Terminating Resistors
100ohm Terminating resistors are required across the transmit and receive wire pairs at each end of the S-bus.

For IP Office 4.2+, individual ports of an IP500 BRI daughter card can be switched to So mode. This is done by setting the Line Sub-Type to S-Bus in the IP Office configuration. In this case, terminating resistors must be added at the IP Office end in addition to those at the other end of the S-bus connection.

Addition of the necessary termination at the IP Office end can be done using an IP500 BRI So Converter Cable (700458649). This short (25cm/10") cable includes both the necessary terminating resistors and the cable cross-over.

Many ISDN terminal devices includes terminating resistors. If this is not the case, 100ohm (+/-5%) resistors must be connected across the receive wire pair and the transmit wire pair in the junction box immediately before the last ISDN terminal on the S-bus.
