G.3 Communication Buffer Channel
A communication buffer channel is used for giving and receiving data between the MSG-SND/ MSG-RCV function
and communication device. This data buffer is composed of single or multiple channels, and each channel is distin-
guished by a communication buffer channel number.
The communication buffer channel is associated with a connection by setting the input item Ch-No (communication
buffer channel number) of the MSG-SND/ MSG-RCV function and PARAM02 (connection number) in Param (param-
eter list).
A connection is configuration information for communication between local and remote stations, and is set in the
218IF or 218IFA Parameter Setting Window of the MPE720 module configuration definition.

A schematic diagram of the communication buffer channel is shown in the next page.
