Table 35: Digital Hardware Configuration Parameters: E1 - SS7

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 link is the preferred
source of the master clock.
Select ITU, ANSI or CHINA.
Originating point code is used to identify the node originating the message,
always provided by the operator/ISP.

ITU Format: decimal number.

provided by the operator/ISP.

ITU Format: decimal number.
