QoS Measurements
Note: For Dual Port topology in One-Way P<m>  P<n> , these settings are
coupled.

Latency/Jitter check box, when selected (default), allows latency/jitter
configuration and monitoring.

Measurement Mode :
One-Way
measurement provides the delay measurement for each
direction independently on a specific port. This mode requires an
external 1PPS clock source (see
Clock
on page 167); the
LOPPS-L
alarm is displayed reporting its status (refer to Clock on page 397).
On the 88260 module dual port topology, both ports must be on the
same transceiver system since a TA-SYNC is required for the 1PPS
clock.
Round-Trip Latency measurement provides the total delay
measurement for both directions on a specific port.
One-Way P<m>

P<n> provides the delay measurement of
each direction independently between two separate ports of a
single module (Dual Port test). Only available when the rate and
framing parameters (Frame Format, Network Layer, and Transport
Layer) are the same on both ports.

Measurement Role
determines whether the eCPRI node acts as
the Sender (default) or the Receiver .
Remote Status
indicates whether a configuration mismatch exist
between each end based on the one-way delay messages that are
exchanged:
