| IP |
Internet protocol.
A protocol enabling information to be sent over
private or public networks to different manufacturer's
equipment and applications. |
| Broadband |
An always on,
high speed connection to public internet or private
networks. |
| ADSL |
Asynchronous
Digital Subscriber Line - the technical term for
broadband. |
| PSTN |
Public Switched
Telephone Network. Your existing analogue telephone
line. |
| BT 21CN |
The BT PSTN
analogue network is currently being upgraded to
their next generation IP infrastructure called
BT 21st Century Network, or 21CN. Within the next
five years BT will switch off the analogue network
and move to a fully integrated IP system, transmitting
voice and internet traffic over a common system. |
| GPRS |
General Packet
Radio Service - a global standard for connecting
mobile devices to the internet or private networks.
GPRS is supported by Vodafone, Orange, O2, T-Mobile
etc across the UK. |
| ARC |
Alarm Receiving
Centre. The secure premises where signalling data
arrives and is presented to operators for action.
ARCs must comply to BS5979 and have NACOSS approval. |
| CIE |
Control, Indicate
Equipment. The alarm panel. |
| End to end |
From the CIE
communications interface to the annunciation equipment
at the ARC. |
| Annunciation
Equipment |
The receiving
equipment for your signalling system, located
within the ARC. |
| Polling |
A poll is an
encrypted and sequenced message, transmitted by
the signalling system and acknowledged by the
receiver. A loss of the polling sequence during
a specified time constitutes an alarm. |
| Encryption |
The ability
to protect data from being read or edited during
transmission. Encryption should be site specific
with a key for every site, just as you have a
key for every locked door. Ask your signalling
provider if they encrypt per site, or whether
one key unlocks all. |
| Substitution |
A method of
replacing messages or a signalling device with
another. WebWay 2424 protects all messages from
replay and all devices from replication. |
| Remote Engineering |
Alarm transmission
systems that rely on Pins also rely on a separate
modem for upload/download. This incurs cost for
the installer and end user, as well as provides
a relatively insecure “back door” to
the alarm panel. WebWay 2424 allows access to
the alarm panel for remote engineering using password
protected access and an encrypted communications
path. There is no need for a dial up modem at
the installer premises or in the alarm panel. |
