Section 3 ZEPHYR AT A GLANCE

•
Connect to an external NT1.
•
Allow connection to another ISDN device, such as another Zephyr or an ISDN
telephone.
•
If using the PS- 2 power available on the S interface, the jumper JP- 1 on the ISDN
terminal adapter card must be between Pins 1 and 2.
Europe and other
The ISDN interface has only an S/T connection. It must be used with an external NT1, a
device usually provided by the telephone authority.
More information can be found in the Installation/Operation and ISDN sections.
This version, identified with the Euro telecom approval mark (looks like 2 hockey sticks
in a circle), does not provide power on the S/T interface.
IMPORTANT!
An RJ-11 style 6-position plug can be plugged into the center
of an RJ-45 style 8-position jack if your Telco charged you
extra and installed an RJ-45 jack for your ISDN line.
IMPORTANT!
If using an external NT1, or connecting another device, be
sure to check power arrangements. The Zephyr provides “PS-
2” power on the S/T jack. If your NT1 or other device has an
external power supply it is essential that the 2 power leads not
be interconnected or damage to the Zephyr, external
equipment, or both, may occur. Contact Telos Systems
customer support for additional information, if needed.
IMPORTANT!
In this case, the NT1 will be powered by the Telco. If your
Zephyr’s terminal adapter does not show the Euro telecom
approval symbol (looks like 2 hockey sticks in a circle) you
should contact Telos Systems customer support before
proceeding. This is because the Zephyr’s built in supply and
the power supply from the NT1 can conflict and cause damage
to the Zephyr, NT1, or both.
