• 3-contact dry relay for external alarm systems via a 3-pin terminal block connector
System Timing and Clock Port
The iDSL Multiplexer’s system timing may be derived from the composite Clock Port, an Internal Clock from
an on-board chip, or a Network Clock from the T1/E1 WAN interface. The system timing is con-figured
through the NMS. The Clock Port features are:
• Input for an external 64 kHz BITS (Building Integrated Timing Supply), reference clock.
• External reference drives timing for all iDSL and WAN ports.
• Selectable Master and Fallback Clock
