(Differences to the phone-type TP 9070 DTFX are very small)

Indication of the firmware-version:

Preparing for diagnostic-menu (= monitor-mode)

as following for these phones:
cellular flip-phone (GSM-900): Teleport TP 9040, TP 9050,
TP 9070 DTFX, TP 9080 / 9082
(GSM-1800): TP 1850, E-Plus AEG-compact, TP 1870 DTFX
TP 1880 /1882
and models looking identically than these (e.g. NorTel,
Matra or Sanyo, consider the referring pictures at the side !):

Diagnostic-function turning off:

IDLE - Display (three lines):

Idle mode

Broadcast control channel serving cell
(xxx from 001 to 124) (in example 19).

National color code
(in Germany 3 for D1 or 7 for D2) (in example 3).

Base station color code
(in Germany x from 0 to 7) (in example 1).

absolut Receive level
from 0 (= - 110 dBm) to 87 (= - 23 dBm) (xx in example 42 = - 68 dBm).

Link count
a kind of RadioLinkTimeout counter,
start counter is preset in the parameters of the base station;
if one block can not be decoded, one will be subtracted;
if the next block can be decoded, two will be added up to a maximum
level defined by the base station.
If the counter is zero, the connection will be interrupted
(in idle-mode with active SIM in the home-net 15).
(One block are four frames).

Signal to Noise Ratio in dB
(with good receive-level in home-net 15).

AFC (Automatic Frequency Control) value
digital control value for the frequency
(only 9070 DTFX since firmware-version 7207-1/DTFX).
The digital AFC-value shown on the display and the real
frequency-correction in Hz are attached through a nonlinear
signature-line. An example:
An increase about 1 in AFC-value means a difference
about 20 - 40 Hz (900 MHz), on DCS (1800 MHZ) it's twice the value.

Neighbour channels
scanning up to six neighbour channels
(example s.a.).

DEDICATED - Display (three lines):

Dedicated mode

Absolute radio frequency channel number =
channel where your call works (xxx from 001 to 124) (in example channel 19).
(combination of TCH + SACCH or SDCCH + SACCH)
If there is an "H" displayed, frequency-hopping is used.

Time slot = time slot in which the phone is sending (x from 0 to 7) (in example 5).

absolut Receive level
from 0 (= - 110 dBm) to 87 (= - 23 dBm) (xx in example 41 = -69 dBm).

Bit Error Rate (in example 0 = 0.2 %)

Q	0	1	2	3	4	5	6	7
BER	0.2 %	0.4 %	0.8 %	1.6 %	3.2 %	6.4 %	12.8 %	25.6 %

Link count
a kind of RadioLinkTimeout counter,
start counter is preset in the parameters of the base station;
if one block can not be decoded, one will be subtracted;
if the next block can be decoded, two will be added up to a maximum
level defined by the base station.
If the counter is zero, the connection will be interrupted
(in dedicated-mode with active SIM in the home-net 24).
(One block are four frames).

Timing Advance
Dividing through 2 is distance to the BTS in km.
Or multiplicate the value with 547 m (a little bit more exact).

actual TxPwr
actual TxPower in dedicated mode, e.g.:

( X 0	43 dBm	20 W )
( X 1	41 dBm	12 W )
( X 2	39 dBm	8 W )
( X 3	37 dBm	5 W )
( X 4	35 dBm	3.16 W )
X 5	33 dBm	2 W
X 6	31 dBm	1.26 W
X 7	29 dBm	794 mW
X 8	27 dBm	501 mW
X 9	25 dBm	316 mW
X 10	23 dBm	199 mW
X 11	21 dBm	125 mW
X 12	19 dBm	79 mW
X 13	17 dBm	50 mW
X 14	15 dBm	32 mW
X 15	13 dBm	20 mW

Signal to Noise Ratio in dB
a kind of S/N-counter
(with good receive-level in home-net 15).

Neighbour channels (BCCHs, see Idle-mode)
scanning up to six neighbour channels
(example s.a.).

as seventh display at "N" the first row from Idle mode (without RxLev):
BCCH : NCC & BCC (= BCCH of the Server Cell).

Other Displays (three lines):

Access
shows the access of the MS or BTS to the organization channels.
Accesses to the RACH and PCH.

Power Measurement

Synchronization

The menupoint "diagnostic":

ON or OFF (default: OFF)

a time period between 1 and 9 (default: 5).
With this you can change the switching period between standard- and
diagnostic-screen.
A number under three turns permanently on the diagnostic-screen.

choosing this clears the Errlog-memory.

choosing the Errlog-level.
These points (-3 and -4) have no effect for the user.

ON or OFF (Auto Interogate, default: ON)
Without function, works only with external PC-Program.

is identical with IDLE- and DEDICATED-screen

shows information of the phone

shows the serial number of the phone (IMEI)
