NOTE
Protected ONS Lines
Protected ONS ports (ONSP) are available on
ports 1 and 2 on the CXi II Controller with AMB Version III
•
ports 1 and 2 on the MXe Controller (PN 50005090) with AMB Version III.
•
The ONSP ports are suitable for off-premise applications, and meet the requirements of 60950-01 and
IEC 55-24. Regular ONS ports are intended for on-premise applications only.
ONSP ports use the same loss plan settings as regular ONS ports.
