The relevant portions are Recommendation E.180 to E.183, and in particular supplement no. 2 which contains specific national information for all countries outside North America. Supplement no. 3 refers to North America. I can't make any claims about the accuracy or up-to-date nature of this information. The relevant national Standards apply and surely take precedent where they differ from CCITT.
