Dali’s tHost is a digital intelligent and programmable software platform that forms the head-end of the tSeries network. The tHost accepts the input from cellular operators’ base stations and bi-directionally transfers four separate cellular bands to Dali t30™ or t43™ remote transceivers. It can support up to six independent optical fibers. It also provides Ethernet backhaul at 1 Gb/s for additional devices such as Wi-Fi and security cameras.
The tHost is the “core” of the system and performs a broad array of functions including digital signal processing, framing/deframing and serializing/deserializing, digital up/down conversion and RF up/down conversion. It orchestrates all network functionality under software control and its capabilities include network management, capacity-on-demand, channelization, Wi-Fi integration, security and public safety, and customer based applications.
The tHost connects with Dali’s t30 indoor low-power remotes and t43 outdoor high-power remotes in a “plug-and-play” manner. When a remote is added to the network, it is automatically identified and configuration is performed at the user interface. To serve additional wireless operators, tHost units can be cascaded and their signals are digitally processed and combined. The aggregated content are sent over optical fiber to the remotes. Also with Dali’s patented power allocation technology, it controls and enforces power levels at the dedicated remote on a per operator basis.
tHost provides simplified gain and delay compensation settings for all remotes, SNMP remote monitoring, alarm, and control functions, on-demand system reconfiguration, and remote upgrades via the Web. Other features include real-time measurement and display of uplink and downlink RF power levels, uplink and downlink gain/delay to each remote, and many others.
