BECS has been designed from the ground up on an open and well documented API. This to ensure that integration towards existing OSS/BSS system will be as smooth as possible.
BECS abstracts the network northbound, presenting a service catalogue to the BSS. This means that adding new services and new vendors into the network does not require changes in the OSS/BSS. This greatly lowers OPEX over time as the network evolves, considering that OSS/BSS often cost up to 8 times more than the hardware to maintain. Introducing a new service or a new vendor now takes hours or days instead of months.
