
On DK424 systems, programming is done from the digital telephone connected to PDKU port 005. 
On DK14 and DK40i systems, programming can be done using any station port.
During programming, the station executing the commands is the only station that loses normal 
functioning. Service to all other stations remains normal.
Benefits
Enables simple moves and changes without purchasing additional terminal equipment. All 
programming can be done with a digital LCD telephone.

Tandem CO Line Connection (Trunk-to-Trunk) 
Also known as Trunk-to-Trunk Connection, this feature connects a user to two CO lines in a 
conference. A DKT that sets up a Tandem CO line connectino must have two CO line appearances 
or the connection must be set up on a DN. After connection, the user can drop out of the 
conversation leaving the two outside parties in an unsupervised conference. The CO lines remain 
connected until one of the parties hangs up. Each CO line in the system can be enabled or denied 
the Tandem CO Line Connection feature. Each system supports:
©DK14 – two connections
©DK40i – four connections (maximum)
©DK424 – ten connections (maximum)
Amplified Conference
If the amplified conference option is installed and the amplifier is available, the Tandem CO Line 
Connection is automatically amplified. A trunk-to-trunk connection (up to 10 at one time) is 
established on each DNIS external network call.
Drop Out
On DK424 Release 3.2 and later versions, Tandem CO Line Connection – With Drop Out enables 
standard telephones and Voice Mail/Auto Attendant ports to set up a conference with two CO lines 
and then drop out of the conference leaving the two CO lines connected. 
The station that sets up the two-line connection can reconnect to the tandem connection by dialing 
a pickup code. If more than one tandem connection is set up by a station, the pickup code 
reconnects that station to the tandem connection that has the lowest CO line number as a priority.
Prior to Release 3.2 software, standard telephones could set up two-line conferences, but they 
could not drop out of the connection. The pickup code function applies only to the station that sets 
up the tandem connection. A station cannot pick up a tandem connection which was set up by 
another station.
Automatic Release from Hold
For loop start lines, Strata systems have an Automatic Release from Hold capability that provides 
automatic disconnect. It recognizes the disconnect signal from the CO. If the CO does not provide 
the disconnect signal (most do), the trunk-to-trunk conference must be monitored and released by 
the station user who set it up. For ground start, DID or Tie lines handling the incoming trunk, 
automatic release is accomplished from disconnect supervision.

Benefits
Enables important incoming calls to be connected to employees who are out of the office, resulting 
in more convenient calling and efficient call handling. Internal callers who set up conference calls 
can drop out of the conference when they no longer need to participate. They can return to 
productive work and use their phone to make and receive other calls.

Tenant Service 
Businesses in the same office building can share a system. One DK14, DK40i, or DK424 (with an 
RCTUA processor) can be shared by two businesses. The DK424 with an RCTUBA/BB, RCTUC/
D, or RCTUE/F processor can have up to four tenants.
Tenants can have separate LCR and Toll Restriction plans, Page Groups/Zones, Night Transfer 
ringing assignments, flexible door phone assignments, and CO line ringing assignments. CO/PBX 
lines for each tenant appear in the correct sequence on telephones, and each tenant can have up to 
two dedicated DSS consoles. Station-to-station calling can be done between the two businesses.
CO lines assigned to Tenants 1 and 2 can activate night ringing over external page. Each tenant has 
its own Night Transfer function and can independently control night ringing using their DSS units. 
Both tenants share a common night bell or a common external page zone for night ringing. With 
DK40i and DK424 systems, if zone paging is installed, the two CO line groups can ring over 
different paging zones at night.
Ringing CO lines assigned to Tenant 1 can be picked up using the Night Transfer1 button, while 
ringing CO lines assigned to Tenant #2 can be picked up using the Night Transfer2 button.
Benefits
Provides sharing of functions, features, and costs of a Strata DK system by two to four small 
companies that do not each require a separate system. They also may be able to reduce costs 
further by sharing a receptionist.
If the businesses are related, a common system enables them to communicate easily with each 
other without the expense of separate systems.
Tenant service enables the businesses to appear as two separate companies. They can have separate 
lines, Attendants, and ringing arrangements. Costs can be easily allocated according to use.

Tie Lines 
Tie lines can be installed on a DK40i or DK424 system to connect it to a PBX or another DK 
system in a private communications network. Tie lines can use all DNIS program assignments. 
Incoming Tie line calls can ring a number of destinations within the DK system.
Incoming Tie lines are enabled with Voice First Calling, and the called station can answer back 
handsfree. Incoming Tie lines cannot originate Off-hook Call Announce to a station at the distant 
end.
On the transferring station’s LCD, Tie Line Transfer Recall displays the destination station number 
and CO line number of a CO line call transferred to a station over a Tie line to another system, 
when the call times out and recalls back to the transferring station. The recall timing is 
programmable to meet each customer’s individual need. This feature enables the answering 
position to answer calls appropriately by knowing the difference between a new incoming call and 
a transferred call recalling to the Attendant.
Analog Tie lines are supported by the E&M Tie Line Unit (REMU), which provides four E&M 
type 1 or 2 signaling Tie lines. The Tie lines can be two-wire or four-wire transmission Tie lines 
and can be immediate or wink start. Digital Tie lines are supported by the T1 Interface Unit 
(RDTU).
A secondary protector is required for each Tie line circuit. An optional DTMF tone receiver PCB 
is required in Tie line operation. Tie lines can be configured as dial pulse (rotary) or DTMF (tone), 
and can be toll restricted.
Benefits
Helps to fix costs when the customer has heavy traffic to specific locations, because Tie lines are 
tariffed at a flat rate per month and are not usage dependent. If Tie lines and toll restriction are 
used together, there can be significant reductions in telephone expense.
Tie lines can also access features or CO lines in the distant PBX or key system providing an 
opportunity to further reduce costs. 
Calls transferred from the answer position are often unanswered by the station to which the call is 
transferred. The Tie Line Transfer Recall feature works with calls transferred over Tie lines just as 
they would within the originating system. This feature enables the answering position to answer 
calls appropriately by knowing the difference between a new incoming call and a transferred call 
recalling to the Attendant. This provides the caller better treatment and service.
