Telos Zephyr Xstream - Manual (Page 335)

Appendix 6 – Special Operational Modes 323
V.35 SINGLE Mode (high speed V.35/X.21 synchronous operation)
The menus and operation of the Xstream when using the V.35 Split setting of the Interface
selection in the third TEL menu are identical to those for ISDN option for that parameter. This is
documented in the main body of this manual.
When V.35 Single mode is set for Interface selection in the third TEL menu, certain menus
change. We will document those settings here.
The V.35 Single mode is appropriate for situations where a single synchronous network
connection at 96, 112, 128, 256, or 368kbps is available via a V.35 or X.21 interface.

HOT TIP!
Layer 3 offers operation at 112, 128, and 256 kbps only. This is because at 384 kbps Layer 2
or AAC is preferred over Layer 3.
96 kbps operation is offered only in AAC.

Transmit:
The Transmit setting determines what standard (i.e. Algorithm) is used to encode the audio to
be sent to the far end. Identical audio streams will be output from both V.35/X.21 port. Each
mode offers distinct advantages and disadvantages (see section 6.2 for additional information),
as follows:
L3 Stereo and L3 J‐Stereo
L3 Stereo is appropriate for situations where the audio transmitted will be
subject to playback over Surround Sound systems (i.e. mostly for Television). In
most other scenarios J‐Stereo is preferred.
Offers 15 kHz audio frequency response if the Sample Rate is set to 32, or 20
kHz audio frequency response if the Sample Rate is set to 48 kHz.
