.TH pattest 8 "2008-01-08"
.SH NAME
pattest \(em Tests a Pattern for a DAHDI Clear Channel Test
.SH SYNOPSIS
.B pattest
.I dahdi-device
.SH DESCRIPTION
.B pattest
Receives test data from a DAHDI channel and checks if it matches the
test pattern. The channel should be of CLEAR signalling (e.g: B channel
of a PRI line). patgen(8) is used to generate the data at the other side.
.B pattest
Must be able to read from the channel. Hence this cannot be used for a
channel used by Asterisk.
The pattern is a simple series of values from 0 to 255. Hence it takes
at most one sample to get in sync with the other side. If there is no
output, all is well. Output is an error message.
.SH OPTIONS
.I dahdi-device
.RS
A DAHDI device file.
.RE
.SH EXAMPLE
pattest /dev/dahdi/5
.SH BUGS
Will not work with channels whose number > 249 as they don't have device
files. For a simple workaround, see dahdi_diag.c .
Gives way too many errors when does not get any input.
.SH SEE ALSO
patgen(8), dahdi_cfg(8), asterisk(8).
