RIC-E1Installation and Operation Manual

 

 

To activate the local analog loopback from the standalone RIC-E1:

1.Open the RIC-E1 case, as described in Chapter 2.

2.Set the JP11 jumper to LOC.

The analog loopback is activated and the TST indicator on the front panel turns on.

To activate the local analog loopback from RIC-E1/R:

Press the ANA pushbutton on the RIC-E1/R front panel.

Make sure that the PNL SW jumper (JP5) on the RIC-E1/R board is set to EN.

The TST indicator on the front panel turns on.

Deactivating Local Analog Loopback

To deactivate the local analog loopback from the DTE:

Lower the circuit 141 pins of the DTE interface.

To deactivate the local analog loopback from the standalone RIC-E1:

Set the RIC-E1 JP11 jumper to DTE.

The TST indicator on the front panel turns off.

To deactivate the local analog loopback from the standalone RIC-E1/R:

Press the RIC-E1/R ANA pushbutton again to return it to the previous position.

Trouble Symptoms

Probable Cause

Corrective Measures

 

 

 

 

 

 

 

 

All front panel indicators

1.

No power

Check that both ends of the power cable

 

are OFF

 

 

 

are properly connected.

 

 

 

 

 

 

 

 

 

 

2.

Blown fuse

Disconnect power cable from both ends

 

 

 

 

 

and replace the fuse with another fuse of

 

 

 

 

 

proper rating.

 

 

 

 

 

 

 

LOS indicator is ON

1.

Receive line fuses are blown

Disconnect power cable from both ends

 

 

 

 

 

and replace the fuses with new fuses of

 

 

 

 

 

proper rating.

 

 

 

 

 

 

 

 

 

 

2.

Line cables are not properly

Check and adjust both ends of the line

 

 

 

 

connected

cables.

 

 

 

 

 

 

 

 

 

 

3.

Unbalanced BNC connectors

Switch the two BNC connectors.

 

 

 

 

are reversed

 

 

 

 

 

 

 

 

 

 

 

 

4.

The transformer is damaged

Replace RIC-E1.
