The Receive Equalizer Gain Limit switch controls the similarly named feature of the T1 transceiver. Set the Receive Equalizer Gain Limit switch according to the following table:

Open

-36 dB (long haul)

 

 

Closed

-15 dB (limited long haul)

 

 

The Lamp Test switch turns on all LEDs on the VNA’s front panel. It is used during production of the VNA. The Lamp Test switch will not function when the VNA detects the MCU (MCU FLT LED is Off). Set the Lamp Test switch according to the following table:

Open

All front panel LEDs function normally.

 

 

Close

All front panel LEDs are ON

 

 

The Customer Disconnect function presents a well-behaved signal on the T1 line. This signal is sometimes useful during troubleshooting and verification. Set the Customer Disconnect Enable switch according to the following table:

Open

The T1 transceiver is operating normally.

 

 

Closed

The Customer Disconnect signal is being transmitted on the T1 line. This setting disrupts the

 

T1 signal and the MCU reports a T1 line fault.

 

 

The Local Loop Back feature sometimes is used during troubleshooting. Set the Local Loop Back switch according to the following table:

Open

The T1 transceiver is operating normally.

 

 

Closed

The “Framer Loopback” feature of the T1 transceiver is enabled. The T1 transceiver transmits

 

the Blue Alarm on the T1 transmit line during this condition. This setting disrupts the T1 signal

 

and the MCU reports a T1 line fault. This setting causes the VNA to receive the T1 signal it

 

normally would transmit, while actually transmitting the Blue Alarm.

 

 

The Remote Loop Back feature sometimes is used during troubleshooting. Set the Remote Loop Back switch according to the following table:

Open

The T1 transceiver is operating normally.

 

 

Closed

The “Remote Loopback” feature of the T1 transceiver is enabled. This setting disrupts the T1

 

signal and the MCU reports a T1 line fault. This setting causes the VNA to transmit its received

 

T1 signal. The T1 standards mention two types of loopbacks: “line” and “payload”; this

 

loopback is a “line” loopback.
