VCL- Mega. Connect - Jr. , T 1 DACS To monitor an T 1 link in a single direction, you will need to connect ONE high impedence T 1, RX pair of the DACS, as it is only the Rx (RECEIVE) pair that is capable of listening. Please leave the Tx (TRANSMIT) pair un-connected. Orion Telecom Networks Inc. - 2006 Slide 7

VCL- Mega. Connect - Jr. , T 1 DACS To monitor an T 1 link in both directions, you will need to connect TWO high impedence T 1, RX pairs of the DACS, i. e. use 1, Hi-Z T 1 ports. A Total of 7 T 1 links can be monitored bi-directionally aggregated to 2 T 1’s. Orion Telecom Networks Inc. - 2006 Slide 8
