The updated Cisco T1 data service unit/channel service unit (DSU/CSU) WAN Interface Card (WIC) is an integrated, fully managed DSU/CSU for T1 or fractional T1 service. The WIC-1DSU-T1-V2 is an updated version of the WIC-1DSU-T1, offering additional supported features with the same performance
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
