The 4215 Dual CSU/DSUTM is the world’s first dual CSU/DSU. The electrical interface on the DTE port is selectable as RS-449/EIA-530 or V.35. Data traffic can be Frame Relay, PPP, Cisco HDLC, or Transparent bit-based protocol.

The unit is SNMP-manageable (supports SNMPv3) in-band when using Frame Relay, PPP, or Cisco HDLC protocols, 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. 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.
