External S-Bus power supply
External S-Bus power supply
Many ISDN telephone handsets require that 40 VDC power be supplied via the S-Bus connection. In other
words, they have no separate or built-in power supply. In general point-to-multipoint ISDN BRI NTs supply
line power to the S-Bus. Point-to-point NTs connected to a PBX in general do not supply line power.
If line power is not available from the NT, but required for connected terminals, the PM-BRI-EXT S-Bus
Phantom power supply can be used.
Table 41. PM-BRI-EXT S-Bus 40V power supply
Item:
Phantom Power Supply; PM-BRI-EXT
Voltage Specifications:
Input 230VAC, Output 40VDC
The PM-BRI-EXT power supply unit is equipped with a transformer
that is specially designed for S-Bus line power. The use of a general
purpose DC power transformer may cause equipment damage.
If you use a Phantom power supply other than that supplied by
Patton Electronics Co., you must ensure that it conforms to ITU
I.430 Section 9.7.3.2.2. which specifies that the maximum cur-
rent delivered shall not exceed 200mA.
