Timing
Derived from three alternative sources:
• Internal oscillator
• External, from the attached DTE
• Receive, derived from the received signal
Diagnostics
Loopbacks ITU V.54:
• Local analog loopback, activated via the management
software or by the DTE interface signal (V.35 and
RS-530 only)
• Remote digital loopback, activated via the
management software or by the DTE interface signal
(V.35 and RS-530 only)
• Remote loopback at the SHDSL repeater
BER Test BERT+RLB or BERT from either CO or CPE (not in the
ASMi-52/ETH models)
Performance Monitoring • SHDSL statistics collection
• E1 with CRC-4 or T1 with ESF framing per ITU G.706
