2.2 ProgrammingProgramming Guide 17OthersDetailed ExplanationsGatekeeperThe following are the general functions of a gatekeeper:• Dialled number-to-IP address translation• Authentication• Bandwidth controlIt is possible to employ a VoIP network without the use of a gatekeeper, because the card is equippedwith internal address translation capabilities. However, should the network contain dozens of cards,maintenance of address translation tables in individual cards can become a strain.A gatekeeper is useful in this case, because with the gatekeeper it is possible to consolidate themaintenance. (However, you still need to programme each card on the network with its own addresstranslation information. For details, refer to "2.2.6 Address Translation Table—GW Entry" and "2.2.7Address Translation Table—DN2IP Entry".) For more information about gatekeeper functions, consultthe documentation of the gatekeeper.When using a gatekeeper, make sure to choose a compatible model. For more information aboutgatekeeper compatibility with the card, consult a certified dealer.* Gatekeeper Connection Checking Interval (min) 0-1440minSpecifies the time (in minutes) between periodic checks ofconnection to the gatekeeper.When the primary gatekeeper fails, these checks can detectthe failure. In this case, the connection automatically switchesto the secondary gatekeeper if it is available, so that thenetwork remains functional.0 0 (disable),1 to 1440* Call Signaling ModelSpecifies whether to carry out a call control (H.225) processdirectly between the cards or through a gatekeeper.Direct call control is typically preferred because it involvesless network load.Direct Direct,Routed (viaGatekeeper)Parameter & Description Default Value Range# Fast ConnectSpecifies the use of the Fast Connect feature.Using Fast Connect simplifies the communication process sothat calls can be established quickly.Generally, there is no need to change the default value.Use Use,Don't useParameter & Description Default Value Range
