For additional information on loopbacks, refer toLoopbacks, Table 7-1.Table 6-3. Test Status MessagesTest Status Message MeaningCSU Loopback Active A CSU Loopback toward the network is currently active. Onlyapplies to a test initiated by the user via the ATI or the NMS.DSU Loopback Active A DSU Loopback toward the network is currently active. Onlyapplies to a test initiated by the user via the ATI or the NMS.Lamp Test Active The Lamp Test is active, causing the LEDs on the front panel tolight.Local Loopback Active A local loopback toward the DTE is currently active.Monitoring 511 onNetworkDSU is monitoring a 511 test pattern on the network interface.Monitoring 511 on Port DSU is monitoring a 511 test pattern on the DTE port.Net-initiated CSU LBActiveA CSU Loopback initiated by the network is currently active. If the network service is 56 kbps, the network loopback isnon-latching. A non-latching loopback ends when thenetwork activation codes stop. If the network service is 64 kbps CC, the network loopbackis latching.Net-initiated DSU LBActiveA DSU Loopback initiated by the network is currently active. If the network service is 56 kbps, the network loopback isnon-latching. A non-latching loopback ends when thenetwork activation codes stop. If the network service is 64 kbps CC, the network loopbackis latching. This condition can only occur when the NetworkInterface option Network-initiated DSU Loopback (64K CC)is enabled. Refer to Network Interface Options, Table A-2.No Test Active Status message, indicating no local, remote, or network test inprogress.Sending 511 onNetworkA 511 test pattern is being sent over the network interface.Sending 511 on Port A 511 test pattern is being sent over the DTE port.V.54-initiated DSU LBActiveA DSU loopback is active that was initiated by the detection ofa V.54 sequence originated by the remote unit. This conditioncan only occur when V.54 Initiated DSU Loopback is enabled.Refer to Network Interface Options, Table A-2.
