Zenitel specialized products for TETRA Confined Area applications
Specially developed for and in cooperation with Dutch Confined Area customers, CFocus now brings to market Zenitel’s innovative products;
- Active pilot tone cable monitor - ZPCM6000
- Redundancy switch - ZTRS6000
Active pilote tone cable monitor - ZPCM6000
The Cable Monitor ZPCM6000, developed by Zenitel allows monitoring of both cable breakage and changes in path attenuation in combined antenna networks.
Characteristics
- Detection of cable breakage
- Detection of changes of path attenuations
- Automatic adjustment
- Communication via TCP/IP or RS485
- Fully webbased configurable
Optional
- Interface with Zenitel SCADA system ZTSS6000
- Data communication via coax cable
Description
The module ZPCM6000 can be used either as a transmitter or as a receiver unit. The integrated highly sensitive and selective radio modem allows separately monitoring of every distribution channel within a complex antenna network. It provides the exact attenuation by measuring constantly the RSSI values within the distribution channel.
This information including information like power voltage, temperature, sense input signals, is available via the webbased interface available via TCP/IP on the receiver unit. When a training cycle is selected the units adjusts itself automatically.
After this training cycle the unit will be ready to generate alarms depending on user definable trigger levels. The module can be powered by an external powersupply or via the coax cable..
Redundancy switch - ZTRS6000
The redundancy switch ZTRS6000, developed by Zenitel, enables the possibility to connect 2 repeaters / base stations to build an redundant configuration for indoor and special coverage locations.
Characteristics
- Redundant repeater configuration
- Frequency range 136 - 2200 MHz ( 2 bands)
- Continuously monitoring of the output power from the repeaters
- Automatically switching in case of malfunction of one of the repeaters
- Communication via TCP/IP or RS485
- Fully web based configuration and monitoring
Options
- Interfacing with Zenitel's SCADA system ZTSS6000
- SNMP functionality
Description
In HF communicaton systems normally 2 repeaters are used to cover their own part of the antenna system and distribute the HF signals. By implementing the Zenitel redundancy switch it will never occur that malfunction of one repeater will lead to communication problems in that part of the system.
The redundancy switch will continuously monitors the HF signals provided and will automatically switch/connect the remaining repeater to that part of the system in case the measured values are below user definable triggerlevels or in case of a complete malfunction of a particular repeater. This results in a redundant system where in case of a emergency one repeater will distribute the HF signals into the complete antenna system.
The status of the redundancy switch and both repeater / base stations are presented by the LED's at the front panel of the switch. Via the web based tool it is possible to remotely configure different parameters and continuously monitor the provided HF power output.
