DSU IV ESP  
All-Rate DSU with SNMP and Dial Backup  
®
The ADTRAN DSU IV ESP is an all-rate  
data service/channel service unit (DSU/CSU)  
with an integral SNMP (simple network  
management protocol) agent and optional  
dial backup (DBU) capabilities. It provides  
an interface between digital data service  
(DDS) or 4-wire Switched 56 and the cus-  
tomers data terminal equipment (DTE). The  
DSU IV ESP provides access to traditional  
dedicated point- to-point, multi-point, or  
Frame Relay services.  
The Dial Backup (DBU) feature of the DSU  
IV ESP allows automatic or manual switched  
backup in the event of a dedicated line failure.  
The addition of DBU is accomplished through  
a family of plug-in ESP DBU cards. There are  
three versions of ESP DBU cards available for  
the DSU IV ESP: ISDN,
