Application 141
The transmission performance of OPS lines depends on the following
factors:
• the Meridian 1 port-to-port loss for connections between OPS ports
and other Meridian 1 ports
• the transmission parameters of the facilities between the Meridian 1
OPS port and the off-premise station or termination
•
the electrical and acoustic transmission characteristics of the
termination
These factors must be considered when planning applications using the
OPS analog line card. They are important if considering configurations
other than the traditional OPS application shown in
Figure 24 "Traditional
OPS application configuration" (page 138) .
The following information provides basic transmission planning guidelines
for various OPS applications.
The transmission performance of OPS lines is dependent on a number of
factors.
•
The Meridian 1 port-to-port loss for connections between OPS ports
and other Meridian 1 ports.
• The transmission parameters of the facilities between the Meridian 1
OPS port and the off-premise station or termination.
• The electrical and acoustic transmission characteristics of the
termination.
These factors must be considered when planning applications using the
OPS analog line card. They are of particular importance when considering
configurations other than the traditional OPS application as shown in
QPC430 and QPC723 interfaces. The discussion which follows is intended
to provide basic transmission planning guidelines for various OPS
applications.
