HDM155 RIS Controller
The HDM155 is a RIS controller and communicates with 电话este RIS (Return Ingress Switch) compatible amplifiers and nodes. It is the heart of the RIS system and communicates with RIS receiver modules via one-way forward path 射频链接. The HDM155 maintains a list of RIS receivers and their ingress switch statuses and provides Ethernet connectivity between element/network management system and the RIS system.
Features at a glance:
- HDO module mechanics
