Application 139
Other applications
The operating range and built-in protection provisions of the NT1R20 OPS
analog line card make it suitable for applications which are variants on the
traditional configuration shown in Figure 24 "Traditional OPS application
configuration" (page 138). Examples of such applications are:
•
a PBX in a central building serving stations in other buildings in
the vicinity, such as in an industrial park, often called a campus
environment. Facilities can be provided by the local exchange carrier
or can be privately owned. Protection could be required.
•
termination to other than a telephone, such as to a fax machine or a
key telephone system.
• individual circuits on the NT1R20 OPS analog line card can also be
configured as On-Premise Station (ONS) ports in LD 10:
—
ONS service with hazardous and surge voltage protection (not
available on other analog line cards)
— to use otherwise idle NT1R20 OPS analog line card ports
