will need to provide the appropriate cables. For connection to the Zephyr, the two
send cables must have male XLR connectors and the two receive cables must have
female XLR connectors. The termination on the other side of the 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.

Information on your ISDN line

Zephyr needs to know some things about your ISDN line to work properly. Your ISDN
circuit consists of two, digital "B channels". Just like a regular telephone line, these
channels have telephone numbers so that you can send and receive calls. The Zephyr,
as with most ISDN equipment, refers to these channels are "lines" Unlike regular
telephone lines, both lines may have the same telephone number assigned to them.
There are several different types of ISDN service. You must know what type you have. In
addition, ISDN circuits in the US and some other countries may also have Service
Profile IDentification (SPID) numbers. SPIDs, when used, must be programmed into the
Zephyr. In rare circumstances, US users may also need Directory Numbers (DNs) if the
telephone numbers are not incorporated into the SPIDs.
Here is a summary of what you need to know and a place to write it down. You may
want to make a copy of this page and keep it next to your Zephyr.

ISDN TIP!
If you have European ISDN or AT&T Point-to-Point, it is
acceptable if you only have one number that applies to both
lines. If you have another ISDN type and only one number,
contact Telos Customer Support.
