Page 113: Tributary
MX2800 STS-1 User Manual Loopbacks, Section 6 VT/Port Loopbacks Tributary A Tributary loopback loops the selected VT/Port back to the network (STS-1). The T1/E1 is looped back through the STS-1 mapper. During this loopback, the corresponding DSX-1/E1 input is overwritten by the outgoing DSX-1/E1 signal.
Page 114: Digital Line/Net
Section 6, Loopbacks MX2800 STS-1 User Manual VT/Port Loopbacks Digital Line/Net A Digital Line/Net loopback (Figure 6-5) performs a loopback of the selected T1/E1 in both the network and local loop directions. Both loopbacks occur at the T1/E1 LIU. The network side loopback occurs deep into the LIU through the receiver, receive equalizer, transmit jitter attenuator, and finally, through the T1/E1 transmit drivers.
Page 115: Csu Loopback
Selecting any other option will result in an error message. CSU Loopback w/BERT A CSU Loopback w/BERT enables the MX2800 STS-1 to test the local T1 loop to the CSU using the standard QRSS pseudo-random bit sequence. When CSU Loopback w/BERT is selected, the MX2800 STS-1 will initiate a CSU loopback pattern toward the CSU attached to the selected T1 line similar to the CSU Loopback test above.
Page 116: Vt Bert
A VT BERT test (Figure 6-8) enables the MX2800 STS-1 to perform a “head-to-head” BERT test toward the STS-1 network. The VT BERT test replaces all incoming T1/E1 traffic for the T1/E1 mapped to the selected VT with an unframed QRSS pattern toward the network. When VT BERT is selected, additional menu items display to show the state of pattern synchronization, cumulative error count, and a clear error count option.
Page 117: Line Bert
A Line BERT (Figure 6-9) enables the MX2800 STS-1 to perform a “head-to-head” BERT test toward the T1/E1 line mapped to the VT selected. Selecting Line BERT will replace all outgoing T1/E1 traffic for the T1/E1 mapped to the selected VT with an unframed QRSS pattern. When Line BERT is selected, additional menu items will appear to show the state of pattern synchronization, cumulative error count, and a clear error count option.
Page 118: Loopbacks
Section 6, Loopbacks MX2800 STS-1 User Manual STS-1 Loopbacks STS-1 LOOPBACKS An STS-1 loopback option provides a series of tests on the STS-1 path. The STS-1 Loopback option, from the Loopback menu, displays the screen illustrated in Figure 6-10. The sections following the figure provide descriptions and diagrams of the testing options.
Page 119: Line Loopback
NOTE If a Line Loopback is active when the MX2800 STS-1 is operating in the Free-Run timing mode, the timing source for the STS-1 is effectively removed from the circuit. Therefore, it is up to the test equipment or network to provide STS-1 timing into the circuit for the duration of the test.
Page 120: Digital Loopback
Section 6, Loopbacks MX2800 STS-1 User Manual STS-1 Loopbacks Digital Loopback A Digital Loopback (Figure 6-13) loops the entire STS-1 back to the local loop side. This tests all VT/Ports after passing through the STS-1 mapper and partially through the LIU. The incoming STS-1 data is ignored and the outgoing STS-1 stream is substituted in its place just prior to entering the STS-1 encoder block of the LIU.

Page 122: Non-Redundant Mode
Non-Redundant Mode NON-REDUNDANT MODE In Non-Redundant Mode, the MX2800 STS-1 chassis houses only one controller card, and only one network connection is available. Protection in the event of network failure is not provided. In the event of a failure, an alarm is initiated and condition is indicated by the front panel LEDs.
Page 123: Circuit Failure Recovery Mode
7-2), two controller cards are installed for a single STS-1 line. In this mode, the MX2800 STS-1 can continue operating in the event of a controller card failure. When both cards are fully functional, the primary card actively processes data while the secondary card remains in standby.
Page 124: Circuit And Network Failure Recovery Mode
For example, in Figure 7-3, failed NET A is connected to healthy Card A; and healthy NET B is connected to failed Card B. In such an instance, the MX2800 STS-1 automatically re-routes NET B to Card A. NOTE...

8-2), two power supply cards are installed and connected to a single power source. In this mode, the MX2800 STS-1 can continue to operate during a power supply failure without service interruption. The power supplies are load sharing, so either power supply can provide power for the entire unit.
Page 127: Power Supply And Source Recovery Mode
MX2800 STS-1 handles any combination of a single power source failure or single power supply failure. Much like the backup design for the controller cards, the MX2800 STS-1 is capable of internally re-routing the power source if a power supply card and the opposite power source fail. For example, in the illustration...

With the installation of the ADTRAN Power Supply/Battery Charger (PS/BC) and backup battery pack, the MX2800 STS-1 can continue operation without service interruption during a power outage. This PS/BC (P/N 4175043Lx) provides –48 VDC to the MX2800 STS-1. It receives 115 VAC through a standard plug and wall socket. See Figure 8-4.
