5.0OPERATION

Once the NetLink-T1ª is installed and configured properly it is ready to place into operation. This section describes the function of the LED indicators, and the use of the loopback and pattern test modes.

5.1 LED DESCRIPTIONS

The NetLink-T1ª is equipped with six LED indicators that monitor the status of communication. Figure 12 (below) shows the location of the LEDs on the NetLink-T1ª Series front panel.

T1 Link

Solid green indicates that the end to end TI

 

link is up. Signifying that the link is active.

 

The TI link LED is off when the link is down

TD

When the unit sends a one, the TD LED is

 

green. When it sends a zero, the TD LED is

 

orange. Moreover, the TD LED is active

 

only in active DS0 channels. In inactive

 

channels, the TD LED is off.

RD

When the unit receives a one, the RD LED

 

is green. When it receives a zero, the RD

 

LED is orange. Moreover, the RD LED is

 

active only in active DS0 channels. In inac-

 

tive channels, the RD LED is off.

ALM

The alarm LED indicates the presence of a

 

Blue or Yellow Alarm, or Out of Frame con-

 

dition. The ALM LED will blink on every half-

 

second. Alarms may occur due to:

 

Loss of Synchronization

 

¥ Loss of Frame

 

¥ AIS (Blue Alarm)

 

¥ RAI (Yellow Alarm)

 

33

ER

The error LED indicates various error condi-

 

tions, including framing bit errors, excessive

 

zeros, controlled slips, severe errors, or bit

 

errors (when sending V.52 test patterns).

 

When sending a test pattern, the LED will

 

remain lit if the unit does not receive the

 

identical pattern. When it receives the cor-

 

rect pattern, the LED will turn off. If error

 

insertion is on, the LED will blink once a

 

second if everything is operating properly.

TM

The test indicator LED blinks with a specific

 

pattern depending on the type of test mode.

 

When the unit is in local analog loop, the

 

LED will blink on briefly. When the unit is in

 

remote loop, the TM LED will blink off

 

briefly. When the unit is sending a test pat-

 

tern or is putting the remote unit into

 

V.54/CSU loopback, the TM LED will stay

 

on. These are the test modes:

 

¥ V.54/CSU Loopback & V.52 Patterns

 

¥ D4 Line Loop (CO initiated)

 

¥ ESF Line Loop (CO Initiated)

 

¥ ESF Payload Loop (CO Initiated)
