Changing Hardware Settings

If you have a new TDM/Flex or MCMP/Flex or if you
ordered a Flex field installation upgrade for a DSU having
firmware version 6.3x or greater, you do not change
hardware straps; you set each port to operate
independently of the others via the DCP, an async
terminal, or an NMS.
If you ordered the 6-port TDM/Flex or MCMP/Flex
field installation upgrade for a DSU having a firmware
version less than 6.3x, use the S1 switch to change the
TDM or MCMP port interface operation – EIA-232 or
V.35.
If you have a TDM/DSD or MCMP/DSD, use the
option card to change the TDM or MCMP port interface
operation – EIA-232 or V.35.
Follow this procedure to open the DSU and separate it
from the TDM or MCMP (refer to Figures 2-3 and 2-4).
