Equipment and Functionality models
The licensing system distinguishes between equipment models and functionality models.
• The following models are assigned as equipment:
eCAP, eESPA, eIO, eLOCATION, eSMS, and eSNMP.
• The following models are assigned as functionality:
eWATCHDOG, eBACKUP, eCONFIG, eDMSAPI, eASYNC, eCSTA, eWEB, eSMTP,
eSMTP_server, eAPI, and eVBVoice.
A key difference between equipment and functionality models is the count of available licenses,
as illustrated in
Table 15: License examples on page 193. Equipment models have only a
specified number of available licenses, while functionality models have an unlimited number
of available licenses.
Table 15: License examples
Module total licenses used free
ECAP [equipment] 3 2 1
EESPA [equipment] 2 2 0
ECSTA [functionality] unlimited N/A N/A
DMSAPI [functionality] unlimited N/A N/A
Whenever a client connects to the eKERNEL through a configuration request, the eKERNEL
determines whether the client is an equipment or functionality model.
• Equipment model
If the client is defined as equipment, the eKERNEL tries to bind this equipment to the
license. Success depends on the availability of a free license. To verify how many licenses
are available on the system, use the Avaya License Manager. This program gives an
overview of bound licenses. If an equipment model disconnects, its license is unbound
and the total of free equipment licenses is increased. On the other hand, if an equipment
module connects, the total of free equipment licenses is decreased (and the total of used
equipment licenses increased). A bound equipment model receives a valid configuration
reply. If the equipment model cannot be bound, a status message is sent as follows:
<pgmsts>NO LICENCE AVAILABLE</pgmsts>.
• Functionality model
If a client is a functionality model, the eKERNEL checks if the given functionality is
available in the license system, and if so, sends a valid configuration reply. If the requested
functionality is not available in the license, a status message is sent as follows:
<pgmsts>NO LICENCE AVAILABLE</pgmsts>.
When a client (equipment or functionality model) is licensed, eKERNEL also provides a
configuration reply, and the specific eKERNEL tab-page is updated with a clear key icon. If the
