‘
Serial groups
’
submenu
In the serial group each new call occupies first free port thereby realizing the ‘multichannel phone’ mode.
In ‘multichannel phone’ mode, a call occupies one port. When all the ports are busy, new call will be put in
queue if queue has free ports (otherwise call will be broken up). When port will be free, the first port of queue
will be sent to this free port. Thus, maximum number of calls, which can be sent to the serial group, is
determined by sum of port number in the group and by size of call queue. Throughout its existence, each
individual call is transmitted only to the one port which it occupied initially. It is the main difference from call
group where the first received call occupies all the ports (call is transmitted to these ports in accordance with
selected group type) and the next call is put in free place of queue (if queue does not have free place, the call is
broken up). At that, maximum number of incoming calls are determined as ‘size of queue + 1’.
