description: The Slot Length 2 (sl2) is a parameter within the RACH-ConfigGeneric information element, which specifies the random-access parameters for both regular random access and beam failure recovery in the context of Radio Resource Control (RRC) protocol. It defines one of the possible values for the ra-ResponseWindow field, indicating the length of the response window for random access procedures.
explanation: sl2 is classified as a Parameter because it represents a specific configuration option within the RACH-ConfigGeneric information element, used to customize the behavior of the random access procedure in the 5G New Radio (NR) system. It is part of the protocol specification defined by 3GPP TS 38.331.
