We are building a new fiber network, and need help creating a circuit ID format to for new fiber circuits. Is there a guide or standard for fiber circuit formats? Does the circuit ID change when say a customer upgrades for 100Mbps to 1Gbps port?
I've seen a few different methods for this, the most common includes some form of the source/dest pop locations for the service delivery. an example: yy-chcgil-dllstx-xx where yy and xx may provide some more detail. the pop codes might include more detail about the equipment in use, same for yy/xx that might encode the underlying service/speeds or numbering in the case of multiple things involved. from the circuit-id you would be able to look up other details like underlying carriers, service or abstraction layers such as what routers/DWDM/fiber the service rides upon.
What do the larger carriers do? Any advice on creating a circuit ID format for a brand new fiber network?
I would stick with some variant of A-Z location data and leave any service speeds at the phy speed of the device, eg: don't call it 300m if it's 1G ethernet rate-limited.
Originally we ran a CLEC using a LECs copper, and our circuit ID was historically a telephone number for DSL circuits. The ILEC had a complex method for assigning circuit IDs.
I've seen a few different types over the years from ISDN to T1 to much faster services. They all have merit, but the key is to be usable and readble. Don't use both 0 and O for example, don't make case sensitive, avoid lookalikes like l and 1. I would even consider putting in a check digit if you are creating your own.
I am sure anything will work as long as you keep track of it, but any advice would be great!
