When the UMG8900 and the MGC work together as a GSM gateway exchange, the UMG8900 receives voice service streams from an external network such as the PSTN through the TDM interfaces. The signaling is sent to the MGC through an independent SG or through direct connections to the MGC. The signaling can also be transferred to the MGC through the SG embedded in the UMG8900.

The UMG8900 supports complete SG functions. The UMG8900 can transmit signaling from the core network, SS7 signaling, M2UA signaling, and M3UA signaling.
