Hello group,

I came across this great web site http://kropla.com/ which has good
information for world travellers. It has details of telephone jacks, power
socket types, etc for various countries around the world. 

I was wondering if there was a website similar to this which has details of
Telecom issues for various countries. Issues like, Analog/ISDN signalling
protocols, (eg : different Cadence types, line reversal or wait states etc,
and overlap receive or enbloc receive, etc ) , Caller ID signalling
(ETSI-FSK, DTMF, etc).

Our product is a PABX with analog , ISDN BRA and PRA trunks.
