troubleshoot. Therefore, we expect that most repairs will need to be done by Telos or our
authorized representatives. See page III for details on obtaining service or support.
However, there are a few sub‐assemblies, which are field replaceable. You can purchase the
following spare parts, if desired.
ISDN S + U Interface Telos Part # 1701‐00023 (old # 9456‐0000) for 10 Base‐T hardware only
ISDN S + U Interface Telos Part # 1701‐00153 (for 100 Base‐T and 10 Base‐T hardware. Requires
software version 3.x or later)
V.35/X.21 Interface Option Card Telos Part # 1701‐00006 (old # 9454‐0000)
Zephyr Xstream Power Supply Telos Part # 1281‐0006
Zephyr Xstream SIMM memory module (10 Base‐T hardware version only) Telos Part # 1166‐
0005‐XS‐version (specify "Zephyr Xstream" and the desired version on your order)
NOTE: When installing the 1701‐00023 ISDN S + U Interface be sure the following jumpers are
correctly set:
JP2 must short pins 1 and 2 (down position)
JP1 and JP3 should be set as indicated above.
13.2 Updating Firmware
The procedure for updating units is one area where early units (with 10 Base‐T Ethernet port)
and newer Xstreams (with 100 Base‐T Ethernet and Livewire) differ substantially. The early unit
request updates from the FTP server specified in the System menu (this might be a local
machine running a special updater/FTP server, or it might be a remote FTP server such as the
one at Telos.
The newer units (with 100 Base‐T) are updated via the web browser. In this case, the
appropriate files are downloaded from Telos to the local machine. Then, from the web browser,
the user specifies the path to the files when the update process is initiated.
Please consult the appropriate section for your unit.
NOTE: You can determine if your unit has the newer 100 Base‐T hardware by checking your
software version in the first SYSTEM screen. If your software version ends in "I" or "P" you have
older 10 Base‐T hardware. If your version ends in "B" or "R" you have the 100 Base‐T hardware.
13.3 Updating Xstreams with the 100 Base-T hardware
The Xstream has two internal memory “banks”. Each bank contains room for a complete
version of operating software. This approach allows a software update download to be
completed and checked without danger of making the unit inoperable if the download were to
be incomplete or corrupted. It also provides and easy way to try a new software version and
still return to the old version.
The software version in each bank is displayed on the System Parameters page as shown below.
To change banks simply click in the “radio button” for the desired bank and then click on Apply.
