Peter,

That's really helpful - thanks!

I like the sound of the 6850 and a port-to-port layout - it's similar to the 
way we're used to dealing with Openreach EADs.  The only battle then is to get 
them to run a 24 core fibre patch panel from their ODFs into each of our access 
racks!

VLAN'ing a 10gig port is a good idea, but our access stack is based on Cisco ME 
3600 switches only have two SFP+ ports, so we can't really afford one just for 
a Virgin interconnect.

I'll wave the clue stick at them and see what happens.

Thanks again!

C

Hi.

The baby Alcatels are a PITA to put it mildly – when they first started using 
them they would only provision one uplink so we’ve got loads with no more than 
10 x 100meg ccts on. They do do a side by side shelf so you can get 2 into 1U 
if you weren’t aware.

However on a brighter note, point them at 6850s – these are 24 port gig 
affairs, so you get 11 x gig uplinks to them and 11 circuits to you, in a port 
to port configuration (with a mountain of wasted Metnet ports and DC fibre of 
course). They will also vlan on them (as they will on the smaller ones with gig 
ports) so you can “discuss” how much commit on an uplink you are happy with. We 
usually cap at 5-600meg per uplink with 100 on gig type customers and even with 
upgrades in the last couple of years have only had to move a couple to new 
uplinks.

They (VM) will also do 10gig and vlanned, which they still stick via an Alcatel 
and present a single SFP+ port to you. The reason for the Alcatel is at E2E 
testing time (they still insist on it) they put a gig port into the vlan they 
are testing at your core end and perform a full E2e).

We’ve gradually moved to 10gig handoffs as port to port presentation in TH and 
such is a pain in the butt – although in our own DC use a mix of port and vlan 
handoff.

Hope that helps, and a serious clue stick is needed in their direction IMO..

Subject: [uknof] Virgin Demarc Boxes [Was: virgin media delivered leased line 
fibre service - their CPE and us, and expected speeds.]

Sorry to change the subject a bit, but this thread has reminded me of something 
I thought I might ask:

Some of our PoPs are filling up at an alarming rate with Virgin Alcatel demarc 
boxes that only have one or two ports used.  This is mainly because we have a 
number of circuits that are on 1Gig bearers, and the Alcatel boxes only have 
two gigabit ports (one NNI and one UNI), so typically a 1G customer circuit 
will take up 1U of rackspace (nevermind a separate fibre cross connect to the 
Virgin ODF).

Having said that, strangely we just had a new circuit installed into one of our 
PoPs that ended up terminating on a LightningEdge LE-311.  At least that box 
has 4 gig ports - but it's an absolute monster compared to the Alcatel.

The old Pandatel card+chassis based solution was a lot better suited to gigabit 
circuits, because you could get 15 or 16 cards in a 4U chassis (much like 
Openreach EADs), but unfortunately Virgin don't offer this anymore.  We've 
suggested they give us a Transmode box, but I think they only deploy those for 
wavelength services, and wouldn't want to waste them on Ethernet circuits 
(despite the volume of circuits we give them).

 - Does anyone know of any other EDDs Virgin have been known to use that might 
have 10G uplink?
 - Does anyone take L2 services from Virgin on a VLAN based delivery?  I know 
they do this, but I wonder if it's just going to have the same density issues?

Any shared experiences here would be helpful in our 'guided suggestions' to our 
Virgin account manager!

Thanks,

C

Are they giving you a layer3 service? Odd they can't use the SPF port
on the Cisco as that cpe has three gig interface on board.
yes, just a regular business service

They would always use an Alcatel box as the NTU currently, agreed there is some 
level of madness but it's the way they do things I believe for monitoring (?!). 
They moved to Alcatel a few years back and had some fun with learning how to 
commission, this was after 3-4 years of Lightning Edge.

For MIA if they use BGP multihop they often put an ME3[4|6|8]00 switch in the 
way as well as the Alcatel,  for lesser bandwidth's it's Alcatel + generally 
Cisco 2900 ish

Cheers
