ABOUT THE IE-IMCV-T1-MUX/4+ETHERNET
The IE-iMcV-T1-Mux/4 + Ethernet is a media converter that transports four
independent T1 lines over an existing single (or dual, “1+1”) standard fiber
optic line operating at an effective rate of 155Mbps. One serial link (RS-232)
and one Ethernet (10/100BaseT) connection are multiplexed onto the fiber
link(s). Each of these communication channels is transported end-to-end at full
wire speed with very low latency. A maximum packet size of up to 1916 bytes
is supported on the Ethernet port.
The serial link can be used for extending an independent RS-232 interface to
the remote POP location for use in managing or controlling other devices at
the POP and supports any data rate up to 120Kbps. In addition, each unit
supports an RS-232 console port for local configuration by technical support
personnel. The console port is used for end-to-end system management, fault
detection/isolation and system diagnostics.
The IE-iMcV-T1-Mux/4 + Ethernet provides fault indications on the T1 and
fiber links resulting from real-time active faults. The equipment detects both T1
and fiber LOS events as well as degraded T1 or fiber lines. The unit will
automatically forward AIS signaling to the remote unit after detecting a LOS
(Loss Of Signal) condition on any incoming T1 line. Severe receive optical link
failures will result in the automatic generation of AIS signaling onto the T1
lines connected to the unit receiving the corrupted optical signal.
In addition, Code Violation (CV) errors are detected on all incoming T1 lines
and BER calculations for the optical line are constantly being performed by
circuitry within the unit's optical receiver. Error conditions are displayed on the
unit’s front panel LED indicators and reported to system management
software (if equipped) where more detailed error information can be displayed
on the user’s Graphical User Interface (GUI).
Modules equipped with 1+1 fiber redundancy can benefit from the enhanced
reliability of a protected fiber link and the system’s ability to automatically
switch to the “best” fiber line should one line become impaired or fail. This
automatic switchover capability is designed to occur rapidly (<50
milliseconds), minimizing data loss and system down time. In addition,
automatic switchover can be overridden, allowing the end-user to force the
unit to receive on a specific optical line if desired to support periodic
maintenance.

MANAGED MODULES
The IE-iMcV-T1-Mux/4 + Ethernet modules are installed as a Host/Remote
pair; the fiber connection is B+B proprietary. Host or Remote configuration is
selected by an onboard DIP Switch setting. The Host/Remote pair can be
remotely managed when the HOST is installed in an iMediaChassis with an
SNMP Management Module.
CONFIGURATION CONTROL
Some iMcV modules offer Configuration Control. Configuration Control has been
implemented to assist the end user by retaining the latest configuration
regardless of how that configuration was implemented (via DIP Switch settings or
SNMP), when an SNMP Management Module is present in a managed chassis.
Historically, if an SNMP Management Module was installed in a chassis, SNMP
would override the DIP Switch settings of a module. Utilizing Configuration
Control, the end user has three conditions under which the configuration of an
iMcV modules may be impacted:
•Changing or installing an SNMP Management Module into a chassis with an
IE-iMcV-T1-Mux/4 + Ethernet populated in a chassis.
-The IE-iMcV-T1-Mux/4 + Ethernet will transfer its saved configurations
to the SNMP Management Module. If there is no SNMP Management
Module, the IE-iMcV-T1-Mux/4 + Ethernet will function based on its DIP
Switch settings. If the DIP Switches have not been changed, the stored
configuration on the unit will be used. The stored configuration can be
retrieved from the SNMP Management Module or the DIP Switches.
•Replacing the same type of iMcV modules.
-If the DIP Switch settings are the same as the settings on the removed
IE-iMcV-T1-Mux/4 + Ethernet, the new IE-iMcV-T1-Mux/4 + Ethernet
gets its configuration settings from the SNMP Management Module.
-If the DIP Switch settings are different, then the configuration of the
module is determined by the DIP Switch settings. The settings are
forwarded to the SNMP Management Module and the values are saved.
•Installing a different model of iMcV module.
-If another type of module is installed into the same slot in a chassis, the
SNMP Management Module clears the memory of the previous
configuration for that slot. The installed iMcV module configures itself
and its configuration is forwarded to the SNMP Management Module,
where the values are saved.
The SNMP Write Lock switch does not impact any iMcV modules or IE-iMcV
modules with Configuration Control. Removing and installing a new SNMP
Management Module will no longer impact these modules, either. However, if

IE-iMcV-T1-Mux/4+Ethernet
8
there is a mixture of iMcV modules, with and without Configuration Control, the
Write Lock Switch and a new SNMP Management Module must be taken into
consideration.
If the command cleandb is applied to an SNMP Management Module, all the
settings for the modules will be removed; but the Configuration Control modules
will still be based on the last change made. Those without Configuration Control
will be set to their default settings.
NOTE: If the end user has a mixture of standard iMcV modules as well as Configuration Control iMcV modules,
it is important to understand how SNMP and DIP Switches will impact the cards depending on their capability.
Standard iMcV modules cannot be upgraded to Configuration Control capability, so it is strongly recommended
to set the DIP Switches on the modules and then configure them via software to match the same settings.
1+1 PROTECTION ON FIBER INTERFACE MODE
The fiber transport is a 1+1 protection switched transport. It provides very fast (<50 mSec)
switch-to-protect timing by transmitting the same information on both fibers at the same
time. The fiber receiver then chooses the fiber to receive based on the validity of the line.
Once the selection is made, the receiver will stay on that fiber line until it enters a fiber
defect state at which time another fiber selection process is started (non-revertive
switching). Once a switch-to-protect has occurred, a hold off time (1 second minimum) is
used to prevent another switch-to-protect from occurring too soon after a protection
switch.
If protection is not enabled, SFP Port A will be used by default and no alarm or defect
information will be provided for SFP Port B. The LEDs associated with the backup fiber
line will only be active if protection is enabled.
When protection is enabled, error reporting for the backup fiber line is limited to the Signal
LOS condition. Signal LOS will generate an SFP Down Trap.
A Remote Alarm Indication (RAI-F) signal is sent back to the fiber if the received fiber is in
BER or LOS defect condition. In this way, the far end unit is alerted of a fault condition on
the local fiber line.

SERIAL PORT CONNECTION
The IE-iMcV-T1-Mux/4 + Ethernet includes a console serial port. To establish a link between a
module's console port and a local PC, connect the Mini Jack to DB9 adapter (optional
accessory available through B+B SmartWorx, part number 825-39950). This RS-232 serial
connection provides access to the IE-iMcV-T1-Mux/4 + Ethernet module CLI configuration
screens. Set the computer/terminal for
VT-100 emulation , 38.4K baud , 8 data bits , 1 stop
bit , no parity and no flow control . Under the VT-100 emulation, set the backspace key to
send delete .

INSTALLATION INSTRUCTIONS
Each IE-iMcV-T1-Mux/4 + Ethernet module requires two slots in an iMedia
Chassis series, MediaChassis/2 series, or IE-MediaChassis/2 series. To install
the module in a chassis:
1. Remove the blank faceplates covering the slots where the module is
to be installed.
2. Then slide the module into the chassis card guides until the module
is seated securely in the slots.
3. Secure the module to the chassis by tightening the captive screw.
All IE-iMcV-T1-Mux/4 + Ethernet units are shipped from the factory configured
as Host units. The IE-iMcV-T1-Mux/4 + Ethernet modules must be installed in
pairs. For two IE-iMcV-T1-Mux/4 + Ethernet units to properly operate together
one unit needs to be configured as a Remote. Configuration as a Host or
Remote is controlled via a DIP Switch setting (S1-1).
NOTE: Some options require items that are sold separately, available from B+B SmartWorx.
SMALL FORM-FACTOR PLUGGABLE PORTS (SFP)
The fiber link on the IE-iMcV-T1-Mux/4 + Ethernet module is supported
through one or two SFPs (depending on model) running at 155Mbps. Many
SFPs, including those from B+B SmartWorx, feature enhanced diagnostics
capabilities Data and Diagnostic Management Information (DDMI). DDMI
statistics provide real-time access to transceiver operating parameters such as
voltage, temperature, laser bias current, and both transmitted and received
optical power. DDMI information can be accessed in iView2. Any MSA-
compliant SFP, 155mbps, can be installed in one or both SFP ports (model
specific).
AUTOCROSS FEATURE
The 10/100BaseT Ethernet port on the IE-iMcV-T1-Mux/4 + Ethernet includes
an AutoCross feature that automatically selects between a crossover
workstation and a straight-through connection depending on the connected
device.

IE-iMcV-T1-Mux/4+Ethernet

CONFIGURATION OPTIONS
The following sections describe the configurable features.
From the CLI "Unit Configuration," use the "Factory Default" command to
restore the unit's default settings in the CLI, under Unit Configuration. This
restores the card's default configuration and resets the default username and
password.
User: admin / Password: admin
ETHERNET PORT
If the Ethernet port is not used, it can be set to disabled via a console session
or via iView², to effectively block all traffic on this port.
PACKET SIZE
The Ethernet port can accommodate packets up to 1916 bytes.
AUTO NEGOTIATION
The IE-iMcV-T1-Mux/4 + Ethernet ships from the factory with Auto Negotiation
enabled on the Ethernet port. In this mode, the port negotiates for speed,
duplex and flow control.
FORCING SPEED, DUPLEX MODE, FLOW CONTROL
The Ethernet port on the IE-iMcV-T1-Mux/4 + Ethernet can be selectively
advertised or manually forced for 10 Mbps or 100 Mbps operation at Half- or
Full-Duplex (i.e., 10 Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-
Duplex, etc.). Flow control can also be enabled on the Ethernet port when the
connecting equipment supports this. These features can be enabled through
iView²/CLI.
BANDWIDTH CONTROL
The IE-iMcV-T1-Mux/4 + Ethernet includes bi-directional bandwidth control in
32 Kbps increments (configurable via iView2).
FX LINKLOSS AND LFPT
During normal operation, link integrity pulses are transmitted by all point-to-
point Ethernet devices. When an IE-iMcV-T1-Mux/4 + Ethernet receives valid
link pulses, it knows that the device to which it is connected is up/acyive, and

IE-iMcV-T1-Mux/4+Ethernet
15
that the cable coming from that device is intact. The appropriate “LNK” (link)
LED is lit to indicate this. However, these signals are not normally transmitted
across a normal store-and-forward Ethernet bridge function. A failed Ethernet
line on one end of the fiber link is not forwarded to the Ethernet port at the
other end of the optical transport. A failed optical line is also not normally
forwarded to the Ethernet port. The FX LinkLoss and LFPT functions are used
to enable these features. Both the LinkLoss and LFPT features are set to
"Disabled" by default.
FX LINKLOSS (FXLL)
FX LinkLoss is a link integrity monitoring feature that forwards fiber link faults
to the RJ-45 Data port to indicate that a fiber link fault has occurred. FX
LinkLoss can be enabled in iView²/CLI.
FIBER FAULT LOOPBACK (FFL)
When a Fiber LOS is detected, the unit sends a Remote Alarm Indication back
to the fiber in the opposite direction. The reception of fault indication on the
fiber line inhibits sending a LINK signal to the Ethernet port. This function can
be enabled at both ends of the fiber line without causing a "lock-up" condition
and will automatically clear when the fault is cleared. FFL can be configured at
both ends of the fiber line with no lock-up condition.
LAST GASP
The iMcV-FiberLinX-II includes a Last Gasp feature, that sends a trap Flinx
Unit Down for the Host unit or a Flinx Remote Unit Down for the Remote unit
(as seen in iView²) when the power to the module fails.
T1 PORTS
ALARM LEVEL
T1 lines are defined as LOST when no signal is received as defined by ITU
G.775 specifications Loss Of Signal (LOS), and are considered in error with a
BER of 10^-6. If either of these conditions lasts for more than 2.5 seconds, an
ALARM state is declared. This error condition must be absent for 10 seconds
for the alarm state to clear.
The starting and ending event of all alarm conditions will generate an SNMP
TRAP when the unit is installed in a managed chassis and set to the in service
state. During initial installation or normal maintenance, the end-user can place
the unit in the Out-Of-Service (OOS) state to inhibit unwanted SNMP TRAP
alarms.

IE-iMcV-T1-Mux/4+Ethernet
16
ALARM CONDITIONS
•Last gasp (remote lost power)
•T1 Port Up
•T1 Port LOS
•Fiber port Up / LOS
•SFP removed/installed
•Service state change
LOOPBACK
Each T1 port can be tested in loopback mode by enabling either a Host loopback
or Remote loopback test path. This capability allows the end-user to help
troubleshoot and isolate system problems such as improper/broken line
terminations, cables or malfunctioning equipment.
With Host loopback, the T1 copper port, connected to the Host unit, is looped
back to that port within the local unit. T1 data coming from the remote unit to that
port over the optical link is also looped back to the remote unit at the same point
within the local unit.
With remote loopback, a T1 line connected to the Host unit is transported onto
the optical link and looped back within the remote unit back onto the optical link
without passing onto the copper T1 line of the remote unit. The remote’s
incoming T1 copper line is also looped back to the copper line within the remote
unit. The default value for loopback is "none."
