Async MODEM Module Installation
The
chapter introduces async analog Modem module and now there are 16-port(NM-6AM)and
12-port(NM-12AM)async analog Modem module.
Introduction to Async Modem Module
Information of async Modem Module
NM-6AM module ,NM-12AM module are 6-port and 12-port analog MODEM modules. The AM is Analog Modem.6-port async analog Modem Module uses a 6-RJ11 interface to connect to 6-port Modem.12-port async analog Modem module uses two 6-RJ11 interfaces to connect to 12-port Modem.
NM-6AM&NM-12AM modules are adapted to D-Link2630,D-Link2640,D-Link2641,D-Link2650,D-Link3660 routers.
The
module port supplies RJ11 common telephone interface and 6-port/12-port RJ11
interface.
The index of the main performance of NM-6/12AM :
1. Supply up to 6/12 RJ11 interface. Support 56Kbps。
2. Accept&reduce the analog signal and send the disposal data to router on the bus or send the data transmited by the main computer to PSIN on the telephone interface after reducing .
