The Nortel ATA M3900 Module is a Nortel Meridian Analogue Terminal Adapter (ATA) that allows for connection of an off-the-shelf analogue device, such as fax machine, laptop or PC, to be connected to the M3902, M3903, M3904 and M3905 digital telephones. 

The Nortel ATA negates the requirement for separate analogue lines to be run to the desk top or for separate analogue lines cards to be installed to the system. It also provides an economical solution for connecting analogue devices and in addition the ATA can receive and pass Dual Tone Multi-Frequency (DTMF) or dial pulse and supports modem connection rates of up to 33.6kbps.
