7-IWay Hopper
Chapter 1 - Introduction
Welcome to the world of ISDN communications. You have acquired one of the
finest ISDN terminal adapters (TAs) available today, model(s) MT128ISA-SD/SV
and MT128ISA-UD/UV from Multi-Tech Systems.
The proliferation of PCs and LANs with bandwidth-intensive applications has
generated a powerful demand for high-speed connections. The worldwide stan-
dardization of ISDN, combined in many countries with its growing availability and
falling cost, make it a natural choice for enhancing data throughput. Terminal
adapters provide high-performance solutions for Internet access, file transfer,
remote access service (RAS), and running existing modem applications through
the ISDN network.
1.1.1 Product Description
The MT128ISA-xx is an internal PC card for IBM personal computers; and fits
into a full-or half-sized expansion slot. There are two ISDN interface options, ST
and U. If you purchased the ST interface adapter (MT128ISA-SD/SV), you need
an ISDN NT1device connection to the ISDN switch. If you purchased the U
interface adapter (MT128ISA-UD/UV), it can directly connect to the ISDN switch
(Figure 1-1).
