This read-only display string packs together several gateway-wide status figures -- the number of ports currently in use plus per-port call counts, call time, and hold time -- into a single '#'-delimited text blob. An admin monitoring overall gateway health can poll this one object to get a quick multi-metric snapshot instead of querying each underlying counter separately. For example, parsing this string might reveal a leading port-in-use count followed by delimited per-port call/time segments, letting a script extract all the figures from one GET.
