Operating Manual for FLASHMAN II
In Remote mode, FLASHMAN II uses FlashCast technology, which means:
FLASHMAN II to FLASHMAN II transmission:
the ‘dialling FLASHMAN II’ passes over its parameters to the receiver.
FLASHMAN II / non Mayah Codecs transmission:
FLASHMAN II evaluates the settings of the other side and configures itself
automatically.
In most cases 'Remote' is the best setting. Don't change it unless you
know what you do!
j) Format /IMUX (applicable only for ISDN):
sets the Profile IMUX (Inverse Multiplexer) format at ISDN transmissions to one
of the following:
·
Auto (default, recommended)
·
CDQ/H.221
· Musictaxi
· J.52
· Micda
· APTX
Inverse Multiplexing is necessary for the correct synchronisation of multiple B-
channels in an ISDN transmission. If the IMUX format is set to Auto, the
FLASHMAN II will automatically recognise the correct format in most cases.
The most often required exception are the connections to the older
APT-X codecs over ISDN. Here the IMUX format must be set to
APTX.
k) Ancillary mode:
determines how to Encode/Decode the Ancillary (auxiliary) data carried in the
audio data stream. FLASHMAN II uses ancillary data transport for both GPIO
signals transport and
·
Auto (default, except of APT-X algorithms)
·
CCS
·
J.52
·
Musictaxi
·
Barco
·
None (only with APT-X algorithms, default)
·
Left (only with APT-X algorithms)
·
Right (only with APT-X algorithms)
l) Protection (applicable only for MPEG algorithms)
at some algorithms such as MPEG-1 Layer 2 it is possible to enter CRC
Protection Bit value here. It works with different parameters for MPEG
algorithms. (CRC= Cycle Redundancy Check)
