style jack, just like on a standard telephone. If the problem continues, you should "reseat" the
ISDN card. This state could indicate a marginal ISDN line. If the problem persists, contact Telos
Customer Support. *
NOTES:
** If you reboot the unit and the LED stays either off or on, even with no ISDN attached, there is
a problem. If the Zephyr otherwise seems to be operational (i.e. the keyboard and LCD screen
and meters are functioning) it indicates a bad Terminal Adaptor Card (95%). You should
"reseat" the ISDN card. If the problem persists, contact Telos Customer Support.
* If the phone company tests the line and claims it is ok, ask them what brand and model of
"switch" you are on. Also, ask them if you are on "straight copper" or if you are on any kind of
"repeater" or "loop extender". Ask them how far you are from the switch or nearest repeater.
Call Telos Customer Support and give them this information.
External NT1's have one or more indicators, which can help differentiate line vs. Zephyr Xstream
problems. See your NT1 manual for details.
The TEL Status Screen
The status of each B channel is shown here. Press the TEL button once to view this screen. The
same status information is displayed on the default timeout screen.
The system tries to initialize the ISDN circuit upon boot up. ISDN circuits requiring SPIDS
(generally needed in the USA & Canada, never needed outside these countries) will display SPID
Error if the SPID for specific channel is incorrect.
Note that you may get a false Ready indication if the TELCO setting (in the second TEL menu) is
set incorrectly or if no SPIDs are entered when they are required. For status of the NT1 observe
the state of the Green LED next to the U interface.
Available line status messages are:
Inactive
SPID Pending
SPID Error
Ready
Pending Seize

USER'S MANUAL
No line connected, or connected to wrong jack on the
Xstream. Or, ETS 300 permits the Telco to put a line to
sleep. Inactivate will be displayed when this occurs.
S interface is initialized and the SPID has been sent to the
Telco switch and Xstream is waiting for it to be accepted.
May also be seen intermittently before the S interface has
initialized
The SPID sent to network has not been accepted by the
switch (DMS Cust. and Natl I‐1 only).
The unit sees a live ISDN S interface (i.e. external NT1 is
present or internal NT1 has completed startup) and initial
ISDN protocol initialization is complete.
Outgoing call in process; Request for call has been sent to
Telco switch.
