Features

  • A/B SwitchSwitch to provide switching from signal source A to signal source B or vice versa. The switching can be done manually or automatically based on RF-Sensing or TRAC or remote controlled via Dig-In or SNMP.es
  • A/B Sensing SwitchA Sensing Switch is a DPST switch using the RF Sensing functionality for automatic switchover in case of signal loss. es
  • Transfer Switches
  • Splitter/Combiner
  • Optical switches

It is based on the International Mobile Telecommunications-2000 (IMT-2000) specifications. Common 3G standards are UMTS, HSPA+ and EDGE. Switches
  • E1/T1 Switches
  • Automatic switching via RF SensingRF Sensing measures the accumulated RF power over the entire bandwidth. This value is a quality indication to either just send an alarm to a M&C System or to perform a redundancy switching fully autonomously.
  • Automatic Switch BackIn case of redundancy switching a device equipped with the Option "Automatic Switch Back" will switch back from backup to main port after the status of main recovers.
  • Main/Backup SwapOther than traditionally it is the case for redundancy switches were In A is dedicated being the main input and In B the backup input, the functionality Main/Backup Swap changes dynamically the role of main and backup channel. After redundancy switching from input A to input B, B gets the role of the main input while A is the backup input and vice versa. - TRACThe TRAC (Trap Receiver Action Controller) option is intended to provide means for additional automatic remote switching capabilities of a device. With this functionality, the device is able to perform switching actions based on SNMP traps received from any external equipment without additional M&C software. In addition, the IP Monitoring functionality continuously checks the availability of external equipment used in any TRAC configuration. The device is able to command itself and other equipment via SNMP. (Trap Receiver Action Controller)
  • Power Supply RedundancyPower supply redundancy is the duplication or even triplication of the power supply as a critical component or function of the system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe. In case of no failure load sharing between the installed power supplies ensures an increased MTBF.
  • DEV Web InterfaceThe DEV Web Interface is an enhanced graphical user interface (GUI) to monitor and control all functions, features and settings available for DEV devices.
  • SNMPSimple Network Management Protocol (SNMP) is a remote protocol used for managing devices in M&C Systems. Support
Benefits

  • One chassis for all applications
