This is the CLLI code BCWDOH46DSO, city, state, office. Usually written with an A and Z end, so if it's the same office would be 101/T1ZF/BCWDOH46DSO/BCWDOH46DSO 101 is the carrier the T1ZF is the circuit type. This would be a local carrier. Long haul would be something like 1/T1F/AUSTTXGR/DLLSTXTL. As Dex said this information shouldn't be at the DEMARC has nothing to do with circuit ID's.
