TECHNICIAN COMMANDS
The following options are to be used by trained field technicians to set up the Phonecell
®
SX5D
for operation in the network. To prevent casual access to these options, which can directly affect
the proper operation of the unit, these options are protected by a Service PIN.
To Access the Service menu, press the MENU key, select Settings, then select Service Settings.
You will be prompted to enter the Service PIN before you can access any Service menu items.
Each option is described below, along with the available settings and the system defaults
Service Settings
Mobile Equipment Personalization (MEP) Locks: The five locks available are SIM, Network,
Network Subset, Provider, and Corporate. With the correct password, you can activate,
deactivate, disable, or check the status of any MEP lock. Once a lock is disabled, it cannot be
reactivated.
Dial Tone Type: This dial tone will be the air interface (GSM) dial tone presented to the user on
the desk phone and any POTS phones connected to the SX5D. The available options are 425
Hz and Dual Frequency (default).
Audio In: Changes the input impedance. Options are 600 Ohms (default) or 900 Ohms.
Supervision Pulse: Changes the pulse that is generated when the far end answers a call origi-
nated from the SX5D. Options are 12 kHz (default), 16 kHz., Off, Pulse Duration, and Pulse
Level.
Pulse Duration options include any value between 10 and 65535 milliseconds.
Pulse Level options listed by dB ranges (default is -3dB).
Line Reversal: Enables line reversal on tip and ring for incoming calls.
Line Reversal (MO) can be turned On or Off (default).
Line Reversal (MT) can be turned On or Off (default).
Line Ringing: Controls the line ringer.
Frequency options are 20 Hz (default), 25 Hz, or 50Hz.
Cadence options range from.1 to 25.5 seconds (by 100 millisecond increments).
Disconnect Pulse: Sets pulse value. Options range from 10 to 65535 milliseconds.
Dial Tone After Disconnect: Determines if a dial tone is heard after far end disconnect. If On,
then dial tone will start at some time after a far end disconnect is detected as long as the user is
still off hook (The default setting is Off).
Receiver Off Hook (ROH) Setup: Sets the parameters of the ROH tone that is heard when the
SX5 goes off hook for an extended period of time without making a call. Options are Continuous
or Non-continuous, Set Start Time, and Set Stop Time.
Self Test Interval: Sets the reset interval for periodic resetting or sanity checking. The range is 0
to 65536 minutes, where 0 means that there is no resetting.
SERVICE PIN: Options are On (default) or Off, and Change PIN. If the Service PIN is entered
wrong three consecutive times, you will be returned to the Main Menu.
RF: Displays the quality and signal level of the received signal (for evaluation of SX5D place-
ment, etc). The display will show a dB level for received signal strength and/or a decimal value
representing the signal quality (BER, FER, etc.). The signal strength will be on row 2 and the sig-
nal quality value will be on row 3.
Restore Service DEFAULTS: Resets all service items to factory defaults separately from the
user settings.
