Openreach NTE

Hi guys,

Friend of mine is having a leased line installed and has a data cabinet that is 400mm deep total.

The service provider has said that an Adva FSP150CP will be used, but after Googling, it appears that his cabinet may not be deep enough?

Should he just bite the bullet and get a 450mm?

Thanks.

Looking at some documentation, I see that an Adva FSP150/BT-/CP/GIG/2AC is shown as measuring 439 mm wide by 43 mm high by 269 mm deep.

The rack mounting brackets are described as "extended", as they set the unit further back in the rack to allow sufficient clearance for the front connections.

I don't have access to one mounted in a rack but comparing the above dimensions to a free-standing unit, I suspect that the above quoted depth of 269 mm must include the extended mounting brackets.

Edited to add: Looking in the definitive Adva FSP150CP User Guide I see --

2.2 Chassis

The chassis is an alloy steel case which houses the entire FSP 150CP system.

The dimensions of the chassis are:

� Height, 1U; 44mm
� Width, without mounting brackets; 433.2mm
� Depth, without International Electrotechnical Commission (IEC) and optical
connectors; 232mm

The depth allows the chassis to fit into a 300mm deep ETSI cabinet.

The chassis may be positioned as a standalone unit or it may be rack or wall
mounted. Adaptation to rack or wall mounting is possible by using mounting
brackets and separate removable mounting brackets are available for:

� 19� rack mounting
� 23� ETSI rack mounting
� Recessed rack mounting brackets are also available for 19� and 23� ETSI racks in
order to ensure that optical fibre bend radius is maintained when installed in
some cabinets with doors.
� wall mounting.

All brackets are designed to be screwed to the sides of the chassis and the screws
supplied have European threads.

Brilliant, thank you for all the info.

I have just found out that the from the front mounting rail, to the rear wall of the cabinet is 310mm so hopefully, all should be ok!

You are welcome.

Once the equipment has been installed and the service is up & running, perhaps your friend would like to comment on the noise situation! The FSP150CP has a pair of fans, which draw air in at the right-hand side and exhaust out of the left-hand side of the unit.

Ok i'll ask when it's in.

Thing is, it is being installed in a different room , so i don't think he will hear it from his office.

Ok NTE now installed and it is fanless.

The model is Adva Fsp150-GE102pro.

Thank you for the update. It's interesting to know that devices from the -GE100pro series are now being deployed.

I understand that the -GE102pro is the entry level (indoor) device of the series.

In terms of size, the -GE102pro is stated to be 44mm x 436mm x 211mm (HxWxD). One significant advantage being that they are, as you say, fan-less. There is, however, a finned heat-exchanger on the rear of the device and so caution should be observed if, at any time in the future, another device is added to the rack whose cables are routed to the rear, passing the -GE102pro's heat-exchanger.

He has just sent me a picture and all it has on the back is vent holes in the back with no fins as such.

Thank you for letting me know. In my haste I must have looked at the wrong document . . . Oops.

Standard access is defined as a single fibre/fibre pair connection between the NTE and the nearest BT Node. ... Secure access provides a single Ethernet interface presentation. Resilient access option 2 is defined as two standard access circuits routed between 2 different NTE and two different BT nodes.

The above post is possible pre-spam

Indeed.

Couldn�t get any further from the actual topic if they tried

I'm in the process of getting an Openreach leased circuit installed.

Do you happen to know the depth of the fibre shelf they install?

If its the shelf from your photo (above the Adva box) then looks to be about the same depth as the Adva NTE itself.

It's about that depth but then the fibre tubing comes out the back.

There's a wall mounted option if you don't want a 1U splice tray or want to save the rack space.

Thanks jpm. We're just about bang on with rack space. If its around 200mm deep (like most trays) then it should be fine as there's a 40mm twin wall duct with a draw rope, that will contain the blown fibre tube 'shotgun' from the building entry point (where theres another brick sized transition box). Theres enough room behind it for a decent bend/sweep into the back (or corner) of the splice tray.

Hi all, my first post here. We had a lot of servers in a room at work and connected those and all client PCs and Voip phones via BTnet 100/100 connection. However some time ago we moved servers to the cloud and I moved into what was the server room. Of all the remaining equipment in the room (switches, CCTV etc), the BT supplied Cisco 2900 series router and Avda FSP150CP NTE was by far the loudest devices in here. Too noisy to properly concentrate / hold a video call.

I recently purchased a spare fan assembly for the Cisco router and replaced the 4 fans with Noctua 60mm ones (NF-A6x25 PWM) and it is running so much quieter. It isn't pushing quite as much air as the supplied ones but this room is air conditioned and the air being pushed out isn't too warm - no warning lights etc. I think its fine.

Today I took the Avda box and gave it the same treatment with Noctua 40mm fans (NF-A4x10 FLX 40mm x 10mm to be precise). Same result - much quieter but.... there must be some impedance/fan speed sensing that has detected my mod so the critical / fans LEDs are lit - busted! I assume this gear is all managed so BT will see the fault. What I am hoping is they see the issue we have and replace the unit with a fanless model previously mentioned (or they just tell me to ignore the error).

I know we are not supposed to mod this stuff but we are well into our contract and I doubt we will be moving any time soon, so this equipment will be museum stuff by the time we don't need it. If they make me pay for replacement gear, fine - at least I can hear myself think now!

It doesn't matter how far into your contract you are, the NTE never becomes your property.

I'd be very surprised if the fan error was something that got passed to your ISP and then onto you for an appointment to be arranged.

Well that made my glasses steam up looking on that link at whats on it besides the first post

Thanks JPM, I understood that the equipment remains the property of BT, but previously we went from a local ISP (who resold Giffin Internet based connections) to BT. When the Openreach guy turned up he swapped out the NTE and router with exactly the same make/model and left theold stuff there. We kept a hold of it for years thinking they would want it back but no, so in the end I disposed of it environentally with another load of IT. Interestingly people are selling NTE on eBay - one I saw still had the BT asset tags on it!

There’s loads of ‘surplus’ BT / Openreach stores on eBay. Make of that what you will.

I've been left with two BT NTEs at home in the past and they seem to have no interest in retrieving them when the service ceases. I suspect they factor the entire cost of the equipment into the first year's contract.

First year they make you pay for it through ECCs....after a 3 year contract its a written down any way. Skip job or fleabay then.

If you want to get rid of them your provider can raise a request with Openreach to come and pick them up.
