Managed IP Converged Telephony Services

1. Managed IP Converged Telephony Services Presented by NNTU DIT Summit 2010 November 17, 2010

2. Presentors: Pearl Lee, Program Manager, NNTU Tim Steiner, NNTU Consultant Victoria Begay, Account Executive, NCC/Frontier

3. Discussion Topics • Navajo Nation Telephone Services • IP Telephony Basics • Navajo Communications Company (Frontier) Managed IP Telephony Contracted Services • Managed IP Telephony Implementation including Network Issues

4. NN Telecommunication and Utilities Department (NNTU) • Responsible for the administration and management of the Navajo Nation governmental office’s telecommunications and utilities services. • Mission is to provide quality and affordable, telecommunication services. • Arranges for 4,800 lines of Centrex telephone service.

5. Overview • NN President has signed a contract with Navajo Communications Company (Frontier) to implement IP Telephony Service • NNTU funded to convert feasible Window Rock sites and others • With savings and additional funding, other sites will be converted

6. 1 0 Internet Protocol IP Telephony Basics • IP packets of digitized data travel over IP-Based mediums (wired & wireless) Analog Digital CODEC or VOCODER Analog to Digital Converter Analog

7. Circuits vs. Packets • Circuit Switching –an establish dedicated circuit (channel) connection between end nodes so that users may communicate. • Dedicated circuits cannot be used for other users until the circuit is released and a new connection is set up, even if no actual communication is taking place • USED BY CURRENT CENTREX • Packet Switching - Internet technology • Does not require a circuit to be established and allows many pairs of voice, data and video sites to communicate almost simultaneously over the same channel • USED BY VoIP

8. Stand-Alone IP Telephony

9. Stand-Alone IP Issues • Purchase, license renewals, maintenance cost, disaster recovery and technical support the responsibility of using department • Certified technicians, in-service training, demand from corporations make having own technicians difficult • New versions of software can bring additional cost and disruption to service • Number changes are required • Integration of multiple call managers is difficult to manage

10. NCC Managed IP Telephony

11. NN Telephone Architecture • Telco IP Telephony and legacy Centrex telephone work as one integrated system • Calls from public can be transferred to any telephone • Operators can support all telephones • Auto Attendants and Automated Call Distribution calls can send calls to the appropriate telephone • Allows phase-in of IP Telephony as the department networks are brought up to the standards • Stand-alone IP Telephony can have basic connection but no call handling or network features. These type of sites are discouraged

12. So Why NCC Managed IP Telephony? • Cost • Average cost now is about $35 per phone (including features) per month, IP cost is $12.99 for most phones • With IP Telephony many service changes can be done by NN employees compared to the current telco charge for most changes on Centrex • Voice Mail included in IP Telephony basic charge (Centrex cost $4.95 per month)

13. So Why Frontier IP Telephony? • Technology • It’s not a matter of “if” but “when” – old technology will be phased out • IP Telephony has powerful network diagnostics • LAN upgrades part of NNTU plan • WAN upgrades part of NNTU plan

14. So Why NCC IP Telephony? • Capabilities to communicate better, more conveniently, and more effectively • Telephones can be anywhere on IP network • New phones have capability of multiple lines (view status of other phones), button access to features, speaker phone • Powerful management control of telephones through online tools and reports

15. IP Telephony Capabilities • All current features, no extra cost for almost all • Voicemail for all phones, where desired • Direct Inward Dialing where desired, answering point screening available when needed • Directory (Company and Personal) • Auto Attendant Functionality at extra cost as current • Hunt Groups • Enterprise Administration, Reporting and Billing • 911/E911 • Multi-site connectivity with 4 digit dialing • Conference calling and bridging • Call log

20. IP Telephony Readiness • NNTU, Dept of Information Technology and NCC will assist in evaluating your site • Office wiring, patch panels and enclosure • Switch (POE and QOS) and UPS • Network connection • DIT fiber or wireless, MetroE, DS-x, DSL • IP Telephony configuration and features

21. IP Telephony Readiness • IP Telephony Engineering Site Survey • Complete as much as you can • Kyle King, NNTU and Ben Gorman, DIT are available to assist you • Floor Plan • Early completion assists in getting network upgrades and IP Telephony service sooner

22. Engineering Site Survey Managed IP Telephony INSTRUCTIONS FOR COMPLETION

25. List make, model, software level and port capacity of the Ethernet switching equipment: NNTU Comment: NNTU also needs to know if the switching equipment is on a UPS. From this information, NNTU is looking to see Power over Ethernet and Quality of Service capabilities. QoS is mandatory and PoE is highly desireable.

26. List the make, model and software level of all routers: NNTU Comment: NNTU also needs to know if the network equipment is on a UPS.

27. NNTU Comment: NNTU also needs to know if there is a wall or rack enclosure. New cabling/patch panels may still be necessary if the terminations and patch panels are inadequate. Temporary usage may occur if the cabling is not optimal but is serviceable until an upgrade is completed.

28. NNTU Comment: VoIP uses a small amount of bandwidth and only when calls are active. However, if your bandwidth is slow or inconsistent now, VoIP will have an effect, especially for DSL. If you have a DIT fiber connection or Metro Ethernet connection VoIP should have no discernible effect on your network.

29. NNTU Comment: No additional network connections are generally needed for the IP phone. The VoIP phone is normally inserted in front of PC on the network connection.

31. NNTU Comment: When power to the phone or the network is interrupted, there will be an approximate 3 minute delay to reset the network to the VoIP phone, Ethernet powering from a UPS protected switch is preferred. For a small office that only has a DSL router, a UPS that can serve the router and at least some phones would be preferred.

32. SURVEYOR INFORMATION

33. Floor Plan Completion • Important to get a floor plan for wiring and phone programming • Installing new wiring and patch panels is likely for many locations • Those sites with completed floor plans are more likely to have their wiring upgraded in the first project phase

34. Sample Floor Plan

35. Closer view Instructions (Using the Legend) • Identify where all telephone, computer and fax machine jacks are located. • By each telephone line locations, list the complete telephone number with area code and identify if the telephone line is a single or business line (set. • Identify where the computer equipment network closet (room) is located.

36. Network Connection • Connections to DIT’s WR fiber are best way to connect • Bandwidth issues are being addressed and funded • DIT’s WR switches are being upgraded to POE and UPS power • IP telephones will get power through ethernet and will not be affected by power spikes or outages • Connection to DIT fiber is funded

39. New Wiring/Enclosure Needed

40. New Wiring /Enclosure Needed

41. Acceptable Wall-Mounted Wiring Enclosed with doors and lock if required Network equipment is mounted in cabinet
