Using Loopback Tests

189

■

Local Loopback

 — An internal (within the framer) diagnostic 

loopback in which the signal returned towards the source is framed.

■

Framer Loopback

 — An internal (within the framer) loopback that 

tests the path up to where framing is introduced.

■

Payload Loopback

 — A loopback in which the signal returned 

toward the source of the loopback command comprises the payload 
of the received signal (with bit sequence integrity retained) and newly 
generated ESF framing (not necessarily maintaining the integrity of the 
channel timeslots, frames, or superframes of the received signal). The 
newly generated ESF data link contains a valid performance report 
message with a value of one in every LB-labeled bit position for the 
duration of the loopback indicating the signal is the result of a payload 
loopback.

Enabling or Disabling

Loopback Tests

You can use the NBX NetSet utility to enable or disable loopback test 
support for 3C10116D T1 and 3C10165D E1 cards. By default, loopback 
test support is disabled. After you enable loopback test support, you can 
initiate the Local and Framer tests. The Central Office, or test equipment 
emulating Central Office equipment, must initiate Line and Payload tests.

CAUTION: 

If you enable one or more loopback tests, you will terminate 

any active calls on all channels of the selected span and make that span 
unavailable for calls until you disable loopback testing. 

To enable or disable loopback support:

1

Login to the NBX NetSet utility using the administrator login ID and 
password.

2

Click the appropriate link:

■

PSTN Gateway Configuration > T1 Spans

■

PSTN Gateway Configuration > ISDN PRI Spans 

3

Click the MAC address of a span.

4

Enable or disable the Enable Loopbacks check boxes as required and then 
click 

Apply

.

To view the results of Local and Framer loopback testing Span status
