Introduction
1.1 An Overview of the ACCURA External ISDN TA
The ACCURA External ISDN TA is an external ISDN digital
modem (or Terminal Adapter) for connection with digital
telephone services from your local telephone company.
The ISDN TA provides high-speed access to the Internet,
corporate Intranet and online information services. It allows
data transmission at speeds of up to 128 Kbps. In addition to
the high-speed data access, the ISDN TA also supports two
analogue ports for connecting traditional analogue devices
such as a telephone, fax machine, answering device or modem
to an ISDN network.
Installation is relatively simple. You need to have ISDN
service from your phone company and an ISDN jack (S/T
interface) to plug into. Then you connect the power cable,
ISDN cable, and optional telephone equipment. Then you run
our installation software before placing your first call.
