European Telecommunications Standards Institute (ETSI) BRI functionality
is provided without terminal portability. The ISDN ETSI BRI services
require the following feature packages:
Description
Integrated Services Digital Network (ISDN) is provided through the remote
cluster controller offshore #2 (RCO2) module. The RCO2 module is part of
the Remote Switching Center Synchronous Optical Network (SONET) or
RSC-S. An RCO2 provides increased ISDN performance capacity.
The packages required for the RSC-S without ISDN are also necessary for
the RSC-S with ISDN. The non-ISDN packages provide several base
functionalities like intraswitching and emergency stand-alone (ESA). The
RSC-S with ISDN builds on these functionalities.
