Managing Data Calls
Data Call Setup
Telephone dialing
To make a data call, an ISDN-BRI phone user presses the data button on the terminal, enters the number
on the dial pad, and then presses the data button again.
The following data functions are not available on ISDN-BRI phones:
•
One-Button Transfer to Data
•
Return-to-Voice
•
Data Call Preindication
•
Voice-Call Transfer to Data and Data-Call Transfer to Voice
The system handles all presently defined BRI bearer data-call requests. Some capabilities that are not
supported by Avaya terminals are provided by non-Avaya terminals. If Communication Manager does not
support a capability, a proper cause value returns to the terminal.
BRI terminals receive a cause or reason code that identifies why a call is being cleared. The BRI data
module converts certain cause values to text messages for display.
In a passive-bus multipoint configuration, the system supports two BRI endpoints per port, thus doubling
the capacity of the BRI circuit pack. When you change the configuration of a BRI from point-to-point to
multipoint, the original endpoint does not need to reinitialize. Only endpoints that support service profile
identifier (SPID) initialization can be administered in a multipoint configuration.
Analog modems
When a telephone user places a data call with a modem, the user dials the data-origination access code
assigned in the system before dialing the endpoint.
Considerations
•
A BRI phone cannot call a data terminal, and a data terminal cannot call a BRI phone.
Interactions
•
Abbreviated Dialing
Only 22 of the 24 (maximum) digits in an abbreviated-dialing number are available for keyboard
dialing. The remaining two digits must contain the wait indicator for tone detection.
•
Call Coverage
A hunt group made up of data endpoints cannot be assigned a coverage path.
•
Call Detail Recording
CDR records the use of modem pools on trunk calls.
•
Call Forwarding All Calls
Calls received by a data module can be forwarded. Activate Call Forwarding All Calls with
data-terminal (keyboard) dialing. If the forwarded-to endpoint is an analog endpoint and the caller
is a digital endpoint, modem pooling is activated automatically.
