ITU-T RECOMMENDATION SUMMARY




Rec. No. : M.1380

Title : Bringing-into-service of international leased circuits that are
	supported by international data transmission systems

Date of adoption : 04/97




This Recommendation is only applicable to international leased circuits 
that are supported by an international data transmission system.

The requirements described in this Recommendation should ensure that an 
international leased circuit meets performance expectations and is fully 
tested prior to introduction into service.

The bringing-into-service tests described in this Recommendation should 
ideally include periods of normal industrial activity to be representative 
of typical network conditions. 

This Recommendation has been developed to be consistent with Recommendation 
M.1370 [10] that describes the bringing-into-service of international data 
transmission systems. 

Recommendation M.1385 [11] covers maintenance issues for international leased 
circuits that are supported by an international data transmission system.

This Recommendation addresses the bringing-into-service requirements of leased 
circuits with a digital presentation at renters' premises. For circuits with 
an analogue presentation, the bringing-into-service procedures given in 
Recommendation M.1050 [7] apply, with performance achievement in accordance 
with Recommendations M.1020 [3], M.1025 [4] or M.1040 [5] as appropriate.
