Analog Interfaces

The Rhino channel bank provides either FXS or FXO analog interfaces, both with digital technology that utilizes a dedicated Digital Signal Processor (DSP) for monitoring real-time line characteristics.

•FXS – The Rhino FXS analog interface provides standard battery and ringing voltages to each of up to 24 loop or ground start analog channels.
Each channel provides:
•Digital DSP
•Echo cancellation
•Line current limit from 18ma to 45ma
•Tx and Rx gain control of -5db to +6db
•Power down control from 1 to 3 secs.
•Ring cadence control

•FXO – The Rhino FXO analog interface requires a standard POTs analog telephone line up to 24 inputs
Each channel provides:
•Digital DSP
•Dynamic impedance matching
•Tx and Rx gain control of -15db to +12db
•Ring cadence monitoring timer

•FXS/FXO Modules – The modular Rhino channel bank can be ordered with four to 24 channels of either FXS or FXO analog channels installed in increments of four channels up to six modules. When using the Rhino in fractional T1 applications, there is no need to install a 4-channel analog card in those slot positions.

All Rhino channel banks come in 110VAC, 220VAC and -48V DC models. The -48V can be used to power the Rhino, or for external battery backup to AC power.
