6AM/12AM Modules of H3C Series Routers
I. Preface
From the perspective of services implementation, AM (Analog Modem) is similar to the combination of asynchrony serial port and analog modem. Most of configuration commands for asynchrony serial port and modem can be run directly on AM interface. AM interface can be considered as a special asynchrony serial port for configuration.
AM interface fulfills the dial-in/call out function of analog dial-in users, with up to 56K bit/s rate supported (using V.90 recommendation).
II. 6AM/12AM Modules
1.Introduction to Modules
AM interface fulfills the dial-in/call out function of analog dial-in users and supports such protocols as ITU-T V.32 and V.90 Modem, with up to 56K bit/s rate (using V.90).
R2600/R3600 series modular router supports two models of AM modules: 12AM and 6AM, where
