Country
This field is administered at installation and sets numerous parameters to appropriate values for the
public network in which the server running Communication Manager operates. For example, the value of
this field, with the values of the Trunk Termination and the Trunk Gain fields, determines the input and
trans-hybrid balance impedance requirements for ports on TN465B, TN2146, and TN2147 circuit packs.
This field appears for the trunk groups that connect Avaya Communication Manager to a central office in
the public network — CO, DID, DIOD, FX, and WATS trunk groups.
CAUTION:
Don't change this field. If you have questions, contact your Avaya representative.
NOTE:
For DID trunk types, country code 19 is not accepted in the Trunk Group screen in
Communication Manager. This will be supported at a later date.
