2-54Operation, administration, and maintenance (OAM) features

Facility attributes

Visible and provisionable facility attributes include the following:

•Signal degrade threshold (SDTH)

•Auto in service (AINS)

•Section trace

•Path trace

•Equalization (DS1)

•Frame Format (DS1)

•Line build out (DS3, EC-1)

•DS1, DS3, and EC-1 loopbacks

All supported facility attributes (except loopbacks) are default provisioned when equipment is provisioned.

Loopbacks

Terminal loopback

A terminal loopback routes an incoming signal towards the backplane. An alarm indication signal (AIS) is generated in the outward direction of the signal.

Facility loopback

During a facility loopback, a signal received on the optical or electrical side of the facility is looped back towards the associated return transmitter An alarm indication signal (AIS) is generated in the onward direction of the signal. To operate a facility loopback, the facility must be manually put out of service (OOS).

Note: The facility must be out-of-service before a loopback is permitted and both types of loopback cannot be active for a given facility at the same time.

Facility loopback implementation complies with the latest issues of:

•GR-253-CORE, Synchronous Optical Network (SONET) Transport Systems: Common Generic Criteria

•GR-819-CORE, Network maintenance: Access and Testing - Special Services (SS) and SS-like networks

Refer to Figure 2-29for details on electrical loopback types.
