Gateways Series for Aeonix

5.3.4 TDM Configuration

In case of full configurations, the TGWxE1-2G has one 4T1/E1 card, with four interfaces numbering
TDM1 to TDM4 from left to right. It is recommended to set parameters corresponding to the interface
configured. Parameters for each interface are identical. You can set different parameter values for each
interface as needed. For parameter setting, take the TDM1 as an example:
Click the Basic > TDM tab to open the TDM configuration interface.

Description
Determines whether the T1/E1 interface operates as a T1 or E1 interface.
Allows configuring the PCM encoding type. Allowed settings are µLaw and ALaw.
Set the clock synchronization source. It is TDM 1 by default.
If TDM 1/2/3/4 is selected, it indicates that the TGWxE1-2G synchronizes its clock with the

opposite device connected to the first/second/third/fourth TDM interface.
If Local is selected, it indicates that the TGWxE1-2G synchronizes with the local device.

You can adjust the value of this parameter to increase the voice volume received from the ISDN
network and sent to the IP network.
If the TGWxE1-2G DS1 Type is set to T1, Line Framing can be set to D4, SF (Superframe), ESF
(Extended Superframe) mode.
If the TGWxE1-2G DS1 Type is set to E1, Line Framing can be set to E1_MF_CRC mode.
If the TGWxE1-2G DS1 Type is set to T1, Line Code can be set to B8ZS or AMI.
If the TGWxE1-2G DS1 Type is set to E1, Line Code can be set to HDB3.
This parameter is displayed when E1 is selected, with the value of 120 (Ohm).
This parameter is displayed when T1 is selected, with 0 dB and 7.5 dB for long haul and 36.67 m
for short haul.
Its configuration process is complicated. If necessary, please contact our technical support team.
Note: This feature allows to adjust or change the nth digit of the operated number (4 types).
