TSP: Agreement template for 'clip no screening' / 'special arrangement'

by Benoit Panizzon

Yo! out there! I know this list is more about ISP than TSP, but as we mostly do both and an informal inter-TSP discussion list does not exist (or did I miss it?) I'm addessing the swinog list. We had a couple of our telephony customers asking us if we would do clip-no- screening (swisscom calls this special arrangement'). Pass on every caller-ID the customer is sending. Well, there are use cases where this can be desidered, like a PBX doing a manual transfer after answering the call, thus opening a second call leg but with the wish, that the number of the original caller is being transmitted. But! We already see a lot of abuse with invalid or fake number from other TSP with no propper outbound screening. So we would like to make our customers singn an agreement which hopefully would prevent such. Swisscom has no such template. How about the other TSP? Is there one I could use as a template for our agreement?

Fun with Fiber

by Andre Oppermann

The Netflix guys wiring up a fully loaded ASR9010 with 118 single mode fibers: http://www.youtube.com/watch?v=tyb-nnRNwfw For those who don't know yet, Netflix is an online movie rental company and uses so much bandwidth that they had to push out their own CDN boxes to ISPs and IXPs. Their CDN boxes are almost stock FreeBSD 9.1 based, contain some 35 HDDs at 4TB plus a couple of SSDs and push about 15Gbit/s *each* during the evening hours. They are limited by HDD (seek) bandwidth. -- Andre

Hi & Wireless connection in Les pléiades (above Vevey)

by ESL - Francois Tiffreau

Hi all, As it is my first post, I'll introduce myself a bit. I'm Francois, the netadmin from ESL Education SA. We have ~50 remote offices across the world, linked to our HQ in Montreux. For now we use only IP-Plus from Swisscom (100/100) and SDSL links in our remote offices. We'll soon (2014) upgrade everything, like starting working on multihoming in Montreux and we'll see how to make things better for the remote offices. We notably have latency issues (200+ms) with latin america and asia. So I'm not a network operator, but would greatly benefit from your inputs. Feel free to contact me off-list or send me a SMS when you're around Montreux to have a quick coffee. I just have a quick question while we're at it : I have a contact that sometimes work from home in Les Pléiades (above Vevey). It's in the mountains, so as you might imagine, the DSL from Swisscom is far from sufficient. I'm sure there's alternative solutions such as wireless links to the Mont Pèlerin (direct sight), or Rocher de Naye (not too far) ? Maybe satellite ? We're talking about less than CHF 200.- / month. If anyone provides this or can give me some contacts, that would be great. Thanks in advance, Have a great weekend, Francois -- Francois Tiffreau | Senior IT Systems Engineer ESL Education SA Head Office - Switzerland Grand-rue 50, CP1204, 1820 Montreux t +41 21 962 88 80 | m +41 79 216 37 37 skype esl.francois http://www.esl-education.org Please consider the environment before printing this e-mail This e-mail message may contain certain confidential and privileged material for the sole use of the intended recipient.
