DCSU 2911 Dual Channel Service
Unit
The DCSU 2911 is an AS2000 application module that provides two
network ports—E1 or T1, depending on which connector interface
module (CIM) is used. The E1 configuration supports either 75
Ω
BNC or 120 Ω RJ-48 connectors. The T1 configuration supports 100 Ω
RJ-48 connectors. This application module can be managed using
the Craft Interface directly, through the NCM 2000 controller
module, or with the optional Node Manager software.
