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.

Ten seconds after powerup D1, D2, D3, D4, D53, D52, D51 flash in sequence.

One second later the LCD is powered up, then displays “No Ethernet” (if it is not connected at this point)
