The 4210 CSU/DSU is an access device with single DTE port connection
to an external router configured as Frame Relay, Cisco HDLC, or
PPP.
The unit is SNMP-manageable (supports SNMPv3), offers menu-driven configuration, includes
comprehensive diagnostics, and complies with industry and regulatory
standards. A Troubleshooter feature includes LMI conditioning, link-based
testing, and in-band management for Frame Relay and Cisco HDLC.
These tools simplify installation and troubleshooting, thereby reducing
network downtime and remote technician costs.
User level security lets you define multiple access levels to the device
configuration menus. An internal clock acquired automatically from an RFC868 time
server keeps the unit synchronized with your network.
