Compatibility of modems

The equipment at the exchange end of your DSL line is known as a DSLAM (Digital Subscriber Line Access Multiplexer).

DSLAMs comply with international standards. The principal reference is ITU-T (International Telecommunication Union - Telecommunications Sector) Recommendation G.992.1. The modem you use on your end of the line must comply with the same standard.

Telkom publishes a List of Modems that have been tested with our DSLAMs . Manufacturers and distributors may submit their modems for testing. ICASA (Independent Communications Authority of SA) published a regulation that governs the regulatory requirements of DSL modems, i.e. Gazette No. 23766, Notice No 1488. To supplement the regulation, Telkom will publish a detailed DSL Network Subscriber Interface Desciptions shortly.The DSLAMs of both Telkom and the Second Network Operator (SNO), and all DSL modems used in South Africa must comply with those specifications.
