10 APPLICATIONS GUIDE – Hints & Ideas
Of course we hope that you will (eventually) read through the other sections of this manual –
we give you a lot of information about audio coding technology and lots of information on how
and when to use the different coding modes. However, here we have included the following
informational guide to get you started.
10.1 Xstream Versatility – types of dial-up connection and modes
The Xstream is the most versatile codec platform on the market at this time, communicating
with a variety of devices in several ways. In this section, we'll give a review of the different
modes available when on ISDN, illustrating the various capabilities of the unit.
First, let us look at a matrix of the Xstream's abilities:

The matrix shows the appropriate Mode to use when placing outbound calls, however the unit
can receive all these same call types, of course. Since the Zephyr mode supports a number of
different codecs (for differing user requirements, as well as compatibility with other codecs) the
Xmt, RCV, and Sample settings must be configured, as well as using the correct call type when
using this mode.
