The MJ-1 module jig has one PWB; the Test-PWB.
The Test-PWB connects
• all test points (including the power supply Connection)

• the RS232 testpattern.
Additionally there are some connectors and a SIM holder mounted on the Test-PWB. The
flashing and the M/FBUS control is enabled via standard modular connectors. The Test-
PWB is shown in Figure 2.
