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.
