I learn something every day.

Mexico and some other countries in latin america actually uses a weird combination of T1 and EuroISDN I am told.

I see in libpri that PRI_SWITCH_EUROISDN_T1 is coded differently from 
PRI_SWITCH_EUROISDN_E1. What exactly is the T1 version of EuroISDN and 
where do I find this standard?


   

        
ETSI. Where else would you expect to find a EuroISDN spec?

There are no special EuroISDN for T1 in ETSI that would be different 
from an E1. I don't even think ETSI has a T1 spec?
    

It can be hard to find specifications in the ETSI system, because their 
document naming and search facilities are somewhat lacking. I never 
understood why it was specified, or who might use it. However, there are 
specific ETSI documents for EuroISDN over T1. I've stumbled on them in 
the past and been puzzled. As far as I recall, they say little that is 
surprising. Its just the same as over E1, but the last channel in 
channel D, and the maximum B channel are only 0 to 22.

Regards,
Steve
