The following commands determine the kind of protocol data to be captured by the EPA: AT Command ATCDn CD0 CD1 ATCBn CB0 CB1 ATCCn CC0 CC1 Description Disable the capture of D-channel protocols Enable the capture of D-channel protocols (default) Disable the capture of B-channel protocols (default) Enable the capture of B-channel protocols Disable the capture of DTE-DCE interface protocols(default) Enable the capture of DTE-DCE interface protocols The EPA starts to capture data when the command ATCT is issued. This capturing process will continue until the command ATC$ is issued. The EPA maintains 8 Kbytes RAM as a ring buffer. In case the buffer is full, the earliest data captured will be overwritten by the latest data. Analyzing the Captured Data To view the analyzed result, use the command ATC$. For your convenience, the relevant AT commands are summarized as follows: Command ATCT Description Clears buffer and starts the embedded protocol analyzer. Captures data immediately and starts the timer. 109

The following commands determine the kind of protocol data to be
captured by the EPA:
AT Command
Description
ATCDn
CD0
Disable the capture of D-channel protocols
CD1
Enable the capture of D-channel protocols
(default)
ATCBn
CB0
Disable the capture of B-channel protocols
(default)
CB1
Enable the capture of B-channel protocols
ATCCn
CC0
Disable the capture of DTE-DCE interface
protocols(default)
CC1
Enable the capture of DTE-DCE interface
protocols
The EPA starts to capture data when the command ATCT is issued.
This capturing process will continue until the command ATC$ is
issued.
The EPA maintains 8 Kbytes RAM as a ring buffer.
In
case the buffer is full, the earliest data captured will be overwritten
by the latest data.
Analyzing the Captured Data
To view the analyzed result, use the command ATC$. For your
convenience, the relevant AT commands are summarized as
follows:
Command
Description
ATCT
Clears buffer and starts the embedded protocol
analyzer. Captures data immediately and starts the
timer.
