This OID stores an integer representing the maximum number of switched virtual circuit (SVC) user calls—dynamically created connections—that can exist simultaneously on this channel. An engineer adjusts this to control resource consumption and prevent call flooding; once the limit is reached, new incoming SVC requests are rejected. Example: setting to 20 means the device will allow up to 20 concurrent dynamic calls; a 21st call request will be denied until an existing call terminates.
