HFCL's CDMA equipment is designed according to the protocols and specifications issued by 3GPP2, and implements BSC and PCF functions of the cdma2000 1X system.

The generic network structure of the HFCL's cdma2000 1X system includes:

• Base Station Controller (BSC) Required for control and management, call connection and disconnection, mobility management, providing stable and reliable radio link for the upper-layer services via soft/hard handoff, power control, and radio resource management
  
  
• Packet Control Function (PCF) The PCF mainly implements the R-P connection management. Because of the shortage of radio resources, some radio channels should be released when subscribers do not send or receive data, but the PPP connection is maintained continuously. The PCF can shield radio mobility for the upper-layer services via handoff
  
  
• Base Transceiver Station (BTS) The BTS mainly transmits and receives radio signals, thus the communication between the radio system and mobile stations can be implemented.
  
  
• Mobile Switching Center (MSC) The MSC implements the service switching between the calling and called subscribers. One MSC is connected with multiple BSCs. The MSC can also be connected to the PSTN, ISDN or other MSCs. It provides the interface between the radio network and the public switched network.
  
  
• Inter working Function (IWF) IWF performs switching of circuit data service for mobile subscribers. IWF provided a translation of the user traffic on a data call between the fixed network and the air interface
  
  
• Packet Data Service Node (PDSN) The PDSN implements the switching of the packet data services of mobile subscribers. It provides the interface between the radio network and the packet data network

• Excellent compatibility to legacy standards and scalability
• Reliable platform
• Compact Modular design
• Robust power control management
• Designed keeping in view the future evolution
