As per specs, it should be when there are
"no further messages waiting in the queue",
which means ZLB ACK could be sent _as soon as_
it processes SCCCN and discovers there are
no messages waiting to be sent.

Subject: ZLB Ack.

What is the condition to send a ZLB Ack (see the example below), is this a
timer or something else ? The rfc says only that "the ZLB Ack is sent if
there are no futher messages waiting in the queue".

LAC						LNS

SCCRQ ---->
					<----SCCRP
SCCCN ---->
					<----ZLB ACK

But generally after the SCCCN, the LAC sends an ICRQ and the LNS can't send
the ZLB ACK.
Thank you for your help.
