E61 is a RIS receiver module for remote control of ingress switches. It is compatible with Teleste E3 amplifier and E8 node platforms.
E61 supports Remote Ingress Switching (RIS), allowing return path ingress switch control via forward path data link. RIS uses narrowband one-way FSK communication channel and automatically searches for and locks to HDM155 RIS controller’s carrier within the tuning range.
E61 is installed into the amplifier / node RIS module slot.
