DS-1/1C Channel Access Test Set Requirements

Issue Date Jun 1984
ABSTRACT: Many of the transmission interfaces within the Local Exchange Carriers (LECs) and between LECs and other service providers are at the
DS1 (1.544 Mbps) and DS1C (3.152 Mbps) digital line rates. Test equipment that will perform monitoring as well as drop and insert
testing functions is needed to access these lines at the DS0 rate in order to effectively maintain network services that are offered
over these facilities.
This Technical Advisory (TA) describes the preliminary view of Telcordia on generic requirements and features for a DS1/1C Channel
Access Test Set that can be used to determine both the quality of the DS1/1C digital signal and perform Voice Frequency (VF) and
signaling tests on a selected DS0 channel. The principle users of this test set will be maintenance engineers, technical support
personnel and local craft personnel.
