5-8 ESA maintenance overview
•
Call channel management
The calls at a Star Hub in ESA mode are inter-switched. An inter-switched
channel is required to complete a call.
Digitone receiver management
The ESA software in the RCP card must have the location of DTRs in the
NTTR73AA universal maintenance pack (UMP) card. The system downloads
the DTR data with the static data. Because digitone receivers are allocated in
297-8353-550 Standard 05.01 March 2001
waits for the result of the coin function. Supervision continues on the

call-processing data
— Digit count/digit registers: The registers contain digits the system
collects. Digit count indicates the number of collected digits.
— Routing information: This byte contains the results of digit translation.
The possible results include the following types of termination:
– regular
– automatic line
– revertive
– hunt group
– reorder termination
– busy
— Terminator line character. The byte is the result of the digit translation.
— Terminator ring character. The byte contains the ringing
characteristics as a result of digit translation.
— Originator revertive ring character. The byte contains the ringing
characteristics of digit translation.
— Originator, terminator, DTR. The byte contains the channel numbers
of the three types of terminals that use channels in an active call.
— Translation and audit-specific data. The data that translations use as
flags for audits on a call processing block during the digit collection
phase.
