About this Guide
The Cisco VG248 Analog Phone Gateway Hardware Installation Guide provides the information you need to install the Cisco VG248 Analog Phone Gateway (VG248) on your network.
Network engineers, system administrators, and telecom engineers should review this guide to learn the steps required to properly set up the VG248 in the network.
The tasks described in this guide are considered to be administration-level tasks. Because of the close interaction of the VG248 with Cisco CallManager and analog telephony systems, these tasks require that you are familiar with these systems as well.
Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. (To see translations of the warnings that appear in this publication, refer to the appendix "Translated Safety Warnings.")
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
This guide provides the required steps to install the VG248. You must use this guide in conjunction with the Cisco VG248 Analog Phone Gateway Software Configuration Guide to get the VG248 up and running on your network.
Because of the complexity of an IP telephony network, this guide does not provide detailed information for required procedures performed on other Cisco or third-party devices. Refer to the documentation provided with these systems for installation and configuration instructions.
Table 1 provides an overview of the organization of this guide.
