The IEEE 1588 card can be configured to operate as a PTP grandmaster or as a PTP slave.

S 1 S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S Blocked signals and multipath cancellation significantly increase GPS acquisition time. Multipath cancellation is caused by reflected signals that reach the antenna out of phase with the direct signal. Multipath cancellation and blocked signals are typically caused by vertical reflective objects positioned to the side and above the antenna.

A 150 foot length of RG-59 coax cable of has a loss of 16-21 dB, which meets this requirement. Abide by the minimum input gain requirements if using other cable types.

Symmetricom recommends using the standard 12-volt capable antenna and cable provided with the GPS receiver. 1 Figure 4: GPS Signal Strength Requirements Connect the GPS antenna cable to the GPS receiver’s ANTENNA connector at the rear of the XLi. Note: Use a 12-volt capable GPS antenna.

Distributing non-TAI time over PTP while the PTP slave is a reference source will have a predictable effect on the XLi’s system time. 1 Note: Later on, when reconfiguring the IEEE 1588 card as a PTP master, use F119 to set the GPS receiver as the PRIMARY reference source.

When a system alarm event occurs an SNMP trap alarmSystemNotification is sent to the SNMP managers previously configured to receive traps. Included in the trap message are the variables contained in the systemAlarmData group: IP address, timestamp, alarm code, and the F73 status string.
