A P P E N D I X D Installing the Virtual Private Network Module This chapter describes how to install the Virtual Private Network (VPN) module in your Cisco 1760 router. Before You Begin This section describes important safety information and the tools required to install the VPN module. Read this section before installing the VPN module in a Cisco 1760 router.
Appendix D Installing the Virtual Private Network Module Before You Begin Safety Warnings Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Warning Do not touch the power supply when the power cord is connected.
Appendix D Installing the Virtual Private Network Module Before You Begin Warning Only trained and qualified personnel should be allowed to install or replace this equipment. Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first.
Appendix D Installing the Virtual Private Network Module Installing the VPN Module in a Cisco 1760 Router Caution To avoid damaging the equipment, periodically check the resistance value of the antistatic strap.

A P P E N D I X E Installing the Echo Canceler Expansion Modules on Cisco Interface Cards This chapter provides information about the hardware-based echo canceler expansion modules that are available on the enhanced multiflex trunk interface cards on the Cisco 1760 router.
Appendix E Echo Echo occurs when the speech energy being generated and transmitted down the signal path is coupled into the receive path from the far end. This causes a speaker to hear the sound of his or her own voice, delayed by the total echo path delay time. In a traditional voice network, voice can reflect back, but it usually goes unnoticed because the delay is so low. In a Voice over IP (VoIP) network, echo is more noticeable because packetization and compression contribute to delay.
Appendix E The following echo canceler expansion modules are available for voice-only support on the 1-port RJ-48 multiflex trunk T1/E1 (VWIC2-1MFT-T1/E1) and on the 2-port RJ-48 multiflex trunk T1/E1(VWIC2-2MFT-T1/E1) interface cards on the Cisco 1760 router.
