Support of Interworking with DCME

Summary: The UMG8900 can be connected to the digital circuit multiplication equipment (DCME)

supporting the Q.50 protocol.

Description:The UMG8900 can be connected to the DCME supporting the Q.50 protocol.

The DCME can save the transmission trunk through voice data compression and digital speech interpolation. The Q.50 protocol stipulates the following:

Dependency:  This feature is applied when the UMG8900 interworks with the DCME that complies with the

Q.50 protocol.

This feature is applicable to the VMSC, GMSC, and TMSC

Carriers can flexibly deploy the DCME to reduce the cost of transmission.

Positive thinking in the TX point of view.

• The CN informs the DCME whether a current service is a data service or speech service.
• The CN instructs the DCME whether a service should be compressed. Data services are not compressed.

• The DCME informs the CN when the service load is full. Then, the CN will not assign new services

  
  

  
  

  All the feature described upon are regularly required for analysis purpose.
