MG-IP TDM Over IP Gateway Reference Manual
18
In PTMP topology, the aggregator is always the master, while in PTP topology, one MG-IP unit is the
master and the other is a slave (this is arbitrarily selected).
Adaptive Timing Applicaton Configuration
The folowing sections describes possible MG-IP adaptive timing application configurations (adaptive
timing is always set on the slave).
Adaptive Loopback Timing Application Configuration
In adaptive loopback timing mode (see Figure 10), the master is configured to loopback timing only if
all ports are locked to the same source clock (this is the customer’s responsibility and is only applicable
to the MG-IP-4).
The slave is configured to recovered timing.

Adaptive Line Timing Application Configuration
In adaptive line timing mode (see Figure 11), the master is configured to line timing, while the slave is
configured to recovered timing.
