Firmware upgrade support : HTTP / TFTP protocol.
Scalability:
Up to
100
Mbps symmetric performance over single-pair wiring for VDSL2 Channel
port aggregation.
Interleave delay time: To prevent the transmission against burst errors.
Noise Margins(SNRM): In
electrical engineering
,
noise margin
is the amount by which a
signal
exceeds the minimum
amount for proper operation. MEG821AE default value is 6db for telecom standard.
Upstream Power Back-Off (UPBO): helps to run services over loops with
different
length co-located in the same cable binder (“mixed length” deployments), especially
in FEXT-dominated noise environment.
Strong FEXT generated by short loops can significantly degrade the performance
of long loops if UPBO is not applied. On the other hand, UPBO reduces the transmit
power of short loops and thus degrades their performance as well. The UPBO
technique should take in account both issues.
Downstream Power Back-Off (DPBO):
The development of Triple Play services requires higher bandwidth. Higher
bandwidth and substantial performance gain can be reached by deploying DSLAM-s in a remote side cabinet near to the
customer premises. There is no problem at clean networks where all the customers are connected to the same local cabinet.
