OMU squelch interface

Order number: 7000 00753976

The installation of this product enables additional noise suppression (also known as squelch or uplink muting) between an optical distribution system and a base station.

Please pay attention to the frequency range to be ordered.

This is an active suppression of noise in large distribution systems, such as campus solutions or metropolitan concepts.

• Nominal gain of 0dB, can therefore also be used in existing systems
• Noise suppression option for uplink and/or downlink
• Central noise suppression at the RF handover point to the base station
• Channel-selective mode
• Timeslot-based muting in channel-selective mode
• Easy setting of gain and noise suppression threshold via webGUI
• Compact design for cabinet mounting
• Ethernet LAN interface for local operation
• Alarm contact for integration into local fault reporting system
• 4 potential-free alarm inputs for monitoring additional devices

Additional technical information regarding typical group runtimes (delay):

• Channel-selective TETRA mode 90kHz filter: 11us
• Channel-selective TETRA mode 60kHz filter: 14us
