I I Outline The VoIP-TA The VoIP-TA is a one-channel Internet telephony adapter that provides Internet telephony services conforming to industry standard H.323 version 2 specifications. It can be connected to a conventional analogue telephone or G3 facsimile machine. Once installed, VoIP-TA units use the Internet Protocol (IP) network to bridge the distance between units at a fraction of the cost associated with conventional telephony methods. * Gatekeeper is necessary when more than 100 IP add

Personal computer (PC) Connect a PC connector to the PC port at the back of the VoIP-TA unit using an unshielded twisted pair (UTP) straight cable (categories 3 to 5). If both a PC and LAN are to use 100BASE-TX communications, use category 5 [max. 100m]. It is recommended that only one PC is connected to avoid voice deterioration. Note LAN Connect the LAN connector to the LAN port at the back of the VoIP-TA unit via a cross cable (UTP categories 3 to 5). If connecting to a hub, use a straigh

Cautions During installation • All cables used to connect the equipment must be accessories of the equipment or suitable to fit the equipment. • Make sure the AC power plug is disconnected from the power outlet when connecting the FG cable to the unit. • When an exchange machine, such as PBX or EKTS is connected to the TEL port of VoIP-TA, the sound quality may deteriorate. Only one exchange machine should therefore be relayed between the VoIP-TA unit and telephones. • Interference noise may o
