# path ds3 equipment loopback

#### Syntax

path pathChannel ds3 ds3Channel equipment { customer | network } loopback

no path pathChannel ds3 ds3Channel equipment

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Enables or disables the router’s ability to be placed in loopback by a remote device connected at the DS3 layer for a DS3 signal. This command applies to a DS3 over channelized SONET interface. The no version restores the default behavior, which disables the router’s ability to be placed in loopback by a remote device. Using the no version has the same effect as issuing the command with the network keyword.

#### Options

- pathChannel—Number, in the range 1–2147483648, that identifies the path
- ds3Channel—Number, in the range 1–3, that identifies the path
- customer—Enables the router to start loopback testing when it receives an appropriate signal from the remote interface
- network—Disables the router’s ability to start loopback testing when it receives an appropriate signal from the remote interface; this is the default behavior
