Basic Settings
Clock
All E1/T1/J1 spans generate a clock signal on their transmit side. The
parameter determines whether the clock signal from the far end of the
E1/T1/J1 is used as the master source of clock timing. If the far end is
used as the master, the gateway system clock will synchronize to it.
• Master:
The port will never be used as a source of timing. This is
appropriate when you know far end should always be a slave to you.
• Slave: The equipment at the far end of the E1/T1 link is the preferred
source of the master clock.
