Prerequisites
Before you install the iMcV-T1/E1/J1 modules, perform the following:
•
Make sure you have the correct modules for your fiber type and your distance
requirements.
•
•
Make sure that T1 UTP lines DO NOT use simplex power (no wet lines).
Before you install the iMcV-T1/E1/J1 modules you must verify the DIP switches
are configured for the feature wanted.
•
•
Make sure you deploy the iMcV-T1/E1/J1 modules in pairs.
Make sure the Remote Chassis is not managed.
NOTE
The iMcV-T1/E1/J1 modules are delivered pre-configured for standard T1

You can use the iView2 management software to change some of the
iMcV-T1/E1/J1 features after installing the modules in the chassis. Refer to the iView2
online help for more information.
Passive Mode
It is recommended that you use the default Passive mode configuration for most
typical applications. Passive mode allows the fiber segment to pass data unchanged
between the T1/E1 segments independent of the actual line coding (AMI, B8ZS, or
HDB3). All errors and fault conditions from one T1/E1 end will pass through the fiber
to the other end as if there were one long T1/E1 connection.

MediaChassis
The MediaChassis provides a typical unmanaged chassis suitable for all remote
installation locations.
NOTE
Chassis may also be available in Industrial Ethernet (IE) configurations.
Each module requires one slot in the chassis. To install a module, remove the blank
brackets covering the slots where the module is to be installed (if present) by
removing the screws on the outside edges of the bracket. Slide the module into the
chassis, via the card guides, until the module is seated securely in the connector.
Secure the module to the chassis by tightening the captive screw. Save any “blanks”
removed during installation for future use should your configuration requirements
change.
Crossover/Straight-Through Connection
iMcV-T1/E1/J1 comes with an RJ48 UTP connector that features a push-button
switch, located next to the port, for selecting a crossover workstation or straight-
through connection. To select a cross-over connection, press the push-button IN. A
straight-through connection is selected when the push-button is OUT. When unsure
what type of connection you need, set the push button to the position that turns the
NO LNK LED off.

Unmanaged Modules
Before installing the iMcV-T1/E1/J1 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 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
iView2 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 you to selects 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 you 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 you 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 you 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.
11
Download from Www.Somanuals.com. All Manuals Search And Download.
Receive LIU Termination (Line Termination)
This option allows you to set the receive termination. This is used to properly
terminate cables in order to prevent signal reflections which can cause signal
degradation.
Transmit Data Source
This option allows you to set the module to send normal data (default) or to send
specific test-patterns of data to determine problems along the cable as a diagnostic
tool. The user can set the module to send a pseudorandom bit sequence (PRBS)
(215-1 for E1 and 220-1 for T1), an alternating ones and zeros, or an unframed all ones
code, depending on the diagnostic requirements.
Jitter Attenuator Select
This option allows you to select Jitter Attenuation on the UTP transmit or receive side.
This decreases jitter in the data stream which increases data reliability.
NOTE
The jitter attenuator must always be enabled on the transmit side of the copper
line.
Loopback Selection
This option allows you to set the Loopback location on the module. Loopback is a
diagnostic tool that enables the user to test the integrity of the line by allowing the
data to be looped back. The following independent loopback locations are included
on the module:
•
•
•
Analog Loopback - Set this switch on the Remote module to loop the data back
from the remote copper port (refer to the Remote Copper Loopback Mode
section for more information).
Local Loopback – Set this switch on the Remote module to loop the data back
from the remote fiber port (refer to the Remote Fiber Loopback Mode section for
more information).
Remote Loopback - Set this switch on the local module to loop the data back
from the local fiber port (refer to the Local Fiber Loopback Mode section for
more information).
Refer to the Loopback Testing section for application examples of the loopback testing
modes.

Remote Management
This option allows you to enable Remote management on the module. The remote
management feature is designed to work only on the remote module of the
Local/Remote pair. With Remote management enabled, you can easily perform the
following:
•
•
•
Test the line integrity of the remote copper port.
Use the Local unit to configure all SNMP-configurable features for both units.
Use the Local unit to download firmware for both units.
Refer to the Module LED Functions section for more information.
NOTE
When you enable the Remote management feature on the remote module, you
must disable SNMP-management on the chassis in which the remote unit is
installed (i.e. turn the iMediaCenter chassis SNMP switch off, or do not install an
SNMP Management module in either an iMediaChassis or iMcV series chassis.
Monitor/Boost Mode
This option allows you to boost the UTP receive signal (i.e internal linear gain boost).
This helps the UTP receiver to compensate for line loss.
NRZ (Non-Return-to-Zero)
This option allows you to enable or disable the NRZ mode.
NOTE
There are currently no applications that use any other settings than AMI encoding
and NRZ disabled (Passive mode). Enabling NRZ can result in data corruption.
Enabling NRZ terminates the line coding on the copper line. This forces the module
to send raw data to the fiber line without line code information.

Testing
To test a media converter by itself, first make sure you have an appropriate fiber
patch cable, then perform the following steps:
1. Connect the media converter to the T1/E1 device with a standard UTP cable. If
the NO LNK LED for the copper port remains on, you are not receiving a valid
signal. Push the crossover push button on the front of the unit. Verify that the
NO LNK LED for the copper port is off.
2. Loop a single strand of fiber from the transmit port to the receive port of the
media converter. Verify that the NO LNK LED for the fiber port is off.
Or
For single-strand fiber products, connect a single fiber cable from the Local
iMcV-T1/E1/J1 to the remote iMcV-T1/E1/J1. Verify that the NO LNK LED for
the fiber port is off.
Loopback Testing
The iMcV-T1/E1/J1 includes the following loopback locations:
•
•
•
Local
Remote
Analog.
Local Loopback
The Local loopback location on the module
loops the fiber-receive port to the fiber-transmit
port.
Remote Loopback
The Remote loopback location on the module
loops the fiber-transmit port to the fiber-
receive port.
Analog Loopback
The Analog loopback location on the module
loops the copper-transmit port to the copper-
receive port.

The iMcV-T1/E1/J1 can be configured to use the following loopback test modes:
•
•
•
Local Fiber Loopback Mode
This setting tests the path from the CO copper port to the Local iMcV-T1/E1/J1
module fiber port and back.
Remote Fiber Loopback Mode
This setting tests the path from the CO copper port to the Remote iMcV-T1/E1/J1
module fiber port and loops it back.
Remote Copper Loopback Mode
This setting tests the path from the CO copper port to the Remote iMcV-T1/E1/J1
module copper port and loops it back.
The following illustrations show a typical progression of digital loopback tests; this
series allows you to individually test each segment of the conversion. To test the
copper segment at the remote location requires the PRBS test described in the next
section.
Local Fiber Loopback Mode
To set the loopback testing mode to Local Fiber Loopback Mode, perform the
following:
1. Set the Local iMcV-T1/E1/J1 module to Remote Loopback
(DIP switch S3-3=Off and S3-4=Off)
2. Set the Remote iMcV-T1/E1/J1 module Loopback to None
(DIP switch S3-3=On and S3-4=On).
This configuration allows you to test the path from the CO copper port to the Local
iMcV-T1/E1/J1 module fiber port and loop it back. The transmitted data is sent
unhindered and the received data is ignored.

Remote Fiber Loopback Mode
To set the loopback testing mode to Remote Fiber Loopback Mode, perform the
following:
1. Set the Local iMcV-T1/E1/J1 module Loopback to None
(DIP switch S3-3=On and S3-4=On)
2. Set the Remote iMcV-T1/E1/J1 module to Local Loopback
(DIP switch S3-3=Off and S3-4=On).
This configuration allows you to test the path from the CO copper port to the Remote
iMcV-T1/E1/J1 module fiber port and loop it back. The transmitted data is sent
unhindered and the received data is ignored.
Remote Copper Loopback Mode
To set the loopback testing mode to Remote Copper Loopback Mode, perform the
following:
1. Set the Local iMcV-T1/E1/J1 module Loopback to None
(DIP switch S3-3=On and S3-4=On)
2. Set the Remote iMcV-T1/E1/J1 module to Analog Loopback
(DIP switch S3-3=On and S3-4=Off).
This configuration allows you to test the path from the CO copper port to the Remote
iMcV-T1/E1/J1 module copper port and loop it back. The transmitted data is sent
unhindered and the received data is ignored.
After you have confirmed the integrity of these data paths, you can activate the PRBS
data generator on the Remote module and place a loopback on the customer
premise equipment to test the final copper segment (refer to the Testing with
Pseudorandom Bit Sequence (PRBS) section for more information).
