Telos Zephyr Xstream - Manual (Page 14)

USER’S MANUAL
Section 1: QUICK RESULTS 2
What you need before you start…
There are two categories of items you need: First, the equipment to connect your Zephyr
Xstream to the audio equipment and the ISDN circuit; second, some information that should
have been provided to you by the person who provided your ISDN.
1.1 Connections Preview
ISDN Connections
All of the connection cables have telephone‐type modular connectors and come packaged with
your Zephyr Xstream.

IMPORTANT TIP!
An RJ-11 style 6-position plug can be inserted into the center of an RJ-45 style 8-position
jack, if the Telco installed an RJ-45 style jack for your U Interface ISDN line (in the USA or
Canada).
1. In the USA & Canada you will be using the Zephyr Xstream’s built‐in NT1.
Cable required: A standard telephone‐type modular cable that fits into the
smaller, RJ‐11 style jack on the Zephyr Xstream. The other end of this cable
plugs into the jack provided by the Telco.
2. OR‐Your telephone company (Telecom) has provided an NT1. This is nearly
always the case outside of the USA & Canada. Cable required: A large,
modular cable with eight wires that fits into the upper (larger, 8 pin RJ‐45
style) jack on the Zephyr Xstream and a jack on the NT1 that is labeled
“Terminal” or “S/T”. The other end of this cable plugs into the NT1, or into
the jack wired by the Telco. Your NT1 should have been wired to the ISDN
line by your Telco.
Audio connections
You want to hear something, don’t you? Connections are needed for sending audio to the
remote location and receiving audio from it. You will need to provide the appropriate cables. For
connection to the Zephyr Xstream, the two send cables must have either male XLR connectors
or ¼ inch plugs (Zephyr Xstream accepts XLR, and both Tip/Ring (TR) unbalanced and
Tip/Ring/Sleeve (TRS) balanced ¼ inch connectors). The two receive cables must have female
XLR connectors. The termination on the other side of these cables depends on your equipment.
You may choose to use headphones to listen to the receive audio; in this case you will not need
receive cables.
