Telos Zephyr Xstream User Manual page 172

The compact plug at one end of the cable snaps onto the mating connector on the Zephyr
Xstream with a locking action. To release the plug, the two pushbuttons at either end of the
plug housing are pressed simultaneously and the plug is withdrawn.

IMPORTANT!
We had to use a small socket in order to make more room on the rear panel (sorry), so you
cannot plug directly into it with off-the-shelf cables. You must have the appropriate cable
from Telos to connect!
The Xstream uses the same cables as the Zephyr.
The V.35/X.21 interface, while a single physical plug, has two electrical ports, of which one or
both may be used.
The plugs at the other end are labeled "PORT 1" and "PORT 2" and are connected to
the TA/CSU as follows:
One Port Operation
•
For one‐port mono operation, only the PORT 1 plug is used. It connects to
the TA/CSU V.35/X.21 socket.
•
In the mono 64 modes, only one V.35/X.21 connection is required. Audio
channel A corresponds to PORT 1 and audio channel B corresponds to PORT
2 (usually not used in this case).
Single port operation supporting 56 or 64 kbps for mono operation on a single V.35/X.21 port.
Interface in the TEL menu should be set to" V.35 Split"
•
For high bit‐rate applications using one port
