# NetworkInterface.T1E1[x].Impedance

Specifies the type of cable connecting a CG 6060C board to the network.

#### Syntax

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.)

#### Access

Read/Write

#### Type

String

#### Default

G703_120_OHM

#### Allowed values

DSX1 | G703_75_OHM | G703_120_OHM | HIGH_IMPEDANCE

#### Example

NetworkInterface.T1E1[0..7].Impedance = G703_120_OHM

#### Details

The NetworkInterface.T1E1[x].Impedance setting varies based on the CG 6060C board variant and the network connection. Valid settings are:

Setting | Description
DSX1 (T1 only) | For DSX1 cables (up to 655 feet - short haul).
G703_75_OHM (E1 only) | For G.703-standard 75 ohm cables.
G703_120_OHM (E1 only) | For G.703-standard 120 ohm cables.
HIGH_IMPEDANCE (T1 or E1) | Reserved for T1 or E1 trunk monitoring applications.

For more information, refer to Configuring the T1 or E1 interface.
