Transmission considerations
The transmission performance of OPS lines depends on the following
factors:
•
•
•
These factors must be considered when planning applications using the
NT1R20 OPS analog line card. They are important when considering
configurations other than the traditional OPS application as shown in
Figure 25 "Traditional OPS application configuration" (page
following provides basic transmission planning guidelines for various OPS

applications.

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

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.
