iMcV-DS3/E3/STS-LineTerm is an SNMP manageable module that converts standard
thin coax signals ( DS3, E3/STS, STS ) to a single-mode or multi-mode fiber signal. It
performs the standard “LineTermination” (GR-820-CORE) function of these TDM-
based line signals. This function transmits an Alarm Indication Signal (AIS) on the line
whenever a received signal is lost. Line faults can easily be isolated to one line
section and do not propagate over multiple-line sections as they do with normal line
repeaters.
Each module includes one pair of BNC connectors and one pair of ST or SC fiber
optic connectors. This module can be installed in any iMediaChassis or MediaChassis
series, but can only be managed through a SNMP manageable iMediaChassis. DS3
Line Term modules must be configured as Host and Remote. To configure a module
as a Remote, set DIP Switch #10 to ON.
In addition, it is available with single-strand fiber: iMcV-DS3/E3/STS-LineTerm
BNC/SSFX modules allow two wavelengths (1310 nm and 1550 nm) to share one
fiber strand, essentially doubling the capacity of installed fiber. The single-strand
versions as HOST and REMOTE must have opposite transmit and receive wavelengths
iMcV-DS3/E3/STS-LineTerm modules must be deployed in pairs (one at each end of a
fiber line). The data transmitted on the fiber ports can only be received and
interpreted by another iMcV-DS3/E3/STS-LineTerm unit.
Installation
iMcV-DS3/E3/STS-LineTerm modules can be installed in any iMediaChassis or
MediaChassis series, but can be managed only through the iMediaChassis. 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 by removing the
screws on the outside edges of the bracket. Slide the module into the chassis card
guides, until the module is securely seated in the connector. Secure the module to
the chassis by tightening the captive screw. Save any blanks removed during
installation for future use.
NOTE
It is not recommended that the iMcV-DS3/E3/STS-LineTerm module be installed in an IE-
MediaChassis/1-DC chassis (850-33100). The power source in this chassis is not isolated and
cannot support positive referenced ground systems typically used in Telco environments. The
IE-MediaChassis/2-DC and the iMediaChassis/6-DC are suitable alternatives.

Configuration
Proper configuration of the iMcV-DS3/E3/STS-LineTerm is required for maximum
performance and reliability. The following sections describe the prerequisites and the
configurations available for both managed and unmanaged modules.
Requirements
The iMcV-DS3/E3/STS-LineTerm conforms to many DS3/E3/STS-based environments.
Ensure all of the relevant information about the expected installation environment is
available before configuring the module. This information includes
Distance of the coax run (450 feet Max)
Distance of the fiber run (Must match fiber transceiver selected)
Troubleshooting requirements
Windows Vista
Windows 7
In addition, there are Java versions of iView² for any Java-capable operating systems
such as Linux.
Please see the
SNMP
Management Module installation guide for software
configuration options.
Unmanaged Modules
Before installing the module in an unmanaged chassis, manually configure all of the
desired DIP Switch selectable features.
DIP Switches
The iMcV-DS3/E3/STS-LineTerm DIP Switches are located at S1 and S2 on the PCB.
The S2 DIP Switches are factory configured and must not be changed. The S1 DIP
Switches provide control over the available iMcV-DS3/E3/STS-LineTerm features.
The location of the S1 DIP Switches is displayed in the following diagram:
Managed Modules
The iMcV-DS3/E3/STS-LineTerm modules can be remotely managed when installed
in an iMediaChassis with an 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)
After the module is installed, modify the SNMP enabled features by using the iView
2
SNMP management software. In a managed chassis, the software settings take
priority over DIP Switch settings. Ensure 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.

The iMcV-DS3/E3/STS-LineTerm module features several diagnostic LEDs per port.
The LED functions are:
LEDs Next to Coax (BNC) Port
ER
LOS
Flashes yellow whenever a line code violation is
received.
Glows red when the BNC is receiving no signal and is in
an LOS ALARM state, resulting in sending an RAI signal
to the fiber port. If Fault Loopback is set to ON, then
AIS will also be sent to the Coax line as well.
Glows green when the BNC port receives a valid
Pseudorandom Bit Sequence. Off when the port is not
receiving a Pseudorandom Bit Sequence.
Glows yellow when the module is in either coax or fiber
loopback mode.
LEDs Next to Fiber Optic Port
ER
LOS
Glows yellow when a fiber symbol error has been
received.
Glows red when a link is not established and is in a LOS
ALARM state and will send an AIS signal to the BNC
Line. If Fault Loopback is enabled, then an RAI Signal is
also sent to the fiber line.
Glows green on the Remote Unit when set to DSW S1-
10. Glows green on the Local unit when it has
discovered a Remote management with Remote Unit
enabled.
Glows yellow when a Remote Alarm Indication is
received on the fiber port. When the fiber port receives
an RAI signal, this will force AIS to transmit on the COAX
Line.

Features
The iMcV-DS3/E3/STS-LineTerm module includes several features that allow it to be
configured for DS3, E3/STS, or STS-based environments.
4
5
Loopback (DIP Switch S1, Position 1)
This switch enables or disables the loopback feature. When this feature is enabled,
the data line (Coax or Fiber) set by the “Loopback Type” DIP Switch is looped back.
By default this feature is
DISABLED.
This feature can be controlled by SNMP management software (iView
2
) when the
iMcV-DS3/E3/STS-LineTerm module, configured as a HOST, is installed in a managed
chassis.
Loopback Type (DIP Switch S1, Position 2)
This switch identifies which data line is looped back when the Loopback DIP Switch
is enabled. The data line loopback selection can specify either a Fiber Loopback or a
Coax Loopback.
By default this feature is
COAX.
This feature can be controlled by SNMP management software (iView
2
) when the
HOST iMcV-DS3/E3/STS-LineTerm module is installed in a managed chassis.
Fault Loopback (DIP Switch S1, Position 4)
This switch enables or disables the Fault Loopback feature. A normal fault Loss Of
Signal (LOS) will cause an Alarm Indication Signal (AIS) to be sent on to the next line
segment. This feature provides for a fault condition to be sent back towards the
direction of the detected fault. In this way, both upstream and downstream craft
personnel are alerted to a single fault.
The Fault Loopback feature uses the iMcV-DS3/E3/STS-LineTerm module LEDs to
indicate that a loss of one strand of fiber has occurred. When a strand becomes
unavailable, the module at the receiver-end detects the LOS of the fiber link and
lights the LOS LED. The module then responds by sending a Remote Alarm
Indication (RAI) signal back to the Fiber line turning ON the RAI LED at the far end of
the line and sending AIS to the COAX Port. The RAI LED is now ON at the source of
the Fiber fault. By using the Fault Loopback Function, 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 M13 framed all-ones signal for DS3. For E3/STS and STS,
the AIS signal is an unframed all-ones pattern.
By default this feature is
ENABLED.
This feature can be controlled by SNMP management software (iView ) when the
HOST iMcV-DS3/E3/STS-LineTerm module is installed in a managed chassis.
2
Transmit LIU Waveshape (Line Build-Out) (DIP Switch S1, Position 5)
This switch selects the optimal transmit waveshape for the line build-out distance on
the coax line. The transmit waveshape can be set for a distance of either 0 to 255
feet or over 255 feet. This feature corrects problems related to cabling (i.e., cross-
talk, electromagnetic interference, etc). Improperly setting this switch will cause
signal degradation.
By default this feature is set to
0 to 255 feet
(450 ft maximum).
Transmit Coax Data Source (DIP Switch S1, Positions 6 & 7)
These switches select the transmit mode used by the iMcV-DS3/E3/STS-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
15
-1 PRBS Pattern)
These standard Telco transmission pattern modes are provided to help diagnose
transmission errors in the line.
By default this feature is set to
STANDARD DATA.
This feature can be controlled by SNMP-management software (iView
2
) when the
HOST iMcV-DS3/E3/STS-LineTerm module is installed in a managed chassis.
DS3, E3/STS and STS Selection (DIP Switch S1, Position 8)
This switch selects the data rate to use on the coax line. The data rate selections
available include the following:
DS3
(44.736 Mbps +/- 20 ppm)
E3/STS
(34.368 Mbps +/- 20 ppm)
STS
(51.840 Mbps +/- 20 ppm)
By default this feature is set to
DS3.
This feature can be selected only by setting the DIP Switches manually.
Remote Management (DIP Switch S1, Position 10)
This switch enables or disables the Remote Management mode. Enabling Remote
Management on the Remote module allows all SNMP configurable features for the
Remote modules to be configured from the Host module. By default this feature is
