Configure loss and level plan

The loss and level plan determines parameters, such as transmission gain, that
vary from country to country.
Dynamic Loss Plan
A Dynamic Loss Plan has been implemented to define the gateway loss value
per endpoint connection type. The loss plan adjusts the Voice Gateway Media
Card gateway channel's loss for each call by sending pad values to the card.
Loss plan values are now configured through LD 73.
Default values
The default values in the system are for the North American loss plan.
Non-North American countries
Installation of IP Line 4.5 in any other country requires setting the pad values
in Table 15 to that country's loss plan. If the system is installed in other
countries, the GPRI package (International 1.5/2.0 Mb/s Gateway
package 167) must be used, and the NTP-specified values must be entered in
LD 73. At the PDCA prompt, enter Table 15.
Refer to Transmission Parameters (553-3001-182) for more information.
United Kingdom
In addition, when a system is installed in the UK, the CLI command
UKLossPlanSet is entered at the CLI of one card in each node. This adjusts
the loss plan of the IP Phones to the higher transmit levels required in the UK.
Follow the steps in Procedure 33 to set the loss plan for the UK.
