Modem Simulator
This Wiki Page describes how to use a NetModule Wireless Router as replacement for legacy dial in / dial out connections based on analog or gsm modems.
We support the Hayes AT Command set on the serial interface and behave like normal router
You can easily replace your old Modem with an the NetModule Router. There is also no need to configure the attached device as you can prepare the NetModule Router accordanly.
Prerequierments
- NetModule Wireless Router with a Serial Interface (integrated or as an extension)
- NRSW 4.1.0.100 or newer
Concept
The Modem Emulator will only replace the AT Command Set on the serial side. The Communication between the NB1600 and another Endpoint will be done as a transparent tcp Connection.
This way you can provide the old legacy functanality over modern IP Connections. Depending on your infrastracture you could secure your communication with a VPN Layer or work straight with Public IP Adresses.
Adressing
An important Part on the Dial-In/Dial-Out Installations is the addressing of the Endpoints. The old addressing concept were based on phone numbers. With the Modem Emulator the Adresses will switch on an ip-address/port based addressing.
But for backward compatibiliy we integrated a Phonebook Feature, so that you can keep the old phone-number based addresseing and we woll resolv them into ip-address/ports.
