CPE/NID options

Mon Nov 27 14:50:39 UTC 2023

For those carriers that do not mind, they have already accepted the cost that comes to a truck roll and may pass the cost onto the customer depending on the result. Where as there are a number of carriers like Cogent, Colt, Comcast, Cox, Crown Castle, Lumen, Zayo, are capable of testing the circuit without a truck roll.

Around here, Spectrum uses an Adva for demarc and it can not do rfc2544 testing.  They will unplug the Adva and plug in the techs' mobile unit (Viavi I think).  VZW/Tmo/Sprint/etc don't seem to mind.

The problem with using switches as a CPE device is the lack of RFC2544 (or equivalent) testing, and monitoring of the complete circuit with TWAMP. Both of which are used to ensure compliance with an SLA.

When you say fiber, is it Ethernet?  If you just want layer 2 and a media converter, Mikrotik is a super good answer.

Hi Ross,

I've found these Mikrotik devices to be excellent and reliable:

CRS310-8G+2S+IN: 8 x 2.5G copper ethernet ports, 2 x SFP+ cages, rack-mountable. Uses a single DC barrel-jack. https://mikrotik.com/product/crs310_8g_2s_in
CRS305-1G-4S+IN: 4 x SFP+ cages, dual DC barrel-jack ports for redundant power, 1 x 1G copper ethernet port for OOB management. https://mikrotik.com/product/crs305_1g_4s_in
CRS310-1G-5S-4S+OUT: 4 x SFP+ cages, 5 x SFP cages, 1 x 1G copper ethernet port for OOB management, can be mounted outdoors. https://mikrotik.com/product/netfiber_9

MSRP on all three are at or below $249.00 so are priced quite reasonably. If you only need SFP+ cages I'd opt for the CRS305-1G-4S+IN.

Regards,
Christopher Hawker

I'm evaluating CPEs for one of my clients, a regional ISP. Currently, we're terminating the customer's service (L3) on our upstream equipment and extending it over our own fiber to the customer's premise, where it lands in a Juniper EX2200 or EX2300.

At a previous job, I used Accedian's ANTs on the customer prem side. I like the ANT because it has a small footprint with only 2 ports, it's passively cooled, it's very simple to operate, it's controlled centrally, etc. Unfortunately, when I reached out to Accedian, they insisted that the controller (which is required) started at $30k, which is a non-starter for us.

I'm not aware of any other products like this. Does anyone have a recommendation for a simple L2* device to deploy to customer premises? Not necessarily the exact same thing, but something similarly-featured would be ideal.

*I'm not sure if the ANT is exactly "layer 2", but I don't know what else to call it.
