3.From the Loopback screen, press twice to display the RLB selection on the screen.

Loopback:

4. Press F3 to select RLB.

Loopback:

PLB DLB RLB

F1 F2 F3

Test Started appears on Line 2. If a Repeater loopback is already in progress, the Already Active message appears. If an invalid combination of loopbacks is in progress, the error message Invld Test Combo appears (see Table4-8 for valid loopback test combinations).

Starting a Data Channel Loopback

The Data Channel Loopback command (DCLB) loops the data received from the network interface, for all DS0 channels allocated to the selected port, back to the network. The loopback occurs after the data passes through the port circuitry but before it is sent out the data port.

To perform a Data Channel loopback,

1.Press F2 to select Test from the top-level menu screen.

2. From the Test screen, press F2 to select Lpbk.

Test:

Rlpbk Lpbk Ptrns

F1 F2 F3

3.From the Loopback screen, press three times to display the DCLB selection on the screen.

Loopback:

Abort LLB PLB

F1 F2 F3

4. Press F3 to select DCLB.

Loopback:
DLB	RLB	DCLB
F1	F2	F3

5.From the DCLB screen, press the Function key for the port for which you want to perform the data channel loopback. Use the scroll keys, if necessary.

Loopback: DCLB

Prt1	Prt2	Prt3
F1	F2	F3

Test Started appears on Line 2. If a Data Channel loopback is already in progress, the Already Active message appears. If an invalid combination of loopbacks is in progress, the error message Invld Test Combo appears (see Table 4-8 for valid loopback test combinations).
