Page 6: Summary
When an error on the selected source is observed an error condition is generated via SNMP and dry contacts and a new source is selected between the available ones as per user configured priority. MXS-EVO is quite simple to use and to set-up. Every function can be accessed locally from the LCD panel and remotely via WEB or SNMP.

Page 10: Main Operation
MXS-EVO - MANUAL Main Operation The main purpose of the MXS-EVO is to provide stable output signals of Time (PPS, E1, IRIG code, NTP/PTP) and Frequency (10 MHz, 2.048MHz), and to enable the synchronization of the network. This is allowed by the application of algorithms, tuning an high-stability internal oscillator.
Page 11 Rec G.812 (ITU-T) MXS-EVO allows to choose on which of the 30 (from 2 to 32, excluding 17) timeslots of the E1 frame transmit the PPS signal. As default, the signal is sent and received on timeslot 32. The timeslots 1 and 17 are used to send sync and control data by E1.
Page 12: Ntp
• X6 from 0 to 1 when there is loss of synchronization; MXS-EVO allows to choose which "column" (from 4 to 8) of bits use to transmit the value of the signal quality. By default this value is sent and received on the column 8.
Page 13: Ptp (Ieee 1588)
PTP (IEEE 1588) The MXS-EVO supports the IEEE 1588-2008 (version 2), also known as Precision Time Protocol, both as master and slave. When connected to an appropriate device compatible to the IEEE 1588 standard is able to synchronize the slave apparatus with a precision well below the micro-second.

The device disciplines its internal clock from the selected reference (GPS, PTP, IRIG-B, NTP) and distributes it with the following rules: NTP (UTC timebase as per standard) • PTP (TAI timebase as per standard) • ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- MXS-EVO – Manual – Rev 1.7 - 15 -...
Page 16: Switchover Function
IRIG-B signal Switch Policies The MXS-EVO permits to chose the priorità of the various sources. Priorità is bigger when the value is bigger. 0 inhibits the source. When the device is configured for automatic switchover two different policies can be used: Switch &...
Page 17 Characterization of Sources MXS-EVO was also designed to compare the quality of the different sources provided to apparatus, analyzing the ratio ∆f / f (variation of the frequency value on the nominal frequency) of each source. This analysis is supported by a graph (that can be generated by the Stability Chart button in the Main Panel) which shows the trend of these ratios over time.
Page 18 MXS-EVO - MANUAL It is also possible display the progress of these distances over time (using the button Distance Chart in the Main Panel). ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- MXS-EVO – Manual – Rev 1.7 - 18 -...
