pattest — Tests a Pattern for a DAHDI Clear Channel Test
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.
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.
A DAHDI device. Can be either a device number or an explicit device file name
Gives way too many errors when does not get any input.
patgen(8), dahdi_cfg(8), asterisk(8).
