22. The only product to do IP and ISDN routing Routes calls through Least-Cost across multiple PathNavigator servers Provides Polycom OneDial which improves call connection rates Gives high availability with full redundancy in a second server Turns any endpoint into a Multi-point capable system* Enhances the Polycom Office with automated management features Calculates video bandwidth restrictions through all segments of the network Can manage up to 3000 endpoints on one server * Requires MGC-100 PathNavigator Advantages

23. IP Specific Advantages Calculates video bandwidth restrictions through all segments of the network Gatekeepers don’t calculate bandwidth across zones Conference on Demand for IP-only devices Gatekeepers don’t have this required MCU capability Dial using names, email addresses, URLs, and WINS/DNS Gatekeepers don’t have this level of dialing capability Automatically assign E.164 aliases (extensions) based on network topology (location) Gatekeepers assign numbers based on one generic definition

24. IP Specific Advantages (cont’d) Monitor and/or prevent unauthorized calls to registered endpoints Gatekeepers only monitor/prevent registration from unknown endpoints, not the call itself Permit registrations from known endpoints (pre-defined) and network address ranges Gatekeepers can only limit based on known endpoints Permit internet-based endpoints to register through a VPN Gatekeepers cannot do this Simplified and extensive diagnostic monitoring

25. ISDN Specific Advantages Alternate Routing PathNavigator CAN route via ISDN if IP bandwidth is unavailable Gatekeepers cannot route calls via ISDN if the IP path is blocked Lower ISDN costs as fewer DID lines required in the enterprise Least-Cost Routing PathNavigator can use a least cost routing mechanism using IP for major portions before calling over ISDN Gatekeepers do not understand the ISDN world Policies to prevent unauthorized ISDN dialing

26. Other PathNavigator Advantages Gives users telephone-like interface with OneDial Gatekeepers use complex codes for all gateway calls Turns any endpoint into a Multi-point capable system (Requires MGC and Virtual Conference Suite) Gatekeepers do not integrate to this level with any bridge Enables users to migrate from ISDN to IP networks Gatekeepers don’t understand the ISDN world Tracks bandwidth policy across multiple networks and links which enables complex IP video networks No other gatekeeper today can do this Automates deployment with Polycom equipment Gatekeepers don’t have any Polycom specific knowledge

PathNavigator Architecture Administrator(s) Device Interface Registration Provisioning – ISND DID & E.164 Policy Management Address Resolution & Intelligent Dialing Routing – Least Cost, Alternate, & Telephony Rogue Detection CDR Diagnostics/ Network Performance Intelligent Network Routing Engine LAN IP Endpoints WAN IP Endpoints VPN IP Endpoints ISDN Endpoints GWGW GWGW CSV File Reports Web Interface

34. Polycom OneDial TM – How it Works Option 1: Choose a Name from the Global Directory PathNavigator Automatically Routes Calls Over IP, ISDN, through Gateways, or Whatever is Required PathNavigator Automatically Adds or Removes Area Codes, International Dialing Prefixes and Country Codes Option 2: Dial A Number Like a Phone 4-Digit Extension for Internal Calls, or Dial “9” for Outside (Gateway) Calls No Gateway Call Prefixes Required Regardless of the Speed of the Call Dialed

35. Extensive Knowledge is Maintained on How to Reach Endpoints Internal IP address (DHCP or static) External IP address (direct or NAT environments) Natively (on the ViewStation QoS settings page) H.323 enabled FW –Cisco PIX –Checkpoint FW Polycom MGC Firewall/Gateway ISDN # Natively (H.320 capable unit) Through a Gateway using DID, extension, or DTMF (TCS-4)

36. PathNavigator Address Resolution Steps 1.If the dial string has a service code, e.g., “9”, route to that service already defined 2.If the dial string is an IP address, send the necessary ARQ and connect the call 3.If the dial string is an Alias, send ARQ to resolve it  H.323 ID  E.164  URL  Email  WINS/DNS

37. PathNavigator Address Resolution Steps (cont’d) 4.If alias unresolved in last step, send LRQ to all neighbor gatekeepers with same alias list 5.If not resolved by neighbor gatekeeper, send request to network to resolve WINS or DNS 6.If not resolved, use Universal Dialing process with DNS name or email 7.Last, check if it is an ISDN number that can be dialed directly

38. Intelligent Dialing For PSTN calls (H.320 or POTS), dialed numbers are adjusted to be appropriate for the location of the gateway making the call PathNavigator understands the physical layout and location of gateways throughout the video network It will automatically add or subtract the international dialing prefix, country code and area code from the number being called This is the same technology used in the Directory Services of Global Management System

39. Simplified Gateway Dialing When gateway capabilities are required, the user can simply dial a single digit, i.e., “9”, to have the call routed properly This single “service request” will enable all registrants in the network to use any gateway in the network, e.g., gateway line hunting This will enable all dialing speeds up to the limits of the policies No Additional Service Codes Required Replaces current complex scripting processes used by competitive offerings

40. Least Cost Routing Administrator loads cost information for each gateway on the network by area code When placing PSTN calls, all gateways on the network are sorted by cost The first gateway to meet the bandwidth availability, policy, and RAI/RAC is used

41. Registration PathNavigator will register endpoints with a multitude of aliases, external IP address, an ISDN DID, default group policy association, available services, etc. Different registration security levels are available Open (everyone can register) Only predefined endpoints and specified networks Only predefined endpoints

42. Automatic ISDN & E.164 Assignment Automatically assign ISDN numbers For Direct Inward Dial (DID) in H.323 –Simply enter the trunk DID range from the CO into PathNavigator Automatically assigns appropriate E.164s to enable DID Automatically assign E.164 extensions Administrator can set ranges of extension numbers based on Network Topology policy –For example, NY endpoints get x8000 - x8499 and then LA gets x8500 – x8999, etc. Works with all industry standard gateways

43. RAI/RAC Resource Availability Inquiry – sent by the gatekeeper Resource Availability Confirmation – reply from the resources Standard H.323 function designed to enable gatekeepers to determine resource availability on the network If resources (ports on gateways and MCUs) are available, they respond to this message and permit the call When devices are low of resources, their response indicates so If no resource is available, the call will be denied

44. Neighbor Gatekeeper Support Neighbor gatekeepers use LRQs (Location Requests) to determine if their neighbors have the required endpoint information in their registration database LRQs between two PathNavigator units will pass the IP as well as ISDN number for alternate routing

45. Server Requirements Processor: 2 GHz Memory: 1 GB OS: Windows 2000 Server or Windows Server 2003 Database: MSDE or SQL 7.0 or higher IIS: 5.0 Client Requirements (IT Administrators) OS: Windows 2000, or XP Browser: Internet Explorer ® 6.0 or higher System Requirements

46. Gatekeeper Routing Modes

47. Calls In Direct Mode PathNavigator Data H.245 – Call Control H.225 – Call Setup Fully supported by PathNavigator. Generally used by a master gatekeeper when in a hierarchy environment.

48. Calls In Direct Mode (Details) PathNavigator ARQ H.225 – Call Setup ACF ARQ ACF H.225 – Call Setup H.245 – Call Control BCF BRQ BCF BRQ DCF DRQ DCF DRQ Bandwidth Disconnect Call Activation Data

49. Calls In Routed Mode (H.225 Routed) PathNavigator H.225 – Call Signaling Data H.245 – Call Control H.225 – Call Signaling Fully supported by PathNavigator. This is the most common gatekeeper mode used by all companies today.

50. Calls In Routed Mode (H.245 Routed) PathNavigator H.225 – Call Signaling Data H.225 – Call Signaling H.245 – Call Control PathNavigator does not support this option

51. Calls In Proxied Mode PathNavigator H.225 – Call Signaling H.245 – Call Control Data PathNavigator does not support this option. It places a heavy burden on the network sending ALL video data packets through one point on the network.

52. Glossary ARQ/ACF – Admission Request/Confirmation. Used by a gatekeeper to determine if the endpoint has permission and resources available, then return the necessary IP address to connect. BRQ/BCF – Bandwidth Request/Confirmation. Used by a gatekeeper to determine the bandwidth requested by an endpoint. Gateway – connects different protocols, e.g., H.323 to H.320 LRQ – Location Request. Used by a gatekeeper to get endpoint information from Neighbor gatekeepers. NAT – Network Address Translation. Used to oversubscribe external IP addresses or when using a firewall. POTS – Plain Old Telephone System. PSTN – Public Switched Telephone Network. Includes POTS and ISDN. RAS – Registration/Admissions/Status – Main responsibility for a gatekeeper.
