• External, from the attached DTE
• Receive, derived from the received signal
Diagnostics
Loopbacks
ITU V.54:
• Local loopback, activated via management software or by
the DTE interface signal (V.35 and RS-530 only)
• Remote loopback, activated via management software or
by the DTE interface signal (V.35 and RS-530 only)
• Remote loopback at SHDSL repeater
Statistics Collection
• E1 with CRC-4 or T1 with ESF framing: per ITU G.706
• E1 without CRC-4 or T1 with SF framing: bipolar
violations (BPV)
• SHDSL performance
