MMM-4230 CONFIGURATION INFORMATION 

 
 

Program 4230mmm.tdf

 LK6A 

Installed 

 
LK1  IN 

When using Switch 1 position A ‘Variable Bandwidth’, if the frequency of an input that has an 
assignment of 26.8Mb/s falls below 13.4Mb/s then the assignment will revert to 13.4Mb/s. All other 
conditions mentioned in the Variable Bandwidth section still apply. 

 

OUT  The frequency resetting mentioned above does not occur. 

 
LK2  IN 

Existing Reed Solomon encoding on ASI streams will pass through system. 

 

 

If no RS is present on the input then RS encoding is added.  

 

OUT  Reed Solomon encoding added to input ASI steams regardless of whether existing RS encoding exists 

or not. 

 
LK3 Not 

used. 

 
LK4

*

  IN 

Output G.703 signal will be “framed”. 

OUT  Output G.703 signal will be “unframed”. 

 
LK5

*

  IN 

Output “unshaped” (recommended for output drive lengths > 68m (225ft)). 

 

OUT  Output “shaped” (recommended for output drive lengths < 68m (225ft)). 

 
LK7 

Installing this link will terminate the RS-422 data line. 

 
Note:  * 

Not applicable for 34 Mb/s (E3) version. 

 

MMX-4230 CONFIGURATION INFORMATION 

 
LK1  IN 

Allows instantaneous changes in channel bandwidth allocation as required by the “Variable” Data 
Assignment. 

 

OUT  Error concealment is applied to the packet distribution. 

 
LK2  IN 

Output packet size is always 204 byte and will contain Reed Solomon code regardless of 
corresponding MMM-4230 input packet size. 

 

OUT  Output packet size matches that of corresponding MMM-4230 input packet size. 

 
LK3  IN 

Outputs can be individually disabled by SNMP remote control. Note that this requires SNMP 
functionality within IRT’s SNMP frame. 

 

OUT  All outputs are always enabled. SNMP functionality not required. 

 
LK4

*

  IN 

For input G.703 signal that is “framed”. 

OUT  For input G.703 signal that is not “framed”. 

 
LK5  IN 

Input G.703 equaliser not enabled. 

 

OUT  Input G.703 equaliser enabled. 

 
LK10 

Installing this link will terminate the RS-422 data line. 

 
Note:  * 

Not applicable for 34 Mb/s (E3) version.
