Figure 93: Example of an image at the publisher level on page 88 shows a network where
one Publisher and two Subscribers lead to eight images, and depend on each Boolean state
of available (1) or unavailable (0).
The syntax for images on publisher level are similar to P:1:S0:1-S1:1. Each section is
separated by a minus sign (-).
• The P:1 or P:0 denotes the state of the publisher
• The S0:1 or S0:1 denotes the state of first subscriber
• The S1:1 or S1:1 denotes the state of second subscriber

Recommendation
Avaya recommends that you begin with a definition on the Publisher level that refers to the
same environment for each image, and with a definition on the Subscriber level that refers to
the same environment for each image.
In this initial setup no environment changes occur, and initial testing can take place.
In a later stage you can modify environments. A copy of the production environment is usually
made at the Subscriber sites, for example, Site 1 – Environment 10.110.50.140 and Site 1 –
Environment 10.110.50.140 (backup). In this backup environment, the tasks can be altered,
for example, an eKERNEL instance can be added, and eKERNEL_address refers to a local
instance of eKERNEL.
