1 RAB Example Parallel CS + PS and associated SRB This document details 2 simultaneous RABs and associated SRBs from TS32.8 The RABs are:. Conversational symmetrical Circuit Switched 64 kbps 2. Interactive or Background asymmetric Packet Switched 28 kbps DL, 64 kbps UL The SRB is symmetrical at 3.4 kbps
