pure socket telecom.

[Andrey Yasharov]

Пожалуйста, помогите перевести.
pure socket
Выражение встречается в следующем контексте:

The xDR-generation has three main interfaces towards third party systems; pure socket (real-time), file server (near real-time), and database (near real-time).
Pure socket
xDRs are sent in a binary stream according to the specified xDR format.
The third party system must be able to read data from the socket at the same speed as OSIX sends data. If the third party system is too slow, or disconnects, a backup functionality is activated.
