NexeTalk Telephone Interconnect
(NTI)
1 Introduction
NexeTalk Telephone Interconnect (NTI) is an integral part of NexeTalk Suite. It is also possible to install NTI as a
standalone application. The telephone gateway allows calls between Nexedge radio users and telephone subscribers. In Diagram 1, you can see a typical scheme of a Nexedge radio network. The network can include any number of Kenwood Nexedge sites and groups of users.

NTI is an IP-based software module that makes connection between radios and phones much more comfortable
and cost-effective. It does not require any additional hardware. NTI connects to telephone lines via SIP 2.0 capable PBXs. Analog PBXs may need a hardware adapter supporting SIP.
In Diagram 1, internal phones are connected to the PBX, either via analogue or digital lines. The PBX allows making internal calls and connecting internal telephones to the PSTN. Telephones from the PSTN can also access internal phones via the PBX.
