1 Overview
The YLB04 is a general-purpose overseas T-Box (telematics box) with an integrated in-vehicle emergency call
terminal, planned by Foton Zhike and independently developed by Yaxon (Yaxun). It complies with the regulatory
requirements of the EU, the Middle East and other regions. The NG-eCall function of this product is mainly used, in
emergency situations, to establish a hands-free call with the emergency call system service platform manually or
automatically and to transmit vehicle information, including vehicle characteristics, vehicle position, time, etc. This
product is applicable to M1 and N1 category vehicles.
In addition, this product can also implement Foton's overseas connected-vehicle functions (data collection,
remote OTA, remote diagnostics). This document focuses on the NG-eCall function and does not describe the T-
Box connected-vehicle functions in detail.
