This read-write integer sets, in seconds, how often the Clarent Gatekeeper checks its connection to the Command Center, defaulting to 10 seconds with an allowed range of 5 to 120. A shorter interval detects a lost Command Center connection more quickly, while a longer one reduces the associated keepalive overhead. For example, an admin might raise gkCCCKeepAliveTimer toward 120 on a low-bandwidth link to reduce keepalive chatter while still detecting outright disconnection.
