Diagnostics
Test Loops
• E1 main link local analog loopback, towards the local
DTE
• E1 main link local digital loopback, towards the local
DTE
• E1 main link remote analog loopback, towards the
remote DTE
• Channel loopback, towards the remote DTE
• Channel loopback, towards the local DTE
• E1 sublink remote digital loopback, towards the
remote DTE
• E1 sublink local analog loopback, towards the local
DTE
• E1 sublink remote analog loopback, towards the
remote DTE
• BER test for each data port individually
• Inband code-activated loopback per data port
Note
No loopback can be activated for the Ethernet interfaces.
Statistics
• Per ITU-T Rec. G.706 when CRC-4 is enabled
• OOS and BPV statistics without CRC-4
