Configuring a Series 5000 Half-Router
Before programming, a Router 5000 uses its default communications parameters,
which define a simplified single-ended mode 78 kbps channel. Like the Router
5000, an FT Router 5000’s default communications parameters define a
simplified single-ended mode 78 kbps channel – a TP/FT-10 channel. For the
