2. Agenda • Topics covered today are • Traditional Vs IP • IP Trunks • IP Extensions • IP Terminals yesoptusbusinesscentre.com.au

3. SV9100 – Traditional TDM Technology SV9100 Fax TRUNK S Analogue Trunk Card Telephone Network STATIONS (extensions) Analogue Station Card PSTN (COTs) Lines Cordless phone ISDN 2 Trunk Card BRA ISDN 2 channel Digital Station Card ISDN PRI Trunk Card DT430 Terminal with LCD ISDN 10,20 or 30 www.yesoptusbusinesscentre.com.au

4. Traditional telephony (before IP) • Users had 2 cables on desk, one for phone and one for computer (LAN cable) • All phones, analogue and digital were wired back to the associated extension PBX card • All PSTN, ISDN trunks were wired directly to a trunk card in the PBX • If the phone or fax had to be moved to another location then a tech had to re-jumper the phone • If a new phone was required and there is no spare slot on the relevant card, then a new card and/or chassis was required • Hence PBX could take up more physical space, hence, associated power increases etc www.yesoptusbusinesscentre.com.au

5. NEC Systems • The great thing about NEC systems is that they support both IP and traditional systems • They can be Hybrid, unlike Cisco that only supports IP • For small businesses upgrading internal networks/systems to support IP can be expensive • However, Selling an IP solution is potentially a great way to increase the value of the sale • Cabling, switches etc www.yesoptusbusinesscentre.com.au

7. SV9100 IP Scenario IP NETWORK (Optus) SIP Trunks One advantage of IP is that only one connection is required between LAN and SV9100 for all 512 extensions, adding IP terminals and trunks is via licence IP Handsets 1 512 www.yesoptusbusinesscentre.com.au

8. Ethernet Networks • Terminologies • Switch • allows the connection of a number of devices to the network, such as: • IP Terminals • IP DECT access points • PC’s • Servers • Known as a Ethernet hub, typically comes in 4,8,16,32,64,128 Ethernet ports sizes • Allows formation of VLANs (virtual LANs) • Allows broadcasting • Separates systems with sensitive data or different data types (eg Voice & Data) • Allows for groups (nodes) to be formed, e.g. sales, accounts • Router • Primary role is to connect networks together and hence moves data between other networks forming WANs • Allows connection to Public networks , such as, IP networks (WWW), Public IP Carrier, private networks www.yesoptusbusinesscentre.com.au

9. Basic components of a Local Area Network - LAN • Simply two or more computers communicating with each other File &Print E-Mail Application SV9100 ADSL/Cable/Fibre Modem/NTU SERVERS IP NETWORK (Optus) Router SWITCH www.yesoptusbusinesscentre.com.au

12. IP – Internet Protocol • Most common suite of internet protocols • Internet Protocol (IP) • Data oriented protocol • Unreliable as based on ‘best effort’ • Transmission control protocol (TCP) • Makes up for IP deficiencies by providing reliable stream-oriented connections that hides IP shortcomings • TCP/IP adds great deal of functionality to IP service • Primary interest is on IP, which is the worlds most popular open-system (non-proprietary) protocol suite (www......) • Unique addressing scheme – e.g. TCP/IP address 203.124.156.34 • Every computer or device on a network has its own unique address • IPV4 • This is the current international standard for IP addresses. • IPV6 • This is the new international standard for IP addresses. • IPv6 addresses are written in eight groups of four hexadecimal digits separated by colons, for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334. • NEC SV9XXX range isIPV6 compliant www.yesoptusbusinesscentre.com.au

14. NEC IP Telephony Benefits • Key driver for converging voice and data networks is “cost savings”!!! • Lower implementation costs • No need for a separate voice and data cabling networks • No need for voice network specialist teams • Reduced operational and management costs • Eg IP telephony moves can be as simple as plugging the your phone into an available LAN port and all the user settings will follow the handset. • Relocation much simpler • Mobile staff connections quick and easy, interstate staff just need to log onto a free IP phone • Less time for Adds, Moves and Changes (MACs) • Reduced Carrier Costs • Calls routed via own private data networks • PBX Infrastructure costs are less • No longer need cards to connect analogue and digital extensions, PSTN lines etc www.yesoptusbusinesscentre.com.au

15. NEC IP Telephony Benefits • Quick and easy scalability • New locations • Growth and downsizing • Ideal for new buildings, cost savings by only providing a single cable Cat5/6/7 • Enhanced services • Enhanced services such as true UM applications (integration of Voicemail and email) will bring productivity gains. • Mobility benefits • Work from home agents • Softphones allow you to work from anywhere there is internet access • ST500 application allows phone to act as a PBX IP extension www.yesoptusbusinesscentre.com.au

16. Converged Networks and VoIP Considerations • Converged network needs to sufficiently handle all traffic types – each could have different behaviours, quality and reliability requirements • “Voice Must be Heard” !!!!! • Voice equipment reliability typically 99.999% as a minimum, many data networks do not have this reliability • Voice Over IP (VOIP) requires: • Reliability of route voice packets with minimum delays (latency) • Limited jitter (variation in time between packets of data) • Without dropping or losing packets • Limited Echo • Acceptable Quality of Service (QoS) is necessary • Bandwidth management necessary • Data compression • Local caching • Prioritisation of data types • Blocking unauthorised traffic etc www.yesoptusbusinesscentre.com.au

17. Converged Networks and VoIP Considerations • Voice and Data Separation methods • For easier fault analysis and Network management etc best to keep both networks separated • Create two totally separated and independent physical data and Voice networks • More expensive • Create VLANs (Virtual LANs) • Is a method of creating logically independent networks within the one physical network • Many businesses set up VLAN’s • Can set up group messages • Set up different networks for sales, technical, marketing etc www.yesoptusbusinesscentre.com.au

18. Converged Networks and VoIP Considerations • Fraudulent activity • Wireless connections and WWW access opens up PBX to increased fraudulent risk • Mobility and SiP Trunks key areas of attack, how to we make it more secure? • Session Boarder Controllers SBC’s • Toll Fraud application • Stronger Passwords • Fault diagnosis • More complexed • PBX, Carrier, data networks and equipment, protocols • Test equipment, • Wireshark traces etc often required • Password policies • Do not use PW for 1234 for access to extn 1234 etc www.yesoptusbusinesscentre.com.au

19. Ethernet Networks and connection of IP terminals & devices • Power over Ethernet (PoE) • Some switches are designed so that they can provide power to the devices that are connected to them, for example, IP terminals • 240Vac Adapters • Industry Standard Protocol used for VoIP is SIP • Session Initiation Protocol • Open systems standard to allow sessions between two or more points • Telephony • Instant messaging • Videoconferencing • Click to Dial • SIP allows for • Determination of user location • Session setup eg ringing • Session management eg transfer and termination of sessions (calls) • User availability www.yesoptusbusinesscentre.com.au

20. IP Telephony Myths • Some common myths • Its Free (data costs) • You must have it for Unified messaging • You must have it for Unified Communications • You must change / upgrade your system to get it. • Not NBN compatible!! • To be compatible a system just needs to support SIP trunks • NEC PBXs support Sip Trunks • Most carriers will also deliver SIP trunks terminating to an ATA / Gateway that can then terminate to the PABX as PSTN / ISDN. • Including SL1100, SL2100, SV8x00, SV9x00 www.yesoptusbusinesscentre.com.au
