4-106 Datafilling ESA lines and trunks on RSC-S UK / Europe
ESA lines and trunks
CUSTHEAD. The ESA office parameters for lines control entry to and exit
from ESA control the download of ESA static data.
Table RCCINV
Table remote cluster controller inventory (RCCINV) contains inventory
data, except RCO2 P-side link assignments. The following data entries must
be in table RCCINV for ESA application.
The ESA flag in field ESA allows operating company personnel to turn the
ESA option ON or OFF. The DMS CC immediately reflects a change in the
ESA flag. The system transfers the change indication to the RCO2 when the
next update of the static data occurs. You must busy (BSY) and return to
service (RTS) the RCO2 immediately after the change of status of the ESA
flag.
When you change the flag, a warning appears at the MAP screen. This
warning indicates the need for an update of the RCO2 static data or ESA
static data. The MAP screen indicates that the RCO2 is in-service trouble
(ISTb) and indicates STATIC DATA or ESA STATIC DATA as the reason.
To change the ESA flag, perform the following steps:
1 Change field ESA in table RCCINV to the required setting.
2 Manually busy and return the inactive RCO2 unit to service.
3 Perform a SWACT on the RCO2.
Table ESAPXLA
Table emergency stand-alone prefix translation (ESAPXLA) contains special
prefix translation data. Plain ordinary telephone service (POTS) and
Meridian Digital Centrex (MDC) customer groups use this prefix translation
data. The RCO2 does not use this table in normal operation. Translations
occur in the central control (CC). If loss of communication with the host
occurs, and the RCO2 enters ESA mode, the system uses this table in the
prefix translations.
Table CUSTHEAD
Table customer header (CUSTHEAD) links a customer group to the prefix
translation table name. Table ESAPXLA identifies this name.

(continued)
Field TRMTYPE in table RCCINV must contain data entry ESALINES.
Field EXEC in table RCCINV must contain data entry ESAEX.
Field ESA in table RCCINV is Boolean and must be set to Y if the
RSC-S has the ESA option.
