The current RXCDR does not accept packet switched voice. The RXCDR has a dedicated chan- nel between the call processing BSC and the MSC via the RXCDR system to do the voice encoding/ decoding. The current RXCDR does no switching ofthe voice conversation dynamically. No BSC device has sufficient connections to the TDM highway to allow both the input of the 24 DSO(s) as one chan- nel and then the routing ofthe packets to the XCDR board over other TDM connections. Current digital cellular networks (e.g.: USDL, GSM, iDEN) use ded- icated bandwidth for each voice call and there is no mechanism to share bandwidth assigned to a voice call for other calls or services. The dedicated bandwidth is currently allocated at 16kbps while only 4.8kbps is actually used. This is a very inefficient allocation ofsystem resources.
