Lynx Hot Standby Protection Switch
Monitored hot standby hardware protection
Automatic switching to standby mode
The protection switches operate in conjunction with two Lynx radios and one antenna at either or both end of a link to provide monitored hot standby (MHS) hardware protection to the on-line radio.
When there is a condition indicating a hardware failure affecting the on-line radio, the Protection Switch simultaneously switches all radio functions including transmitter/receiver RF, data, orderwire, diagnostics, and auxiliary data ports to the standby radio.
The status is displayed via the front panel LED indicator as well as at the alarm and status monitor points located on the rear panel. The output power level can be calibrated via a push button to set the power alarm threshold. Lock-on switches allow for testing the standby equipment.
Interoperability with Lynx radios*
Four models of protection switches are available:
The 4T1 and 4E1 models interoperate with 1xT1/1xE1, or 2xT1/2xE1, or 4xT1/4xE1 Lynx radios in the 2.4 or 5.8 GHz ISM bands. The 8T1/8E1 model inter-operates with 5.8 GHz Lynx radios up to 8T1/8E1 capacity. The DS3 version supports Lynx DS3 radios.
