Shortel IP 230 PABX IP phone.

• LCD 141 columns by 44 rows, but not a straight-forward graphic LCD display. Really more like a character LCD display in that the character positions and size are predetermined and fixed, and there is not a continuously addressable graphics area.

The phone can be powered from 33V to 48V across the bridge rectifier outputs. Tested with Ubiquiti 48V 0.5A +(4,5)pins, -(7,8)pins network power supply, phone plugged into PDE socket.

The are a number of built in test/setup functions obtained by pressing mute (microphone with a line through it) then a series of numbers representing the function names:

• dial 3424# (DIAG)
• dial 4636# (INFO)
• dial 7464# (PING)
• dial 73728# (RESET)
• dial 772667# (RRAMOS), factory reset,
  • at the prompt dial 1234# as password, to enter “KPD Mode”
  • dial 25327# (CLEAR)
• dial 73887# (SETUP)

Keys need to be pressed solidly as sometimes they don't register.

On powerup D2 to D4 light up green then after 2 seconds they go out and D1 flashes red. 10 seconds after powerup D1, D2, D3, D4, D53, D52, D51 flash in sequence. 1 Second later the LCD is powered up, then displays “No Ethernet” (if it is not connected at this point)
