The GDPUX processes voice services and data services.
The GDPUX inherits all the functions of the GDPUC. It performs the following functions:
Provides format conversion for 3740 IP speech paths and HDLC optimized speech paths as well as data forwarding
The GDPUX in the GMPS/GEPS performs the function mentioned above in any of the following configuration modes: BM/TC combined, A over IP and Abis over IP, or A over IP and Abis over HDLC.
Encodes and decodes the signals transmitted over a maximum of 960 speech paths
The GDPUX in the GMPS/GEPS performs the function mentioned above in any of the following configuration modes: BM/TC combined, or A over IP and Abis over TDM. The GDPUX in the GTCS performs the function mentioned above in the BM/TC separated configuration mode.
Provides Tandem Free Operation (TFO) function
When the calling and called MSs use one voice coding scheme, the voice signals are encoded only once at the originating MS and decoded only once at the terminating MS. This reduces repeated encoding and decoding and improves the quality of speech services.
Provides voice enhancement function
Detects voice faults automatically
