The CMPT (8E1) does not support transmission over the optical port. The RBS6601 base station consists of a cabinet that houses the different subsystems and components required for radio access. It may include power supplies, control units, and cooling systems to ensure reliable operation. The Ericsson RRUS12 B8 is a compact and scalable base station solution designed for multi-standard radio access networks. It supports various wireless technologies, including GSM, WCDMA, LTE, and LTE Advanced. The RBS6601 base station is part of Ericsson's RBS6000 series, which is widely deployed worldwide. The RRUs, such as the Ericsson KRC 161 262/2 RRUS12 B8, are responsible for transmitting and receiving radio signals to and from user devices. They are connected to the baseband unit through fiber optic or other transport links.
