Management Full management features:Configuration - Capability for remote configuration via Telnet from Cisco IOS CLI.Monitoring - Router and DSU/CSU are manageable as a single SNMP entity; extensive DSU/CSU statistics are provided by the Cisco IOS CLI.Troubleshooting - Extensive loopbacks (including manual button for network line loopback), bit error rate tester (BERT) test patterns, alarm counters, and performance reports, all of which are accessible from Cisco IOS CLI. LEDs for carrier detect, loopback, and alarm functions.Convenient Telnet or Secure Shell (SSH) Protocol connection to the router eliminates the need for out-of-band management of external DSUs/CSUs
