Cisco HWIC-4T1/E1 WAN Interface Card Product Details
Cisco HWIC-4T1/E1 WAN Interface Card
The Cisco HWIC-4T1/E1 WAN Interface Card provides n x T1/E1 connectivity in a compact form factor and reduces deployment and management costs for the Cisco Integrated Services Routers. As more data and voice services are enabled in branch offices, the demand for WAN bandwidth increases accordingly. Multilink Point-to-Point Protocol (PPP) and Multilink Frame Relay enable customers to scale their leased lines from single T1/E1 to multiples of T1/E1, adding bandwidth as their needs increase. The Cisco HWIC-4T1/E1 WAN Interface Card integrates four (4) T1/E1 ports in a singlewide HWIC to facilitate n x T1/E1 connectivity in a compact form factor.
With the Cisco HWIC-4T1/E1 WAN Interface Card with integrated channel service unit and data service unit(CSU/DSU), you can consolidate customer premises equipment (CPE). The Cisco HWIC-4T1/E1 WAN Interface Card modules support balanced and unbalanced E1 connectivity and conform to G.703 and G.704 standards for unframed and framed E1 modes. The module supports both T1 and E1 modes, selectable by software configuration.
What It Is And Why You Need It:
- 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
|Dimensions (H x W x D)||0.75 x 3.08 x 4.74 in. (1.91 x 7.82 x 12.04 cm)|
|Weight||0.20 lb (0.09kg)|
to 104°F (0 to 40°C)
14 to 131F (–10C to 55C when installed in the MWR-2941-DC)

|Relative Humidity||5 to 95% noncondensing|
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 HWIC-4T1/E1 WAN Interface Card, 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.
The Cisco HWIC-4T1/E1 WAN Interface Card 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.
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 costeffectively meet the requirements of their customers' service-level agreements (SLAs) and offers enterprises maximum equipment uptime.
