Solution
There are two places where PVDM4 DSPs are installed. For TDM services, the DSP is installed on the T1/E1 NIM. Since the NIMs support online insertion and removal (OIR) they can be removed without powering down the ISR 4000 Series device, and the DSPs on the NIM can be removed. However, the router must be shut down in order to insert or remove a PVDM4 on the motherboard. Follow this schematic representation in order to install the PVDM4 on NIM.
