This read-only Unsigned32, in Kbps and ranging 0 to 65535, indicates the endpoint's bandwidth, typically 64 times the number of channels the endpoint terminates. An admin reads this to verify the actual provisioned bandwidth of a given endpoint matches what's expected for its channel count, useful when auditing capacity across many endpoints. An endpoint showing a speed that isn't a clean multiple of 64 Kbps would prompt an admin to check its channel-map configuration for inconsistency.
