Terminal Equipment Type 1 (TE1): understands how to interface to the ISDN network
- Can connect directly to the ISDN
- E.g.: ISDN interface card or USB device

|
Terminal Equipment Type 2 (TE2): understands nothing about ISDN
- Must use a Terminal Adapter (TA) in order to be connected to ISDN.
- Examples: modem, fax, analogue telephone, PC Serial Port. (Perhaps even
a television camera).
A Terminal Adapter is required to connect a TE2 device to the
ISDN network.
A Terminal Adapter is by definition the equipment needed to connect a TE2
to an ISDN. |
