Buffers & Channels 14-2 Revision D
(§14.8). Outputs from the buffers are routed to the output
channels using the
XFER, CNTL XFER and ALT XFER
functions (§14.9 and §14.10).
NOTE
The MAX!> must be equipped with
the optional second buffer in order for
CHNG and CNTL CHNG to be
operational.
The system default on the iNFiNiT! and MAX!> assigns
Buffer 1 to CHANNEL A AIR and Buffer 2 to PRE-
VIEW whenever entering Message Compose. CHAN-
NEL B is unassigned. The default active buffer and
channel is
1 A AIR.
The following table defines terms used in frame buffer
and channel operations.

Frame buffer
or buffer
Buffers, also called frame buffers, can be likened to trans-
parent pages. You do your work on one “page” at a time
(i.e. the active buffer). By using the
CHNG or CNTL
CHNG
functions, you can change which “page” or buffer
that you are working on. The “pages” can be “overlaid” or
mixed in output, so that one appears on top of the other.
The buffers installed as hardware are designated FB-A,
FB-B (if present), and FB-C (if present). In Message Com-
pose, they are referred to as buffers 1, 2, and 3.
You can work in only one buffer at a time.
