T1/E1
(Applicable to SmartNodes with integrated T1 or E1 WAN interface). The T1 or E1 ports are connected to
local exchange (LE). On this SmartNode series, the T1/E1 ports may only be used for data connections, and
not for voice (PRI). There are other SmartNodes that carry PRI voice interfaces. Type and pin outs may vary
depending on the manufacturer. In most cases, a straight-through RJ-45 to RJ-45 can be used to connect the
SmartNode.
DSL
(Applicable to SmartNodes with integrated DSL WAN interface). The DSL interface connects to the analog or
ISDN telecom line coming to your house. Depending on the country and type of installation, a frequency
splitter device may be inserted between the phone outlet and the SmartNode, splitting the DSL signal from the
phone signal.
Figure 33. Connecting the DSL cable
Hazardous network voltages are present in the T1/E1 cables. If you detach the
cable, detach the end away from the SmartNode or interface card first to avoid
possible electric shock. Network hazardous voltages may be present on the
device in the area of the T1/E1 port, regardless of when power is turned OFF.
To prevent damage to the system, make certain you connect the
T1/E1 cable to the T1/E1 port only and not to any other RJ-45
socket.
