Page 10: Interface And Channel Number Identification
Figure 2-7 NT200 2.2 Interface and Channel Number Identification The BRI16 full-length board uses the RJ45 interface. The motherboard and the daughterboard respectively provide four 8-pin RJ45 jacks each of which corresponds to one module and two BRI channels. That is to say each RJ45 jack has 8 pins and corresponds to two S/T interfaces. See below for the pin layout of the RJ45 jack with two different modules. - Page 11 Pin8 correspond to the other. In this way, each RJ45 accommodates two channels. A BRI16 full-length board provide up to 16 channels each of which has a fixed number. Figure 2-8 below illustrates the corresponding relations among the RJ45 interfaces on the motherboard, the channels and the modules.
