About the 7123 SNMP DSU/CSU
System Overview
The 7123 SNMP DSU/CSU provides an interface between the T1 digital network
and the customer premises equipment, converting signals received from the DTE
(Data Terminal Equipment) to bipolar signals that can be transmitted over T1 lines.
The 7123 SNMP DSU/CSU offers these features:
Auto-Sensing 10/100BaseT Port.
an Ethernet LAN.
SNMP (Simple Network Management Protocol) Management.
