PathNavigator AdvantagesPathNavigator Advantages

IP Specific AdvantagesIP 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

IP Specific Advantages (cont’d)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

ISDN Specific AdvantagesISDN 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

Other PathNavigator AdvantagesOther 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

Polycom OneDialPolycom OneDialTMTM – How it Works – 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

Extensive Knowledge is Maintained on Extensive Knowledge is Maintained on How to Reach EndpointsHow 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)

PathNavigator Address Resolution StepsPathNavigator 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

PathNavigator Address Resolution PathNavigator Address Resolution Steps (cont’d)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

Intelligent DialingIntelligent 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

Simplified Gateway DialingSimplified 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

Least Cost RoutingLeast 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

RegistrationRegistration

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

Automatic ISDN & E.164 AssignmentAutomatic 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

RAI/RACRAI/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

Neighbor Gatekeeper SupportNeighbor 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

Used by a gatekeeper to determine the bandwidth requested by an endpoint.Gateway – connects different protocols, e.g., H.323 to H.320LRQ – 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.
