SmartNode 5550 & 4150 Series User Manual D • Port pin-outs
FXO port
The FXO ports use an RJ-11 connector with 6 positions. The middle two positions 3 and 4 are used according
to
table 14 on page 67.
Note
Pins not listed are not used.
ISDN BRI (NT/Net or TE/User) ports
The BRI phone port uses an 8-pin RJ-45 connector (the pin-out shown in table 15 )
.
Note
Pins not listed are not used
Note
All pins between the even and odd ports are connected during power failure.
(BRI 0/0 and BRI 0/1 | BRI 0/2 and BRI 0/3 | BRI 0/4 and BRI 0/5 | BRI
0/6 and BRI 0/7). Fallback relay operation (depending on Model. Only for
models with /R in product code):
•
When the unit is not powered, the fallback relay connects pins 3,
4, 5, and 6 of the net and the user ports (fallback) together. This
enables you to place calls to the PSTN even if the unit is powered
down.
•
Line power applied to the Line port is fed through to the Phone
port at all times and independent of the fallback relay’s status.
Note
On each ISDN BRI port in TE mode, it is possible to switch on ISDN line
power per software. The total amount of power is 4W. If a ISDN BRI port is
switched to NT mode, the ISDN line power is turned off.

DO NOT insert an RJ11 connector into an RJ45 socket. An RJ11 connector, which has 4
or 6 pins (see
figure 22
on page 69) can permanently damage the 8 pins in an RJ45
socket, causing data connections to fail. This can especially be an issue with WAN inter-
faces (SDSL, ADSL, etc). If it is necessary to connect an RJ11 connector with an RJ45
port, an RJ11-to-RJ45 adapter must be used.
