Though a IP Transceiver can connect up to 10 beltpacks at a time, it uses only ONE audio stream in each direction from the E-IPA card to the IP Transceiver. Each stream is using a single unicast IP address with TWO AES67 channels.

It doesn’t matter if you have 1 beltpack or 10 beltpacks connected and talking, the bandwidth is a constant 7 Mbps each direction.

Additional information can be had by reviewing the IP Transceiver documentation.

<no. of IPTS> * 7 Mbps = total IPT bandwidth
