1 KX-NS1000 Version1.0 Networking Features

2 Introduction KX-NS1000 provides two methods of private networking; 1. One-Look Networking 2. QSIG Networking (via ISDN and H.323) This part will focus on the new NS1000 feature One-Look Networking. The main benefits of One-look networking are; It looks like one PBX system, even though two or more PBXs are networked together. The system can be expanded easily via a Web based maintenance console. No additional servers are required for call control. The main differences between One-look and QSIG are; For One-look, the Master PBX controls all extensions within the network. In a QSIG network, each PBX controls its own extensions. For QSIG, each PBX needs to be programmed individually. For One-look, almost all settings are made in the master PBX only. QSIG is suitable for connecting the NS1000 to the existing KX-TDE/NCP systems, or when there are 17 or more NS1000s in the network. One-Look is available for up to 16 connected NS1000 systems (Max) Microsoft, Internet Explorer, Outlook, Windows, Windows XP, Windows Vista, and Windows 7 are either registered trademarks or trademarks of Microsoft Corporation in the United States and/or other countries.

4 Chapter 1 One-Look Networking : Overview

5 1-1 One-look Networking Concept It looks like one PBX, even when connected through an IP Network. Conceptual View of One-look Networking Head Office The PBX located at the head office controls all of the extensions. Ext.1001 Ext.1002 Branch Office IP Network Branch Office Ext.1101 Ext.1102 Ext.1201 Ext.1202 All extensions within the One-look Network behave as if they were part of the Main Office, regardless of their actual location. * The network can be easily expanded with simple programming. - up to 1,000 extensions can be configured easily.

6 1-2 One-look Networking Overview (1) Master Unit controls one or more Slave Units (up to 15). Physical Connection of One-look Networking Head Office Master Unit The PBX located at the head office is called the Master Unit. PTSN Branch Office Slave Unit IP Network Branch Office Slave Unit PTSN The PBX located at the branch office is called the Slave Unit. If Slave units are installed in Branch Offices, local calls can be made using local trunks. The Slave units can also support additional extensions and UM features.

7 1-2 One-look Networking Overview (2) Specifications * The maximum number of units within an one-look networking is Master : 1 - Slave : 15 * The maximum number of extensions within an one-look networking is 1, Max. 1,000 extensions / networked system - Max. 640 extensions * / site (unit) * SIP Phone : 640 * IP-PT and IP Softphone : 128 * Extension (Physical Extension Card) : 2 * Network Protocol : NS-Net - NS-Net is a network protocol only used for Panasonic products. * No external (additional) server for network call control is required. - Major competitors need server for 5 or more PBXs.

8 1-3 Master Unit and Slave Unit (1) Master and Slave units are the same physical PBX model. The PBX mode (Master or Slave) is set via system programming (Installation). The key parameters assigned to each unit are; - Master : PBX Type=Master, Own IP address - Slave : PBX Type=Slave, Own IP address, IP address of the master unit The PBX mode (Master or Slave) is indicated by the MASTER LED on the front of the unit. Indicators STATUS BATT ALARM MASTER Master : Green ON Slave : Amber ON

9 1-3 Master Unit and Slave Unit (2) Software Version between the Master unit and the Slave unit. The one-look network should be consist of the PBXs which have the same software version. (The revision may differ.) Maintenance -> System Control -> 1.2 Update Program File Now operating software Software Revision may differ. Software Version must be the same.

10 1-4 Main Features (1) System Expansion with Simple Setup Master Unit Slave Unit One-look Networking 2. Automatically access to the master, and configures itself. 1. Expand New Slave Unit

11 1-4 Main Features (2) Trunk call through Remote Units. An extension user can access trunks connected to remote units. International Call Master Unit PSTN München Local Call Paris PTSN Slave Unit Internal Company Call (Free charge) Total call charges can be reduced. * Long-distance and international call charges can be reduced.

12 1-4 Main Features (3) Simplified Programming Web MC connected to the main unit can set all the settings of the slave units. Web MC Master Unit Slave Unit One-look Networking Slave Unit Web MC * When you configure the UM data on Slave units, etc., you must log in to the corresponding Slave unit directly. You can also log in to the Slave unit directly. However, you can configure only the Slave unit s local data.

15 2-1 IP Capacity Expansion : IP Trunks The overall IP trunk capacity does not increase in proportion to sites. Type Stand Alone One-Look Network N sites (N>=2) Upper Limit Total Number of Trunks x N 600 Trunk (Virtual Trunk Card) H.323 Trunks SIP Trunks Trunk (Physical Trunk Card) x N 480 SIP Trunks example 100ch SIP Provider SIP Provider 100ch One-Look Networking Max. / Networked System ->256ch. Max. / Site -> ch SIP Provider * The maximum number of Sites within an one-look networking is 16.

16 2-2 IP Capacity Expansion : IP Extensions The IP extension capacity does not increase in proportion to sites. Type Stand Alone One-Look Network N sites (N>=2) Upper Limit Total Number of Extensions 640 1,000 1,000 Extension (Virtual Extension Card) 640 1,000 1,000 IP-PT and IP Softphone x N 1,000 SIP Phone 640 1,000 1,000 Extension (Physical Extension Card) 2 2 x N 32 SIP-Extension example 300 Max. / Networked System -> 1, Max. / Site -> 640 One-Look Networking 60 * The maximum number of Sites within an one-look networking is 16.

17 2-3 Site Expansion (1) Bandwidth (1/2) Bandwidth for voice data, call control (signalling), and system control between units must be considered when site planning. Required Bandwidth per Call for Voice : Determined by CODEC and Packet Sending Interval CODEC Required Bandwidth per Call for Signalling Packet Sending Interval 20ms 30ms 40ms 60ms G.711 / G kbps 74.7kbps 72kbps 69.4kbps G.729A 24kbps 18.7kbps 16kbps 13.4kbps Phone Type IP Telephones (except SIP phones) SIP Phone Required Bandwidth 43.0kbps 16.0kbps Required Bandwidth for System Control * In addition to the above, Basic Ethernet frame, VPN headers, Required Bandwidth for System Control, etc., should also be considered.

18 2-3 Site Expansion (2) Bandwidth (2/2) Assessing bandwidth - Example; Master Unit IP Network CODEC : G.711 Packet Interval : 20ms Slave Unit Number of Extensions : 50 Extension Type : SIP Phone Number of Simultaneous Calls : 16 Bandwidth required for Voice data = Number of simultaneous calls x 2 x Required bandwidth for codecs (kbps) = 16 x 2 x 80 = 2560kbps Bandwidth required for Signalling = Number of simultaneous calls x signalling bandwidth per call for SIP phones (kbps) = 16 x 16 = 256kbps Total required bandwidth = Bandwidth required for Voice data (kbps) + Bandwidth required for signalling (kbps) = = 2816kbps * In this example, Basic Ethernet frame, VPN headers, system control data, etc., are not considered.

19 2-3 Site Expansion (3) The Number of Simultaneous Calls To fully assess the total bandwidth required, the number of simultaneous calls must also be considered. A guideline of the number of simultaneous calls based on the general call traffic. Number of Registered Extensions Number of Simultaneous Calls * This chart does NOT show the upper limit of simultaneous calls. * This chart is just an example. Actual number depends on each customer.

51 Chapter 1 System Overview

52 What is a Survivability feature? (1) Redundancy of One-look Network Backup-master Mode - When the Master unit stops working or cannot communicate, one of Slave unit become Backup-master and continue One-look network service. [Master unit : Primary call management PBX] [Backup-master : Secondary call management PBX] Max. one Back-up Master can be assigned. - There is no additional hardware or Activation Key required to use Backup Master feature. Isolated Mode - When the Master and Secondary unit stop working or cannot communicate, a Slave unit become independent system to continue own telephone system. (In this case, a Slave unit have some limitation of feature.) - There is no additional hardware or Activation Key required to use Isolated Mode feature.

53 3 1.1 What is a Survivability feature? (2) Redundancy of IP-phone Automatic Rerouting to Secondary PBX - When the IP-phone can not communicate with the primary registered NS1000, those IP-phone will connect to secondary registered NS1000. [IP-Phone : UT/NT/UDT(SIP-DECT) except IPCS] - This feature can work by each extension settings regardless of whether using the One-look network feature.

54 1.2 Backup-Master 4 NS1000 are connected as One-look network. And Slave 1 is assigned as Backup Master. Master NS failed!! Master [Trouble Example] - Equipment trouble - Power Failure - Cable damage Slave2 Slave1 (Backup Master) Private IP Network (Including VPN) Slave3 1) Master NS failed. NS1000 assigned as Backup-Master start to work like stand by CPU. 2) Slave 2 and 3 switch to connect with Backup-Master NS1000. * All AK information transfer to Back up Master from Master and Temporary AK will be act based on information from Master. Temporary AK valid 10 days from when Back up Master start to act.

55 1.3 Isolated Mode 4 NS1000 are connected as One-look network. Slave2 Isolated mode Master Network failed!! Local Trunks Slave1 (Backup Master) Private IP Network (Including VPN) Slave3 Isolated mode Slave mode Local Trunks When the Master unit and a Slave unit can not communicate each other, a Slave unit will become independent system to continue own telephone system. Isolated Mode. In this mode, some of the features in PBX are limited. * When a network was recovered, it is necessary to return the first system by manual operation. (not automatic)

56 1.4 Automatic re-routing secondary PBX When a IP-phone can not communicate with the primary NS1000, those IP-phone will connect to secondary registered NS1000. (IP-Phone : UT/NT/UDT(SIP-DECT) except IPCS.) LAN Master (Secondary PBX for IP-phone) Private IP Network (Including VPN) Primary NS failed!! Slave1 LAN ) Primary registered NS1000 failed. 2) Connect to Secondary registered PBX when a network is available. When the secondary registered PBX is Master NS1000, Activation key is not required. (If not, it may be necessary to prepare a activation key in the Secondary registered NS1000 for backup.) 3) Registration in advance. IP extension of 213 and 214 are necessary to register at Secondary NS1000 in advance. (Those are the reserved number for backup.)

57 1.5 Case Study Master NS failed!! Master Slave2 Slave1 Backup Master Private IP Network (Including VPN) Slave3 1) Master NS failed. NS assigned as Backup-Master start to work like stand by CPU. 2) Slave 2 and 3 switch to connect with Backup-Master NS. 3) EXT under Master switch to connect with Backup-Master as Secondary PBX. (Automatic rerouting) 4) Also, when the network has failed, the slave 2 and slave 3 will become a independent system (isolated mode).

58 Chapter 2 Backup Master Mode

59 2.1 Change from Master to Backup-master (1) When the Master unit is affected by a system, network or electrical failure, a Slave unit which has been pre-programmed as the Backup Master can take control of the remaining Slave units and PBX services can continue. The Master/Slaves keep synchronization by regular Keep-Alive and Keep-Alive Ack packets. If the flow of these packets to/from the Master is interrupted, the Backup Master and Slave re-registration process starts as shown below; <1>After Keep-Alive Timeout expires, Slave1 restarts as Backup Master. (MASTER LED = Green Flashing) Master failed!! Slave1 (Backup Master) Slave2 Private IP Network (Including VPN) Slave3 <2>After Keep-Alive Timeout expires, Slaves 2&3 restart and register to Backup Master.

60 2.1 Change from Master to Backup-master (2) The Backup Master copies the Master system program periodically to ensure that it is always ready to take over if necessary. Master failed!! When the Master unit is a normal mode, the data is transferred periodically. Slave1 (Backup Master) NB: Data which is held on the SRAM of the Master, is not transferred to the Backup Master. SMDR Error Log EXT setting like Timed Reminder Remote Station Lock Check-In/Out Ready/Not Ready/Clean Up Login/Logout EXT, CO, Verified Code base Charge Total Slave2 Private IP Network (Including VPN) Slave3 The alert message ( ) can be sent from the Backup Master to alert the dealer that the system has entered Backup Master Mode.

61 2.2 Supported features by the Backup Master The following features / resources can be supported by the Backup-Master; Resource Available on Backup Master Note Configuration Data YES Any programming changes made to the Backup Master will not be copied back to the Master when it is brought back into service. SMDR Data YES SMDR data can be obtained from the Backup Master. Data can be merged via PC. Call Log YES Supported by KX-UT series only (Internal Call Log) CA (built-in) NO *1 CA Client needs to change to Backup Master PBX IP Address manually. This is not changed automatically. CA (Server) NO *1 Additional CA Server is required for Backup. CA Client needs to change to Backup Master PBX IP Address manually. This is not changed automatically. IMAP4 YES Need to assign 2 accounts. One on Master and One on Backup Master. Activation Keys YES All activation keys on Master will operate on Backup Master for 10 days. *1. IP address of Master PBX and Back-up PBX are not same. So CTI application cannot work automatically.

62 2.3 Supported devices by the Backup Master The following features / resources can be supported if the Master fails; Device/Resource Survivability Note IP-PTs YES Use Automatic Rerouting to Secondary PBX feature on the IP-PT. IP-Trunk YES IP-Trunk can be switched to Backup Master automatically. (Or ITSP Failover service can be employed) OGM NO OGMs must be manually copied to Backup Master. Legacy Trunk / SLT Legacy-GW NO NO UM Mailbox NO Left message in Built-in VM for Master PBX cannot be transferred to Back-up PBX. UM Group YES Any calls terminating on UM:500(Master) will be automatically diverted to UM:501(Backup Master). FAX Server NO

63 2.4 Programming The following system programming needs to be set in the Master System to allow Backup Master operation 1. Home Screen List View <1> Assign which Slave will be act as Back up Master. <2> Configuration Screen > Slot -> System Property -> Multisite 40s Multisite Keep alive Time-out time is used for Alive check for both Master and Slave. 2. Multisite startup monitoring time is the time used by the Slave to decide if to start with Master/Back up Master or Isolated mode*.

64 Chapter 3 Isolated Mode

65 3.1 Change to Isolated mode If the Network fails, the isolated slave unit(s) can be configured to enter Isolated mode. The isolated Slave unit can provide local services via directly connected Extensions and Trunks. (Via local LAN etc) Master Master Unit system programming is copied to each Slave units every hour. (One - by - One) Slave1 (Backup Master) Slave2 Isolated mode Private IP Network (Including VPN) Slave3 Master and Slaves 1&3 can operate normally. MASTER LED = Red Flashing - AK for IP ch in Master PBX is not transferred to slave PBX. - AK for other such as Cellular Link feature is transferred to slave PBX. It works for 10 days as temporal AK after master PBX stops working. - If extension in slave PBX uses VM mail box in master PBX, VM cannot work. VM in same PBX should be used. * No Additional Activation Keys required.

66 3.2 Programming (1) The following system programming needs to be set in each Slave System to allow Isolated operation. Configuration Screen > Slot -> System Property -> Main Change to Enable (Default = Disable) The alert message ( ) can be sent from the Isolated Slave unit to alert the dealer that the system has entered Backup Master Mode. * This is the only setting to use Isolated mode.

67 3.2 Programming (2) The Slave Unit will not automatically return to Normal mode after the problem has been resolved. The Unit will need to be put back into Normal mode manually. 1. Directly Log-in to the Isolated mode system. 2. In the Home screen, select Slave ICON and right click. 3. Select Normal Mode 4. Confirmation window will appear This site will re-start. OK? 5. The Slave will re-start and start to send Start Ack to Master or Backup Master.

68 3.3 Alert Message Reference The alert message can be sent from the Stand-Alone to alert the dealer that the system has entered Isolated Mode. Subject KX-NS1000 System alarm#2 text [System Name] : KX-NS1000 [MPR-ID] : AAAA-BBBB-CCCC-DDDD [Date] : 11/12/31 [Time] : 23:59:59 [Error Code] : 537 [Sub Code] : [Error Message] : Change into ISOLATED Mode Also, the alert message can be sent from the Backup Master to alert the dealer that the system has entered Backup Master Mode. [Error Message] : Change into Backup Master Mode

69 Chapter 4 Automatic rerouting to Secondary PBX

70 4.1 Change to Secondary PBX IP-PTs and KX-UT Series SIP Phones can be programmed with the IP Address information of two PBX systems (Primary and Secondary). Depending on the status of the Primary PBX system (in-service or out-of-service), the terminal can automatically switch to the Secondary PBX system. LAN Master (Secondary PBX for IP-phone) Private IP Network (Including VPN) Primary NS failed!! Slave1 LAN NB:The Secondary PBX needs sufficient port and Activation keys installed to support the additional terminals. [Example] Unit-1 use 200 IP-phone. / Unit-2 use 300 IP-phone. If the unit2 is failed, the unit1 manage the 500 IP-phone. (Pre-registration and Activation key is required.)

85 4.6 KX-UT Programming (5) The KX-UT terminals can then be registered to the Primary system; System Setting (7) UT Registration; Configuration Screen > Virtual Slot -> Primary PBX -> VUTEXT32 -> Registration 9) Register the UT terminal to the Primary PBX. When the KX-UT Terminal is registered for the first time, the IP Addresses of both the Primary and Secondary PBXs are uploaded to it. If the Primary PBX fails, then the UT can find the Secondary PBX.

86 4.6 KX-UT Programming (6) The KX-UT Keep-Alive parameters are set in the Virtual UT Extension Card Properties. Master PBX Private IP Network (Including VPN) Slave PBX Configuration Screen > Virtual Slot -> VUTEXT32 -> Card Property * [PERIODIC Inform] is the keep alive of UT terminal. For KX-UT Series 1) UT sends PERIDIC Inform packet to NS ) NS1000 reply to UT. 3) If the UT does not receive a reply packet from Primary PBX, then the UT look for Secondary PBX and reboots. NB : NT can not move back to the Primary system if the Primary system is running in Isolated Mode. : UT can be programmed with Primary/Secondary NS1000 in One-look environment only.

87 4.7 Data Migration to Backup-Master NB: It takes a few minutes from Logout for the data from the Master system to be copied to it s own internal CF Card before the data can then be uploaded to the Backup Master system. This means that the Survivability Functions are not available immediately after programming. Two Minutes after Master Logout will be sufficient for the feature to propagate throughout the One-Look network.
