6.6 Frequently Asked Questions

Question: In which cases is it not possible to loop the ASMi-52 modem via the diagnostic screen?

Answer: There are two possible reasons why the loops options do not appear in the diagnostic screen:

1.The modem has an ETH interface, and since there are no loops in ETH, this option does not exist.

2.When two modems are connected back-to-back and one of them is in loop mode, the other modem cannot access the loop options.

Question: What are the different types of SHDSL mapping supported by RAD products?

Answer: There are 3 modes of transferring user data over SHDSL: Serial ATM

Slotted E1 n × 64

Since SHDSL defines its own framing, the data must be "converted" to one of the three framing types defined above. Serial ATM uses ATM features (ATM cells, UVR, VBR, CBR, and so on); while slotted E1 defines timeslots as the timeslots used for E1 Tx (up to 2048 kbps). Finally, n × 64 defines the data rate of the serial port data in steps of 64 kbps, starting from 64 kbps, and ending in 4.6 Mbps.
