Table 28: Digital Hardware Configuration Parameters: E1 - MFC/R2

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.
