IMPORTANT TIP!

It is important to understand that the Transmit and Receive settings on two connected units

may very well NOT match. This is because there are frequently times when it is appropriate

to use a different coding mode coming versus going.

The important thing to remember is that the local Transmit mode must be compatible with the

Receive settings and capabilities of the far end unit.

Whereas the local Receive mode must be compatible with the Transmit settings of the far

end unit.

COMPATIBILITY TIP!

Some brands of codecs have proprietary protocols implemented. These codecs require that

they be placed in "Independent mode" or bi-directional communication with standard

ISO/MPEG codecs is not possible.

COMPATIBILITY TIP!

The Zephyr Xstream specifies the bit rate per ISDN or V.35/X.21 channel. Since certain

modes (i.e. stereo or mono-128) require two channels to operate, the total (aggregate) bit

rate would be double the number displayed in these cases.

This is important as some other brands of codecs specify the total bit rate.
