Figure 6-6. Codec Loopback
Remote Loopback
A Remote Loopback performs a loopback of the selected T1/E1 on the far-end M13 multi-
plexer. If an MX2800 is located at the far end, an Analog Network Loopback is executed when
a Remote Loopback
is engaged. This loopback is only available when the DS3 is configured for
C-bit parity framing since it requires the availability of the far-end alarm and control (FEAC)
channel. See ANSI T1.107.
CSU Loopback
A CSU Loopback enables the MX2800 to generate a CSU loop up pattern (001001…) toward
the T1 CSU attached to the selected T1 line for six seconds. After six seconds have elapsed,
the pattern ceases; and incoming network traffic is passed through to the CSU device. If the
CSU device responded to the CSU loop up pattern, it returns all data back toward the
network. A loop down pattern (0000100001….) is generated toward the CSU for 6 seconds
when Data Mode is selected.
NOTE
When in
CSU Loopback, only the Data Mode for the T1 under test may
be selected. Selecting any other option will result in an error mes-
sage.
CSU Loopback w/BERT
A CSU Loopback w/BERT enables the MX2800 to test the local T1 loop to the CSU using the
QRSS pseudorandom bit sequence. When
CSU Loopback w/BERT is selected, the MX2800
initiates a CSU loopback toward the CSU attached to the selected T1 line. Six seconds after
starting the CSU loop up pattern, the MX2800 ceases sending the CSU loop up pattern and
begins sending an unframed QRSS pattern toward the CSU. If the CSU device responded to
the CSU loop up pattern, the MX2800 checks the incoming pattern for errors. Additional
menu items appear to show the state of pattern synchronization, error count, and a clear error
count option. See Figure 6-7. Selecting Data Mode will cease the transmission of the QRSS
pattern and start transmission of a loop down pattern as previously described.
