Transmit LIU Waveshape (Line Build-Out) 

This switch selects the optimal transmit waveshape for the line build-out distance on 
the coax line.  The transmit waveshape can be set for a distance of either 0 to 255 

feet or over 255 feet.  This feature corrects problems related to cabling (i.e. cross-talk, 

electromagnetic interference, etc.).  Improperly setting this switch will cause signal 

degradation. 
By default this feature is set to 

> 255 FEET

This feature can be controlled by SNMP management software (iView

2

) when the 

iMcV-DS3/E3/STS module is installed in a managed chassis. 

Transmit Data Source 

These switches select the transmit mode used by the iMcV-DS3/E3/STS module.  The 

transmit modes that can be selected include the following: 

 

Standard data 

 

Unframed All Ones (diagnostic) 

 

Alternating Ones and Zeros (diagnostic) 

 

Pseudorandom bit sequence (diagnostic) 

These standard Telco transmission pattern modes are provided to help diagnose 

transmission errors in the line. 
By default this feature is set to 

STANDARD DATA

This feature can be controlled by SNMP management software (iView

2

) when the 

iMcV-DS3/E3/STS module is installed in a managed chassis.

DS3, E3 and STS Selection 

This switch selects the data rate to use on the coax line.  The data rate selections 
available include the following: 

 

45 Mbps (DS3) 

 

34 Mbps (E3) 

 

52 Mbps (STS) 

By default this feature is set to 

45 Mbps (DS3)

This feature can only be selected by setting the DIP Switches manually.
