4.11.4 Configuring the TDM Bus

The procedure below describes how to configure the TDM bus of the Enhanced gateway.

 To configure the TDM bus:

Bus Settings).

2. Configure the TDM bus parameters according to your deployment requirements.

Below is a description of some of the main TDM parameters:

a. PCM Law Select: defines the type of PCM companding law in the input/output

TDM bus. Typically, A-Law is used for E1 and Mu-Law for T1/J1.

b. TDM Bus Clock Source: defines the clock source to which the Enhanced

gateway synchronizes - generate clock from local source (Internal) or recover

clock from PSTN line (Network).

c. TDM Bus Local Reference: defines the physical trunk ID from which the

Enhanced gateway recovers (receives) its clock synchronization when the TDM

Bus Clock Source is configured to recover the clock from the PSTN line.

3. Click Submit to apply your changes.

4. On the toolbar, click Burn to save the settings to the Enhanced gateway flash

memory.

5. Reset the device with a burn to flash for this setting to take effect (see Section 4.16

on page 70).
