Test Access
Use the Test Access subtab to view test access points in CTC. The test access (TACC) feature allows a third-party Broadband Remote Test Unit (BRTU) to create nonintrusive test access points (TAPs) to monitor the circuits on the node for errors. Circuits can be split (intrusive), so that the transmission paths can be tested for bit errors using bit test patterns. The node supports the Hekimian/Spirent BRTU-93 (6750) and the TTC/Acterna Centest 650 BRTUs. For more information about test access, refer to the Cisco ONS SONET TL1 Command Guide.
