Instruction 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

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).

NOTE

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.
