Table 27: 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.

ANSI & CHINA Format: decimal number or XXX-XXX-XXX.
Destination point code is the address to send the message to, always be
provided by the operator/ISP.

ITU Format: decimal number.

ANSI & CHINA Format: decimal number or XXX-XXX-XXX.
Network Indicator (NI) should match in nodes, otherwise it might cause
issues. Users can select "National", "National Spare", "International", or
"International Spare". Usually "National" or "International" is used.
The line build-out (LBO) is the distance between the operators and the
PBX. Please use the default value 0dB unless the distance is long.
Configure the RX gain for the receiving channel of digital port. The valid
range is from -24dB to +12dB.
Configure the TX Gain for the transmitting channel of digital port. The
valid range is -24dB to +12dB.
