CDSC's demat services are extended through its agents called Depository Participants (DP). Investors are linked to the depository through the DPs. A DP processes all the instructions given by the investors. All the accounts and records of the investor are maintained by CDSC. A DP remains as the point of contact for the investors for carrying out their depository services. CDSC’s system is a centralized database architecture with connectivity to each DP through a secured VPN network. CDSC -DPs can also set up branches with direct electronic connectivity with CDSC. CDSC -DPs can also extend service to investors through their various service centers connected through their back office application Dpsecure.
