If not, change the setting of your KX-T336 and CSU.
Then check the clock mode.
Check the cabling between "T-1/E-1 and CSU" and "CSU
and NIU." If not properly cabled, change the cabling.
Execute Loopback Test(Internal).
Replace the T-1/E-1
card with a new one.
Execute Loopback Test(External: between KX-T336 and
CSU)
Check the CSU. If not good, replace it with a new one.
Ask the T-1/E-1 carrier to check the line conditions.
Or, check the equipment in other switching system which
your T-1/E-1 lines are connected with.
Another T-1/E-1 card with next priority will work as a master card, if more
than two T-1/E-1 cards were registered to the system by CLP command
(Refer to Section 64.03) beforehand. Otherwise, the system will synchronize
with the system internal clock. Note
