3. Typical System (Overview)
 The SwitchplusIP™ Voice Communication System provides operators the
ability to interface with radio, telephone and intercom services.
 The system is comprised of the following basic components:
- Operator Positions
- Communication Server Units (CSU)
- Radio Interface Units (RIU)
 The system is monitored and managed by the Maintenance Server Unit (MSU)
 The basic system components are interconnected via Ethernet and managed
by dual redundant (optional) LAN Interface Units (a.k.a. IP Switches).

3. Typical System (Overview)
 The SwitchplusIP™ Network Topologies (Overview)
- Single (non-redundant) LAN
▫ This model is usually reserved for small systems such as a mobile dismount system where
down-time is not a critical factor.
- Dual Redundant LAN
▫ C4i preferred network configuration prior to Product 7.0
▫ All equipment is connected to two (2) independent LANs (i.e. LAN A and LAN B) where all data
is duplicated on each LAN.
- Active-Standby LAN (a.k.a. Main / Backup)
▫ C4i preferred network configuration post Product 7.0
▫ All equipment is connected to two (2) LANs (i.e. LAN A and LAN B) however data is not
duplicated on both LANs; instead LAN A is used unless the connection fails then reverting to
LAN B (or standby connection).

Advanced Maintenance Presentation
3. Typical System (Overview)
 Single (non-redundant) LAN
- In a Single LAN topology, all equipment is connected to a single LAN, as the name
suggests.
- Should any piece of equipment’s connection to the LAN fail (such as an OIU, RIU or
CSU), its resources are lost as there is no other network communication path for the
unit.
▫ Therefore if an OIU loses its Ethernet connection (such as the port is blocked at the switch or
the cable is disconnected or broken), that operator position is lost.
▫ For an RIU, its radio resources are lost.
▫ For a CSU, if the system only contains one CSU, all radio and telephony services are lost;
however, if the system contains two CSUs, the secondary CSU will manage radio and
telephony resource connections.

3. Typical System (Overview)
 Single (non-redundant) LAN
- It is recommended that if a Single LAN topology is used, a very high availability IP
switch is used to minimize the likeliness of a switch port failing.
Note: If the switch completely fails, all services are lost.

3. Typical System (Overview)
 Dual Redundant LAN
- All equipment is connected to two (2) independent LANs (i.e. LAN A and LAN B).
- Data is sent on both LAN A and LAN B.
- In this situation, should any piece of equipment’s connection to LAN A fail, its
resources are not lost as it will still have a network connection on LAN B.
Note: In order to maintain a dual-redundant topology between remote locations or
additional sites (for multi-site systems), two communication links must be used and
two switches are required at each location or site. A single communication link can
be used to connect the locations or sites using routers but this will make the routers
and link a single point of failure.

3. Typical System (Overview)
 Active-Standby LAN
- All equipment is connected to two (2) LANs (i.e. LAN A and LAN B).
- Data is not duplicated on both LANs, instead LAN A is used unless the connection fails
then reverting to LAN B (or standby connection).
- In this situation, should any piece of equipment’s connection to a switch fail, its
resources are not lost as it will still have a network connection. Audio may be lost
temporarily as the equipment switches from using LAN A to LAN B. The impact is
minimal.
Note that in order to maintain a dual-redundant topology between remote locations or
additional sites (for multi-site systems), two communication links must be used and
two switches are required at each location or site. A single communication link can
used to connect the locations or sites using routers but this will make the routers and
link a single point of failure.

3. Typical System (Overview)
 Communication across a WAN
- SwitchPlusIP™ has the ability to access radios at the same site and across multiple
sites using a communication link or WAN.
- If resources other than the SwitchPlusIP™ system use the link care must be taken to
ensure system stability.
- The following points must be considered:
▫ Bandwidth – Varies with system size, usage, recording methodology and network topology.
▫ IP Plan – Devices that are not part of the SwitchPlusIP™ system can not share the same IP
addresses or use the same multicast ports.
▫ Network Isolation – Need to verify that devices outside the system are blocked from writing
to or monitoring anything on the IP Plan.

3. Typical System (Overview)
 Network Isolation
- If resources other than the SwitchPlusIP™ system use the same network
infrastructure measures may need to be put in place to ensure system stability and
harmony.
- Virtual LAN
▫ VLANs provide network segmentation by treating VLAN members as through they are on a
separate physical network.
▫ They provide data security through this network segmentation (or isolation).
▫ They can span across WANs allowing physically separate sites appear as local.
▫ Simplify traffic flow management across shared networks.

 Network configuration to be wary of…
- Network Structure and impact of incorrect configuration
▫ If the current network is setup in an Active-Standby configuration, installing a node (such as
an RIU or OIU) in the Dual Redundant (LAN A / LAN B) or Bridged configuration will not have
any drastic affects on the system however that specific node will not behave as expected;
However
▫ If the current network is setup in a Dual Redundant (LAN A / LAN B) configuration, installing a
node (such as an RIU or OIU) in the Bridged configuration will cause unwanted network loops.
This may cause the entire system to fail.
- IP Switch configurations
▫ Correct protocols must be setup depending on network topology (e.g. Spanning tree protocol,
LANs, etc).

 Upgrading a spare part or system (software roll-out)
 RIU ETX (Linux) and CSU Upgrade
- The RIU and CSU upgrade process requires an intermediary to serve the software
upgrade (which is an operating system image that includes the SwitchplusIP™
application suite).
- This intermediary is known as the NUS or Network Upgrade Server.
- The NUS runs as a virtual machine on the MSU. It is a unix based VM that takes the
operating system image from the MSU and transfers it to the destination RIU ETX or
CSU.
- The only manual interaction with the NUS (other that starting it) is when you have to
reconfigure an RIU ETX (or CSU) for a different position (or site), like a spare part and
you do not know the units MAC (Media Access Control) Address.

 RIU ETX (Linux) and CSU Upgrade
- Network Upgrade Server
▫ The VM serves DHCP (Dynamic Host Configuration Protocol) requests and therefore there
cannot be another DHCP server within the system.
▫ The NUS serves DHCP requests for approximately 60 minutes after the VM has been booted
and therefore the NUS should only be running during an upgrade event.
▫ The NUS is on the release disc and installed onto the MSU as part of the MSU installation
procedure.
