COMMUNICATION NODE TYPE SIP-2 6/145
USER GUIDE - Rev. 3 (January 2018)
1 INTRODUCTION
1.1 GENERAL
The SIP-2 is a communication node designed to operate as a WAN router and a serial to IP
encapsulation device. Next, several examples of application are indicated.
The equipment can have one or two serial ports, one or two Fast Ethernet interfaces, and a
cellular 2G (GSM/GPRS), 3G (UMTS/HSPA) or 4G (LTE) interface.
The cellular interface admits dual SIM operation. It allows increasing the service availability
since it provides access to more than one operator, and the user configures how the
equipment will manage the WAN connection and the operator in use.
The equipment can also have two digital inputs, galvanically isolated, which can be
managed via SNMP. Upon request, it can also have two digital outputs.
As regards its installation, the SIP-2 can be supplied with a chassis suitable for mounting in
DIN rail or wall mounting.

SIP-2
COMMUNICATION NODE TYPE SIP-2 8/145
USER GUIDE - Rev. 3 (January 2018)
The SIP-2 can be managed locally and remotely, through a console or through a built-in
web server (http/https), SSH and Telnet server.
The SIP-2 also supports the SNMPv1, SNMPv2c and SNMPv3 protocols, as well as other
protocols and services such as NAT, DHCP, NTP and TACACS+.
The basic encapsulation function is the creation of a point-to-point connection, equivalent to
a direct connection between two serial devices, even when the actual data transfer is done
on a TCP/IP network.
The encapsulation function guarantees delivery of the data accepted in one of the serial
ports of an end, free of errors, and with unaltered order at the other end of the connection.
This function is usually called PAD (Packet Assembler-Disassembler).
The encapsulation function does not depend on the user data content. The equipment
admits two processing modes with the PAD function: direct or with packets.
SIP-2 equipment has the necessary procedures to perform an intelligent encapsulation so
as to process the data as higher level transmission units for a series of specific protocols of
Telemetry and Telecontrol. Thus, the operations on the data are not limited to their mere
transmission, but possible errors are identified, or the SIP-2 is capable of identifying
different data flows in a unique shared channel and of transferring them towards
differentiated destinations (demultiplexing).
Some of the supported protocols are IEC 60870-5-101/102/103, DLMS, GESTEL, DNP3.0,
PROCOME, SAP20, MODBUS, Pid1, Twc, etc.
Another additional characteristic for any of the encapsulator operations modes is the SIP-2
capability to offer the basic HAYES modem behaviour towards the client equipment, so that
the encapsulator point-to-point connections are made upon demand and with the
determined receiver by application or the client equipment. The operation in HAYES mode
is enabled separately for each one of the serial ports present in the SIP-2.

USER GUIDE - Rev. 3 (January 2018)
1.2 PORT INTERCONNECTION
In addition to the serial ports -which are called physical ports-, the equipment operates
with resources that are TCP/UDP connections, which are used to encapsulate data on the
TCP/IP networks; these TCP/UDP connections are called virtual ports, as opposed to the
tangible ports.
The equipment basic operation is the determination of the port characteristics, both
physical as well as virtual, and then establishes the “connections” between them; which in
practice sets the ends where the transfer of encapsulated data is done.
On the other hand, if the equipment has an optional WAN interface, there will be an
additional virtual port related to the GSM data call, in order to establish a connection
between said virtual port and a serial port.
Next, for a better understanding when approaching the SIP-2 configuration by accessing
the equipment HTML pages, there is a description of the main operations that should be
performed for the interconnection between physical ports (COM) and virtual ports
(TCP/UDP). It is advisable to perform the indicated operations in the order that they appear.
See chapter 5 for more detailed information about the configuration menus and their
parameters.
1. Configure the serial port parameters. For this, access the Serial menu (see section 5.4
for more information).
El Serial menu has two well differentiated sections: Physical and Logical.
In the Physical section, configure the basic operation parameters of the COM ports
(speed, data bits, parity and stop bits).
In the Logical section, configure either the encapsulation protocol or the use of an
encapsulation policy (policy-based option), and an identifier for it. The policy
configuration itself is done from the Policy submenu from the Flow menu.
The identification of the COM port, that is, the name, is done in the Physical Ports
section of the Flow menu configuration screen.

SIP-2
COMMUNICATION NODE TYPE SIP-2 10/145
USER GUIDE - Rev. 3 (January 2018)
2. Create and configure the parameters of the TCP/UDP virtual ports. For this, access the
Flow menu configuration screen (see section 5.16 for more detailed information).
The Flow menu configuration screen has two well differentiated sections. Physical
Ports and Virtual Ports.
Establish a different and unequivocal name for each COM port in the Physical Ports
section.
All the ports have the name serial0 configured by default and, therefore, it is essential
to assign a specific name to each of them.
On the other hand, if the equipment has a WAN interface, the Use autocli box should
be OFF, that is, not ticked, in the Datacall parameter so that the data call-serial
connection (GSM) is effective.
The operation of the datacall will depend on the services permitted by the operator,
especially in 3G and 4G networks.
Define the configuration of the virtual ports in the Virtual Ports section. For this, take
into account the following:
- The TCP connections may have two behaviours, active and passive. Active means
that the equipment will take the initiative as regards establishing the TCP connection. On
the contrary, passive means that the equipment will await for external connection
requests. The behaviours are complementary between them.
- The UDP connections do not need any prior establishment procedure; it is just
assumed that the receiver is configured to accept data in the indicated port. The UDP
connections do not offer end-to-end confirmation, or any guarantee as long as the
delivery sequence is the original one.
- It is usual to configure ports with values above 1000 since there are pre-established
ports for the use of general services in TCP/IP networks; thus, possible collisions are
avoided.
- The virtual ports may also have an assigned encapsulation protocol or policy,
although, as a general rule, just one encapsulation protocol or policy is assigned to a
sole end of each connection, understanding that it already includes a physical and a
virtual port as well. Thus, it is usual to assign the encapsulation protocol to the
physical port and leave the virtual port without a protocol, that is, with the raw
protocol option (default option).

SIP-2
COMMUNICATION NODE TYPE SIP-2 11/145
USER GUIDE - Rev. 3 (January 2018)
The inactivity time is the maximum period of time desired to maintain the
connection in the case of a lack of data, either in transmission or reception.
This parameter is configured at 0 by default, that is, the activity is not monitored
at the data level, which implies that the connection will be permanent regardless
of its activity. The parameter units are seconds.
- The active TCP connections have an On Demand parameter. Said parameter
indicates if the establishment should start just because the connection is configured, or
just when the equipment has encapsulated data to be transmitted.
The On Demand parameter is configured by default to establish the
communication start permanently. If the On Demand option is activated, the
duration of the connection will be established by the inactivity parameter, which
limits the connection to the activity periods.
3. Establish the connections between the ports through their identifiers. For this, access
the Connection submenu (see section 5.16.2 for more information) from the Flow
menu.
For an effective connection it is essential to correctly enter the name of the
identifiers established in the Physical Ports and Virtual Ports sections of the
Flow menu configuration screen. In order to avoid possible errors, it is advisable
to use the commands Ctrl.+C (copy) and Ctrl.+V (paste) instead of the keyboard.
Second, for connection to be operative, the CheckBox for the Enable parameter
should be active, that is, ticked.

1.3 VERSION WITH GW 104-101
The SIP-2 version GW 104-101 provides adaptive functionality between telecontrol entities
that communicate using the IEC 60870-5-3 protocol, although they use transport protocols
adapted to different media, in particular IEC 60870-5-101 on the remote side and
IEC 60870-5-104, using TCP/IP, on the control side. That is, the SIP-2 version GW 104-101
allows management of remotes type 101 from a control center type 104 TCP/IP in a
transparent way.
The functionality is known as Gateway 104-101 and, in this way, the equipment offers two
distinct behaviours: acts as a remote 104 from the point of view of the control center and, in
turn, acts as a control center 101 from the point of view of the remote terminal.
This functionality does not modify in any way the information units exchanged at the
application level (ASDUs) between the telecontrol remote and control centre, which are
established in IEC 60870-5-3. Therefore, despite offering the translation of the transport
layer, the user is the one that must establish the operation profile with regard the ASDUs of
the equipment.
