asterisk users - Apr 2003 - torisa rev b

?Hola!

torisa.c (from zaptel 0.50) says:

#define MASTERVAL 0x41          /* Enable E1 master clock on Rev. B board */

Does that mean that there is a torisa revB? If so, are the schematics
downloadable from somewhere? (www.zapatatelephony.org only has Rev. A
ones)

Does the Rev. A support E1? (just changing the DS2151 for DS2153, the DS
crystal and closing the E1 jumpers, or something else is needed?)

Thanks,

Rev A works OK as a slave E1, but it cannot be a clock master. Rev B was 
a minor update to fix that. The changes are quite minor. I don't know if 
it got past the planning stage to actual artwork, though. As a T1 card 
Rev A works OK as both a clock master and a clock slave. The changes you 
describe will make Rev A work OK as a pair of clock slave E1 ports.
