Service Resource Module

In addition, the VPU can provide all the functions of the ECU. The corresponding physical boards are the MVPD and MECU.

Does this imply you can achieve the ECU functionality when you only installed the MVPD board ??

VPU(MVPB):

Supporting functions such as announcement playing, digit collecting, audio mixing and Multiple Frequency Control (MFC).

Implementing IP packet adaptation of voice services based on UDP, Real-time Transport Protocol (RTP), and IP. Supporting varied voice codec types including G.711A, G.711μ, G.723, G.726, G.729, AMR, AMR 2 and FR/HR/EFR.

Accepting resource control and management from the CMU.
