Topic # 153812 8-Oct-2014 18:41

We are about to migrate from Woosh wireless to Actrix ADSL + phone line.  The building is wired CAT5, but there is no PABX - there is a single line and all phones  (5) are running in parallel.    I'm after some advice:

The phone pair arrives in the building downstairs in the warehouse.  At some point it will be connected to an Actrix-supplied Netcomm ADSL modem/wireless router.  The best location for this would be upstairs (for good wireless coverage) but that will involve the ADSL + phone signal travelling upstairs over CAT5.

Is this a good idea?  My feeling is that we want to minimise the distance between the incoming phone pair and the modem for optimum speed, so I'm thinking that I should try that first (ADSL modem downstairs) in case wireless coverage we get is adequate anyway.    

The other thing I'm unclear about is what we need in the way of line filters.  I assume these are lowpass filters needed to keep the ADSL hash out of the phones.  If I have the ADSL modem downstairs at the point where the phone line enters the building, can I get away with one filter, with all the phones in the building paralleled and connected to the building side of the filter?  Or do you need one filter per phone regardless?

SO many questions...

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.



If you are posting regarding DSL speeds please check that



- you have reset your modem and router



- your PC (or other PCs in your LAN) is not downloading large files when you are testing


- you are not being throttled by your ISP due to going over the monthly cap



- your tests are always done on an ethernet connection to the router - do not use wireless for testing



- you read this topic and follow the instructions there.



Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:



- Your ISP and plan



- Type of connection (ADSL, ADSL2, VDSL)



- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)



- Your general location (or street)



- If you are rural or urban



- If you know your connection is to an exchange, cabinet or conklin



- If your connection is to a ULL or wholesale service



- If you have done an isolation test as per the link above



Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.



A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.



I recommend you read these two blog posts:



- Is your premises phone wiring impacting your broadband performance? (very technical)



- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

Get a dedicated master filter installed where the line comes in to the building - a run of cat5 from the filter to the modem will then have negligible difference

Whoooooaaahh.  There's obviously much more to this than I first imagined!

Thanks for your advice.  How much confidence can I have that the guy/gal who fronts up to do the install will have the inclination to recommend and install what's best?  Will this person be from Actrix?  Chorus?  The GCSB?

I'll do a bit more reading.  Some good links here.

You can always get separate ADSL modem and wireless AP if you want them in two different locations.

Which I may end up doing, it's just that the ADSL modem also has wireless and comes with the plan.
