The basic steps to be performed are quite simple:
• Open the telephone case
• Replace the PSB 2165 with the PSB 2163
• Switch the DIP-switch according to table 3
• Close the telephone case
Normally, the PSB 2163 is not only used in handset mode but also as a speakerphone,
therefore the speakerphone test mode is of interest, which indicates the internal status
of the speakerphone with the help of two LEDs. As table 1 shows, with the PSB 2163
this internal status information is outputted at the PZ-pins (pin 27, 28). Inside the
SIPB 5132-SP telephone, the piezo-ringer is connected to these pins. With regard to the
schematic of the telephone, the following steps have to be performed for a proper
connection of the test LEDs:
• Adjust the volume potentiometer for the piezo ringer to the lowest volume or
• Connect pin 27 (PZ2) with the gate of (e.g.) T4
• Connect pin 28 (PZ1) with the gate of (e.g.) T5 (see schematic)
Now the pins SA, SB (pin 5 and 4), which are normally connected to the gates of T4 and
T5, must always be programmed as inputs (default) to avoid a short circuit at the PZ pins.
Of course, pin 4 and 5 can also be disconnected. Note, that pin SD is used for hook
switch detection and therefore T2/D1 should not be used for the test LEDs.
