Description of QE20 Fibre Networking
A fibre networked VIGILANT QE20 system uses an IP (Internet Protocol) network to
send data and voice (Speech, WIP, paging console, background music) between
QE20 panels.
The VIGILANT Panel-Link IP Bridge (PIB) is used to provide data networking
between panels as well as one-to-many VoIP audio streaming. A third-party
Analogue Telephone Adaptor (ATA) (Cisco ATA 192) is used to convert voice
signals into VoIP and provide one-to-one VoIP calls between nodes as well as act as
an audio source for the PIB VoIP proxy functionality. The PIB’s Ethernet connection
is wired via the ATA (it has two Ethernet ports working in bridged mode), so a
communications fault is generated if the ATA fails, is powered down, or loses its
configuration.
The VIGILANT VIF0907 module (VIF) is used to interface the QE20’s Speech and
WIP audio signals into the ATA, as well as set up and monitor the call functions of
the ATA.
A third-party Ethernet Switch and fibre optic converter (Moxa EDS-405A) sends the
IP traffic over the fibre ring. It monitors the ring for a break, and when one is detected
it automatically sends the packets in both directions, so all other nodes receive the
information. The ring break signal is output by a fault relay in the switch, wired to the
PIB so that the QE20 can generate a fault condition.
Each QE20 panel must include an RS485 Network Module to control networking
operation and provide the data and audio interface points for the Fibre Network Kit.
This general arrangement is shown in Figure 1. The highlighted items are included in
the QE20 Fibre Networking Kit.
Figure 1 –General Arrangement of QE20 Fibre Networking Kit
The fibre network can be used to extend QE20 networking over long distances or
between locations where it is not economic or practical to install the multiple cable
pairs needed for a QE20 RS485 copper network (plus extra pairs for background
music and/or paging console audio when required).
The fibre network can also be used to distribute paging console audio and/or
background music. Additional VIF modules, ATAs, and PIBs may be required.

For the QE20 two different Fibre Network Kits are available – depending on the type
of fibre used.
•FP2024 FP, QE20 FIBRE NETWORK KIT, SINGLE MODE
•FP2025 FP, QE20 FIBRE NETWORK KIT, MULTI MODE
Typically, multi-mode fibre will allow up to ~3km between QE20 panels, whereas
single mode fibre will extend to ~40km between panels.
Generally, the whole ring will be run in the same fibre type, but it is possible to use
different types of fibre. This will require additional equipment at those QE20 panels
that need to support both types of fibre – at least an additional fibre switch will be
needed.
The fibre network kits are sufficient for voice communication with up to 31 other
QE20 panels. If the QE20 needs to simultaneously send Speech and/or WIP All-Call
to more than 16 other QE20 panels, then additional PIBs and other equipment will
need to be added. Formulae for determining the quantities required are described in
this manual and implemented in QE20Cost.
If background music and or paging audio must be transferred around the network,
then additional equipment will be required. For each pair of additional audio signals a
VIF and ATA is required, plus an additional PIB will be needed for every 31 remote
nodes receiving the audio.
The QE20 fibre network cannot be used to increase the existing limits of a QE20
network or a Panel-Link network regarding the maximum number of nodes supported
by a QE20. But multiple QE20 networks could be contained on one large fibre
network.
Programming of each QE20 site configuration for fibre networking is mostly the same
as RS485 networking. However, configuration is required for the ATA dialling plans
to enable VoIP calls to be set up around the network. Additionally, the PIB, ATA,
Fibre Switch and VIF will require configuration. This is described in this manual.
A Fibre-Copper Bridge QE20 allows the connection of an RS485 copper network
onto a fibre ring. This could be used to convert the main fibre network into a local
building RS485 copper network for wiring to other QE20 panels within the building.
The bridge QE20 includes a second RS485 Network Module to provide the PA and
WIP Audio signals for the copper network (the first Network Module handles the
main fibre network signals).
The Fibre-Copper Bridge QE20 provides audio bus joining so that it may hold
separate Speech and WIP conversations with the QE20s on its copper segment,
while other conversations are taking place on the fibre network.

2. Operation of Fibre Network
Data Communication
When a QE20 panel sends data it may be sent as a packet to the specific QE20 (SID
number) that needs to receive it, or as a broadcast to all QE20s. With fibre
networking each message is sent by the RS485 Network Module to the PIB, which
looks up a table to identify the IP address of the destination QE20 SID and then
sends the message to the PIB at that IP address using UDP. The receiving PIB
passes the message on to the QE20 Network Module, which forwards it to the
Controller to process. For broadcast messages, the PIB will send the message to
each PIB that it knows about (unless filtering is programmed).
The PIB can have a pre-programmed table of SID numbers and IP addresses, or it
can automatically build this table from messages it receives from the QE20 panels
and PIBs on the network.
The Moxa fibre switch takes care of sending the UDP and VoIP packets around the
fibre ring, especially when the ring is broken.
Audio Streaming – PIB VoIP Proxy
When Speech and WIP ALL-CALL is sent on the network, it quite often needs to be
sent to many places at once. For example, a Speech announcement to the whole
network would require the speech audio to be sent to every other node. This
presents quite a burden on the sending device, and as the ATAs do not support
streaming of audio to more than 4 devices, something else needs to do this.
The PIB can be configured to stream audio to up to 31 other nodes. This function is
called PIB VoIP Proxy in the PIB. Each PIB can have up to four streaming channels
configured. When it receives a streaming request on a channel it will attempt to
make a VoIP call to a pre-programmed IP address to get the source VoIP data
stream (usually the ATA in the same panel). Any data the PIB receives is then
streamed to all the remote devices that have connected to the channel. This way
each PIB can fan out the streaming audio to 31 other nodes. By having multiple PIBs
connect to the original source ATA, or daisy-chain from one to another, the single
audio source can be fanned out to a virtually infinite number of destinations.
Speech Audio Communication
The following is a simplified description of how Speech audio is distributed in a QE20
fibre network. In the event that something is not working, it may be useful to track
the actual operation against the description below.
2.1.1 Speech
When a Speech announcement is initiated from a QE20 that involves distribution of
the speech to other QE20 panels on the fibre network the following happens in
sequence: –
1. The user at the QE20 selects one or more zones for Speech. This panel is
hereafter referred to as panel A.

QE20 Fibre Networking User Manual Document: LT0732
Page 2-10 24 May 2023 Issue 1.0
2. Panel A transmits which zones are selected for speech to the other QE20
panels via the PIB.
3. Each other QE20 maps panel A’s zones to its own zones, and if any do map
to local zones, it waits for the PTT signal to become active, then instructs its
VIF module to dial the phone number configured to reach panel A.
4. The ATA uses the dialled phone number and its configured dial plan to
determine the IP address and UDP port number for the VoIP proxy (PIB) or
ATA at panel A.
5. The ATA at each such panel makes the call to the VoIP proxy or ATA at
panel A.
6. On receiving the first incoming call the VoIP proxy then calls the ATA at
panel A.
7. The ATA at panel A signals the VIF it has an incoming call by ringing, and
the VIF answers the VoIP call.
8. The ATA at panel A transmits digitised audio to (1) the VoIP proxy which will
then distribute this to each of the ATAs at the other panels that have joined
the same call or (2) the ATA at the other panel.
9. The operator makes the speech announcements to the occupants of the
zones selected.
10. The operator at Panel A releases the PTT button or deselects zones for
speech.
11. This is transmitted across the data network to the other QE20 panels.
12. The other panels see that speech is no longer required for their zones and
so terminate their call to the ATA or VoIP proxy at panel A, which will then
terminate the call it made to the ATA at panel A once all remote nodes have
disconnected.
WIP Audio Communication
2.1.2 WIP Call initiated by User Interface
When a WIP call to a field WIP at a remote panel is initiated on a QE20, the following
happens in sequence: –
1. The operator at the QE20 initiates the call by pressing the WIP call button.
This panel is hereafter referred to as panel A.
2. Panel A transmits the pressed WIP button number to the other QE20 panels
(via the PIB and fibre networking).
3. The other QE20s determine if the button maps to one of its WIP buttons and,
if so, sets the button to the ring state. If that button maps to a field WIP then
the WIP module rings that WIP circuit.
4. When the field WIP is answered (off-hook), the remote panel informs Panel
A of the fact via the data network.
5. Panel A sees the called WIP is off-hook and instructs its VIF module to dial
the phone number configured to reach the remote panel.
6. The ATA at Panel A uses its configured dial plans (and most likely speed-
dial) settings to find the IP address of the ATA at the remote panel.
7. The ATA at Panel A makes a VoIP call to the ATA at the remote panel.
8. The ATA at the remote panel signals the incoming call by ringing the VIF,
which answers the call.
9. The ATAs at panel A and the remote panel transmit digitised audio between
each other (both ways) using RTP.

Document: LT0732 QE20 Fibre Networking User Manual
Issue 1.0 24 May 2023 Page 2-11
10. The two parties talk to each other.
11. The operator at Panel A disconnects the call by pressing the WIP call button
again.
12. Panel A transmits the call-on-hold condition to the remote panel via the PIB
and networking.
13. Panel A terminates the VoIP call.
Note: if the call is terminated by the remote party hanging up their WIP phone, refer
to the final steps of the next sequence.
2.1.3 WIP Call Initiated by Field WIP
When a field WIP is picked up, the following happens in sequence (assuming the call
is answered at a remote QE20): –
1. A field WIP is picked up. The QE20 (panel or amprack) this WIP connects to
is hereafter referred to as panel A.
2. Panel A maps the field WIP to its local button and sets this flashing.
3. Panel A transmits the WIP button to the other QE20 panels (via the PIB and
IP networking).
4. The other QE20s map panel A’s WIP button to their WIP buttons, and if the
calling WIP button maps to a local WIP button rings the master WIP and
flashes the appropriate WIP LED.
5. The operator at the QE20 panel answers the WIP call by pressing the
flashing call button. This panel is hereafter referred to as panel B.
6. Panel B sets this WIP button to the connected condition.
7. Panel B then transmits the “connected” condition for the WIP button to panel
A via the PIB and fibre networking.
8. Panel A maps this WIP button to its local WIP button and sets it to the
connected condition, along with the field WIP.
9. Panel B instructs its VIF module to dial the phone number configured to
reach panel A.
10. The ATA at panel B uses its configured dial plans (and most likely speed-
dial) settings to find the IP address of the ATA at panel A.
11. The ATA at panel B makes a VoIP call to the ATA at panel A.
12. The VIF at panel A sees the incoming ringing and answers the VoIP call.
13. The ATAs at panel A and panel B transmit digitised audio between each
other (both ways) so the two parties can talk to each other.
14. The WIP connected to Panel A is hung up.
15. Panel A transmits the WIP button idle condition to panel B (via the PIB and
IP networking).
16. Panel B receives the idle condition for the WIP button, extinguishes the WIP
LED, and terminates the VoIP call.
17. The ATAs hang up.
Note: if the call is terminated by a user at the QE20, refer to the final steps of the
previous sequence.
2.1.4 WIP All-Call
This works in a similar way to Speech – refer above. When a remote QE20 receives
an All-Call from another QE20 and it is configured to accept this All Call, it will
instruct its VIF module to ring the phone number configured for All Call at the calling

SID. It does not wait for any WIPs to be answered. The ATA maps the dialled
number to the IP address and port of the VoIP Proxy or ATA at the calling panel and
makes the call.
2.1.5 Inter-QE20 WIP Call
This works in a similar way to the User Interface-initiated call described above. There
is no on-hold condition with inter-QE20 ECP calls. Note it is not possible to hold
simultaneous calls with the ECP WIP and field WIPS at the same QE20.
Additional Audio Signal Communication
2.1.6 Background Music
Panels that receive background music over the fibre network will make a (usually
permanent) VoIP call to the panel that distributes the music. If the source of the
music can change (e.g., it is controlled by a paging console), then the VoIP calls
made will depend on the current music source.
2.1.7 Paging Console Audio
Panels that receive paging announcements over the fibre network will make a call to
the panel that sources the paging console audio, i.e., the panel which connects to
the paging console(s).
If there is more than one panel with a paging console, then the VoIP calls will be
made to the panel with the active paging console. Otherwise, VoIP calls can be
made always to a fixed panel. In both cases, the QE20 script should be
programmed to make the VoIP calls when required, i.e., when paging is in use.
Network Data Requirements
Please refer to the information in the PIB User Manual (LT0519).
In addition to the Ethernet traffic requirements listed in LT0519, you must allow for
the VoIP traffic. This is approximately 80 kbps for each possible simultaneous
connection. For a standard call this data is transmitted both ways, while for a
streamed connection (e.g., Speech or WIP All-Call), data is one-way from the source
to each destination. For example, if a panel can be sending speech to 6 other nodes
and a (two-way) WIP call could be in progress at the same time, the total traffic
would be 6 x 80 kpbs + 2 x 80 kbps or approximately 640 kbps.
If additional audio signals are transported over the network then the data
requirements of these will need to be added in.
Ports / Protocols Used by the ATA and PIB
2.1.8 ARP
ARP is required to map IP addresses to MAC addresses.
2.1.9 ICMP
ICMP is supported to the extent that replies are sent to PING requests.

2.1.10 TCP
TCP Port 80 provides a web server that is used for configuration and diagnostic
monitoring of the ATA, PIB and fibre switch. Access to these web servers is highly
recommended for service personnel, as many diagnostic details are provided by only
these web servers.
2.1.11 SIP
SIP over UDP is used by the ATA and PIB VoIP proxy to set up and take down calls.
By default, the ATA uses UDP ports 5060 and 5061. The PIB VoIP proxy uses UDP
ports 5060 to 5063 by default.
An ATA that wants to initiate a call to another ATA or PIB VoIP proxy will send a SIP
INVITE message. The remote VoIP device may then send a TRYING / RINGING
response, and if the call is answered by the remote VIF, will then send an “OK”
response. The two VoIP devices will then send audio data each way using RTP. At
the end of the call, one of the VoIP devices will send a BYE message.
2.1.12 RTP
RTP over UDP is used by the VoIP devices to transfer digitised voice data between
QE20s. The ATA uses UDP ports 16384 to 16482 by default. The PIB VoIP proxy
uses UDP ports in the range 16000 to 19998 inclusive.
Router / Firewall / VLAN Configuration
Dedicated fibre networking should be used for the QE20 network.
If this is not the case, then the evacuation network must be configured into a
separate VLAN so its traffic is isolated from that of other users of the network. Refer
to PIB User Manual (LT0519) for further information on this.
Routers/Firewalls within the IP network must be configured not to block any
addressed (i.e. non-broadcast) TCP, UDP, SIP, and RTP packets to / from the PIBs
and ATAs on the network. Refer to section 2.7 for the protocols / ports used by the
ATA and PIB for VoIP communication, and to the PIB User Manual (LT0519) for the
protocols / ports used by the PIB for Panel-Link networking.
Note, SIP sometimes does not work well with systems employing Network Address
Translation (NAT) because the ATA embeds its IP address in the message it sends
to the other connecting ATA. If NAT is employed, special programming of the SIP
ATAs, PIB, and the router providing NAT will most likely be needed.
