[Asterisk-Users] PRI protocol question...

The legend looks OK, When the PRI is idle, it too looks OK. When a call is 
routed from asterisk to the LEGEND, * can no longer find the d-channel and 
the pri is reset. This problem seems to be due to the limited pri 
implementation available on the Legend, thus the protocol question. 
Additionally, there is a legend forum and one of the doc sheets mentioned 
that pri providers have reported not being able to see the dchannel with 
various pieces of equipment.

>>I'm having difficulty getting a PRI working between asterisk and a Merlin
Legend. I have been attempting to get it going as esf, b8zs & 5ess (although
I have tried other switchtypes...).  I found the following info in the
Legend
docs:

If the switch type is 5ESS, the protocol MUST be set for ATT Custom.
If switch type is DMS-100, the protocol MUST be set for NTNAPRI

The README in libpri implies that switchtype=5ess is ATT Custom

from README:
...it has been tested work with NI-2, Nortel DMS-100, and Lucent 5E Custom
protocols on switches from Nortel and Lucent.
  
Is the protocol set to ATT Custom with the switchtype=5ess parameter? Are
the terms ATT Custom or NTNAPRI meaningfull to asterisk?

Thanks,

John
