Benefits of an Integrated, Fully Managed Solution
The T1 DSU/CSU WIC enables trouble-free Internet/intranet access with a simple, fully managed, integrated solution
from a single vendor. Its ease of configuration and management differentiates it from external or separate DSUs/
CSUs. Full management capability and modularity differentiates the T1 DSU/CSU WIC from other integrated
router-DSU/CSU solutions, which typically have limited management and fixed configuration. This card delivers
flexibilityand investment protection,extending thegrowing familyof WICs forCisco 1700Series, 2600Series, 3631,
and 3700 Series routers and Cisco ICS 7750 Software.
Reduced Deployment, Management Time, and Costs
Ease of configuration and management—The Cisco T1 DSU/CSU WIC simplifies tasks in the following ways:
• Easily configures via Cisco IOS Software initial setup, a utility that prompts a series of basic configuration
questions upon router startup.
• Allows simplified remote and local configuration, management, and troubleshooting of the DSU/CSU from Cisco
IOS CLI:
– Using the familiar Cisco IOS CLI eliminates the need to learn or use command syntax for an external DSU/
CSU
– Convenient Telnetor Secure Shell (SSH) Protocol connection to the router eliminates the need for out-of-band
management of external DSUs/CSUs
– CiscoIOSCLI providesextensive DSU/CSUstatistics (such as24-hour history)and troubleshooting capability
(such as DSU/CSU self test, loopbacks, DSU/CSU reset, alarm counters, and T1 statistics)
• Offers simplified SNMP management, with router and DSU/CSU managed as a single SNMP entity through
CiscoWorks/CiscoView. The Cisco T1 DSU/CSU WIC SNMP agent supports the standard MIB II, Cisco
integrated DSU/CSU MIB, and T1 MIB (RFC 1406). All T1 performance statistics can be monitored. The router
also generates the appropriate SNMP traps in response to DSU/CSU alarms.
• An end-user-initiated manual loopback button allows users at remote sites to easily initiate a T1 network line
loopback by pushing a recessed button on the WIC front panel without having to access the router via a console
port or Telnet.
• Provides LEDs for carrier detect, loopback, and alarm, allowing for quick troubleshooting.
Physical convenience—No additional space is needed because the Cisco T1 DSU/CSU WIC is inserted into the router.
This integrated solution eliminates the need for a separate serial cable, reducing deployment time and cost.
High reliability—The integrated DSU/CSU reduces the number of components in the network, leading to higher
reliability. The serial cable that connects a router serial port to an external DSU/CSU is eliminated. The integrated
DSU/CSU is powered from the router, eliminating the power supply for an external DSU/CSU. The Cisco 2600XM,
3600, and 3700 series are all available with redundant power systems, which cover the integrated DSU/CSU.
Flexibility and Investment Protection
The Cisco T1 DSU/CSU WIC extends the Cisco commitment to providing customers with maximum flexibility and
investment protection through modular WICs that are supported on award-winning router platforms. When WAN
bandwidth requirements or service provider pricing change, users can easily change WAN services either by changing
