Other input cards accept DS1, E1, analog, and composite clock timing reference sources. The performance level of each clock exceeds the relevant industry requirements in both locked and holdover modes. The ST2E improves upon these capabilities and rovides fault tolerant clock performance suitable for PRS applications. A fully equipped system can provide over 300 redundant timing outputs. Output signals and formats may be intermixed in any shelf and are protected by automatic switching.
All positions are available for timing outputs, sync clock insertion, or other applications.
Status Control DCD-519 status is indicated locally by LEDs and relay closures. Current status, real-time alarms, sync monitoring, and the event log are transmitted autonomously or on demand.
