Extended Loop Range
This field appears only for a DID trunk group and is used only with the TN459A
circuit pack. Enter y or n depending on the distance between the central office and
the switch. If greater than the required distance, then the field should be y.
Trunk Gain
This field specifies the amplification applied to the trunks in this group. With the
values of the Trunk Termination and Country fields, the value in this field also
determines the input and trans-hybrid balance impedance for TN465B, TN2146,
TN2147, and TN2184 ports. All other CO and DID circuit packs are set
automatically to high
Drop Treatment
This field only applies to DID trunks. It determines what the calling party hears
when the called party terminates an incoming call.
NOTE:
In Italy, the Drop Treatment field must be administered as intercept for all
DID trunk groups.
