As far as I have understood Q.921, the TEI check procedure is done to find out which TEs are still online, and which TEIs are no longer in use (because those TEs have left the bus), for the sole purpose of being able to reclaim unused TEIs. Actually, the switch will initiate a check on arrival of a TEI request if the maximum number of TEIs are already assigned, and thus no free TEI is available. Whether this check is addressed to individual TEIs or the group TEI might be implementation specific. Under the assumption that we don't have any TEI, we should not try to get one until we need it.
