If you are unsure of whether to terminate the line or not, contact your ISDN service provider or your authorised Allied Telesis distributor or reseller.

Warning Do not attempt to change any jumpers on the NSM while the switch or router is connected to a power supply or a live network. Disconnect the mains power supply, any redundant power supply, and any cable attached to the ISDN ports of the NSM. Dangerous voltages may be present on some parts of the NSM board, even if the switch or router is powered off.

The BRI interfaces use RJ-45 connectors. Table 3 shows the pinout of the BRI interfaces.
