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 disconnect the piezo ringer otherwise you hear a "click" each time the LEDs are turned on or off • 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.

Using the SIPB 5132-SP Telephone with the PSB 2163 in IOM-2 TE Mode

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, 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 disconnect the piezo ringer otherwise you hear a "click" each time the LEDs are turned on or off
• 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.
