Internal ISDN S0 Line Connection
The ISDN S0 Bus on the KX-TD280 and the KX-TD286 can be
used as internal S0 bus. Each port can be used as either external or
internal ISDN S0 Lines. Some System Programs are required to
use the S0 bus as internal ISDN S0 lines beforehand.
Connection
Use 4-pin plugs (included) to connect ISDN S0 lines. A single plug
is able to connect one ISDN S0 line. Mis-connection may cause the
system to operate improperly.
1. Re-arrange telephone wires in reverse order of the plug.
2. Insert the plug into a ISDN S0 port on the unit.
