In unchannelized (also called clear channel) operation, each E/T interface port provides a single high-speed data channel. Each port can be configured to use any portion of the E/T available bandwidths. The maximum E bandwidth is.86 Mbps; the maximum T bandwidth is.76 Mbps.

2 Software and Hardware Compatibility Chapter 8-Port Unchannelized E/T Line Card Overview The line card provides Cisco series routers with eight E or T high-density unchannelized interface ports. The line card: Supports eight multiport T or E copper interface terminations Provides a solution for service providers if a fiber interface is unavailable Provides Internet service providers with the means to interface with existing copper Internet Protocol (IP) leased-lines Supports the High-Level Data Link Control (HDLC), Frame Relay, and Point-to-Point Protocol (PPP) encapsulations If you are a registered Cisco.com user, see Feature Navigator for supported features. Software and Hardware Compatibility To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether line cards within a system are compatible, but does provide the minimum Cisco IOS requirements for individual hardware line cards, modules, or options. Note Access to this tool is limited to users with Cisco.com login accounts. To access Software Advisor, click Login at Cisco.com, type Software Advisor in the SEARCH box, and click Go. Click the link for the Software Advisor tool. Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.

7 Chapter 8-Port Unchannelized E/T Line Card Overview Cables and Connectors Cables and Connectors External network connections to the 8-port unchannelized E/T line card are made through the BNC connectors mounted on the rear of the Cisco chassis, using 7-ohm coaxial cable (Figure -). The approved cables for use with the 8-port unchannelized E/T line card are cables conforming to WECO standards 78A, 7A, or 7D. Use cable lengths up to ft (7.6 m). 7A cables can be used with lengths up to ft (68.8 m).

Line card slots (top) to (bottom) Also see Appendix A, Cisco Extender Card Information for information about the extender card which must be used with the 8-port unchannelized E/T line card in the Cisco chassis. All Cisco cards connect to a backplane in the center of the chassis, and require extender cards to deliver the alarm, BITS clock, and DS signals to the rear of the chassis to make them accessible. The Cisco alarm extender card and T/E extender card extend and terminate these signals. Go to Chapter 6, Preparing for Installation to begin the installation or replacement of the line card.
