Safety when working with electricity
•This device contains no user serviceable parts. The
device can only be repaired by qualified service person-
nel.
•Do not open the device when the power cord is con-
nected. For systems without a power switch, and without
an external power adapter, line voltages are present
within the device when the power cord is connected.
•For devices with an external power adapter, the power
adapter shall be a listed Limited Power Source. The
mains outlet that is utilized to power the device shall be
within 10 feet (3 meters) of the device, shall be easily
accessible, and protected by a circuit breaker in compli-
ance with local regulatory requirements.
•For AC powered devices, ensure that the power cable
used meets all applicable standards for the country in
which it is to be installed.
•For AC powered devices which have 3 conductor power
plugs (L1, L2 & GND or Hot, Neutral & Safety/Protective
Ground), the wall outlet (or socket) must have an earth
ground.
•For DC powered devices, ensure that the interconnecting
cables are rated for proper voltage, current, anticipated
temperature, flammability, and mechanical serviceability.
•WAN, LAN & PSTN ports (connections) may have hazard-
ous network voltages are present, regardless of whether
the device is powered ON or OFF. PSTN relates to inter-
faces such as telephone lines. FXS, FXO, DSL, xDSL, T1,
E1, ISDN, Voice, etc. These are known as “hazardous net-
work voltages” and to avoid electric shock use caution
when working near these ports. When disconnecting
cables for these ports, detach the far end connection of
the SmartNode first.
•Do not work on the device or connect or disconnect
cables during periods of lightning activity.
•If one has reason to open the chassis or case, then the
precautions mentioned above shall be followed. This
includes both the warnings relating to disconnection of
the input power, and the warnings relating to the discon-
nection of WAN, LAN & PSTN ports.
In accordance with the requirements of council directive 2002/96/
EC on Waste of Electrical and Electronic Equipment (WEEE),
ensure that at end-of-life you separate this product from other
waste and scrap and deliver to the WEEE collection system in
your country for recycling.

General observations
•Clean the case with a soft slightly moist anti-static cloth
Dieses Gerät ist NICHT für den Anschluss an das Telefonnetz (PSTN) bestimmt
und auch NICHT dafür zugelassen. Es ist nur für den Anschluss an Endgeräte
beim Kunden vorgesehen.
•Das Gerät entält keine austauschbaren Komponenten und ist vom Benutzer nicht zu
öffnen. Bei Systemen ohne Netzschalter und ohne externes Netzteil liegt Netzspan-
nung im Gerät an, wenn das Netzkabel angeschlossen ist.
•Bei Geräten mit externem Netzteil muss das Netzteil die Anforderungen an eine zuge-
lassene Stromquelle mit begrenzter Leistung erfüllen. Die Steckdose, die für die
Stromversorgung des Gerätes verwendet wird, sollte höchstens 3 Meter vom Gerät
entfernt und leicht zugänglich sein sowie durch einen den örtlichen regulatorischen
Anforderungen entsprechenden Schutzschalter abgesichert sein.
•Für mit Wechselstrom betriebene Geräte muss sichergestellt sein, dass das verwen-
dete Netzkabel alle gültigen Normen des Landes erfüllt, in dem es eingesetzt werden
soll.
•Für mit Wechselstrom betriebene Geräte, die 3-polige Netzstecker haben (L1, L2 u.
GND oder Phase, Neutralleiter u. Schutzleiter), muss die Steckdose geerdet sein.
•Für mit Gleichstrom betriebene Geräte muss sichergestellt sein, dass die Verbindung-
skabel für Spannung, Strom, erwartete Temperatur, Entflammbarkeit und mecha-
nische Wartbarkeit geeignet sind.
•WAN-, LAN- u. PSTN-Ports (Anschlüsse) können unter gefährlicher Spannung ste-
hen, unabhängig davon, ob das Gerät ein- oder ausgeschaltet ist. PSTN bezieht sich
auf Schnittstellen wie Telefon, FXS, FXO, DSL, xDSL, T1, E1, ISDN, Voice, usw. Diese
sind als „gefährliche Netzwerkspannungen“ bekannt. Um einen elektrischen Schlag
zu vermeiden, muss in der Nähe dieser Anschlüsse mit Vorsicht gearbeitet werden.
Werden Kabel von diesen Anschlüssen getrennt, zuerst das Kabel am anderen Ende
herausziehen.
•Während eines Gewitters darf nicht am Gerät gearbeitet werden und es dürfen keine
Kabel angeschlossen oder vom Netz getrennt werden.
In Übereinstimmung mit den Anforderungen der Richtlinie 2002/96/EG über Elektro- und
Elektronik-Altgeräte (WEEE) muss sichergestellt sein, dass Altgeräte von anderem Abfall
und Schrott getrennt werden und dem Sammel- und Verwertungssystem für Elektro- und
Elektronik-Altgeräte in Ihrem Land zum Recycling zugeführt werden.
Do not stack multiple SmartNode devices directly on top of one another, and do not place
items on top of the device. If you will be installing equipment above the SmartNode device,
leave at least 2 inches (5 cm) of clearance between the devices.
Furthermore, leave at least 2 inches (5 cm) to the left, right, front, and rear of the SmartNode
device for proper ventilation.

SmartNode 5531 Overview
The SmartNode 5531 Enterprise Session Border Controller (eSBC) and Integrated Access Device (IAD) (see
figure 1) comes with built-in security features such as SIP TLS, SRTP, stateful firewall, and secure provisioning
to protect the LAN networks from fraud strikes out of the Internet. For survivability use cases the BRI ports
can be used for local PSTN breakout. The BRI ports can be used to connect legacy equipment to any VOIP
network as well. Like any other Trinity device, the SN5531 comes with the built in WEB Wizard for ease of
use.
Figure 1. SmartNode 5531 eSBC and IAD
The SmartNode 5531 consists of several models: see the complete SKU list on the corresponding product page
on www.patton.com.
All the SN5531 models come equipped with two 10/100/1000 Base-T Ethernet ports and with 2 up to 8 BRI
T0/S0 ports.
The SmartNode 5531 eSBC/IAD performs the following major functions:
•Four up to 16 channels of Voice over IP and local voice switching via 2, 4 or 8 ISDN BRI S0/T0 ports. Each
port can be switched between NT and TE per software.
•For each ISDN port in NT mode a Phantom power supply can be switched on. The total delivered power is
4W.
•Depending on the model, a fallback cut-through relay between ISDN BRI ports 0/0 and 0/1 electrically con-
nects the NT and TE port in case of power failure and enables life-line calls to the public ISDN network
(PSTN-supplied ISDN line must be used).
•Standard compliant VoIP in accordance with SIPv2 protocol.
•Supports 4 SIP to SIP calls and can be license upgraded to a total of 256* (additional cost)
•Internet access and IP Routing with IP Quality of Service (QoS) support for mixed voice and data traffic.
•SIP registrar, SIP TLS, and SRTP are available on all SN5531 models.
•USB 2.0 host port for 3G/4G modem support, which can be used for Survivability applications as a data
backup link.
