NT1R20 Off-Premise Station Analog Line card
•
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
OPS application configuration" (page 149)
.
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" (page 472)
. The discussion which
follows is intended to provide basic transmission planning guidelines for
various OPS applications.
The transmission performance of OPS lines depends on the following
factors:
•
the port-to-port loss for connections between OPS ports and other ports
•
the transmission parameters of the facilities between the 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 when considering
configurations other than the traditional OPS application as shown in
91 "NTCK80AA/AB/AC/AD" (page 338)
. The following provides basic
transmission planning guidelines for various OPS applications.
Port-to-port loss
Loss is inserted between OPS analog line card ports and other ports in
accordance with the loss plan. This plan determines the port-to-port loss
for each call.
