1-10 Physical Description ASMi-52 Ver. 2.8
ASMi-52 includes an internal Bit Error Rate Tester (BERT) for complete testing of
the local and remote modem and the link quality without any need for an
external test equipment. ASMi-52 runs an internal pseudo-random 511-bit test
pattern in accordance with the ITU V.52 standard.
Real time alarms provide information on the system status, indicating
management failure, synchronization loss and other conditions.
Statistics Collection
ASMi-52 supports SHDSL and E1/T1 statistics collection and standard G.826.
Alarm Reporting
ASMi-52 alarms are relayed via a dedicated 6-pin terminal block connector.
SHDSL Repeaters
Up to eight SHDSL repeaters can be installed in line to increase the operation
range of the modem. ASMi-52 provides basic management of the repeaters.
SHDSL repeaters do not support ASMi-52 versions with T1 interface.
