Specifies the type of cable connecting a CG 6060 board to the T1 or E1 network.
NetworkInterface.T1E1[x].Impedance = cable_type
x = 0-(n-1) (0-based trunk number or range of trunk numbers where n equals the number of trunks on the board.)

G703_120_OHM
DSX1 | G703_75_OHM | G703_120_OHM | HIGH_IMPEDANCE
NetworkInterface.T1E1[0..3].Impedance = G703_120_OHM
Trunk impedance on the CG 6060 is controlled through a board configuration file. Since trunks are configured in pairs, the configuration setting must be identical for both trunks in a given pair. Trunks are paired as follows:
0 and 2
1 and 3
Valid settings are:
