1. Loopback Mode
In normal operation, all loopbacks are disabled. Loopback settings are used for troubleshooting
purposes. There are four loopback settings as follows:
1. Off (disable all loopbacks)
2. Remote (enable remote loopback)
3. Local (enable local loopback)
4. 2713 Hz (enable 2713Hz induced loopback)
After all settings are made in the “Chan 1 ” window, set the parameters in the “Chan 2” window.
After all VF-5C parameter selections have been made they must be written to the VF-5C card in the
network. This is done by using the “WRITE” operation as described in Section 7 of The IMUX 2000
Instruction Manual.
