2. Technical Configuration
2.1.
Physical Connection
The new service will be delivered by fibre optical cable directly to customer sites.
The fibre optic path is optimized for high throughput through the use of DWDM /
CWDM coloured optics.
This approach allows higher bandwidth services to be delivered over the same fibre
optic pair. The DWDM / CWDM equipment is provided by Cube Optics and is
electrically passive.
The network service access point at the Network Layer will typically be a pair of Cisco
3560’s Layer 3 Switches.
The Cisco devices provide the option to have the delivery of the site hand-off as:
•
•
•
Copper 1Gb/s
Single Mode Fibre 1Gb/s
Multi Mode Fibre 1 Gb/s
Customers can select which hand-off interface they require at the point of ordering the
service.
The Physical SAP service connection is delivered;
•
•
•
over copper, using the standard RJ45 physical socket, auto MDI/MDI-X or;
over single mode fibre, using the standard LC(PC) duplex interface, or;
over multimode fibre, using the standard LC(PC) duplex interface.
The Logical SAP service logical interface is;
•
•
•
over copper, at 1Gb/s only 1 – IEEE standard 802.3ab / 1000baseT or;
over single mode fibre, at 1Gb/s only – IEEE standard 802.3z /
1000baseLX/LH, or;
over multi mode fibre, at 1Gb/s only – IEEE standard 802.3z / 1000baseSX.
AND
•
over all of the above interfaces, 802.1Q tagged frames to distinguish VLANs.
1
Note – even though the copper interface only supports the 1Gb/s speed, in accordance with the standard Section 28D.5 Extensions
required for Clause40 (1000BASE-T), the interface must be permitted to auto-negotiate rather than being fixed configuration.

2.2.
Physical Cabling and Connectivity
The equipment that is installed within the client site includes transmission and IP
(Internet Protocol) equipment. As mentioned elsewhere in the document, the actual
location of the equipment may vary depending on what is already installed at a
customer site and what accommodation is available at the site; however the actual
connectivity between the IP devices doesn’t really change.
Production Connectivity
•
Multimode Fibre from the transmission equipment connects to each Cisco
3560-E on port GigabitEthernet 0/25 using an SFP connector (this is shown as
light Green on the diagram).
•
The two 3560-Es connect together using UTP (CAT6) cable up to a maximum
of 100m total length from GigabitEthernet 0/24 to GigabitEthernet 0/24, this is
effectively the resilient path which is used in case of the failure of one WAN link
(this is shown as black on the diagram below).
•
The client LAN interconnect is connected to GigabitEthernet 0/27 on both Cisco
3560-Es. Depending on what type of interfaces has been requested by a
customer (Single Mode Fibre, Multimode Fibre or Copper) an appropriate SFP
adapter is installed (this is shown as Red & Purple on the diagram). If copper is
selected it is highly recommended that only CAT6 or CAT6A cabling is used.
This connection provides VLAN tagged frames to the LAN.
Management Connectivity
In order to provide the highest levels of reliability and supportability, a management
connection to the device is used outside the normal production path to the device, as
follows:
•
•
UTP (CAT6) up to a maximum of 100m total length is connected between port
GigabitEthernet 0/1 of one 3560-E to the management interface of the other
3560-E, (this is shown as yellow on the diagram below).
An asynchronous roll-over (not crossover) cable is placed between the Console
ports of the devices, (this is shown as light blue on the diagram below). Where
this cable length is over a specified length, line drivers may be required.

Customer IP Addressing
Customers will have the choice of using their own registered addressing, or
alternatively the Exchange will assign blocks of registered addressing for use.
If a customer is using their own registered IP addressing, the following rules apply:
•
•
•
•
•
•
The customer provided IP address subnets have to be a public range and
registered to their company e.g. on RIPE database
The registered subnet for production has to be a minimum of a /26
The registered subnet for Customer Testing has to be a minimum of a /27
A contiguous subnet has to be provided for each services i.e. Production and
Customer Testing
The subnets should support growth within the customer network to avoid
running out of host addresses.
The subnet is dedicated to a Single customer SAP and cannot be used
elsewhere on the LSE network or via another customer SAP.
The following VLAN’s and subnets will be made available to customers and will be
assigned for different services as shown below:
VLAN 950
Subnet: Public /26
Unicast: Legacy Production & MIT Product
Multicast: Legacy Production
VLAN 951
Subnet: Public /27
Unicast: Legacy Test & MIT Test (All traversing B-Leg)
Multicast: Legacy & MIT Test (All traversing B-Leg)
VLAN 952 / 953
Subnet: Public /30
Unicast: None
Multicast: MIT Production & HVS
The diagram below illustrates this further:
Please note that the production registered IP addressing can only be configured for
production services, and likewise the testing registered IP addressing can only be
configured for testing services.

Millennium Exchange Services
Unlike the current LSE multicast streams, the new service will feature active/active
primary (A Stream) and secondary (B Stream) of market data being delivered at the
same time.
Both streams will contain identical market data however the source and group IP
Multicast addresses will be different.
The two streams of data will be sourced from the Primary and Secondary LSE data
centres and therefore there will be a generally consistent time differential between
receiving the A and B stream.
10
The A stream is optimized using the shortest path through the fibre network and the
minimum number of devices to pass through, which means that the A Stream will
normally be delivering the market data faster than the B Stream. Under certain
circumstances, the location of the site and other factors may determine the B stream to
be faster, particularly when the network is operating on the resilient leg of a
transmission or IP Network path. It is therefore not recommended to assume that the A
Stream is always delivering the most recent data.
Each feed will have its own source IP address with different multicast destination
addresses; all of these addresses will be registered.
2.6.
TradElect/Infolect Services
The existing Infolect multicast services will be delivered using the current approach and
addressing.
The primary Extranex path will be used to connect to the Exchange’s Primary Data
centre, with the backup path connecting to the Secondary Data Centre.
Unlike Millennium Exchange services, the legacy TradElect/Infolect services do not
offer dual ‘A’, ‘B’ feeds.

3. Timescales and Pricing
For the standard resilient service in “ON net” locations in and around London provided
with a diverse pair of Verizon circuits, Verizon will charge £22,000 per installation with
an annual charge of £84,000.
Where carrier diversity is required COLT will be used, and for a resilient service in and
around London provided using Verizon and COLT, Verizon will charge £23,500 per
installation with an annual charge of £84,000, which is the same as the pricing for the
existing 100mb service.
Service for customers located OFF net or outside the UK will continue to be priced on a
site by site basis and will be confirmed individually for existing customers depending on
carrier availability.
There is a minimum 1 year contract followed by a 3 months rolling notice period.

5. Frequently Asked Questions
(FAQ)
How do I order Extranex 1Gb?
Customers can request order forms by emailing:
Extranex1gb@londonstockexchange.com or calling +44(0)20 7797 3232
Can the services be delivered using two carriers to increase resilience?
During the planning process, the route of the fibre path is considered extensively with
respect to resilience and latency. The optimum path will be proposed which could be a
12
dual linear service from one provider or multiple protected or unprotected services from
multiple providers.
We already have CAT6 / CAT6a structured cabling between the locations of the
Primary and Secondary SAP switch cabinets, can this cabling be used to reduce
the need to install new cables?
If the cabling meets the required specification it may be possible to be used, this will be
assessed during the site survey. If you would like to use structured cabling please
identify the specification of the cabling, length between cabinets and commissioning
results, prior to site survey.
13
Appendix – Equipment Installation
Process
Prior to the installation of the SAP equipment at a customer site, a survey will be
carried out to ensure the environment is suitable. The surveying engineer will verify that
the location the equipment is to be installed is suitable and has the correct facilities,
such as space and electrical outlets.
In some cases all of the equipment will be located in one rack and in other cases
equipment may be distributed over more than one location, depending on the current
infrastructure at the site. Passive cabling is required between the Primary and
Secondary LAN devices, so a cable route may have to be agreed during the site
survey.
The Cube Optics device is provided as a 1U rack mountable chassis unit with modular
filter units that plug into the chassis. Depending on the layout of the site either one or
two filter units can be installed in each chassis, catering for one or two lines.
Flashwave Wavelength Services Access Platforms provide the overall control and
management of the physical fibre path.
