FCC Radio Frequency Interference Statement
iMcV-T1/E1/J1
Repeater
Operation Manual
This equipment has been tested and found to comply with the limits for a Class A computing device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which the user will be required to correct the interference at his own expense.
Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
The use of non-shielded I/O cables may not guarantee compliance with FCC RFI limits. This digital apparatus does not exceed the Class A
limits for radio noise emission from digital apparatus set out in the Radio Interference Regulation of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de classe A
prescrites dans le Règlement sur le brouillage radioélectrique publié par le ministère des Communications du Canada.

About the iMcV-T1/E1/J1 Repeater
The iMcV-T1/E1/J1 Repeater chassis mounted media conversion module allows the
end user to extend the distances between T1, J1, and E1 copper telephony systems
by adding a fiber segment. The distances can support up to 100km depending on the
module used and the fiber type available.
Each iMcV-T1/E1/J1 Repeater includes one RJ-48 connector and one pair of SC or ST
fiber optic connectors, which can support any fiber type in MultiMode or
SingleMode. The Repeater series is also available in Single Strand Fiber, with SC
connectors.
Installating an iMcV-T1/E1/J1 Repeater
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 the configuration requirements
change.
Crossover/Straight-Through Connection
iMcV-T1/E1/J1 Repeater comes with an RJ-48 UTP connector that features a push-
button switch, located next to the port, for selecting a crossover 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 is needed, set the push button to the position that turns the NO
LNK LED off.
The iMcV-T1/E1/J1 Repeater Host and Remote modules cannot be both installed in
managed chassis. The recommendation, if using a managed chassis, is to install the
Host in the managed chassis; the Remote Unit should be installed in an unmanaged
chassis.
NOTE
Before installing the modules, they must be configured for Host/Remote via the DIP
Switches. The Master/Slave condition requires this configuration:
S3-2: ON Remote Unit Enabled (only at the REMOTE end)
S3-2: OFF Remote Unit Disabled (only at the LOCAL end)

Managed Modules
To manage iMcV-T1/E1/J1 Repeater modules, an SNMP agent must be present; the
iMediaChassis requires an SNMP management module. For a managed environment,
first manually configure all of the desired DIP Switch selectable features to match
what will be configured through the SNMP Management Module.
NOTE
Before installing the modules, they must be configured for Host/Remote via the DIP
Switches. The Master/Slave condition requires this configuration:
S1-10: ON Remote Unit Enabled (only at the REMOTE end) (Remote)
S1-10: OFF Remote Unit Disabled (only at the LOCAL end) (Host)
Use the Graphical User Interface (GUI) to enable features by using the iView
2
SNMP
management software. In a managed chassis, the software settings take priority over
the SNMP enabled feature DIP Switch settings. Make sure that the software settings
match the desired configuration requirements for the installation.
iView² Management Software
iView² is the B&B Electronics management software designed specifically for the B&B
Electronics “iMcV” family of modules. It features a
GUI
and gives network managers
the ability to monitor and control the manageable B&B Electronics products.
iView² is available in several versions, including WebServer version 3.0, and can also
function as a snap-in module for HP OpenView Network Node Manager and other
third party SNMP Management software.
iView
2
supports the following platforms:
Windows 2000
Windows XP
Windows Vista
Windows 7
The iView
2
management software can be used to change some of the iMcV-T1/E1/J1
Repeater features after installing the modules in the chassis. Refer to the iView
2
online help for more information.
Passive Mode
It is recommended that the default Passive mode configuration is used 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.
Requirements
Before installing the iMcV-T1/E1/J1 Repeater modules, perform the following:
Make sure the modules are correct for the fiber type and distance requirements.
Make sure that T1 UTP lines
DO NOT
use simplex power (no wet lines).
Before installing the iMcV-T1/E1/J1 Repeater modules, verify the DIP Switches
are configured for the feature wanted.
Make sure to deploy the iMcV-T1/E1/J1 Repeater modules in pairs, as
Host/Remote.
Make sure the Remote Chassis is not managed.
Please see the
SNMP
Management Module installation guide for software
configuration options.

Managed Modules
Before installing the iMcV-T1/E1/J1 Repeater module into an unmanaged chassis,
configure the modules for Host/Remote Units. For further information concerning the

The copper line driver for T1 applications can be adjusted to provide standard pre-
distortion (LBO) of the transmitted signal for DSX1 connections. The transmitted
signal level can also be reduced (-7.5dB to -22.5dB) when connecting directly to a
CSU that has limited input range.
For E1 circuits, the transmitter can be configured for either 75 ohm or 120 ohm drive
with normal or high (21db) return loss.
NOTE
The receive termination resistance should match this setting.

Description of DIP Switch-Selectable Options
The iMcV-T1/E1/J1 Repeater module includes DIP Switches for hardware settings for
the optional features. Some of these switch options are overridden by the SNMP
configuration of a managed chassis (refer to the
DIP Switch Table
section for a list of
the iView
2
managed switches).
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)
The copper line receiver sensitivity can be adjusted with this setting. This can be
used to extend the service distance beyond the normal line length.
T1 Lines
E1 Lines
Can extend the effective received signal level from -30dB to -36dB
Can extend the effective received signal level from -12dB to -43dB
Receive LIU Termination (Line Termination)
This option allows the user 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 the user 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 PRBS (2
15
-1 for E1 and 2
20
-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 the user 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.
The addition of this gain can extend the service distance of these lines to 2K feet.
