analog, MDC 1200, ACIM Link, digital and mixed mode channels simultaneously. An ECCGW may also be used in
combination as a console site router or an RF site router, provided the WAN link is not redundant.
7.6.3.1 IP Conventional Gateway
ECCGWs can support up to 16 G-Series-based ASTRO 25 conventional channels through the radio system's IP
network. The IP interface uses the same Ethernet cable that the ECCGW uses for everything else. The 16 |P-
connected channels are in addition to any analog or V.24 channels that may also be connected to the ECCGW.
7.6.3.2 Conventional Site Controllers
The conventional site controller allows dispatch console users to continue to access and control local conventional
channels if connectivity to the radio system’s zone controller is lost. This mode of operation is often called “fallback
operation” or “site conventional operation.” While in fallback operation, the dispatch consoles continue to support
the vast majority of their capabilities and features. Only one conventional site controller is required per console site
or conventional subsystem. This single conventional site controller can support the full set of dispatch conscles,
archiving interface servers, and CCGWs in a console site or conventional subsystem.
