BT NET LEASE LINE & UDM PRO

Hello,

we are awaiting our 200mbps BT NET Lease Line order to be fulfilled by BT which should be happening within the next Month or so.

i just want to clarify (Since BT are not helpful) that our setup will work.

we have a UDM Pro Router for which we want BT net to use WAN 1 on it as our primary line.

BT have said they are providing an NTE which i presume will be an ADVA FSP150CP ?

i want the connection to go from the NTE into the UDM Pro, happy to connect in what ever way will work, CAT6, DAC, etc.

can someone confirm this setup will work?

People on this forum are normally extremely willing to assist those with leased line questions but sadly due to a recent spate of fake leased line questions/posts from one individual using multiple fake accounts it is hard for people here to know if this is another one of these fake posts (this question is virtually identical to those previous fake posts).

If this post is genuine I would recommend you take the time to google the router in question as there is lots and lots of existing information out there that will answer this question.

I’m not being funny, I have tried Googling and looked through loads of info and can’t find my scenario. I have just joined and am looking for some help, I was told this would be the place to go. I have no idea about fake posts and no idea why someone would get entertainment from fake lease line posts. But I’m an IT Manager at a transport company. Search my name on Linked Inn you’ll soon find me.

If your not sure how it works I would always recommend going for a managed line rather than wires only

Sadly a few always spoil it for everyone else.

I haven't checked you out so the best advice I will give is speak with BT Net again and seek clarity on how the service will be presented to you, the UDM Pro Router supports both RJ45 (port 9 ?) and SFP+ (Port 10 ?) Wan inputs which can be configured as either WAN1 or WAN2. Personally because its only a 200Mbps service for now you are better off having it presented as RJ45 as it will be easier for you to test, diagnose issues and manage. If the UDM Pro Router already exists it may be as simple as plugging a Cat 5, Cat 6 or Cat 6a cable in between the BT Net service to the UDM Pro Router RJ45 WAN port and changing the IP configuration details to what has been supplied by BT Net.

I have a few clients who have BTnet Leased lines and all of them were supplied with usual Openreach ADVA FSP, fibre link form that to a BTnet supplied Cisco Meraki then Ethernet from the Meraki to your router.

The Meraki is not doing NAT, so you won't have double NAT, just set your UDM up as a static IP WAN1 with the IP, Mask and Gateway BT provide you in the handover doc

For what it's worth it's not the route I would have went, BTnet are usually very expensive, I'd say unless your rural if you're paying a penny over £300/Month or on a contract longer than 36 months try to stop the order now and look at other options. 200mbps on a gig carrier should be coming in at the £200-250/month mark - even less if CityFibre have infrastructure nearby.

CityFibre offer a product called Ethernet Flex, it's a gigabit circuit shared by up to 5 users (usually it's not shared at all!) so you get a minimum of 200mbps all the time but can burst up to a gig if no one else is on that split. That is only £199/Month and would be my go-to if it's available for you.

Leased lines is kind of "my thing" so if you want any pointers or want me to check what other options are available for you so you can try to haggle your vendors price down feel free to PM me anytime

Hey, thanks for the reply, annoyingly, we are extremely rural… 10 miles from the nearest Exchange. We’re in the middle of a woods in the middle of no where so they’re laying 15km of cable to us. It’s a pretty big project for them. Yeah there’s a huge upfront cost to it also, because of what we do it’s a must have at this point however so we have no choice and BT are the only company that would do it let alone cost wise… no one else would even bother. So I won’t have 2 firewalls or anything or any problems like that having the Cisco router in place? Is there an option not to use the Cisco router now djist use the UDM and the NTE?

Thankyou… hopefully it will work one way or another then!

Cheers for you help.

A direct internet access service is either provided as a managed service (with a router) or as 'wires only' without a router. So the first thing to be sure of is that this is truly a 'wires only' service and that BT will not in time be sending out to you a configured router when the service is near to going live.

If anything this helps you plan how you will manage and connect to the service but also physical space and power needs - wires only typically requires 2 RU of space (1 for the fibre tray/shelf and one for the Adva NTE). A dual power supply needed for the Adva too. Managed service needs another RU of space for the router.

If it actually is a 'wires only' provision then you will need to get the service configuration details for BT for the access. This is not only the IP addressing information but also any relevant VLAN information for the WAN port.

Finally - if this is wires only - in terms of physical connectivity double check with BT, but the usual default provision is a single-mode 1000BaseLX duplex LC interface that needs a matching pluggable on your router WAN interface. Its possible also to spec this interface to be 1000BaseT copper on the ADVA or indeed the multimode equivalent SFP pluggable as above. You just need to know which it is. Also DACs do work with ADVAs but they are not officially supported.

If you don't want the meraki at all you'd need to order "wires only" service, best bet would be speak to BT or check any documents they've sent regarding the service and they should list if it's wires only or managed
