4.6.5 Defining TDM Bus Settings
The procedure below describes how to define TDM bus settings.
¾
To define the TDM bus settings:
1. Open the 'TDM Bus Settings' page ( Configuration tab > TDM Configuration menu > TDM
Bus Settings ).
Figure 4-24: TDM Bus Settings Page
2. Configure the TDM bus parameters according to your deployment as required.
•
PCM Law Select - determines the type of PCM companding law in input/output TDM
bus. Typically, A-Law is used for E1 spans and Mu-Law for T1/J1 spans.
•
TDM Bus Clock Source – determines the clock source to which the Media Gateway
synchronizes. Generate clock from local source (Internal) or Recover clock from PSTN
line (Network).
•
TDM Bus Local Reference – determine the Physical Trunk ID from which the Media
Gateway recovers (receives) its clock synchronization when the TDM Bus Clock Source
is configured to recover the clock from PSTN line.
3. Click Submit to save your changes.
4. Save (burn) the Media Gateway configuration and reset the Media Gateway, using the Web
interface’s ‘Maintenance Actions’ page (
Management Configuration menu > Maintenance
Actions ).
4.6.6 Uploading CAS Files and Assigning to Trunks
If your deployment supports Channel Associated Signaling (CAS), you need to upload the CAS
configuration file from your PC to the Media Gateway and then assign the CAS file to the trunk
that is connected to the PBX. You can upload up to eight CAS files and assign different files to
different trunks. The CAS file is downloaded from the Web in the same ZIP file as the
ini
configuration file.
The CAS files contain the CAS Protocol definitions for CAS-terminated trunks. The Media
Gateway supports different variants of CAS protocols for E1 and T1 spans, including MFC R2,
E&M immediate start, E&M delay dial/start, loop start, and ground start.
Note: Ensure that the CAS table is applicable for operating with the deployed
PBX/PSTN interfaces.

To upload CAS files and assign to Trunks:
1. Open the 'Load Auxiliary Files' page ( Management tab > Software Update menu > Load
Auxiliary Files ).
