E1 CSU/DSU Interface Module
An E1 CSU/DSU Interface Module provides a direct E1 or fractional E1
connection to a Passport E1 Function Processor, or any other compatible
device. This E1 connection provides a larger communication bandwidth than
the serial connection.
There are two models of E1 CSU/DSU Interface Modules available:
•
The E1 CSU/DSU for120 ohms (NTAU96AA)
•
The E1 CSU/DSU for 75 ohms (NTAU97AA)
Both Port 2 and Port 3 can support either E1 CSU/DSU module.
Note:
Determining the proper module to use (75 ohms/120
ohms) will depend on the network requirements of the
location of the Passport 4400.
