Engineering Mode Parameters -- %EM: Introduction This document contains the functional interface description for the engineering mode driver. The purpose of Engineering Mode (EM) is to provide means to observe the behavior of the mobile station and the settings of the network as counterpart and therefore defines a lot of possibilities to analyze the network. The EM can be used for observation of a defined data set during functional test and field test. To get the data it is necessary to insert “AT-Commands”. This can be done via a terminal program such as HyperTerminal or ProComm. The commands are as follows:

• AT%EM=2,1 Serving Cell Information • AT%EM=2,2 Serving Cell GPRS Information • AT%EM=2,3 Neighbour Cell Information • AT%EM=2,4 Location and Paging Parameters • AT%EM=2,5 PLMN Parameters • AT%EM=2,6 Ciphering, Hopping, DTX Parameters • AT%EM=2,7 Power Parameters • AT%EM=2,8 Identity Parameters • AT%EM=2,10 GMM Information • AT%EM=2,11 GRLC Information • AT%EM=2,12 AMR Configuration Information • AT%EM=2,13 PDP Information • AT%EM=2,14 Throughput Information

!

The display of certain parameters is dependent on the wireless network sending the correct information in the System Information Packets. There is no guaranty that the information is always forwarded from the network. At times data may not be present to display in the Engineering Mode responses.
