Abstract
An Interchangeable Standard Port or Stack Port (ISPSP) uses a standard physical connector such as an RJ-45 or SFP. The ISPSP automatically detects whether it is connected to a standard port, such as a 1000BaseT, or whether it is connected to another ISPSP stacking port. This automatic detection can be done through hardware or software. Once the auto-detection is complete the routing platform will automatically configure the ISPSP port for standard 1 Gbps bit rate and framing, or for stacking, e.g., 2.5 Gbps bit rate, and framing.
