How Digital Telephone IP Adapter units work
There are two major components to the Digital Telephone IP Adapter units.
They are:
1. the Digital Telephone Internal or External IP Adapter unit located at the
remote location
2. the RLC located on the host PBX
These two components, along with the connection options described on page 35,
extend the host PBX services to a remote user.
