Card A

Displays the current condition of the network. Possible conditions are listed in the following chart:

Condition

Description

 

 

Normal

The MX2800 STS-1is ready to pass data.

 

 

Alarm

The unit is currently receiving an alarm indication.

 

Alarm types are discussed in the following

 

section, Card A/Card B Alarms.

 

 

In Test

The unit is currently in test mode. See Chapter 6,

 

Diagnostics for information on the test type.

 

 

Card A/Card B Alarms

This field displays the current alarm condition of the

MX2800 STS-1.Possible conditions are given in the following chart:

Condition

Description

 

 

Normal

No alarms are currently being received.

 

 

LOS

(Loss of Signal)

 

The controller card has lost the network receive

 

signal.

 

 

LOF

(Loss of Framing)

 

The controller card detects a framing loss from the

 

network.

 

 

LOP

(Loss of Pointer)

 

The controller card is unable to detect a valid

 

pointer in the receive signal.

Description

 

 

LOMF

(Loss of Multiframe)

 

The controller card detects loss of H4 multiframe

 

from the network.

 

 

AIS-L

(Line Alarm Indication Signal)

 

The controller card is receiving a line alarm

 

indication signal. The Section Terminating

 

Equipment generates AIS-Lafter detecting LOS

 

or LOF.

 

 

AIS-P

(Path Alarm Indication Signal)

 

The controller card is receiving a path alarm

 

indication signal. AIS-Pis defined as all ones in

 

bytes H1, H2, and H3 as well as all ones in the

 

entire STS synchronous payload envelope.

 

 

RFI-L

(Line Remote Failure Indication)

 

The controller card is receiving a line remote

 

failure indication. RFI-Lis declared when the

 

incoming line remote defect indication (RDI-L,

 

“110” pattern in bits 6, 7, and 8 of the K2 line

 

overhead byte) lasts for 2.5 +/- 0.5 seconds.

 

 

RFI-P

(Path Remote Failure Indication)

 

The controller card is receivinga path remote

 

failure indication. RFI-Pis declared when the

 

incoming path remote defect indication (RDI-P,“1”

 

in bit 5 of the G1 path overhead byte for

 

contiguous frames) lasts for 2.5 +/- 0.5 seconds.

 

 

SLM-P

(Path Signal Lavel Mismatch)

 

The controller card is detecting a signal label

 

mismatch. A received signal label is mismatched

 

if it does not equal the locally provisioned value or

 

the value “equipped non-specific”.

 

 

UEQ-P

(Path Unequipped)

 

The controller card detects that the path is

 

unequipped. The path is unequipped if it is not

 

provisioned. Byte C2 of the STS path overhead is

 

set to zero.

(see XCV Threshold on page 3-12).

 

 

TLOS

(Transmit Loss of Signal)

 

The contoller card’s transmitter has failed.
