Kentrox Data Service Unit/Channel Service Units (DSU/CSUs) are renowned for their performance, reliability, and broad range of features. DSUs are WAN access devices that combine the data formatting of a DSU with the FCC-mandated line protection and diagnostic capabilities of a CSU. Basic DSU/CSUs are ideal for networks where there are no requirements for remote diagnostics or any form of centralized management. Managed DSU/CSUs provide a way for an IT manager to view many remote devices from a centralized monitoring console. Managed DSU/CSUs can also generate alarms when certain network events occur, and forward those alarms to the management console to assist in network troubleshooting. A managed DSU/CSU typically includes an SNMP-compatible agent and supports standard interface MIBs.Although slightly more expensive to purchase than a basic DSU/CSU, a managed DSU/CSU can significantly reduce service outage time because of its diagnostic capabilities.ADC Kentrox Part Number: NCCSDHT4AB
