Description Of Dip Switch-Selectable Options - IMC Networks iMcV-T1 Operation Manual

Unmanaged Modules
Before installing the iMcV-T1/E1/J1 Repeater module into an unmanaged chassis,
configure the module hardware-selectable features via DIP Switches located at
position S3 and S2 on the PCB (refer to the DIP Switch Table section for more
information). The jumpers located at positions JP1 and JP2 are factory configured—
DO NOT CHANGE.

Description of DIP Switch-Selectable Options

The iMcV-T1/E1/J1 Repeater module includes movable DIP Switches for hard
switching the optional features. Some of these switch options are overridden by the
management setting of a managed chassis (refer to the DIP Switch Table section for a
2
list of the iView managed switches).
This module is shipped in the standard T1 option configuration. The following
section contains a brief description of the available options.
T1/E1/J1 Mode
This option allows the user to select the data rate standard that the module will use
when converting: T1/J1 (default) or E1. The default is OFF, T1/J1 mode selected.
Receive Equalizer Gain Limit (EGL)
This option allows the user to compensate for diminishing signal intensity over the
data line by adjusting the sensitivity of the UTP receiver. By setting the Receive
Equalizer Gain Limit, very long copper lines can be utilized.
Line Encoding
This option allows the user to set the transmit/receive encoding for HDB3, B8ZS or
AMI (default).
There are currently no applications that use any other settings than AMI encoding and
NRZ disabled (Passive mode). Changing the encoding setting to anything other than AMI
can result in data corruption.
Transmit LIU Waveshape (Line Build-out)
This option allows the user to control the waveshape being output by the transmitter.
This helps to correct problems related to long cables. Improperly setting this switch
will cause signal degradation.
