Licensee Pre-requisites:
Equipment
In order to utilise internet bandwidth provided by Ipitomi IT, Licensees will have
to have equipment with a Ethernet networking facilities and be running an operating
system that supports TCP/IP. Avanta do not provide automatically allocated IP addresses
(DHCP). Licensees will need to purchase equipment that provides DHCP, or request
additional setup and configuration support from Avanta.
Security
Avanta provides the bandwidth without any security monitoring or restrictions therefore
responsibility for the security of a Licensee’s network and devices attached
to it lies solely with the Licensee.
Know-How
Avanta can arrange for the supply additional set up support including equipment
purchase and configuration at attractive rates through our Partner iHotdesk. It
should be noted that iHotdesk generally requires 72 hours notice for any services
required, due to ordering of equipment and possible commitments to other Licensees.
Installation
Avanta will endeavour to have Bandwidth services presented to the Licensee within
72 hours from the receipt of a signed order form. Times set out for upgrades to
existing services are subject to the increased speed being available on the existing
service type. If the faster service has to be delivered over a different medium
longer upgrade lead times may apply. An installation charge will apply for all up
or downgrades to the service. Note that this installation charge does not cover
any configuration of Licensee Equipment or network, but does include any patching
of services from the comms room to the Licensee Accommodation
Support
Should a Licensee encounter problems with their service, they should contact the
Business Centre for a fault resolution. Avanta support the service during Business
Hours (0830-1800, Mon-Fri), and will use all reasonable endeavours to have any service
problems addressed.
For all Licensee internal network or hardware support, Avanta offer a range of support
packages available through our partner iHotdesk.
Service Level Agreement
Availability
Avanta offer Service Level Agreements for the Service based on uptime of 99.5%.
The uptime is measured at monthly measurement periods from the 1st to the end of
each month. Any periods of downtime reported by a Licensee that continue in excess
of 20 minutes from the time logged with the Business Centre constitute downtime.
Should a Licensee encounter either 4 or more periods of downtime or an aggregate
total uptime of less than 99.5% within any measurement period they are entitled
to claim for the Service Credits set out below at whatever is the lesser performance
criteria.
Service Availability Credits
The Licensee may claim service availability credits of the following amounts in
the following circumstances:
|
Availability
|
Service Credit
|
|
< or = 99.5% uptime but > or = 90% uptime or 4 (or more) periods of downtime.
|
5% credit of Service Charges
|
|
< or = 89.9% uptime but > or =75% uptime.
|
10% credit of Service Charges
|
< or = 74.9% uptime.
|
25% credit of Service Charges
|
The credits may only be used as a credit against charges for further Services to
be provided by Avanta. They may not be redeemed for money or exchanged for anything
else. On termination or expiry of the agreement, any unused credit allowance may
be credited against charges for Services provided in the calendar month immediately
preceding termination. Any credit allowance which remains unused thereafter will
be lost.
Without affecting the Credit Process described below, if the Licensee wishes to
raise any problems or issues with the Services with Avanta, either party may escalate
those problems or issues up through the personnel named in the Escalation Procedure
section of the Cover Sheet.
Service Availability
"Service Availability" is defined as the ability of the Licensee
to exchange IP packets with the Network Services Supplier's designated gateway switch
via the provided switch port. Service Availability is measured by sending ICMP "echo"
requests from the Network Service Provider's designated gateway switch to the switch
at regular intervals and there shall be an "outage" if this measure
fails. The response to the ping burst confirms that the connection is still in place
and the service is still available.
Service interruptions caused by:
- failure of Licensee Equipment;
- scheduled downtime for maintenance and upgrade purposes, which Avanta will use reasonable
endeavours to ensure is kept to a minimum;
- network maintenance activities by the Network Services Supplier;
do not constitute outages of Service Availability for the purposes of calculating
service availability credits.
Credit Process
Service availability claims must be submitted to Avanta within one week of the end
of the calendar month in which the outage in question occurs.
The claim must contain the following information:
- Licensee name and Avanta Business Centre name at which the outages have occurred;
- date and beginning/end time of outage;
- brief description of the characteristics of the outage
- identification of the Services in respect of which the claim is being made and whether
such Services are Dedicated Leased Line Services or Shared Internet Access Services.
Claims must be submitted by e-mail to support@avanta.co.uk
Avanta will apply approved service availability credits to the Licensee's invoice
during the billing cycle following the claim approval.
Policy Change
Avanta will notify the Licensee of any changes to this Service Availability Schedule
which Avanta may make in its absolute discretion from time to time provided that
Avanta shall for the term of this agreement provide a service comparable to the
service outlined in the initial Service Availability Schedule.
*Allocation of RIPE/Pubic addresses is subject to official approval of the requirement
which must be made by means of an IP Address Allocation Justification Form.
Frequently Asked Questions
Why is this service more expensive than my home broadband connection?
The service is delivered on a 100MB fibre optic connection, using premium Cisco
routing and switching equipment to enable Avanta to deliver many different types
of Bandwidth and IP configuration to all of the different clients (and types of
client) in the building. This has to be available in 72 hours and sometimes faster
to meet the short term needs of clients in the offices. This type of infrastructures
is unfortunately not cheap, neither is the provision of the support structure to
enable us to respond quickly to client issues. We don’t keep you waiting on
the phone to India!
What is the set up charge for?
This covers the one-off cost of providing the internet connection, it is subject
to VAT. It is levied on a per company basis and will not be raised again (unless
the client changes to another type of Internet connection or upgrades/downgrades)
. Note that this installation charge does not cover any configuration of Licencee
Equipment or network, but does include any patching of services from the comms room
to the client accommodation. There are no set up fee for phones, so expansion/contraction
by the client will not result in any further set up fees.
How is the Service Presented?
Avanta provides 1X RJ45 switch port for the DATA connection from one of our Cisco
switches placed in the building comms room. There may be more than one comms room,
but we will generally provide the service to a switch in the room that can connect
with the floor ports in your offices.
How do I get the connection to my Office?
The data connection can be patched directly to your office, but if you are using
more that 1 PC, we advise you to connect the service to a hub or switch in the Comms
Room, unless you plan to use a wireless router in the office. The ports on the hub
are then connected to the ports in the comms room that connect to the floor ports
I your office.
What is a RIPE/Public Address?
A RIPE/Public Address is a globally unique number that identifies a device on the
Internet. If you want someone on the Internet to connect to you or one of your servers,
then you must tell them your public address (also known as your “real”
or “external” address). If you request a public/RIPE address, you need
install a piece of equipment that performs NAT. Most Routers and Firewalls today
can provide NAT for you. If you require more than one public/RIPE address, you will
need to fill in an IP address
allocation justification form.
If you plan on using a VPN to access a remote network, we strongly recommend utilising
a RIPE address, running on your own firewall. The reason being that when you access
the internet over an internal range (please see internal range [link to internal
range FAQ]), you will utilise something called a NAT table. NAT is similar to the
receptionist in a large office. A Client calls the main number to your office, which
is the only number they know. When the client asks for you, the receptionist checks
a look-up table that matches your name with your extension, and then forwards the
caller to your extension. However, the NAT lookup table (NAT table) is constantly
being updated, so it frequently reaches a point of saturation, and, consequently,
needs to be cleared.
All clients/users with internal ranges are routed via these tables to access the
internet and by their technical nature fill up. You could say that the receptionist
has too many names to compare against, rendering the look-up table useless. In order
to prevent this, our ISP flushes these tables every 1-2 hours depending on usage
and, once they are flushed, all connections requiring a constant transfer of information
will be lost, including VPNs.
What equipment do I need?
If you need to connect only one computer, you will only need an Ethernet cable,
however, a firewall is also recommended (or a router with a basic firewall). If
you have to connect more computers, for the public (RIPE) address you will need
a router and possibly a switch (depending on the number of computers), or just a
switch if you don’t require a public (RIPE) address (again, a firewall is
recommended as well).
Do I need a Firewall?
Yes, you are advised to buy a hardware firewall or configure a software firewall
on all your connected Pc’s. None of our internet connections are protected
by firewalls.
Do I need an ADSL modem?
None of our internet connections requires an ASDL modem. They are ADSL/SDSL in name
only to represent their contended nature.
Do you provide servers to relay email (SMTP servers)?
Yes, we offer two SMTP servers: smtp.pitcore.com and post.viatel.net.
You can utilize any of the two.
What is DHCP?
DHCP is a protocol used by networked computers (clients) to obtain IP addresses
and other parameters such as the default gateway, subnet mask, and IP addresses
of DNS servers from a DHCP server. The DHCP server ensures that all IP addresses
are unique, e.g., no IP address is assigned to a second client while the first client's
assignment is valid (its lease has not expired). Thus IP address pool management
is done by the server and not by a human network administrator.
Will an internal IP address be automatically assigned?
None of our data ports can provide DHCP at present, though this is planned for the
near future. This will mean either configuring all of your PCs to use a static address
that we provide, or (better), please purchase a Router or Switch that can provide
DHCP to all connected devices. We can recommend the following devices, which can
be bought from our preferred supplier:
Up to 4 Users:
Wired –
LINKSYS Firewall/router + 4 port switch
