A Terminal Adapter does not necessarily need to have a CODEC inside it.
For example, a basic Terminal Adapter could connect a PC via its serial port to an ISDN network without any requirement for a CODEC.
The bit stream from the serial port is digital, as is the bit stream that goes out to the ISDN. Although a protocol conversion does indeed occur, it is not an analogue to digital conversion, so no CODEC is required.
On the other hand, when an analogue device, such as a fax machine, needs to be connected, then an analogue to digital conversion is necessary and a CODEC will be required.
So, simple Terminal Adapters do not need to have CODECs, but they cannot connect analogue devices to the ISDN.
More sophisticated Terminal Adapters that are able to connect analogue devices to the ISDN do need to have a CODEC.
