#Bytesizesignalling. WebWay fast polling, accurate availability measure per path+combined system. Low AV% alerts+diagnosis.
-
#Bytesizesignalling. EN standards=Dual Path system=99.98% availability for each remote monitored system.
-
#Bytesizesignalling. Checking GSM signal, PSTN line voltage, local router not enough. Must send 2way data constantly from/to premises/ARC.
-
#Bytesizesignalling. Accuracy. Poll once every 24 or 5 hours and you assume the network is working at other times. Not the case and risky.

This is a bit off topic but there's some important comments here. James..if you end up reading this you may want to put it somewhere else..if you excuse the expression! The reg makers are actually from within the Industry and nominated experts by the BSIA & BSI. These experts are normally employees of a manufacturer or some body within the industry. Each country nominates their own experts depending on the topic. Signalling is covered under EN50136 and my company is one of the nominated experts, CSL and Chubb have representation to. Each country, each supplier have their own agendas. They want to protect their manufacturers interest and the manufacturers want to ensure that their products meet the standard. What we end up with, is a minimum requirement, and this is what the EN standards are. What then happens, is that each country adds in it's own additional requirements that make improvements on those standards, and this is where product certification comes in. In Scandinavia it's DNV, in Germany its VDS, in the Benelux it's Telefication, France it's AFNOR. In the UK, we have the BRE and their LPS standards which actually cover more than just signalling. LPS1277 has been around for a long time, it's only Version 3 that has got some people hot under the collar. Personally, I agree totally with LPS1277 V3 and it is clear that if someone can disable a dual path system the ARC/Client etc should know very quickly. That is, within 3 and a half minutes on IP/GPRS & 11 Minutes for GPRS/PSTN. EN gives you upto 5 hours at Grade 4(!), 24 Hours at Grade 3(!), that is not good enough and WebWayOne has always argued as such. -
#Bytesizesignalling. Accuracy. To measure the availability of any transmission path you must poll quickly.
-
#Bytesizesignalling. Availability=the up time of the transmission path(s) at all times (not just the set period). Not a measure of “host”.
-
#Bytesizesignalling. WebWay service includes Roaming, home network barring and monitoring of the availability of the end to end GPRS route.
-
#Bytesizesignalling. WebWay antenna upgrade options include a tuned antenna and an extension antenna.

Over 40 guests visited Bletchley Park on 1st March for WebWay’s Insurance focused seminar. View presentations here: http://t.co/kdhvHP5S

#Bytesizesignalling. To send GPRS data you need: Signal strength, GPRS service registration and a working route to the destination.
-
#Bytesizesignalling. Roaming=SIM activated to access a no. of local networks. SIM has a “home” network+other networks if home not available.
-
#Bytesizesignalling. SIM=Subscriber Identity Module. Has: unique serial no, user no, security+ciphering, subscribed services+passwords.
-
#Bytesizesignalling. 3G? Faster download, but no difference in “sending” speed from site to ARC. 3G hardware=more expensive (today).
-
#Bytesizesignalling. GPRS, ideal for alarm transmission. Alarms=small amount of data. GPRS=fast enough+low cost per annum.
-
#Bytesizesignalling. GPRS=Global Packet Radio System. 2 way data service. Sends data outside the closed voice network to the internet.
-
#Bytesizesignalling. GSM=Global System for Mobile Communications. 2 way voice, interoperable across the world. Started 1991.Now>5 bn users
-
#Bytesizesignalling. WebWay integrates to Adpro FasTrace. Two way transmission with no inbound open ports. IP&GPRS.
-
#Bytesizesignalling. WebWay converts your Adpro FastScan from ISDN communications to IP. Optional images over GPRS.
-
#Bytesizesignalling. WebWay connects to Risco panels for SIA and UDL over IP and GPRS, encrypted.
-
#Bytesizesignalling. WebWay connects to all Guardall PX, QX and RX panels for SIA and UDL over IP and GPRS, encrypted.
