This feature can be controlled by SNMP–Management software (iView

) when the 

HOST iMcV-T1/E1/J1-LineTerm module is installed in a managed chassis. 

Fault Loopback 

This switch enables or disables the Fault Loopback feature on the copper port.  A 
normal copper line fault LOS will cause Remote Alarm Indictor (RAI) to be sent on 
to the fiber line segment causing the normal AIS to be sent on the far end copper 
port.  This feature provides for a fault indication to be sent back to the copper line 
as an AIS signal.  In this way, both upstream and downstream personnel are 
alerted to a copper cable fault.  

The Fault Loopback feature is always active on the fiber line.  When a fiber line 
becomes unavailable, the module detects the LOS on the fiber link and lights the 
LOS LED.  The module then sends AIS to the local copper port and sends a RAI 
signal back to the fiber.  The far end unit turns ON the RAI LED and outputs AIS to 
the far end copper line.  With this, a local site administrator can quickly determine 
where a fiber fault is located from either end of the fiber line.   

The AIS is transmitted as an unframed all ones pattern on the copper port. 

The default loopback DIP Switch is disabled by default. 

This feature can be controlled by SNMP-Management software (iView

) when the 

HOST iMcV-T1/E1/J1-LineTerm module is installed in a managed chassis. 

Transmit LIU Waveshape and Gain (Line Build-Out) 

This group of switches can be configured for the length of line the unit is driving, 
from 0 feet to a maximum of 655 feet.  For longer length lines, the unit can be 
configured for CSU signal gain to address -7.5 db, -15db, and -22.5 db degraded 
signals. 

By default this feature is set to 0 to 133 feet line Buildout for DSX1 lines. 

Transmit Data Source 

These switches select the transmit mode used by the iMcV-T1/E1/J1-LineTerm 
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 2

20

-1 PRBS Pattern) 

These standard Telco transmission pattern modes are provided to help diagnose 
transmission errors in the line.
