5.0 OPERATION

Once the NetLink-T1™ 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-T1™ is equipped with six LED indicators that monitor the status of communication. Figure 12 (below) shows the location of the LEDs on the NetLink-T1™ Series front panel.

10BaseT T1/FT1 CSU/DSU

 

Figure 7: 2720/I 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

10BT Link

(Active Green) Solid green indicates that

 

the 10BaseT Ethernet interface has detect

 

ed a valid SQE heartbeat, signifying a valid

 

10BaseT connection.

 

Status

Blinks yellow from one to eleven times to

 

indicate system status. Each pulse pattern

 

is separated by a 2 second “off” period.

 

Greater pulse patterns have

higher

 

priority (buffer saturation has greater priority

 

than an empty MAC table). Valid system

 

statuses are:

 

 

1 pulse

=

system status is okay

 

 

2 pulses =

no MAC entries in the

 

 

 

 

MAC Address Table

 

 

3 pulses =

Clear to Send (CTS) or

 

 

 

 

Carrier Detect (DCD) from

 

 

 

 

base unit are not asserted

 

 

4 pulses

=

IM1/I buffer is saturated

 

 

5 pulses

=

WAN receive frame(s) too large

 

6 pulses

=

WAN receive frame(s) not octet

 

 

 

aligned

 

 

7 pulses

=

WAN receive frame(s) aborted

 

8 pulses

=

Detected WAN receive frame(s) with

 

 

 

CRC

 

35

9 pulses = Detected LAN receive frame(s) too

 

large

 

10 pulses = Detected LAN receive frame(s) not

 

octet aligned

 

11 pulses = Detected LAN receive frame(s) with

 

bad CRC

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)

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)
