NM-HDV2-1T1E1产品简介

Readers of this document should have basic knowledge of Cisco Systems IOS voice gateways, and experience operating and administering them.

This document assumes that the reader already has an operational voice router configuration, and that both inbound and outbound call scenarios function as expected for basic TDM-to-IP voice calls. This document assumes that the VGW has any combination of BRI, PRI, analog or digital E&M, analog or digital FXO, analog or digital FXS, analog CAMA, and analog DID voice-ports installed on voice Network Modules which utilize Texas Instruments (TI) C5510 DSP technology.
