At the end of 1999, Deutsche Telekom AG launched a new product (T-ISDN DSL, also known

as T-DSL) which combines fast Internet access with enhanced T-ISDN telephony features.

(Other providers, for example, in the Netherlands, use DSL with the PPTP protocol).

T-ISDN DSL is first and foremost a normal T-Net or ISDN connection as a multi-device or sys-

tem connection.

Over and above the functions of the normal T-Net or ISDN connection, the T-DSL connection

has a data interface for Internet connections with a speed of 768 Kbps downstream and 128

Kbps upstream. The use of this data interface does not seize any T-Net or ISDN channels.

In contrast to T-ISDN, the NTBA is not connected directly to the main station but rather down-

stream of a splitter (BBAE). This device can be seen as a DSL-speed distributor between the

ISDN connection and data transmission.

The splitter has a TAE jack to which the NTBA is connected. The connection to the HiPath 3000

is set up in the conventional manner.

In addition, the splitter features a connection for the T-DSL modem (NTBBA) which provides

the interface for data transmission at T-DSL speed.
