However, a simpler method uses the
Call Appearance Information Element. With
this technique, the switch manages outgoing Call Appearance numbers and assigns
incoming Call Appearance numbers.
The Simulator manages a maximum of 15 Call Appearances per terminal, which is
the default setting. To change the Call Appearance Call Handling setting,
STEP 1
Run the Windows based configuration software.
STEP 2
Select the Call Appearances setting.
STEP 3
Select the number of Call Appearances (00-15).
STEP 4
Select SAVE to save the setting.
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.
Note:
A maximum of 4 calls may be on hold with one connected.
When one or more Call Appearances are enabled, the Calling Party Information
Element is not included in incoming SETUP messages. This means Basic Mode
(AT&T Custom) terminals must have Call Appearances set to 00 to operate
correctly.
Key Hold
Electronic Key Telephone Service (EKTS) terminals may support Hold, Drop,
Transfer, and Conference (HDTC) features. These feature apply to terminals that
manage multiple voice calls. Some of these operations are performed by the Simu-
lator.
When a call is placed on hold, the B Channel allocated to that call is released, but
not the call’s status variables or other switch resources. This means the B Channel
may be used for another purpose, and the original call can be quickly reconnected
after the B Channel is released from its temporary task. Call hold does not apply to
the D Channel.
The Simulator supports both Auto Hold and Auto Drop treatment. This refers to the
action performed on an active call when a different call is selected. With auto hold,
when one call is active and a different call is selected, the first call is placed on hold.
With auto drop, the first call is disconnected.
If your communications device does not support these services, then the Simulator’s
HDTC setting may be disabled.
STEP 1
Run the Windows based configuration software.
STEP 2
Select the KEY HOLD setting.
STEP 3
Select DROP to enable HDTC services with auto drop treatment.
Select HOLD to enable HDTC services with auto hold treatment.
Select OFF to disable HDTC services.
