Installing and Operating BayStack AN and ANH Routers

56/64K DSU/CSU Interface
The AN/ANH supports direct synchronous access to either a 56 Kb/s dataphone
digital service (DDS) or 64 Kb/s Clear Channel dedicated services using an
optional 56/64K DSU/CSU adapter module.
Table C-9
lists the 56/64K DSU/CSU interface pin assignments.
FT1/T1 DSU/CSU Connections
The AN/ANH supports the conversion of data (HDLC protocol) from a T1 line
using an optional FT1/T1 DSU/CSU adapter module. The integrated DSU/CSU
functions allow you to connect directly to the T1 network, as opposed to
connecting via an external adapter. This solution reduces equipment costs and
simplifies connection to a T1 carrier.
The AN/ANH FT1/T1 DSU/CSU implementation supports dynamic
reconfiguration, fractional T1 loopback, facility data link (FDL) functions, and an
integrated bit error rate test (BERT) line tester. Configuring WAN Line Services
describes these services and how to configure them for connection to a T1
network.
