10.2.7 APS Tasks

10.2.7.1 APS Timing

This function measures the Automatic Protection Switching (APS) limits of the network. APS applies only to the

Multiplex sections of a SONET network and enables network elements to re-route traffic to a backup circuit in the

event of network failure or problems. The protection mechanism is coordinated by the K1 and K2 bytes in the

Multiplexer Section Overhead.

APS Standards

The principles and protocols of APS in SONET networks are defined in ITU-T G.783 and G.841 and Bellcore

GR-253 recommendations for Linear and Ring network architectures respectively. According to these

recommendations, the re-routing of the signal has to occur within 50ms. Protection switching is initiated as a

result of one of the following conditions:

“Hard” Failure (SF) condition – Loss of Signal (LOS), MS-AIS, BER >1 x 10

-3

“Soft” Failure (SD) condition – Signal degradation when BER exceeds a predetermined threshold.
Normally over a provisioned range of 1 x 10

-5

to 1 x 10

-9

Tap the

APS Testing

icon to display the APS testing screens shown below.

Sensor:

Select the trigger that will initiate the APS measurement.

The selections are: LOS, LOF, SONET FAS, B1, B2, B3, AIS-L, RDI-L, REI-L, AIS-P, LOP-P, RDI-P,

REI-P, AIS-V, 2M-LOF, 2M-AIS, LSS and TSE (bit errors)

Switch Time Limit:

Configurable in the range from 15ms to 200ms.

Typically 50ms according to ITU-T recommendations.

Gate Time

: Configurable in the range from 50ms to 4 seconds.

Used to measure total service disruption when multiple switches or micro interrupts occur.

Repeat

: ON/OFF

Configurable to measure on a continuous basis.

Start

: Press to begin the test.
