What is the difference between ADSL, Uncapped ADSL, ISDN and Diginet or leased line services?
Answer
ADSL
ADSL (Asymmetric Digital Subscriber Line) is an access medium that provides the user with a broadband connection to Telkom's data network. Adsl operates over the same pair of copper wires that is used for telephone service, and is provided only in conjunction with a telephone service. You can make and receive calls or send a fax and surf the Internet at the same time. Telkoms Adsl access service will offer you an always-available connection with no dial-up necessary, no more waiting to establish a connection and no more busy signals. You will not be billed for your connection time when you make use of Telkoms ADSL access services.
The ADSL service is capped at 1, 2, 3, 5, 7, 10 or 20 GB of downloads and uploads per month, depending on service subscribed to.
Telkom, and therefore Eject, does not guarantee any throughput speeds on any ADSL access line.
Uncapped ADSL
The Uncapped ADSL service has no restriction on downloads and uploads, allows for Static TCP/IP addresses so that webserver or email server can be hosted on-site, has no traffic shaping enforced, and needs a specific Router supplied by Eject to operate
ISDN
ISDN (Integrated Services Digital Network) is a switched dial-up connection that enables the user to dial-up to any destination number within the network. A user can therefore access the Internet or a videoconference. Telkom does not guarantee any throughput speeds if a user accesses the Internet utilizing his or her ISDN line. You will be billed for your connection time when you make use of Telkoms ISDN service to surf the Internet.

Diginet / leased line services
Diginet or leased line services is a dedicated point-to-point connection that provides the user with an always on service. You may host Websites or Email servers on a Diginet link, but cannot do so using Adsl. Diginet is based on carrier class Symmetrical Digital Subscriber Line technology that provides guaranteed bandwidths between any predefined destinations. The customer determines the transmission speed throughput of the Diginet services as they chose the appropriate speed with application. There is no traffic congestion due to other users as it is used in a private network topology. This also means that there is no sharing of bandwidth with other customers. As Diginet is a constant bit-rate service it means that there is no slowdown of data transmission speed.
Although Telkom guarantees the Diginet throughput speed it does not guarantee any throughput speeds of the Internet. When a user accesses the Internet utilizing his or her Diginet line the guaranteed throughput stops once the data enters the Internet.
