NetworkInterface.T1E1[x].Impedance

Specifies the type of cable connecting a CG 6100C board to the telephone network.

Syntax

NetworkInterface.T1E1[x].Impedance = cable_type

x = 0..15 (0-based trunk number or range of trunk numbers)

Access

Read/Write

Type

String

Default

G703_120_OHM

Allowed values

DSX1 | G703_120_OHM

Example

NetworkInterface.T1E1[0..3].Impedance = G703_120_OHM

Details

Valid settings are:

Setting	Description
DSX1 (T1 only)	For DSX1 cables (up to 655 feet - short haul).
G703_120_OHM (E1 only)	For G.703-standard 120 Ohm cables.

Note: If you are connecting a CG 6100C board to a 75 Ohm E1 trunk, run the board at 120 Ohm. The 20-port balun (NMS P/N 33050) performs the signal conversion (from 120 Ohm to 75 Ohm).

Refer to Configuring the T1 or E1 interface for more information.
