The basic design for a Scout–IDAS Multi-Site Trunking system is determined by the number of endpoints required and the number of consoles that require access to those endpoints. On the console, an IDAS  Multi-Site Trunking endpoint (talkpath) can represent both a group and a unit—console connections are treated much the same as subscriber unit connections. The group associated with an endpoint can be either static or selectable.

When designing a system, the number of desired endpoints and geographical locations for consoles determine the number and type of licenses needed. Review the following to understand how components in a Scout–IDAS Multi-Site Trunking system can be scaled.

  • One VPGate license can control 24, 40, 80, or 160 total endpoints, depending upon the VPGate license level purchased. Of the total endpoints in the VPGate license, up to 16, 30, 60 or 100 endpoints can be IDAS Multi-Site Trunking endpoints, depending on the supplemental NXDN license purchased.
  • Clients migrating to an IDAS Multi-Site Trunking system from an IDAS conventional system must purchase a supplemental NXDN trunking license to enable each IDAS talkgroup or individual call endpoint.
  • Clients covered by ScoutCare at the time of Scout version 4.5 release are entitled to receive the 4.5 software update at no additional charge. On-site assistance provided by Avtec to execute the upgrade would incur an additional charge.
  • An Icom IDAS Multi-Site Trunking system can support a maximum of 48 sites, each containing up to 30 repeaters. Repeaters and sites can be interconnected using an IP network.

In a Scout–IDAS Multi-Site Trunking system, VPGate connects to a master repeater at each site. The number of connections per site is limited to 8. The total number of connections that can be made, and simultaneous groups monitored, is therefore limited by the quantity of available sites.

Scout can interface with more than one IDAS Multi-Site Trunking system, and multiple VPGates can be used for redundancy. In any multi-system environment, Scout unifies a command center by connecting simultaneously to multiple radio systems for different reasons. For example, different systems could represent different agencies or locations for an agency.
