IntegrationAdd/Change a Trigger Rule
When adding or changing a rule, Filters and Conditions fields display on the Add/Change Trigger 
Rule screen (see Figure 13-6):
Figure 13-6 Add/Change Trigger Rule
Filters
When the triggering event occurs, it may need to pass specific filters or conditions before the 
Action is performed. The Filters (see Figure 13-6) are:
©Caller ID – required/not required. If there is no Caller ID associated with a call, you may not 
want to have an Action performed. The most common example is “Screen Pop” where you 
may select “any Number” to not perform the action until a Caller ID number has been 
received. To trigger an event anytime a call rings, regardless of whether Caller ID is present, 
you need select “none Required.”
©Trigger Delay – a short delay, expressed in tenths of a second, that will occur prior to the 
action. The delay is needed to allow the Caller ID or other information to be received prior to 
performing the action.
©Appearance – the Trigger can be used on any line or a specific line. If the same Trigger 
applies to some lines but not to others, the rule must be entered for each line to which the rule 
applies. Buttons having the same name need only one rule, e.g., two buttons labeled 205 would 
have the same action whenever either ring when a Trigger Rule for Call Ringing is created for 
appearance 205.
Conditions
Conditions (i.e., Phone State, shown in Figure 13-6) include performing the action “if not talking” 
or “if trunk number is available.” You may not want to have an Action performed while you are 
talking on a call. Again, a common example is to screen pop only “If Not Talking”. This prevents 
an Action from occurring until you are finished with the call or placed it on hold.

Actions and Parameters
Actions are set up by the installer to perform a specific function (e.g., Screen Pop Goldmine, Pop 
Telemagic, or Beep My Pager). These Actions can then be used as part of a Trigger Rule and 
performed when a specific event occurs. The existing Actions can be displayed (Figure 13-7), 
edited, deleted or new Actions added.
Figure 13-7 Add/Change Actions
Important!Deleting or adding Actions without instructions from Toshiba or knowledge of your 
program’s DDE commands is not recommended. Toshiba supports editing actions 
that are based on Application Notes.
Add/Edit Action
When adding or editing an Action, the following fields are displayed (see Figure 13-8 and the

IntegrationAction Name – Every event Action has a “Name” that you should set to describe the result the 
action, such as “Beep My Pager.” This name is used in the Trigger Rules.
Ty p e – Select the Action to be performed from the pull-down menu. Each Action has one or more 
parameters that must be provided by the user/installer. These parameters often contain “tokens” 
that enable the inclusion of real-time information (e.g., Caller Phone Number, Date, Time, etc.). 
The choices are as follows:
©DDE Execute – Sends a specific DDE command to the program you specify. This Action is 
very flexible and can be used to communicate with many different types of programs for a 
variety of purposes (e.g., Screen Pop). DDE Execute String parameters include:
©App Name – Used to set the DDE name of the application to receive the DDE event.
©App Topic – Used to set the DDE “Topic” for the application to receive the DDE event.
©DDE Execute String – This is the command executed by the application receiving this 
DDE event. Typically this command includes token(s) so that real-time information is 
included in the command string.
©Show/Hide Test Params Button – When you set up an Action, it is always a good idea to 
make sure the Action works correctly. The Show Test Params button exposes a set of 
parameters (e.g., Calling Phone Number and Calling Name) that can be changed for verifying 
the action defined. 
äTo execute the command, press the Do Test button.
The results of the action are displayed on the lower part of the window. Clicking on the open 
part of the window clears the test results and the process repeated. 
Some parameters contain token(s) that enable the inclusion of real-time information (like the 
Caller Phone Number, Date, Time, etc.). The Tokens are described in Ta b l e  1 3 - 9.

TeleMagic Link
The TeleMagic program (from Telemagic, Inc.) communicates with StrataLink via a special link 
called TeleMagic. The TeleMagic Link appears automatically each time StrataLink is accessed and 
provides a means to set up and monitor communication between the two programs.
Important!For this link to operate, the TeleMagic program must be loaded and operational. 
If you select Auto Activate Link (see Figure 13-10), StrataLink automatically attempts to establish 
the  TeleMagic link periodically (every 30 seconds or so) until the connection is made. Once the 
link is established, the Link Active light changes from Red to Green, dialing and Screen-Pop can 
function. For Screen-Pop to work, the appropriate Trigger Rules must be set up.
Figure 13-10 Telemagic Link
Pop TeleMagic
This instruction sends a “Pop” or “LookUp” command to TeleMagic with the configuration you 
specify. This is used to Screen-Pop the TeleMagic contact manager when a call rings in. Pop 
TeleMagic parameters are:
©Index Level – Tells TeleMagic the level on which to perform the search (e.g., 1, 2, 3, etc.). 
Leaving this parameter blank causes the search to occur on the level in present use.
©Index Name – Selects the TeleMagic index to be used for the search. For Screen Pop this is 
typically “TelePhone #”, but since the Indexes within TeleMagic are programmable, this could 
be set to any appropriate index. The TeleMagic Link must be operational before you can make 
this selection.
©Search String  – This should be set to whatever string should be searched for using the above 
two parameters. For Screen Pop, this is typically the Calling Phone number which would be 
the token &P.
Testing TSPI Link
The TAPI dialog box provides a method for verifying the TAPI Driver is setup and operational. To 
check the driver, select an appearance (e.g., Intercom) and click on each of the Pickup, Dial, and 
Hangup keys individually. To complete the test, you should repeat this procedure for each line 
appearance.
To access the setup screen for the Toshiba TAPI Service Provider, click on the Driver Setup button. 
The Configure Keys section of the screen should be programmed properly as they will be

ISDN Interfaces
ISDN Interfaces14
This chapter covers information on the ISDN Primary Rate Interface (PRI) and Basic Rate 
Interfaces (BRI).
PRI and BRI Overview
©PRI is available on DK424 Release 4.0 systems with RCTUBA3/BB4, C3/D4, and E3/F4 
processors; but unavailable for any other Strata DK systems or processors.
For PRI services, the Strata DK424 uses an RPTU PCB to connect to a Public Switched 
Telephone Network (PSTN) PRI line using a UL listed Channel Service Unit (CSU) in most 
locations in the U.S. Each RPTU provides 23B + D channels. The B-channels support CO 
speech and data connections on the PSTN side only. The RPTU PCB is shown in Figure 14-2 
on Page 14-6. 
©BRI S/T is available for DK40i and all DK424 Release 4.1 processors including RCTUA4, but 
not for any other DK systems.
For BRI S/T services, the DK424 uses an RBSU PCB; the DK40i uses TBSU and RBSU. Both 
the RBSU and TBSU provide two BRI S/T circuits to connect to the PSTN BRI line using an 
external UL listed NT1; or, on the station-side, connect to:
©S-type ISDN telephones and Terminal Equipment (TE-1-S)
©S-type Terminal Adapters (TA-S) with non-ISDN devices
Each TE-1-S and TA1-S device can support voice and/or RS-232 switched-circuit data as 
shown in Figure 14-1. The station-side BRI S/T circuits are point-to-multipoint.
A subassembly (RBSS) can be attached to the RBSU for two additional BRIs for S-type 
station-side connections only. The RBSU PCB and the RBSS subassembly are shown in 
Figures 14-14 and 14-15 on Page 14-21. The combination of RBSU and RBSS uses only one 
slot to provide up to four BRI S/T circuits.
NoteIn DK424, each installed RBSU or RBSS circuit provides a 2B + D connection and uses a 
system capacity of two station ports and two CO lines regardless of the circuit application, 
even if the circuit is not actually connected. In the DK40i, each TBSU, RBSU, or RBSS 
circuit uses two CO lines (no station ports) when configured for the CO side and two 
station ports (no CO lines) when configured for the station side.
©BRI U will be available on all Release 4.2 processors for the DK424, including RCTUA4, as 
well as the DK40i. 
						

							ISDN Interfaces
PRI and BRI Overview
14-2Strata DK I&M 5/99
For BRI U services, the Strata DK424 uses an RBUU PCB. The RBUU provides two BRI U 
circuits that connect directly to PSTN BRI lines; or, on the station side, connect to:
©U-type ISDN telephones and Terminal Equipment (TE-1-U)
©U-type Terminal Adapters (TA-U) with non-ISDN devices
Each TE-1-U and TA-U device can support voice and/or RS-232 switched-circuit data 
depending on the device (see Figure 14-1). The station-side BRI U circuits are point-to-point.
A subassembly (RBUS) can be attached to the RBUU for two additional BRIs for PSTN and/
or U-type station connections. The RBUU PCB and the RBUS subassemblies are shown in 
Figure 14-28 on Page 14-33 and Figure 14-29 on Page 14-34. The combination of RBUU and 
RBUS uses only one slot to provide up to four U-type BRI circuits. 
NoteEach installed RBUU or RBUS circuit provides a 2B + D connection and uses a system 
capacity of two station ports and two CO lines regardless of the circuit application, even if 
the circuit is not actually connected.

ISDN Interfaces
RPTU Interface Unit
System:DK424 Release 4.0
Circuits per PCB:24 channels
Interfaces with:ISDN PRI
Older Version(s):none
The DK424 Release 4.0 system supports the RPTU according to the common control units resident 
in the system.
NoteThe RPTU cannot be installed in a system operating with the RCTUA4.
The RPTU requires installation of a customer-provided CSU in most locations of the U.S. Refer to 
“CSU Requirements” on Page 14-3 for CSU installation.
Testing procedures (local and remote loop back) are in “Loop-back Testing” on Page 14-10.
The RPTU’s LEDs indicate a continuous status of its operation. They are shown in Figure 14-3. 
Table 14-5 on Page 14-7 lists the functions for each LED.
Switches, jumpers, and interface connectors are described in Figure 14-2.
RPTU Overview
The RPTU is a DS-1 divided into 24 TDM channels using standard T1 electrical signal format. 
The RPTU’s D-channel is typically the 24th channel and can control the signaling of 23 of its own 
B-channels and 24 B-channels of another designated RPTU. Each RPTU can also use its own 
D-channel for control.
The RPTU’s in-service bit rate is 1.544 mbps (± 4.6 ppm), but during a maintenance session, the 
rate may vary ± 32 ppm. The RPTU provides Binary 8-Zero Substitution (B8ZS) and ESF with 
Framing Pattern Sequence (FPS) and Cyclical Redundancy Check (CRC) error checking in the 
framing bits.
NoteThe Embedded Operations Channel (EOC) which carries alarm notifications, statistics, 
and error indications is not available with DK Release 4.0 software.
Extracting the Stratum-1 clock from the ISDN PRI, BRI, or T1 provider is the most common 
method used to synchronize the RPTU PCB and the DK time switch to the public telephone 
network. One RPTU, RBSU, RBUU, or RDTU T1 must extract the clock from the ISDN or T1 
provider. The selected unit is designated as the “Primary” timing source in system Program *41-1. 
For more information, refer to “Timing and Synchronization” on Page 14-11.
A dealer-supplied CSU must be installed between the ISDN PRI network line and the RPTU PCB 
as shown in Figure 14-1. Some telephone companies supply the CSU and call it the Network 
Interface Unit (NIU).
CSU Requirements
In the U.S., the CSU must be UL listed and comply with Part 68 of the FCC rules. It must also 
comply with the limits for a Class A digital device, pursuant to Part 15 of FCC Rules. In Canada, 
the CSU must be CSA certified. 
						

							ISDN Interfaces
RPTU Interface Unit
14-4Strata DK I&M 5/99
The CSU is transparent to data, clock, and framing. It acts as a repeater, not a controller, for 
timing. The CSU also acts as a signal regenerator and must be able to perform loop-back tests and 
maintenance to both the network and DK RPTU. The CSU is the same type as used for T1 circuits 
although it performs the function as NT1 for PRI ISDN in the ISDN reference model as shown in 
Figure 14-1.
Slot Assignments
Up to eight RPTU PCBs can be installed in a DK424 system providing up to 188 PRI lines 
(B-channels). If RPTU (PRI) and RDTU (T1) PCBs are installed in the same DK424, the 
maximum combined PCBs cannot exceed the numbers provided in Table 14-1. The PCBs must be 
placed in designated slots in each of the DK424 cabinets per Tables 14-2 and 14-3. The next 
highest slot adjacent to the RPTU slot must be vacant.
Program 03, code 79 designates which cabinet slots contain RPTU PCBs. The maximum number 
of cards and lines is listed in Table 14-3.
