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 has a list of modems that have been tested with our DSLAMs (See below). 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.
To ensure that your Internet access is secured from intrusions the following steps are advisable.
Instructions regarding the above security measures are published in the user guides for the Telkom supplied modems.
Further measures to protect your service from intrusions includes
Security is a personal decision, Telkom's modems have the functionality to provide a safe wireless environment but is reliant on you the user to activate the built in security measures to limit the risk of intrusion.
Telkom will provide a one-stop service with regard to installation. Once your order is received and validated as feasible, Telkom will activate the network.
If you choose to buy a modem from Telkom, Telkom will also install a surge protector and if required, may help with the installation of required DSL software on your PC, at your premises.
All Telkom branded modems have a full one-year carry-in guarantee. If the modem is faulty while under guarantee the modem must be returned to the nearest Telkom Customer Service Branch to be swapped with a working unit of the same model. The guarantee is non extendable, meaning the replacement modem will only be covered by the balance of the initial one year guarantee.
NOTE: You will need one micro filter for every telephone socket connected to the DSL line on your premises, even if there is no equipment connected to that specific socket.
If you purchase a Telkom modem you will receive 2 micro filters in the box, and only need to buy additional micro filters if you have more than 2 telephone sockets on your premises.
Please note: It is important to note that the provision of Telkom's DSL access service is subject to network availability, distance, copper quality and line sync speed limitations. Telkom would therefore advise you not to purchase a DSL modem prior to confirmation that service can be provided.
