What is acTrunkStatusChannels?

This octet string encodes per-channel status for up to 16 channels, where each nibble represents one channel's state: invalid (1), none (2), open (3), media (4), SS7 (5), HDLC (6), DPNSS (7), or CAS (8). Engineers use this to see which channels carry which protocol. A value of 0x44 means channels 0 and 1 both carry media.
