NT5D12 switch settings

The NT5D12 card is equipped with 6x2 sets of DIP switches for trunk
parameters settings for port0 and port1 respectively. Additionally, the
NT5D12 card is equipped with one set of four DIP switches for the Ring
Ground setting and one set of eight DIP switches for the D-channel Handler
parameters setting.
The DIP switches are used for setting of default values of certain
parameters. The general purpose switches are read by the firmware which
sets the default values accordingly.
The following parameters are being set by the DIP switches. Factory setups
are shown in bold.
General Purpose Switches
A per-trunk set of four DIP switches provides the default setting for
operational modes. Switch set S9 is used for Trunk 0. Switch set S15 is used
for Trunk 1. Refer to
