WISI TOPLINE HEAD END
14MM-OV50A
Wisi Topline II Headend Base Unit
For the best Headend, choose WISI Topline II.
Already with an outstanding reputation, WISI Headends continue to
dominate as the Headend of choice for quality and reliability. With an
extensive range of modules to choose from, a WISI Headend is perfect for
any senario - from Channel Processors to Modulators, Transmodulators to
Digital OFDM Demodulators. Every module is simple to install and even
easier to configure. Use WISI today and drive your MATV System further.
The WISI Advantage
• Base Frame features a High Output GaAS amplifier
• Each base unit can house up to 10 modules
• Two high isolation 6-way splitters in each OV50A
are used for distribution to module inputs
• NMS compatible for remote configeration or monitoring
• Backwards compatible with Topline I modules
• Wall mounting or 19-inch rack mountable
• Individual Microprocessor Control
- no external programmer is required
• Fully Frequency Agile
• Highly selective SAW Filters, or Vestigial Side Band
modulation and optional Adjacent Channel operation
• The headend used in the International
Broadcast Centre Sydney Olympic Games - 86 Chs
14MM-OV52
WISI Commander Remote Control System
• Fits into the 14MM-OV50A Base Unit & allows PC based control of the WISI headend
• Connect your laptop directly or via dial-up modem enabling remote access
to change settings on modules as though they were sitting in front of you
• Allows you to remotely monitor your installed WISI Headend
14MM-OV52 - IP adressable controller featuring SNMP
