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.
If the TDM1 is chosen, it indicates that the MX100E synchronizes its clock with the opposite
device connected to the first TDM interface.
If the Local is chosen, it indicates that the MX100E synchronizes with the local device.
Framing
If the MX100E DS1 Type is set to T1 then Line Framing can be set to D4, SF (Superframe), ESF
(Extended Superframe) mode.
If the MX100E DS1 Type is set to E1 then Line Framing can be set to E1_MF_CRC mode.
Line code
If the MX100E DS1 Type is set to T1 then Line Code can be set to B8ZS or AMI.
If the MX100E 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.
Table 5-6 Operated Numbers and Translation Rules
Operated Number
The four following types of operated numbers exist:
InCPN: Operates the calling numbers of calls from ISDN.
InCDPN: Operates the called numbers of calls from ISDN.
OutCPN: Operates the calling numbers of calls to ISDN.
OutCDPN: Operates the called numbers of calls to ISDN.
