CH - 显示频道编号，GSM900的范围是1~124，GSM1800的范围是512~885 如果该系统商有开启跳频(Freq。Hopping)，通话中频道编号前会用"H" 以资识别，并显示跳频所使用的频道编号。
RxL - 显示接收强度(单位:-dBm)，范围从-110~0
TxPwr - 显示通话中手机的功率发射强度(Power Level)，显示范围0~19。 TS - 时槽(Time Slot)，TS=0~7，其中TS 0为BCCH所使用。
TA - Time Advance，时间前置量，显示手机和基站间距离。该数值乘以500可 换算为公尺，不过因受电波反射吸收等影响，TA值仅供参考用。TA值范围0~63 RLT - Radio Link Timeout。 如果是负的值，则显示0。最大值为64。 当手机没有通话时，则会显示xx
RQ - 通话品质，0~7，数值越大，通话品质越差。
C1 - 路径损失参数(Path Loss Criterion)，供手机决定频道选定的参数。 C1=〔A-Max(B，0)〕 dBm
A=RxAv(平均接收强度)-RxLev_Access_Min(最低入网强度)

C2 - 细胞重新选择参数(Cell Reselection Criterion)。
C2用以决定重新选择细胞的时机。
CHT - Channel Type，显示现在使用中频道类型，共有以下数种
* AGCH -(Access Grant Channel)允许连结频道
由网络到手机的单向频道，安排专用控制频道以完成连结上网
* SDCC -(SDCCH:Stand-alone Dedicated Control Channel)独立专用控制频道 * TXX -(TCH:Traffic Channels)业务频道
xx为通话中语音编码速率。有HR，FR，EFR等
HR=半速率编码
FR=全速率编码
EFR=加强型全速率编码
* BCCH -(Broadcast Control Channel)广播控制用频道
* CBCH -(Cell Broadcast Channel)细胞广播频道
* SEAR -(Searching)手机正在搜寻网络讯号
* NSPS -(No Service & Power Save)，无系统服务，手机处于省电模式
通话中CHT项变化:AGCH->SDCC->TFR(TEFR)->挂断电话->BCCH->CCCH 开机时CHT项变化:AGCH->SDCC->BCCH->CCCH

AGCH - Access Grant Channel - is the answer to RACH. It's used to assign a mobile a Stand-alone Dedicated Control Channel (SDCCH). It's downlink and point to point channel. SDCC - (SDCCH) Stand-alone Dedicated Control Channel - It's used for system sygnalling: cell set-up, authentication, location update, assigment to traffic channels and transmission of short messages
TFR - (TCH) Traffic Channels - Physical channels also transfer user data, which can be either in the form of Half Rate traffic (6.5kbit/s) or Full Rate (13kbit/s). Another form of traffic channel is the Enhanced Full Rate (EFR) Traffich Channel. The speech coding in EFR is still dona at 13kbit/s, but the coding mechanism is different than that used for normal full rate traffic. EFR coding gives better speech quality than normal full rate. Traffic channels can transmit both speech and data. these are bi-directional channels.
BCCH - Broadcast Control Channel contains detailed network and cell specific information such as:
Frequencies used in the particular cell.
Frequency hopping sequence.
Channel Combination. In the GSM there are eleven logical channels. Depending on the number of frequencies used in a cell, the number of physical channels available is eight times the number of used frequecies. most of these physical channels have to be allocated for traffic purposes. There are more than one ways in these aleven logical channels are mapped on the available physical channels. How they are mapped varies from cell to cell depending on a number of categories. Channel combination tells about the mapping method used in the particular cell
Paging groups. Normally in one cell there are more than one paging channels. To prevent a mobile to listening to all the paging channels for a paging message, the paging channels are divided such that, a group of mobile stations listen to a particular paging channel only.
Information on surrounding cells. A mobile station has to know what are the cells surrounding the present cell and what frequencies are being broadcast on them. This is necessary if, for example, the user initiates a conversation in the current cell, and then decides to move on. The MS has measure the signal strength and quality of the surrounding cells and report to the base station controller.
SEARCH Mobile Station is searching for signal.

This test is meant to be used when some cells are tested prior taking them into commercial use. By setting the barring on in the base station normal GSM phones will not try to register these barred cells. By selecting cell barring reversed, the MS will only use the cells to be tested. However, if at the same time it is wanted that MS will be capable to use normal network cell barring ignored can be set.
This test can be activated only from the MENU selecting item field test, or with shortcut menu-10-19. When MENU is not active and the user is scrolling field test display with NEXT and PREVIOUS, display 19 won't be activated.
