5.3.4 TDM Configuration
In case of full configurations, the TGWXE1 has one 4T1/E1 card, with four interfaces numbering TDM1
to TDM4 from left to right. You are 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 Basic > TDM tab to open the configuration interface.
Figure 5-5 TDM Configuration Interface
Table 5-5 TDM Configuration Parameters
Name Description
DS1 type DS1 Type configures if the T1/E1 interface operates as a T1 or E1 interface.
PCM codec Allows configuring the PCM encoding type. Allowed settings are ULaw and ALaw.
Timing source Set the clock synchronization source. It is TDM1 by default.

If the TDM1/2/3/4 is chosen, it indicates that the TGWXE1 synchronizes its clock with the
opposite device connected to the first/second/third/forth TDM interface.

If the Local is chosen, it indicates that the TGWXE1 synchronizes with the local device.
Gain to IP
You can increase the value of this parameter to increase the voice volume received from ISDN
network and sent to IP network.
Framing
If the TGWXE1 DS1 Type is set to T1 then Line Framing can be set to D4, SF (Superframe),
ESF (Extended Superframe) mode.
If the TGWXE1 DS1 Type is set to E1 then Line Framing can be set to E1_MF_CRC mode.
Line code If the TGWXE1 DS1 Type is set to T1 then Line Code can be set to B8ZS or AMI.
If the TGWXE1 DS1 Type is set to E1 then Line Code can be set to HDB3.
Line impedance The configuration is displayed when E1 is chosen, with the value of 120 OHM.
Line length The configuration is displayed when T1 is chosen, with 0 db and 7.5 db for long haul and 36.67
m for short haul.
Digit adjust Its configuration process is complicated. If necessary, please contact the technical support.
Number
Transformation
Number Transformation on each T1/E1 link.
Rule format for number transformation on a single T1/E1 link:
Operated number: Operation rule set/Operated number: Operation rule set
For details about operated numbers and translation rules, see Table 5-6.
