Diagnostics

Menu

A sample of the

Diagnostics Menu

is shown below in Figure 5-1.

In this example the word

PULSES

appears on both the equipment

(left hand) and network (right hand) sides of the display. When the

words

PULSES

appears alone, that interface has no alarms.

Figure 5-1 Diagnostics Menu

Since a T1 circuit operates by sending pulses to represent a logical

one, the indication

PULSES

means that the T1 IDCSU portion of this

SCC 2130 in the example above does see pulses on the network

(right side) interface. Therefore, of all the messages which might

appear on this menu in upper case characters,

PULSES

is the only

one which does not represent an alarm condition. Pulses are the

logical opposite of a Loss Of Signal (LOS) condition.

Figure 5-2 below shows the result of disconnecting the T1 circuit

from an SCC 2130 module. The word

PULSES

no longer appears on

the right hand side where network status is indicated. Instead, a

number of alarm conditions are reported including

ALARM

,

FRAME

LOSS

,

CRC ERRORS

and

SIGNAL LOSS

.

NOTE:

Whenever an IDCSU reports Signal Loss, it will report other

alarms as well. The other alarms are caused by the signal

loss condition. Ignore the other alarms and find the cause of

the Signal Loss to restore the T1 to service.
