1207A Auto Switch

With intense competition and subscribers demanding ever more from service providers, quality and availability of service have never been more critical to maintaining and
expanding your subscriber base.
To complement our range of our high quality frequency and timing references, Precise
Time and Frequency, Inc. has now introduced a new RF, Digital, and Time Code, Auto Switch / Distribution unit to insure you
deliver the performance and reliability your customers demand.
The ptf 1207A delivers up to eight channels of fully redundant, frequency and timing references to critical applications such as Satellite Communications, Broadcasting, WiMax and others, with NO SINGLE POINT OF FAILURE.

The unit accepts two inputs on each channel from separate sources (primary and backup), monitors the inputs for signal integrity, and outputs the primary signal with no degradation of the input.

If the primary input on any channel fails, the unit will automatically switch to the backup input and indicate a primary signal fault.

The unit will accept up to eight channels simultaneously and independently switch on each channel.The unit also includes full remote monitoring and control via RS232 and Ethernet interfaces.

• Switches Multiple Signal Pairs
• Fast Switching time • Broadband range
• Latching switches
• Remote Monitor /Control
• Power fail “failsafe” operation
