STEP 5
Remove all communications devices from the Simulator and press the
DOWNLOAD button. An automatic RESTART is issued as part of the
DOWNLOAD.
Note: This setting is not available when EKTS is disabled. While the Simula-
tor recognizes the CONFerence and TRANSfer call control messages, it does
not perform these services at this time. The ILS-1000 returns a reject mes-
sage, as if the service was not subscribed.
Additional Call Offering (ACO)
The ISDN-BRI equivalent to Call Waiting is
Additional Call Offering or ACO. Termi-
nals that support ACO must be able to perform two functions: first, they must have
the ability to generate tones, rather than rely on tones sent on a B Channel from the
switch. Second, they must be able to recognize B Channel selection during the
connection phase of a call, rather than the setup phase.
If the terminal supports these features, then the switch notifies the terminal of every
call, even when both B Channels are busy (a condition referred to as interface
busy). The terminal may then start its own alerting tone and, if it supports CACH
operation, indicate the call visually.
If the user or a prioritizing system chooses to release a B Channel either by hanging
up or putting a call on hold, the terminal can accept the new incoming call by issuing
a CONNect message. The switch determines which B Channel was released and
assigns it to the new call in a CONNect ACKnowledge message.
If your communications device does not support ACO or if you want to test the
operation of a device during call blocking, disable this setting.
