Contents Introduction This document describes the methods of connecting a DECT Server to a DXE system and all features that are available between the DXE and the DECT handsets. There is detailed information on the configuration of the DXE to set up the connection to the DECT Server. The document also gives details of the connections between the DXE and the DECT Server but does not show the configuration of the DECT Server. There are two DECT Servers available, the Varix14 and the larger Varix200. There are two methods of connection between the DXE and the DECT Server, ISDN Basic Rate or Primary Rate. 4

General Integration Points The DXE is connected to the DECT Server via ISDN S0 circuits. The S0 circuits can be either Basic rate or Primary rate ISDN. Basic Rate Connection The Basic rate connection requires either the 4ITSU or 8 ITSU cards installed the in DXE and the SOTAS cards installed in the DECT Server to provide the required quantity of S0 circuits. (Note the Varix14 Server has 2 BRI circuits on the main board). The quantity of S0 circuits is proportional to the number of simultaneous calls required by the DECT handsets, each S0 circuit will allow 2 simultaneous calls. Primary Rate Connection The Primary rate connection requires the ITSU-20P2 card installed in the DXE and the S2MM card installed in the DECT Server. This card will allow 30 simultaneous calls to the DECT handsets. The primary rate connection is only supported with the DXE328 system. The DXE24/32/96 does not support the Primary rate card set as S0 working. DXE Extension and DECT Handset Numbering Plan The numbering plan for both the DXE extensions and DECT handsets should be considered as early as possible. The main reason being that the DECT handset numbers are set by the DXE S0 ports. The extension numbering of the DXE S0 ports can be done in two ways; either the S0 ports can be numbered directly or they can be placed in a Station Group and the group then given a single pilot number. Numbering the S0 Ports Directly The S0 ports are numbered directly with CMD0502 on the DXE. Each S0 circuit has 2 DXE extension ports, each port is given an extension number. The extension number of each S0 port is used as the DECT handset number. This method does not allow the S0 ports to be shared by all of the DECT handsets and also limits the number of DECT handsets to the same quantity of S0 ports. Numbering the Station Group of S0 Ports All the S0 ports that are used for connection to the DECT Server can be placed in a Station Group in CMD1003 on the DXE. The Station Group is then given a pilot number in CMD0506. The pilot number is then used as the leading digits for the DECT handsets. This method allows the S0 ports to be shared by all of the DECT handsets and therefore allows more DECT handsets than the quantity of S0 ports. Since the DECT handset numbers are defined by the pilot number then all the DECT handset numbers must be within one extension number block. The block is in steps of 10, 100, 1000 or 10 000 extension numbers. The set up of the numbering plan is described in detail later in this document. 5

Basic Rate S0 Connection The Basic rate connection is supported on the DXE24, DXE32/96 and DXE328 systems. The Basic rate cards for the DXE24 and DXE32/96 is either the 2BRIU or the 4BRIU. For the DXE328 either the 4ITSU or 8ITSU is used. The Basic rate card for the DECT Server is the SOTAS card or the main board for the Varix14 Connecting the DXE to the DECT Server The connections for the 2/4BRIU card are shown in the following table. RJ45 socket of the 2/4BRIU card Pins 4 5 Connects to screw terminals of the SOTAS card (or main board of the Varix14) OUT terminals a b Pins 3 6 IN terminals a b The connections for the 4/8ITSU card are shown in the following table. 2 way DDK sockets of the 8FU-E1 card Pins 5 6 Connects to screw terminals of the SOTAS card (or main board of the Varix14) OUT terminals a b Pins 7 8 IN terminals a b Settings for the 2/4BRIU and 4/8ITSU cards The T/S mode jumper should be set to S mode. The Termination jumper should be set to ON. The Power Feed jumper should be set to OFF. Refer to the separate manuals for further information on the 2/4BRIU and 4/8ITSU (2BRIU/4BRIU Manual for the DXE24, DXE32 and DXE96 or DX2E-ITSU Manual for DXE328). 6

Programming for the Basic Rate S0 Circuits of the DXE Each Basic rate circuit used for connection to the DECT Server should be set to Point to Point (mode 5 in CMD0307 item 1). You must also enable Nitsuko Specific Protocol (CMD0307 item 4=1) to allow the DECT handsets to access DXE Service Codes. Refer to the separate manuals for further information on programming (2BRIU/4BRIU Manual for the DXE24, DXE32 and DXE96 or DX2E-ITSU Manual for DXE328). 7

Primary Rate S0 Connection The Primary Rate connection is supported on the DXE328 system only. The Primary Rate card for the DXE328 is the ITSU-20P2. The Primary rate card must have Version 1.1 or later firmware. The Primary Rate card for the DECT Server is the S2MM card. Connecting the DXE to the DECT Server The connections for the ITSU-20P2 card are shown in the following table. 2 way DDK sockets of the 4FU-C1 card Connects to screw terminals of the S2MM card Pins 5 6 OUT terminals a b Pins 7 8 IN terminals a b Settings for the ITSU-20P2 card The T/S mode switch should be set to S mode. Programming for the Primary Rate S0 Circuits of the DXE Each Primary Rate circuit used for connection to the DECT Server should be set to Primary Rate S-Point (mode 10 CRC4 OFF or mode 11 CRC4 ON in CMD0307 item 1). You must also enable Nitsuko Specific Protocol (CMD0307 item 4=1) to allow the DECT handsets to access DXE Service Codes. The number of B-channels should be set to 30 (in CMD0307) for a PRI S0 interface. 8

Set Up of the Numbering Plan for the DXE The DECT handset extension numbers are set by the extension number range of the DXE S0 ports used to connect to the DECT Server. The extension numbering of the DXE S0 ports can be done in two ways; either the S0 ports can be numbered directly or they can be placed in a Station Group and the group then given a single pilot number. Numbering the S0 Ports Directly The S0 ports are numbered directly with CMD0502 on the DXE. Each S0 circuit has 2 DXE extension ports, each port is given an extension number. The extension number of each S0 port is used as the DECT handset number. This method does not allow the S0 ports to be shared by all of the DECT handsets and also limits the number of DECT handsets to the same quantity of S0 ports. Numbering the Station Group of S0 Ports All the S0 ports that are used for connection to the DECT Server can be placed in a Station Group in CMD1003 on the DXE. The Station Group is then given a pilot number in CMD0506. The pilot number is then used as the leading digits for the DECT handsets. This method allows the S0 ports to be shared by all of the DECT handsets and therefore allows more DECT handsets than the quantity of S0 ports. Since the DECT handset numbers are defined by the pilot number then all the DECT handset numbers must be within one extension number block, as defined by the pilot number. The block is in steps of 10, 100, 1000 or 10 000 extension numbers. Defining the Pilot Number for a Group of S0 ports The Pilot number for the Station Group is set in CMD0506 on the DXE. The length of the pilot number depends on the length of the numbering plan for the DXE extensions and the range of DECT handset numbers required. The length of the pilot number is calculated as follows. Step 1 How many DECT handset extension numbers are required? The DECT handset numbers must be within one block of extension numbers. The size of the block is in steps of 10, 100, 1000 or 10 000 extension numbers. For example. If handset numbers 300 to 309 are required then the block of extension numbers 300 to 309 must be assigned to the Station Group on the DXE (a block of 10 extension numbers). If handset numbers 300 to 319 are required then the block of extension numbers 300 to 399 must be assigned to the Station Group on the DXE (a block of 100 extension numbers). The following table shows the block size for the quantity of DECT handset numbers. 1-10 Block of 10 Quantity of DECT handset numbers required 11-100 Block of 100 101-1000 Block of 1000 1001-10 000 Block of 10 000 9

Step 2 What is the Extension Number Length of the DXE Extensions In order to maintain the same extension number length for both the DXE extensions and the DECT handsets then the Station Group pilot number set in CMD0506 must allow enough additional digits to support the quantity of DECT handset numbers but not be more digits than the system numbering plan. Step 3 Calculate the Number Length for the Pilot Number The Pilot number must be less digits than the DXE extension numbers to allow for the additional digits that will be added by CMD0307 item 3. The number of digits for the Pilot number is shown in the following table. DXE extension number length 1-10 Block of 10 Quantity of DECT handset numbers required 11-100 Block of 100 101-1000 Block of 1000 1001-10 000 Block of 10 000 Step 3 Number of digits for the Pilot number in CMD0506 2 digit 1 Note 1 Note 1 Note 1 3 digit 2 1 Note 1 Note 1 4 digit 3 2 1 Note 1 Note 1 These settings would result in the DECT handset numbers being more digits that the DXE extension numbers, therefore not maintaining a standard number plan for all extension numbers. 10

Step 4 Setting CMD0307 Item 3, Number of Additional Digits for S0 Ports Finally set the number of additional digits for all S0 circuits used for connection to the DECT Server. CMD0307 item 3 must be set to the number of digits as shown in the following table. DXE extension number length 1-10 Block of 10 Quantity of DECT handset numbers required 11-100 Block of 100 101-1000 Block of 1000 1001-10 000 Block of 10 000 Step 3 Number of digits for the Pilot number in CMD0506 (Note. This is also the setting for the digit length in CMD0501 for the Pilot number dial) 2 digit 1 Note 1 Note 1 Note 1 3 digit 2 1 Note 1 Note 1 4 digit 3 2 1 Note 1 Number of digits for CMD0307 item 3 1 2 3 4 Example of DXE Configuration for Extension Numbering Plan A customer has DXE extension in the range 200 to 250 and requires 15 DECT handsets with handset numbers in the range 301 to 315. From the above tables 15 DECT handset numbers require a block of 100 extension numbers. The DXE extension number length is 3 digits therefore the Pilot number for the Station Group must be 1 digit in length and CMD 0307 item 3 must be set to 2 additional digits. The Pilot number, set in CMD0506, in this example will be 3. The only other DXE programming will be to set the number of digits for extension numbers beginning with dial 3 to 1 digit in CMD0501. 11

Voice Mail Operation (Nitsuko NVM) If the DECT handsets want to forward calls to voice mail then a spare ASTU port will be required for each handset that needs to set forward to voice mail. The ASTU port must not have any telephone connected and should be named appropriately in CMD0502 (eg DECT-VM1) to prevent the port being used at any time after installation. The ASTU port is required because the DXE ports do not support any call forward Service codes (848, 845, 843, 842). So to allow a DECT handset to set call forward the DECT Server is re-configured to support Service codes 848 and 845 as call forward immediate (848) and call forward on no answer (845). The DECT Server is configured to allow each handset to forward to a speed dial location within the DECT Server. The speed dial routes the call to the extension number of one of the spare ASTU ports on the DXE. Then any calls to the DECT handset are forwarded by the DECT Server back to the DXE via another S0 port. Note that each call forwarded back to the DXE will busy out two S0 ports for the duration of the call. To now route the call to the voice mail system the ASTU port must have a call forward immediate set to the voice mail pilot number. The call forward is set at the time of installation by connecting a POT phone and dialling 848+1+VM pilot number. The POT phone is then removed. When the call is answered by the voice mail system the DXE will send ***3SSSXXX where SSS identifies the originating party and XXX is the extension number of the ASTU port. The call will be routed to mail box XXX. Set Up of the NVM Voice Mail To route the call to the mail box of the correct DECT handset the NVM must be set up to route the call to the subscriber mail box for the DECT extension number. This is done by setting the mail box numbers for the spare ASTU ports as Call Routing mail boxes. The Call Routing mail box will define the Dial Action Table (DAT). Within the DAT the time out option is set to REC1 into the mail box number for the DECT handset. The mail box number for the DECT handset is a standard Subscriber mail box with the following settings. Note that you will need two mail boxes on the NVM for each DECT handset that uses call forward to voice mail. Each Subscriber mail box used for a DECT handset must have Message Waiting Lamp disabled, Message Notification enabled, time for dial commands set to 1 and default messages disabled within the mail box options. 12

Message Waiting Indication to the DECT Handset The DXE does not support message waiting indication to an S0 port. To give an indication that a message has been left in the mail box for a DECT handset the NVM is set up to give Message Notification to the DECT handset number. The message notification will also need to be enabled by each DECT handset by calling voice mail and selecting mail box options (67+6) and enabling the appropriate selection set to give notification to the DECT handset number. In order for this to not give false calls to voice mail the DECT handset must set call forward on no answer and the no answer time set on the DECT Server must be longer then the notification time set on the NVM. The DECT Server will only support call forward on no answer to a DXE extension if the forward is set up to another spare extension on the DECT Server. Also, if the DECT handset has an entry in its TelBook for the voice mail port extension number that sets message notification then the DECT handset will display TelBook name when the message notification is performed by the voice mail. Message Retrieval To retrieve messages the DECT handset makes a call to the pilot number of the voice mail system. The voice mail system will request the mail box number and password. Call Barring Call barring is not available at S0 ports of the DXE. If the customer requires call barring this must be done on the DECT Server. Call Logging The DXE does not log outgoing trunk calls against the DECT handset number. All outgoing trunk calls are logged against the S0 ports that are used to connect to the DECT Server. DSS Busy Lamp Indication DSS Console Keys It is possible to have a DSS key for a DECT handset number on the 100 or 24 button DSS console but the key will not show any busy lamp indication. The key is used only to make a call to the DECT handset. Function Key at a Keystation set as DSS Operation (1058) It is not possible to set a function key at a keystation for a DECT handset number when the S0 ports have additional digits set in CMD0307 item 3. The DXE will only allow the number of digits set by CMD0501 to be stored. The DXE will allow the function to be set when the S0 ports are numbered directly in CMD0502 but there will be incorrect busy lamp indication. 13

Ring Group Operation There are various configurations of ring group working, the most common are described below. One DECT handset as part of a DXE Ring Group It is possible to place one of the S0 ports in a ring group in CMD0909 on the DXE. Therefore the number of DXE ring groups that can include a DECT handset is limited by the quantity of S0 ports. When a call is presented to the ring group the DXE will send the extension number set in CMD0502 for the S0 port in the ring group. If CMD 0307 item 3 has any additional digits specified then the DXE will add the appropriate quantity of 0 s on to the S0 port extension number. The DECT Server must be set up to route this number to the appropriate DECT handset. More than one DECT handset as part of a DXE Ring Group This is only possible by the same DXE programming as described for one DECT handset as part of a DXE ring group. The DECT Server then needs to route the call to the appropriate number of DECT handsets. This is possible by routing the call to a hunt group, the call will then step around the hunt group. It is not possible to make all DECT handsets ring simultaneously. The number of separate ring groups is limited by the quantity of S0 ports. DDI to a DXE Extension/Ring Group that Steps on to a DECT Handset This is possible by placing an S0 port in a DXE ring group (as described above) and then entering this ring group in CMD1814/1815. Hunt Group Operation It is not possible to include a DECT handset as part of a DXE Station Group. An S0 port is ignored if it is placed in the Station Group in CMD1003 or a DECT handset number is entered as an additional group member in CMD1035. 14

Features an Facilities Features And Facilities The following features and facilities are in the same order as listed in the DXE DECT Integration on Nitsuko DXE document (NKUK-078). Make an internal call Calls from a DXE extension are made by dialing the DECT handset number. This is routed to a free S0 port and the handset number is passed on to the DECT Server. The DECT Server then routes the call to the handset. Calls from a DECT handset to a DXE extension number are routed by the DECT Server to the S0 ports of the DXE. The DECT Server must be configured to route all DXE extension number and Service code ranges to the DXE. For example extension numbers, station group pilot numbers, voice mail pilot numbers and 7xx plus 8xx for Service codes. Calls from a DECT handset to another DECT handset are routed internally within the DECT Server. This prevents unnecessary usage of the S0 ports. Make an External Call External calls from the DECT handsets are routed by the DECT Server to the S0 ports of the DXE. The DECT Server must be configured to route the trunk access code (eg 9) to the DXE. Transfer a call Calls are transferred by the DECT handset by pressing the R key, dialing the number and pressing the send key. When the R key is pressed the call is held at the DECT Server and will therefore hear music on hold tone from the DECT Server. If an external music on hold source is used by the DXE this can also be used by the DECT Server. This will require an SLT port on the DECT Server set up as a music on hold input. CLI Presentation Incoming ISDN calls routed by the DXE to a DECT handset will show the CLI of the incoming caller (assuming CLI is presented to the DXE from the incoming trunk call). Calls from a DXE extension will also show the DXE extension number at the DECT handset. If the CLI matches a TelBook entry in the handset then the CLI will be replaced with the name associated with the TelBook entry. Note the DECT handsets also show the text Intern for both trunk and DXE extension originated calls. When calls are transferred by a DECT handset to a DXE extension the CLI is not passed on. The DXE extension will indicate that it is talking to the DECT handset for duration of the call. Also, when calls are transferred by a DXE extension to a DECT handset the CLI is not passed on. The DECT handset will indicate that it is talking to the DXE extension for the duration of the call. 15

Features an Facilities Call List The call list will store the CLI for an unanswered trunk call. To allow the DECT handset to return the call both the DECT Server and the DXE must be set up to route digit 0 as a trunk access code. On the DECT Server digit 0 is set up the same as digit 9; to seize an S0 port at the DXE and repeat the digit 0. On the DXE there a two ways that digit 0 can be set up as a trunk access code. Method 1 CMD0501 Digit 0=type 8 This method will not work as the digit 0 will be stripped off by the DXE and therefore will not be dialled to line. Method 2 CMD0501 Digit 0=type 9 (F-Route) This method will work correctly, the only limitation is that digit 0 is not available for Operator access on the DXE. The DXE is set up to translate digit 0 into seize trunk and repeat the digit 0. Call Back / Camp On Call back/camp on is available when a DECT handset calls a busy or ring no answer DXE extension. Call back/camp on is not available when a DXE extension calls a busy or ring no answer DECT handset. Common Speed Dial The DECT Server has to be set up to route Service code 813 to the S0 ports of the DXE. Call Forward The call forward Service code is not supported at a DXE S0 port therefore the DECT Server must be set up to perform the forward. This is done by setting 848 as a call forward Service code on the DECT Server. The call forward is pointed at a speed dial location on the DECT Server, the speed dial location contains the DXE extension number. The speed dial location number and stored DXE extension number are the same so the DECT handset user appears to set call forward directly to the DXE extension number. It is possible to set a call forward from a DXE extension to a DECT handset number. Call forward Service codes 848 (All calls), 843 (Busy), 845 (No answer) and 842 (Dual ring) are available. Service codes 844 (Tandem ring) and 846 (Follow me) are not available from a DXE extension to a DECT handset. Conference To allow a DECT handset to initiate a conference then the DECT Server must be set up with Service code 826 as conference. When the R key is pressed at the DECT handset the call is placed on hold at the DECT Server. The DECT handset user then dials the required number and presses the R key to establish the conference once the called party answers. A DXE extension can initiate a conference with a DECT handset by placing the call on hold and dialing 826 or by pressing a function key set up for conference. 16

Features an Facilities Do Not Disturb (DND) The DECT Server must be set up to with Service code 826 as DND. The DECT Server will then return a busy indication to calls from DXE extensions. The DXE extension will therefore hear DXE busy tone when a call is made to the DECT handset. It is not possible to give DND tone or the VAU announcement to the DXE extension when a DECT handset sets DND. When a DECT handset makes a call to a DXE extension that has DND set the DECT handset user will hear busy tone. It is not possible to give the VAU announcement to the DECT handset when a DXE extension sets DND. Doorphone A doorphone on the DXE can not ring at an S0 port. If a doorphone needs to ring a DECT handset then you must install additional analogue ports in both the DXE and the DECT Server. The DXE will need a spare ASTU port for each doorphone that rings at a DECT handset. The ASTU port is set to ring for the doorphone in CMD1502. The ASTU port is connected to an analogue trunk port at the DECT Server. The DECT Server is then set up to route the analogue trunk to the DECT handset. Since the quantity of analogue trunks that can be supported at the DECT Server are limited only 2 doorphones can be set to ring at a DECT handset. If the doorphone needs to ring at more than one DECT handset then the analogue trunk must be set up to route to a hunt group that will step around the DECT handsets. When the doorphone is ringing at the DECT handset there will be no indication on the display that the call is from a DXE doorphone. The only indication that the call not from a DXE extension/dxe trunk is the display will shoe Extern. Extern will only be displayed when an analogue trunk rings at the DECT handset. Once the doorphone call has been answered by the DECT handset any doorlock associated with the doorphone can be operated by pressing R plus another digit. The DECT Server must be set up to translate R plus digit into a Timed Break Recall on the analogue trunk port. Follow Me The Service code 846 is available at the DXE S0 port. A DECT handset can dial 846 plus 1 followed by the DXE extension number. Calls to the DXE extension will then ring at the DECT handset. The follow me is cancelled by dialling 846 plus 0 followed by the DXE extension number. Key Lock Key lock is available as standard at the DECT handset. Keytel voice/ring A DECT handset can make a call to a DXE extension and change between ringing and voice call by dialling either the one digit Service code (CMD0512 item 3) or dialling the Service code 812 (CMD0511 item 40). This feature will need CMD0307 item 4 (Nitsuko Specific Protocol) enabling. Last Number Redial The last 10 numbers dialled are stored in the redial list of the DECT handset. 17

Features an Facilities Paging (Internal zone) The DECT handset can make a page call over the DXE internal zones by dialling Service code 801 plus the zone number. The DECT Server must be set up to route 801 to the DXE S0 ports. The DECT handset can remain off hook and wait for the paging call to be answered. Paging (External zone) The DECT handset can make a page call over the DXE external zones by dialling Service code 803 plus the zone number. The DECT Server must be set up to route 803 to the DXE S0 ports. The DECT handset can remain off hook and wait for the paging call to be answered. Paging (Answer internal) The DECT handset can answer a paging call that has been made over the DXE s internal paging zone by dialling Service code 864 plus the zone number. The DECT Server must be set up to route 864 to the DXE S0 ports. The DECT handsets can not use Service code 863 (Answer internal page if extension is in same group) as the DECT handsets can not be part of a DXE internal paging zone. Paging (Answer external) The DECT handset can answer a paging call that has been made over the DXE s external paging zone by dialling Service code 865 plus the zone number. The DECT Server must be set up to route 865 to the DXE S0 ports. Personal Speed Dial The DECT handset have a TelBook that can store up to 40 numbers and names. Pick Up (Directed) The DECT handset can pick up a call ringing at a specific DXE extension by dialling 715 plus the DXE extension number. The DECT Server must be set up to route 715 to the DXE S0 ports. A call ringing at a DECT handset can not be picked up either from another DECT handset or a DXE extension. This is because the DXE can only pick up calls ringing on a DXE port. Therefore to pick up the call ringing at a DECT handset you would need to know which one of the DXE S0 ports is being used to ring the DECT handset. Pick Up (Own group) The DECT handset can pick up a call ringing at another DECT handset or DXE extension by dialling Service code 867. The DECT Server must be set up to route 867 to the DXE S0 ports. This feature will require all S0 ports that are used for connection to the DECT Server to be placed in the same pick up group in CMD1012. This pick up group can also have DXE extension ports included if required. When the DECT handset dials the Service code for pick up own group the DXE will pick up the longest ringing call within the group. A DXE extension can also pick up a call ringing at a DECT handset with Service code 867. The DXE extension must be in the same pick up group as the S0 ports that are used to connect to the DECT Server. 18

Features an Facilities Pick Up (Selected group) The DECT handset can pick up a call ringing at another DECT handset or DXE extension by dialling Service code 868 plus the pick up group number. The DECT Server must be set up to route 868 to the DXE S0 ports. This feature will require all S0 ports that are used for connection to the DECT Server to be placed in the same pick up group in CMD1012. When the DECT handset dials the Service code for pick up own group the DXE will pick up the longest ringing call within the group. A DXE extension can also pick up a call ringing at a DECT handset with Service code 868 plus pick up group number. Pick Up (Any group except own) The DECT handset can pick up a call ringing at a DXE extension that is part of another pick up group by dialling Service code 869. The DECT Server must be set up to route 869 to the DXE S0 ports. This feature will require all S0 ports that are used for connection to the DECT Server to be placed in the same pick up group in CMD1012. Therefore, this Service code can not be used to pick up a call ringing at another DECT handset. When the DECT handset dials the Service code for pick up own group the DXE will pick up the longest ringing call within the group. A DXE extension can also pick up a call ringing at a DECT handset with Service code 869. The DXE extension must not be in the same pick up group as the S0 ports that are used to connect to the DECT Server. Pick Up (Park Hold) The DECT handset can pick up a call that has been placed on park hold by a DXE extension by dialling Service code 861 plus the park hold location. The DECT Server must be set up to route 861 to the DXE S0 ports. Transfer Page The DECT handset can press the R key to hold the current call and then make a call over a DXE paging zone. When the paging call is answered the DECT handset can press the send key to transfer the held call.
