M3900 Series Meridian Digital Telephones Description, Installation and Administration
Analog Terminal Adapter (ATA)
The AnalogTerminal Adapter (ATA) lets you connect an analogdevice such
as a fax machine or modem to your telephone. You can have simultaneous use
of the telephone and the analogdevice. The ATA is available for the M3902,
M3903, M3904 and the M3905 models.
Computer Telephony Integration Adapter (CTIA)
The Computer Telephony Integration Adapter (CTIA) along with the TAPI
software provides an interface to connect a Personal Computer (PC) to the
M3900 telephone.
An RS-232C cable is required to connect the PC to the CTIA. The CTIA
connects to the M3900 Series telephone through the Accessory Connection
Module (ACM). The CTIA is a small cartridge accessory and can be inserted
into either the small or large footstand opening.
The CTIA is powered through the ACM. The ACM receives power through
the telephone via the telephone line cord which is connected to a Teladapt
wall transformer power supply (see Figure 13 on page 93). Check with your
Nortel Networks distributor for the recommended wall transformer for the
M3900 accessories. Install the Accessory Connection Module (ACM) into
your M3900 Series Meridian Digital Telephone (refer to the ACM
Installation Sheet) before you install your CTIA.
The CTIA cartridge provides the user:
• connectivity to the PC
• voice call control
Telephone Application Programming Interface
(TAPI) software
TAPI software accompanies your CTIA Cartridge. The TAPI software allows
a user to program telephone-line-based devices to work independently from
their computer or other devices.
