Protected ONS ports (ONSP) are available on the
4 + 12 Port Combo card (can be used on the ASU II and the AX).

24 port and 16 port ONS card (can be used on the ASU II and the AX).
•
The ONSP ports are suitable for off-premise applications and meet the requirements of 60950-01 and IEC
55024. Regular ONS ports are intended for on-premise applications only.
ONS lines connect to the module using a 25-pair female D-type (Amphenol) connector.
ONSP ports use the same loss plan settings as regular ONS ports. You require a TDM license to enable
each port.
Both the 4 + 12 Port Combo cards and ONS cards are hot-swappable.
LS CLASS
The AX and ASU II support Custom Local Access Signaling Services (CLASS) on the LS trunks and ONS
lines. CLASS allows the 3300 ICP system to pass Calling Line ID digits and CLASS name information to
display sets that support Caller ID functionality. The ASU II also supports ETSI signalling. The signalling
type is set in the System Administration Tool.
