Cisco 4-Port Clear Channel T1/E1 High-Speed WAN Interface Card

HWIC-4T1/E1

Features At-A-Glance

  • 4 ports of RJ-48 connectors
  • Cisco IOS® Software configurable for T1 or E1 operation
  • Integrated CSU/DSU per port
  • Balanced or unbalanced E1 termination in the same module
  • E1 unframed and framed modes (G.703 and G.704)
  • Independent clocking for each port
  • Multilink PPP or Multilink Frame Relay (FRF.16) for T1/E1 ports on the same module and across different modules

Key Benefits

Reduced Footprint

If you are using multiple 1- or 2-port T1/E1 modules for n x T1/E1 connectivity, you can now replace the modules with a single Cisco 4-Port Clear Channel T1/E1 HWIC, and you can make the HWIC slots available for other interfaces and services. If you use a single T1/E1 today and plan to scale up to 4 T1/E1 modules in the future, you can install the 4-port HWIC today and turn on the additional T1/E1 ports as you need them.

Deployment Flexibility

The Cisco 4-Port Clear Channel T1/E1 HWIC is software-configurable between E1 or T1 operation, balanced or unbalanced E1 termination, and CSU/DSU. You no longer need to buy a specific module for T1 support and then another card for E1 connectivity. If you have branch offices across the world, ordering, inventory and management are much simplified.

Reliability

Integrating the external E1/T1 terminating device (CSU/DSU) increases the overall system reliability. Possible points of failure are reduced by eliminating the second power supply, additional fans, extra cabling, and other equipment that accompany a "two-box" solution. This increase in reliability allows service providers to more easily and cost-effectively meet the requirements of their customers' service-level agreements (SLAs) and offers enterprises maximum equipment uptime.
