2 port channelized T1/E1 and PRI HWIC
The Cisco E1/T1 ISDN PRI HWICs are software-configurable between E1 or T1 operation, balanced or unbalanced E1 termination, and CSU/DSU. Customers no longer need to buy a specific module for T1 support and then another card for E1 connectivity. In addition, the same modules provide for balanced (120-ohm) and unbalanced (75-ohm) E1 termination. Table 1 lists available cable adaptors.
Support for G.703 Unstructured E1 Signaling
ITU signaling standard G.703 was previously available only on Cisco midrange routers through the voice/WAN interface card (VWIC-xFT-G703), which did not support data PRI. Framed E1 (G.704) is also supported for international customers without G.703 service.
High-Density PRI Connectivity Options
With the new 8-port Channelized T1/E1 and ISDN PRI modules, the Cisco 3800 Series provide superior performance and port density needed for WAN gateways of small enterprises.
Increased Manageability and Troubleshooting
Critical loopback support makes the Cisco Channnelized T1/E1 and ISDN PRI Modules easy to manage. Both models can internally loop back the onboard framer chip toward the interface, thus eliminating the need for an external loopback plug. Local, remote, line, and payload loopbacks, complement the management features of the Cisco Channelized T1/E1 and ISDN PRI Module.
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 provides enterprises with maximum equipment uptime.
The Cisco Channelized T1/E1 and ISDN PRI High-Speed WAN Modules combine multiple T1/E1 WAN connectivity-Channelized T1/E1 and ISDN Primary Rate Interface (PRI), in the same card. With flexible WAN connectivity options, together with integrated routing, security, voice, and wireless capabilities, Cisco Integrated Services Routers can meet every need of enterprise-class branch offices today and in the future. The integrated channel service unit/data service unit (CSU/DSU) function allows customers to consolidate customer premises equipment (CPE).
The 1- and 2-port Channelized T1/E1 and ISDN PRI HWICs are updated versions of the E1/T1 ISDN PRI network modules, with the same functions and performance in a compact form factor of HWIC. You can save the network module slots for other LAN/WAN connectivity, and your deployment flexibility is greatly enhanced.
