Pressing the TEL a third time will show this menu. The options for this menu are as follows:
Telco
This is the protocol for your ISDN circuit. Outside of the USA & Canada, it is usually ETS 300
(Euro ISDN). In the USA & Canada, the most common protocol is National ISDN 1 (use the Natl.I‐
1 setting). In Japan it will be INS 65 (Japanese ISDN).

IMPORTANT!
Each ISDN circuit has a certain ISDN protocol (or "switch type") that the phone company
should have given you. By far the most common protocols in the USA & Canada are National
ISDN-1 & National ISDN-2 in which case you should set the Telco setting to Natl.I-1.
If you do not know what protocol your line is configured for, try Natl.I-1 first. If that does not
work, see Section 11 (Detailed Menu Reference) for hints on how to guess your protocol.
In Section 11 (Detailed Menu Reference), we've included numerous tips in how to guess your
Telco setting for users in the USA & Canada.

ZEPHYR CLASSIC VS XSTREAM COMPARISON!
The Zephyr classic does not distinguish between "National ISDN-1" protocol and "DMS-100
Custom Functional" protocol - Both use the Natl I-1 setting. This is not true for the Xstream. If
unsure which is correct for your ISDN circuit, try both settings.
Auto Ans.
This determines whether your Xstream will automatically connect to incoming calls. When set
to All it will answer incoming calls. You will hear a "bleep" sound when this happens.
When set to None the unit will make a "ringing" sound when there is an incoming call. A
message is displayed on the LCD screen showing the calling party number (if available) and
options allowing you to accept or reject the call.
You can also select Zephyr or Phone, which will cause the unit to only accept data or voice
telephone calls, respectively. Other types of calls would require manual treatment, as detailed
above.
