ISDN Interfaces
RPTU Interface Unit
The CSU is transparent to data, clock, and framing. It acts as a repeater, not a controller, for
timing. The CSU also acts as a signal regenerator and must be able to perform loop-back tests and
maintenance to both the network and DK RPTU. The CSU is the same type as used for T1 circuits
although it performs the function as NT1 for PRI ISDN in the ISDN reference model as shown in
Figure 16-1.

DK424i, the maximum combined PCBs cannot exceed the numbers provided in
