Smelling Salts

the fixed costs on a diginet line ..... does that include 2 points? or is it the rate per point ie rate per PC?

Best get your smelling salts out -- for when you get the price -- and COLLAPSE.

IF -- you read the links that moggie so kindly supplied then you would have your answer.

IF moggie would now be so kind as to explain the difference between SHDSL and the DIGINET offering we could ALL have a happy NEW year.

Telkom is getting like CyberSmart -- T&A -- but NO real info -- where WE can read about it.

HERE is a little hint to try and help you.

WHEN you see one of those "mobile" out of town ATM's -- ASK your self HOW they do it ???????????????????
and
NO thats NOT DSTV

You may however STILL need smelling salts.

VSAT?

and I did warn about the expensive bit!!!

 

[zambussi]

If you ever figure out a cost efficient way of doing this, please let me know.

Try this out
http://www.alnetsystems.com
Im running this system at work and the stream to my house is perfect. (i only have a 384k line at home)
If you download there program you can look and some demo sites. (zoom and rotate cams)

 

[xplicet]

i've done lots of these and the best way to go is to rather pay attention to the DVR software you are using and its compression standards.

If you have chosen a run of the mill system then it wont be designed to stream LAN/WAN video efficiently over low bandwidth. I have equipment that can stream realtime high res video under 50/Kbs.

Rather spend money on replacing the DVR or software and this will make good use of your ADSL line.

Why not just mention it here so it helps everyone reading this thread now or in the future, unless you are trying to make a sale? It won't be considered spam.

To much detail to get into. Choosing a DVR is like choosing a car, depends on budget and what you want from it. "You can have a very nice S class but it wont go off road". The same with certain types of DVR's & NVR's, some are designed for network streaming, some for high res record, some for anylitics etc

I am in the business so it is how i make my money, but check out the following brands for low bandwidth products;

Teleeye
Heitel
Servision
Geovision

Each one has pro's and cons. You have to be a dealer to buy. Dont buy Geovison over the inernet - most of it is pirate product.

Contact me for pricing and the benefits of each product.

IF moggie would now be so kind as to explain the difference between SHDSL and the DIGINET offering we could ALL have a happy NEW year.

Okay the difference.

I am running SHDSL at a number of client sites. What this is, is a copper wire that connects site A to the Telkom exchange and is wired in to site B. The only requirement is that its in the same Telkom exchange. So for example if both exchanges phone numbers are say, 021 849 9999 and 021 849 3833 they are probably at the same exchange, as in within the same radius. Telkom charges R380 p/m or there abouts for this line where you can, with say Zyxel routers get on average 1.5megs. I have managed to push a line to 5 megs but that is just because of the line attenuation. So essentially you are paying R400 for a leased line.

A leased line is pretty obviously a line from anywhere in SA from point A to point B and you pay for the amount of bandwidth you require. IE: a 128k line will set you back say R2500 and a 1meg line say R6500.

Fair enough, you have an agenda as I suspected. How hard is it really to lay it down and then ask people to contact you? Most people here volunteer their knowledge & effort for free. It's not a rule but we all get what we give

Fantastic info -- many thanks

Kinda puts Diginet in the shade now -- which is why Telkom keep it so SECRET :erm:


OK -- moggie -- Cat is out the Bag now

Questions ;

The connection would be synchronous ( by definition )

Does it run through a DSLAM -- I would assume YES

As it runs into the Telkom exchange I assume that it would be trivial for Telkom to provide INTERNET on this connection ( assuming you have the right client side equipment )

Any idea what the SAIX / TIS charge is on a line like this

I also assume that you can run all sorts of other things on this line as well -- multiplexed into the Telkom exchange infrastructure and then break out from there.

OK moggie -- the door is open now -- you can expand

Yes. Same speed both ways.

Does it run through a DSLAM -- I would assume YES

No, it does not come anywhere near a DSLAM. It either goes via the old Diginet infrastructure or the newer Martis infrastructure depending on what you order.

As it runs into the Telkom exchange I assume that it would be trivial for Telkom to provide INTERNET on this connection ( assuming you have the right client side equipment )

No. See it as a point-to-point circuit or leased line. It's got fsckall to do with internet. However it can and is being used to connect corporates or small businesses to the Internet. It's also used to interconnect private WAN infrastructure.

You can do whatever your hart desires on on a diginet or martis circuit. The Telkom exchange (Siemens EWSD or Alcatel E10) never comes into play here. The best option is still an E1 circuit or higher which offers the option of channelised circuits, you can take a 2MB/s circuit (or higher) and break it down to smaller 64kb/s circuits even though you only plug into one interface.

OK -- but do TIS / SAIX offer Internet service on this type of connection ( If you use them as your ISP )
and
What do they charge ????

alt -- What do other ISP's charge for this type of connection ???

Perhaps I need to phone Telkom and ask for the manual I still have a lot of questions. Why call it SHDSL -- DSL if it goes nowhere near the DSLAM ????

For instance what about the VPN offering for connecting private WAN infrastructure -- OK -- it is not the same -- but looks similar -- What infrastructure do they use for that ???

OK now to go and look up what CISCO say about the equipment you need

( I am sure one of my twelve routers will work :wtf: )

HHhmmmm

Seems I need to beg to differ ..........

1-Port G.SHDSL WAN Interface Card for Cisco 2600 Series and Cisco 3600 Series Routers

G.SHDSL is an ATM-based, multirate, high-speed (up to 2.3 MB), symmetrical digital subscriber line technology for data transfer between a single customer premises equipment (CPE) subscriber and a central office.

G.SHDSL is supported on the G.SHDSL WAN interface card (WIC-1SHDSL), a 1-port WAN interface card (WIC) for Cisco 2600 series and Cisco 3600 series routers.

The G.SHDSL WIC is compatible with the Cisco 6015, Cisco 6130, Cisco 6160, and Cisco 6260 Digital Subscriber Line Access Multiplexers (DSLAMs). The DSLAM must be equipped with G.SHDSL line cards that are compatible with the DSL service to be configured.

The G.SHDSL WIC supports ATM Adaptation Layer 2 (AAL2), ATM Adaptation Layer 5 (AAL5), and various classes of service for ATM.

Yes, you can get internet via Diginet or Martis which go up to 2Mb/s. There are other options when looking at higher speeds. Diginet or Martis however are not SHDSL services.

The line will always come from Telkom so you are going to pay them whatever it costs. Above and beyond that are the ISP costs you will have to pay each month as well.

Where do you see Telkom selling SHDSL services, I looked on their site but found nothing. I know Telkom has SHDSL internally but was never aware it was sold/used outside of Telkom. The SHDSL equipment is a totally separate dslam to the adsl dslam. With Martis & Diginet the term DSLAM does not even come into play.

The VPN offering works on the same principle. You need a router & leased lines, diginet, martis, E1, E3, ATM etc. What happens here is your traffic gets 'tunneled' if I could call it that across Telkoms IP Network. So instead of having a leased lined from say JHB to CT (you pay by distance!) you now get a leased line from your location to the closest POP. So now instead of having a single leased line you will now have two much shorter ones to a local point of presence which would be in JHB & CT.

The Cisco equipment needs to a simple serial interface. I would say forget about SHDSL for now unless telkom does actually sell such a service and where it's available.

Fair enough but I still want to see if Telkom actually sells SHDSL as it's a totally different kettle of fish compared to their other synchronous services.

 

[MidnightWizard]

The TRUTH !!!!!!

Well as you have seen in this thread there IS someone using this technology NOW TODAY.

To provide SHDSL Telkom may not even have to change anything -- ADSL is "cheap" SHDSL can also be 'CHEAP"

The point is that it would be a direct competitor with Matis / Diginet.

Who is going to pay R6,500 for something which you can get at R400 ???????

EVERY major Telkom exchange is a POP -- why CT or PTA ????

I just do not see why SHDSL cannot be offered as a product in the same way that ADSL is -- AND be provisioned for Internet.

You have seen that Cisco have ALL the subscriber equipment that one would need.

I await with bated breath and great anticipation for a sensible reply.

Keep in mind that it's a completely different type of service, it will get you to the exchange (like ADSL) and that's it. Once at the exchange you are still going to need another network to get you to distant locations for which leased lines will once again be required which like adsl would most likely have a contention ratio. Your diginet or martis links do not have contention ratios of 20:1 or whatever. You get what you pay for at the end of the day, granted leased circuits (like everything else) in this country is still expensive.

Sorry, you lost me here, not sure what you are talking about wrt to CT & PTA.

It will require additional capital investment for the equipment & backhaul network. Why roll out another network next to two existing ones (diginet & martis) that do the same job (+better) and SHDSL has limitations as mentioned above seeing it's only a access technology like adsl. General internet usage is not synchronous in nature for the majority of users and therefore adsl makes more sense. SHDSL would also require more bandwidth provisioning on the backhual seeing you no run at the same speed up and down which also affects your network design.

Secondly why roll out a cheaper service when you already have a capital investment in a better service which you can charge for what like seeing people have no other choices. Supply and demand.

I'm trying.
