Routers - General Description
Siemens ITS (Poole) provide and support three types of routers, namely a 3G/4G Router, xDSL
Route and Instation Router for use in customer networks.
This chapter outlines these devices and provides an overview on their use.
2.1.
MuLogic RSA ADSL
This type of router can be used to connect IP based equipment to a customer network using
an ADSL “Broadband“ Connection. The ADSL line will allow a connection to the Public Inter-
net, and the router can provide a IPSEC VPN (Virtual Private Network) tunnel to another Rout-
er to allow the WAN (Wide Area Network) connection back to the customer LAN (Local Area
Network). For details please refer to 667/CI/99107/000.
2.2.
PROROUTE 4G Router
The current router is the PROROUTE H685 4G (667/1/99110/000), which can be used to con-
nect IP based equipment to a customer network using a Mobile Phone connection (3G or 4G
GSM). Wireless connections of this type are not normally as reliable as using wired communi-
cations solutions and are not always suitable in some locations or for certain applications. If
in doubt, please contact the Engineering department in Poole for clarification.
The PROROUTE H685 4G (667/1/99110/000) Router also allows IPSEC VPN tunnels to be con-
figured for secure connections across the public Internet, these settings would be provided
by the Customer or Poole Engineering department.
2.3.
Connection Types
There are two types of equipment connections used in Siemens ITS. The first is the ‘transpar-
ent’ connection and the second is the ‘VPN’ connection.
2.3.1.
Transparent Connection
In this type of connection the STRATOS Outstation, or ST950 controller, will be the VPN cli-
ent. Therefore any communications interface only needs to act as a transparent ‘pipe’ to and
from the STRATOS Outstation/ST950 Controller.
Safety of
Licences
The STRATOS Outstation/ST950 Controller needs to be supplied with the appropriate certifi-
cates in order to enable connection through to the STRATOS Instation.
