Understanding RSC-S International translations
You must understand the RSC-S concepts and terminology before you enter
data in the Remote Switching Center-SONET (RSC-S) product. This
chapter describes the product in general terms as a background to enter data
in the RSC-S.
Differences between RSC and RSC-S
The RSC-S is like the RSC. For example, RSC-S is available with or
without ISDN. The RSC-S requires the same call processing software as a
requirement to install RSC-S. The RSC-S is an improved version of the
RSC. New software functionality, revised system architecture and revised
component packages implement these improvements. Software packages
support international technology for international offices.
Software functionality
Combine standard RSC packages and the RSC-S basic package to obtain
RSC-S software features. The RSC packages provide separate features. The
RSC-S basic package activates these features and provides specified RSC-S
capabilities. The RSC-S improves the basic call processing of the RSC.
The RSC-S provides the following improvements for intraswitching and
emergency stand-alone (ESA) failure contingency services:
• Intraswitching allows calls that originate and terminate on the RSC-S to
switch without the use of host links.
• The ESA continues RSC-S service when a loss of communication with
the host occurs.
• Warm SWACT allows stable calls to continue without interruption when
a controlled or uncontrolled transfer of RSC-S call processing occurs.
An improvement in the pre-SWACT/post-SWACT audit process reduces
the possibility of loss of service. The loss of service occurs when the
mate remote center offshore #2 (RCO2) cannot gain and maintain call
processing activities.
