Basic Setting

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 PBX system clock will synchronize to it.

• Master: The port will never be used as a source of timing. This is

appropriate when you know the far end should always be a slave to

you.

• Slave: The equipment at the far end of the E1/T1/J1 link is the

preferred source of the master clock.
