3-108 Datafilling ESA lines and trunks on RSC-S International
ESA lines and trunks
ESA, the RSC-S always routes the first party on a multiparty line. The hunts
start with the first party. The system can encounter a corrupt emergency
service trunk. When this condition occurs, hunts continue until the system
exhausts the list or locates a good trunk. The E911 tandem can be a DMS,
1AESS, or 5ESS.
The RSC-S ESA lines feature package is available for RSC-S applications
that support lines. To allow ESA for the RSC-S, the RCO2 must contain
software that provides ESA. Tables required to implement the ESA lines
feature package include tables RCCINV, ESAPXLA and CUSTHEAD. The
ESA office parameters for lines control entry to and exit from ESA. The
ESA office parameters for lines control downloads of ESA static data.
Table RCCINV
Table remote cluster controller inventory (RCCINV) contains inventory
data, except RCO2 P-side link assignments. Table RCCINV requires the
following datafill for ESA application.
The ESA flag in field ESA allows operating company personnel to turn the
ESA option ON or OFF. A change in the ESA flag appears at the DMS CC.
The change indication transfers to the RCO2 during the next update of the
static data. The RCO2 must be Busy (BSY) return the RC02 to service
(RTS) after you change the status of the ESA flag.
When the flag changes, a warning appears at the MAP screen. This warning
indicates the need for an update of the RCO2 static data or ESA static data.
A change to the flag marks the RCO2 in-service trouble (ISTb) with
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 SWACT the RCO2.
Table ESAPXLA
Table emergency stand-alone prefix translation (ESAPXLA) contains special
prefix translation data. Plain ordinary telephone service (POTS) and
297-8331-815 Standard 10.01 August 1999

You must enter field TRMTYPE in table RCCINV with entry
ESALINES.
You must enter field EXEC in table RCCINV with entry ESAEX.
Field ESA in table RCCINV is Boolean and must be set to Y when the
RSC-S has the ESA option.
