Identifies failures on electrical cables like short-circuits or breaks of a wire
pair and indicates the distance from the instrument to the fault.

Specify quality level (QL) of the transmitted Ethernet signal.
SyncE functionality is available when the interface bit rate is 10Gbps or less.
Analysis of QL indicated in received Ethernet signal. An alarm is raised on
missing QL indications.

ESMC messages capture
ESMC messages can be captured and exported in a Wireshark
compatible format.
Timing master/slave
Each port of the Ethernet interface can act as a timing master or a timing
slave independently.
Supported modes: Multicast (native PTP) and Unicast (G.8265.1). When acting
as master in Unicast (G.8265.1) mode, one slave is accepted at a time, other
slaves are ignored. If the slave requires 32, 64 or 128 Sync messages per
second, the IEEE 1588-2008 paragraph 7.7.2.1 concerning 90% confidence
interval is not followed.
