1016 Category 3, Type B - Dedicated Telegraph BSA

Category 3 - Dedicated Basic Serving Arrangement

A dedicated BSA provides an ESP with a dedicated point-to-point connection 
through the network.  This category of serving arrangements are available 
full-time so that individual calls are not set up and taken down.  This BSA 
is capable of supporting analog or digital signals at various transmission 
rates.  The transmission interface may be 2-wire or 4-wire, or derived from a 
variety of multiplexing alternatives (e.g., DS-1 or DS-3).  It is also capable 
of providing supervisory signaling in some configurations. 

Route diversity may be available with this serving arrangement.
