3. When the calls start re-alerting, a timer starts. The timer is set to the value
assigned in the Alerting (sec) field on the Console-Parameters screen.
4. If the attendant does not answer the calls before the timer expires, calls
route to the system Night Service destination. Calls that are not answered at
the night service destination before the night-service-disconnect timer
expires are dropped.
Interactions
■ Attendant Lockout
Attendant Lockout is temporarily disabled on calls that re-alert the
attendant console following a misoperation. This allows an attendant to
answer the calls.
■ Bridged Appearances
Misoperation Alerting calls do not re-alert on bridged call appearances.
■ Voice Response Integration
Do not use Misoperations Handling with this feature if you are using
analog boards with Conversant.
Modem pooling
(Not available with Offer B) Modem Pooling allows switched connections
between digital-data endpoints (data modules) and analog-data endpoints via pods
of acoustic-coupled modems. The analog-data endpoint is either a trunk or a line
circuit.
Detailed description
Data transmission between a digital data endpoint and an analog endpoint requires
conversion via a modem, because the DCP format used by the data module is not
compatible with the modulated signals of an analog modem. A modem translates
DCP format into modulated signals and vice versa.
Modem Pooling feature provides pools of integrated-conversion modems and
combined-conversion modems.
Integrated-conversion modem pools have functionality integrated on the Pooled
Modem circuit pack, providing two modems. Each one emulates a time-division
multiplexing (TDM) cabled to a 212 modem. Integrated are modem pools not
available in countries that use A-law companding.
