Table A-1. In-Band Addressable Loopback Codes (Continued)
Note: All codes listed above must be sent for a minimum of 5 seconds in order for them to be detected and acted upon.
* If NIU is enabled, then the H2TU-R can be in network loopback when the H2TU-C loop up codes are sent.
1
The H2TU-C and H2TU-R individually detect and act upon in-band loopback control codes. Depending on which list number of H2TU-R is used with
the Litespan H2TU-C, some of these control codes may not cause action (such as loop up, error injection, etc.) at the H2TU-R. Refer to the H2TU-R
documentation for supported control codes.
2
Units must be armed with 11000b or FF48h before this code will work.
3
In order to behave like a NIU, the H2TU-R will not loop down from the network side with 9393h.
4
This code will be detected only if the units are armed
OR if any
loopbacks are active.
