Master Mode emulates a SyncE Master clock device and slave mode emulates a SyncE Slave clock device.
Both modes operate out of the Ethernet test port (100/1000BaseT, 100/1000BaseX, or 10GE) and can use an
internal or external reference clock.
SyncE Master-Emulation Mode
l
Synchronous Ethernet: Enabled or Disabled.
l
Emulation Mode : Select Master or Slave emulation mode. In Master mode, the unit uses the TX
Clock Source reference clock to provide SyncE clock on the Ethernet interface (10/100/1000T and
100/1000BaseX or 10GE port). In Slave mode, the unit recovers SyncE clock from the Ethernet inter-
face (10/100/1000T and 100/1000BaseX or 10GE port).
l
TX Clock Source (Master Mode): Select between an internal or external clock source. This clock is
used as a reference clock for SyncE Master operation.
l
Measurement Clock Reference (Slave Mode): Select between an internal or external clock source.
This clock is used as a reference clock for SyncE Master and for SyncE Slave Wander Meas-
urement.
Possible Internal Clock sources: Internal Clock (+/-3.5ppm accuracy), Internal GPS 1 PPS
(Requires GPS option and Antenna), Internal Atomic 1 PPS (Requires High Precision Atomic Clock
option).
l
Possible external clock sources: 1.5444MHz,1.544Mbps, 2 MHz, 2Mbps (E1 signal), 10MHz,
25MHz, 125MHz or External1 pps. The external clock source is connected to the SMA port on each
