DTMF Signal Time Setting
For Strata DK systems, the Speed Dial and voice mail integration DTMF signal time can be set 
independently at 80 or 160 ms in system programming for CO line dialing and for voice mail auto 
dial digits. The standard setting for CO line dialing is 80 ms. The standard setting for voice mail 
digits is 160 ms.
See also the station feature, “Continuous DTMF Signal Time.”
Benefits
Provides flexibility in meeting both the DTMF requirements of the serving CO and those of a 
voice mail device. As a result, a customer can have faster connection time to the public network 
and still accommodate voice mail systems.

E911 Enhanced Operation 
Strata DK14, DK40i, and DK424 systems support Enhanced 911 (E911) emergency services. This 
feature uses special Centralized Automatic Message Accounting (CAMA) trunks to include the 
Caller’s Emergency Service Identification (CESID) in the 911 call.  The local carrier delivers the 
CESID to the Public Safety Answering Position (PSAP) which uses it to determine the exact 
location (building, floor, office number, etc.) from which the call is originating.
Notes
lEach station in the Strata DK may be programmed with a unique CESID.  In some 
jurisdictions, the CESID must be a valid directory number that the PSAP can call back if 
disconnected.  In many cases, this may require Direct Inward Dialing (DID).
lIn order for the E911 feature to be effective, 911 calls and 9+911 calls must be dialed from a 
digital telephone DN or from a single line telephone. 911 calls originated from the CO Line 
button or the Pooled Line button bypass the adjunct equipment and go directly to the CO 
exactly as dialed.
Enhanced 911 is distinguished from conventional 911 by providing more precise information 
about the location from which the 911 call originates.  A conventional 911 call is identified to the 
PSAP by the listed directory number of the organization providing the multi-line telephone 
systems.  Emergency service workers cannot determine the precise location of the caller with 
conventional 911 and this results in services being misdirected, time wasted, potentially and lives 
lost.  Enhanced 911 provides a unique CESID for each telephone using it to identify the location of 
the caller within a large, multi-floor building, multiple buildings within a campus type 
environment, or from an off-premise station that is terminated at a different address than the main 
telephone system.
The CESID is delivered to the PSAP by the local carrier.  The PSAP then uses the CESID to 
interrogate an Automatic Location Identifier (ALI) database that returns precise location 
information.  Once translated, this information becomes associated with the emergency call and 
can be shared with responding agencies such as police, ambulance, fire, etc.
NoteIn some jurisdictions, the business owner is responsible for maintaining accurate 
information in the ALI database. Since Automatic Set Relocation allows telephones to be 
relocated without the business owners knowledge, you may wish to turn Automatic Set 
Relocation off.
For complete information on E911, please see the National Emergency Number Association’s 
home page at http://www.nena.org.  The “911 Tutorial” at that address is particularly helpful.

System Features
Strata DK Feature Description 5/9949
Strata DK14 and DK40i systems support the E911 feature through a standard telephone port to an 
external, third party system.  The third-party E911 adjunct system provides translation and 
signaling of the correct CESID location information to the 911 PSAP.
The Strata DK424 system supports the E911 enhanced locator service through either external 
adjunct equipment or the CAMA Trunk Interface Unit (RMCS).  The RMCS is a special CO line 
card installed in a card slot.  A system will support up to four trunks.  Excess calls will route as 
standard 911 calls over local trunks. 
The CAMA card solution provides internal notification.  When a 911 call is connected to the 
PSAP, the Strata DK will ring designated stations and attendant consoles and present CESID 
information in the displays.  When a notified station answers the call, a three-way conference is 
established between it, the calling party and the PSAP.  The SMDR port generates two call records: 
one at the beginning of the call and one at its termination.
NoteThe FCC is in the process of defining national standards for E911 compatibility, but there 
is no official due date. At present both legal and technical requirements vary significantly 
by state and readers are advised to contact local emergency service providers and 
telephone companies for detailed requirements.
DK14 and DK40i Operation
Strata DK14 and DK40i systems support E911 operation by forwarding 911 calls and 9+911 calls 
to designated standard ports to interface with external, third-party, translation equipment. The 
systems provide up to two standard telephone ports for this purpose.  The external interface 
connects a standard telephone port to a CAMA trunk and provides multi-frequency (MF) signaling 
and translates the DN from the Strata DK to CESID.
The interface between the third-party adjunct equipment and the E911 tandem CO must use 
special CAMA trunks.  These specialized trunks are ordered through the special ordering desk of 
your local phone company.
DK424 Operation
In addition to the external solution, the Strata DK424 system supports the E911 service through the 
CAMA Trunk Interface Unit (RMCU/RMCS), a special CO line installed in a card slot. The 
CAMA Trunk Interface Unit (RMCU) supports two CAMA Trunk Subassemblies (RCMS) that 
support two CAMA trunks each. Software in the DK424 performs the CESID translation and 
signaling.
Adjunct Equipment Suppliers
Two companies have been identified that supply the E911 adjunct translation systems -Proctor and 
Associates, Redmond, WA (800) 824-9719; and Telident, Inc., Minneapolis, MN (800) 536-4911.
Information regarding the E911 adjunct interface equipment can be found in the Strata DK 
Installation and Maintenance Manual.
Benefits
Enables the Strata DK to conform to most regulatory environments. The agency responding to the 
911 call gets location information that makes it easier for them to find the right location within the 
facility. This provides faster emergency service to those needing it.

External Amplified Speaker 
The External Amplified Speaker (HESB) is a six-inch, three-watt speaker with a three-watt 
amplifier built into a wooden speaker box. It can be used to:
©Amplify the ringing on a digital or electronic telephone.
©Provide a paging amplifier/speaker.
©Create an amplified talk-back speaker arrangement in an area where a telephone is not needed. 
The HESB is installed as a speaker and connected to a door phone unit that is used as the talk-
back microphone.
The number of HESBs that can be installed per system depends on the function of the HESB. Any 
number of HESBs can provide loud ringing bells for electronic or digital telephones. Only one 
HESB can be installed if it is used as a paging or an amplified talk-back speaker.
NoteDigital or electronic telephones, an HHEU2 interface, and an HESC-65A cable are 
required for each phone that has a loud ringing bell. A 2000-series digital telephone that 
has been upgraded with a data interface unit can be upgraded with the HHEU2 options but 
older telephone models cannot.
On DK40i and DK424 systems, the PIOU or PEPU Option Interface Unit is required when an 
HESB is used as a paging/amplifier speaker or an amplified talk-back speaker.
Benefits
Provides several options to make a communications system more efficient. A loud ringing bell can 
improve call handling in noisy areas where non-amplified ringing on a phone may not be heard.
A paging speaker ensures that paging announcements can be clearly heard throughout an area. In 
an area where a DKT is not needed, a talk-back speaker provides a cost-effective communications 
solution.

Flexible Button Assignment
On both 10-button and 20-button telephones, one button is usually assigned to the Intercom/PDN 
function. In some cases, the Automatic Off-hook Selection feature is programmed to select the 
Intercom line, eliminating the need for an Intercom/DN button.
The other buttons can be assigned to a CO/PBX line or to certain features. Some possible 
assignments are:
©CO/PBX Line Button – If the telephone is being used in conjunction with a DSS console, all 
buttons could be used as CO/PBX buttons.
©Pooled Line Button – Enable a group of CO lines to appear under one button. Up to four 
Pooled Line buttons per CO line group can be assigned at each telephone. See “Pooled CO 
Lines” for more information.
Ta b l e  7 lists the features that can be assigned to flexible buttons.
There are several standard keystrip patterns that can be programmed to make button assignments 
easy. Buttons on individual stations can then be changed from the standard keystrip pattern 
selected for that station. Strata DK systems have four keystrip patterns from which to choose (A, 
B, C, and D).

However, on 10-button and 20-button telephones, Flexible Button Assignment enables the 
programmer to define each of the buttons instead of choosing a standard keystrip pattern and then 
changing individual buttons. Any button which is not programmed for a specific feature or CO line 
is automatically assigned per the initialized pattern.
The use of the “Keyprint 2000” PC software package now makes custom keystrips easy to create 
and print.
Benefits
Flexible Button Assignment enables each phone to be customized to the particular needs of the 
station user. The system can be tailored to fit the business communication needs.

Flexible Intercom/DN Numbering
Flexible Intercom/DN Numbering enables a station intercom or DN, including the numbers for the 
Attendant stations, to be any number from one to four digits long. The intercom/DN does not have 
to correspond to the fixed station location number in the Key Service Unit (KSU).
The maximum number of available unique station DNs (PDNs plus PhDNs) are listed below:
©DK14 - up to 20 unique station DNs are allowed
©DK40i - up to 56 unique station DNs are allowed
©DK424 - up to 672 unique station DNs are allowed
Single-digit DNs, such as “0”, can be assigned to Attendant Consoles or Attendant telephones.
Benefits
Enables a consistent numbering plan for and facilitate the efficient use of a business’ 
communications system when the system includes several different types of telephone systems. 
Branch offices which have Strata DK systems can have the same numbering plan as larger offices 
using PBXs.
In the case where a system is being used behind Centrex, intercom numbers/DN can match 
Centrex numbers.
If a Strata DK system is replacing a system that had a three- or four-digit numbering plan, the same 
plan can be used with the new system, eliminating the need for new directories and new extension 
numbers.
Finally, if the Strata DK system is being used with a voice mail system that has three- or four-digit 
mailbox numbers, the extension numbers can match the mailbox numbers.

Flexible Line Ringing Assignment
Each incoming CO/PBX line that appears on a given station can be programmed to either ring or 
not ring at that station. Each CO/PBX line can be programmed to ring at any number of electronic/
digital telephones. Thus, the number of ringing electronic/digital telephones per CO line is limited 
only by system size. In the DK424, a maximum of 120 phones can ring at one time.
Each CO line can be programmed to ring the Auto Attendant, night bell, DISA, remote 
maintenance modem or any station DN in the system. A different ringing assignment can be 
created for each of three ringing modes – Day, Day2 or Night. Also, stations assigned to ring can 
do so with any of the following timing designations.
©Immediate
Stations assigned Immediate timing ring as soon as the line rings into the system.
©Delay 1
If stations with Immediate timing have not answered within 12 seconds (3 rings), stations 
assigned Delay 1 timing also begin ringing. Immediate Ring telephones continue to ring when 
Delay 1 Ring telephones ring.
©Delay 2
If the above stations have not answered within 24 seconds (6 rings), stations assigned Delay 2 
timing also begin ringing. Immediate and Delay 1 Ring telephones continue to ring when 
Delay 2 Ring telephones ring.
A related feature, Night Transfer, enables programming of up to three different CO line ringing 
patterns (Day, Day 2, and Night). The ringing pattern can be controlled by any station programmed 
with a Night Transfer button. In tenant service, there are two Night Transfer buttons on DK14 and 
DK40i systems and four on the DK424.
If a DK system is being used in tenant service, each tenant can separately define and control three 
ringing patterns using the Night Transfer1~4 buttons.
Benefits
Provides the flexibility to define CO ringing arrangements to fit the needs of the business. Calls 
can get to their destination quickly. CO/PBX lines can ring directly to a station or group of stations 
in a specific department, without going through a central Attendant. This reduces the Attendant 
call load and enables better service to callers. Flexible Line Ringing Assignment also enables the 
use of private lines in the system, and is used for tenant service.

Flexible Slot Assignment
The flexible slot architecture on DK424 systems enables almost any combination of CO line and 
station ports. Slots in the KSU can be assigned as station, CO line, or Option Interface slots in a 
variety of custom configurations. All stations, CO lines, and optional printed circuit boards are the 
same size and use the same connector to mount into the backplane of the base or expansion Key 
Service Unit cabinet.
Any printed circuit board can be installed in any slot, with the exceptions of the RCTU common 
control unit, which goes in designated processor slots, and the PDKU or PEKU which must be 
installed in slot 11 if RSIU is not used. If RSIU is used, RSIU must be installed in slot 11, in this 
case a PDKU or PEKU must be installed in slot 12 of the DK424 to enable system programming 
and system administration functions.
Benefits
Increases the variety of line/station combinations, so a customer can have a system that is sized 
and tailored to meet their specific needs.

Ground Start Lines 
Ground start lines provide better trunk supervision for disconnect signaling than loop start lines. 
This is particularly valuable in voice mail, Auto Attendant, and ACD applications. It also greatly 
reduces the possible collision of incoming and outgoing pooled line groups calls.
Individual circuits on the RGLU ground/loop start interface unit or RDTU T1 interface unit can be 
configured individually for loop start or ground start, and for DTMF or dial pulse signaling, thus 
maximizing performance and configuration flexibility on a line-by-line basis.
Benefits
Provides flexibility in choosing the best type of lines for the customer’s application and assists in 
gaining the performance characteristics they require.
