PLL Clock Sync
ISDN device clocks must be synchronized. Some PBXs are Masters, that is, they
deliver the clock signal. In this case, the Gateway should be set to Slave.
Otherwise, the Gateway should be set to Master.
Remote Device
Define if the Gateway is connected to a PBX or to an operator’s network.
Line Coding
A line code is a code chosen for use within a communications system for
transmission purposes. Select the line coding that is used by the remote device.
Framing Type
ISDN transmissions are framed using one of several existing framing methods,
for example, Cyclic Redundancy Check 4 (CRC-4). Select the framing type that
is used by the remote device. CRC-4 support is required for all network switches
in Europe. However, some older switches including private branch exchanges
(PBXs) do not support CRC-4.
