Just wondering-on some smartjacks in my area, the tags say something like '90HGS xxxxxx' where the x's are numbers. Is the 90HGS a type of circuit, or is it just some type of ID for the line?

Th first 2 digits city/state codes the next 4 are USOC circuit type codes the last part is a database number that the LEC uses and reuses when they assign circuits. When you call in trouble or repair they use the last number to search for the account and then use the USOC code to determine what type of service it is and the city/state code to send the trouble to the correct repair center. You can tell how old a circuit is by how low the database number is.

so if it was 90XHGS999999, the 90XHGS would be the city and usoc, and the 6 digits would be the database number?

The first 2 numbers in a circuit number are usually part of the LATA (local access and transport area) I am in Verizon area in LATA 246 and all Special Circuits start with 46XXXX. The next 4 characters after the LATA number are USOC code for the type of circuit. If the code starts with X this designates that it is a digital circuit. The last 6 numbers are the actual circuit number in the database of the local exchange or interexchange carrier.
