Key Benefits
Enhanced Flexibility
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,
