ISDN TA/V
4.1 Preparing for Installation
In order to install and use your ISDN TA/V, you’ll have to make sure you
have all the proper equipment, cables, and connectors. These requirements
may vary depending on your particular application
4.2 Connecting a Computer
An ISDN TA/V can only receive data from your computer via a serial port
connection. On most IBM or compatible PCs , this would be a D-shell male
connector, V.24 RS-232 serial port, with 9 pins (DB9). Connecting an Apple
®
Macintosh
®
computer requires an available 9-pin serial port. Most PCs have
only one serial port, which is likely to be labeled
COM1
.
Many devices other than an ISDN TA/V can be connected to a serial port, for
example a serial printer, mouse or graphics plotter. If your PC has only one
serial port, and this is already supporting an external device, you can swap
between the ISDN TA/V and the other device as required. However, if you
prefer to use both devices without the interruption of plugging and
unplugging cables, ask your PC supplier to install a second serial port.
4.3 Connecting an Alternate DTE Device
This must be equipped with either a V.24/V.28, X.21 (V.11) or V.36 serial
port, for connecting to the DTE interface of the ISDN TA/V.
4.4 The CONTROL Port Connection
Optionally, an asynchronous terminal can be connected to the
CONTROL
port of the ISDN TA/V to enable you to pass AT commands to the ISDN
TA/V when using a synchronous transmission format over the DTE interface
link, or to gain access to the unit’s management interface facilities.
The communications format of any device connected to the
CONTROL
port
must be set to 8N1 (8 data bits, no parity, 1 stop bit), running at
9600 bps.
