Esa Translation Data - Nortel DMS-100 Series Maintenance Manual

receivers are allocated in a circular fashion, all receivers receive equal
distribution. The following steps explain how the system uses a receiver.
1. When a line goes off-hook and originates a call, the system requests a
receiver.
2. If the system finds an available receiver, the system marks the available
receiver, not free, and assigns this receiver to the call.
If all receivers are assigned, the system waits 3 s to locate a free receiver.
If the system does not find a free receiver after 3 s, the system places the
line in the abandon state.
3. When dialing finishes, the system marks the receiver, free. The receiver
is available for another call to use.
The system also frees a receiver when the system receives a dial pulse (DP)
digit. The system receives a DP digit when a user uses a DP phone on a line
entered as Digitone. When the system frees the receiver, the system
maximizes DTR use.
ESA CC supervision sender
The ESA CC uses a streamlined set of execs to handle call processing. The
system loads the definition of execs in the ESA exec lineup at the exec
download time of the RTS sequence. The supervision sender uses the execs to
create work requests for the server.

ESA translation data

When the OPM is in ESA mode, the ESA CC uses a subset of translation data
from the DMS CC to perform translations. The DMS CC downloads this
subset of the DMS CC data, needed for ESA call processing, to the ESA CC.
This type of translation data is static data. The system generates ESA logs
when the downloaded data exceeds the OPM ESA maximum. Refer to
Extended Peripheral Modules Translations Reference Manual for more
information about ESA translations.
The ESA CC requires two types of static data:
• general XPM-type
• ESA translations
The general static data are manually downloaded when the ESA CC is ManB.
The system loads general static data when the ESA CC returns to service. The
system loads ESA static translations data when the ESA CC is in service
(InSv).
