2 IDAS OPERATION ■■IDAS operation The transceiver provides Icom Digital Advanced System (IDAS) that meets the 6.25 kHz emission mask requirements for narrow banding, and increases efficiency of channel allocation and use of spectrum using the NXDN common air interface. DDIDAS Conventional operation The IDAS Conventional system enables efficient conventional operation in the digital mode. ➥➥Push [Zone], then push [CH Up] or [CH Down] to select the conventional zone. DDMulti-site conventional operation The Multi-site Conventional system can support up to 16 sites (each site has one repeater) through an IP network, and enables efficient conventional operation in the digital mode. ➥➥Push [Zone], then push [CH Up] or [CH Down] to select the Multi-site conventional zone. DDSingle-site Trunking operation The Single-site Trunking system enables further effective channel management by sharing a minimum number of channels with a large number of users. ➥➥Push [Zone], then push [CH Up] or [CH Down] to select a Single-site Trunk zone. DDMulti-site Trunking operation The Multi-site Trunking system can support up to 48 trunked sites through an IP network. This enables the users to communicate with stations through the interlinked trunked site. Each site can have up to 30 repeaters. ➥➥Push [Zone], then push [CH Up] or [CH Down] to select the Multi-site Trunk zone. NOTE: During the Single-site or Multi-site Trunking operation, you can receive and transmit digital calls in the same way as in the conventional mode. 8
