About the IE-iMcV-E1-Mux/4

Overview

The IE-iMcV-E1-Mux/4 is a media converter that transports four independent E1 lines
over an existing standard 155Mbps-capable fiber optic line operating at an effective
rate of 150Mbps. A second SFP port is available for a 1+1 protection mode. One
serial link (RS-232) and one Ethernet (10/100BaseT) connection are also multiplexed
onto the fiber link(s). Each of these communication channels is transported end-to­end at full wire speed with very low latencies.

The serial link can be used for extending an independent RS-232 interface to the
remote Points of Presence (
devices at the

POP

and supports any data rate up to 120K baud. In addition, each

POP)

location for use in managing or controlling other

unit also supports an RS-232 console port for local configuration by technical support
personnel. Both of these serial links are used for end-to-end system management,
fault detection /isolation and system diagnostics. The remote serial offers serial only.

The IE-iMcV-E1-Mux/4 provides fault indications on the E1 and fiber links resulting
from real-time active faults. The equipment detects both E1 and fiber
well as degraded E1 or fiber lines. The unit will automatically forward

LOS

the remote unit after detecting an

(Loss Of Signal) condition on any incoming E1

line. Severe receive optical link failures will result in the automatic generation of

LOS

events as

signal.

In addition,

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;
this allows the end-user to force the unit to receive on a specific optical line if desired
for testing.

Installation Instructions

Each IE-iMcV-E1-Mux/4 module requires two adjacent slots in an iMediaChassis or
MediaChassis. To install the module in a chassis, remove the blank faceplates
covering the slots where the module is to be installed. Then slide the module into
the chassis card guides until the module is seated securely in the slots. Secure the
module to the chassis by tightening the captive screw.

Host

All IE-iMcV-E1-Mux/4 units are shipped from the factory configured as

units.
The IE-iMcV-E1-Mux/4 modules must be installed in pairs. For two IE-iMcV-E1­Mux/4 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). If installing in a managed chassis, set the card in the managed chassis as a HOST.

User: admin / Password: admin

Ethernet Line Setup

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 transport can accommodate packets up to 1916 bytes.

Auto Negotiation

The IE-iMcV-E1-Mux/4 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 the Speed, Duplex Mode, and Flow Control

The Ethernet port on the IE-iMcV-E1-Mux/4 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 or the serial port.

FX LinkLoss and

LFPT

During normal operation, link integrity pulses are transmitted by all point-to-point
Ethernet devices. When an IE-iMcV-E1-Mux/4 receives valid link pulses, it knows
that the device to which it is connected is up, and 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.

For troubleshooting information utilizing the FX LinkLoss and
iMcV-E1-Mux/4 modules, refer to

Last Gasp

This feature alerts the end user if power to the device fails, and is permanently
enabled. Since the IE-iMcV-E1-Mux/4 modules must be installed as a Host/Remote
pair, the Host will report a power failure by sending an alarm trap to management.
The Host will maintain the Last Gasp alarm state until it can verify that power has
been restored.

Unit Service State

When selecting In-Service, Traps reporting is enabled. If Out-of-Service is selected,
Traps reporting is disabled. A Trap is sent when the status is changed from
Enabled/Disabled or Disabled/Enabled.

E1 Port Equipment

Within each E1 port setup, the state of the port can be set to equip or not-equipped.
When set to not-equipped, the end user has the ability to perform maintenance on
the line without impacting the other parts on the module.

13

Loopback

Each E1 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 E1 copper port, connected to the Host unit, is looped back
to that port within the local unit. E1 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, an E1 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 E1 line of the remote unit. The remote’s incoming
E1 copper line is also looped-back to the copper line within the remote unit.

The default value for loopback is "none."

WARNING

An optical loopback will also loop back the Ethernet port. If the network cannot
tolerate this, remove the Ethernet port connection before connecting the fiber
loopback.

E1 Port Verification

By placing a physical loopback connection on the E1 port, a valid signal can be
detected by each individual E1 port to verify its operation. Without the fiber looped,

Fiber Optic Cleaning Guidelines

Fiber Optic transmitters and receivers are extremely susceptible to contamination by
particles of dirt or dust, which can obstruct the optic path and cause performance
degradation. Good system performance requires clean optics and connector ferrules.

Use fiber patch cords (or connectors, as appropriate) only from a reputable

1.

supplier; low-quality components can cause many hard-to-diagnose problems in
an installation.

2. Dust caps are installed at IMC Networks to ensure factory-clean optical devices.

These protective caps should not be removed until the moment of connecting
the fiber cable to the device. Should it be necessary to disconnect the fiber
device, reinstall the protective dust caps.

Store spare caps in a dust-free environment such as a sealed plastic bag or box

3.

so that when reinstalled they do not introduce any contamination to the optics.

If it is suspected that the optics have been contaminated, alternate between

4.

blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.

Electrostatic Discharge Precautions

Electrostatic discharge (ESD) can cause damage to any product, add-in modules or
stand alone units, containing electronic components. Always observe the following
precautions when installing or handling these kinds of products

Do not remove unit from its protective packaging until ready to install.

1.

Wear an ESD wrist grounding strap before handling any module or component.

2.

If the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.

Hold the units by the edges; do not touch the electronic components or gold

3.

connectors.

After removal, always place the boards on a grounded, static-free surface, ESD

4.

pad or in a proper ESD bag. Do not slide the modules or stand alone units over
any surface.

WARNING!

Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.

Definition of Terms/Acronyms

The following are terms and phrases used within this manual (shown in
which are found in documents associated with this equipment.

1+1

The Term “1+1” refers to line protection where identical
information is transmitted on two redundant lines. The Receiver

BER

of the line.

AIS

chooses the “best” line to use based on the

Alarm Indication Signal: Used in E1 signaling, the AIS is a
predetermined bit stream (all ones) that is transmitted (forwarded)
upon the loss of an incoming E1 signal or when the E1 signal is
disrupted.

AN

Auto Negotiation: A signaling protocol used by an Ethernet PHY to
determine the characteristics (speed, duplex mode) of its “link

BER

partner” and configure itself automatically

Bit Error Rate: The percentage of bits with errors divided by the
total number of bits that have been transmitted, received or
processed over a one second time period.

CLI

Command Line Interface: An interface screen, often DOS-based,
used for system management and diagnostics requiring the user to

GUI

type commands rather than use a

CV

DDMI

FFL

GUI

HDB3

IS

Code Violation: An anomaly of a decoded physical-layer signal
stream resulting in coding (signaling) error(s). Noise bursts or
intermittent connections on a link are the usual causes of code
violations; an

HDB3

coding error.

Digital Diagnostic Monitor Interface: A defined serial interface and
data format typically used to access SFP internal information

Fiber Fault Loopback: When the fiber line fails, the Ethernet port
that is being forwarded over the fiber line is forced out of LINK.
Similar to the Fiber Alert function.

Graphical User Interface: Software that provides a visual interface
to enable an end-user to manage and monitor network devices.

High Density Bipolar 3 Coding: A physical-layer signal encoding
scheme defined for E1 transmission which ensures sufficient
signaling transitions for robust clock/data recovery.

In-Service stat is the normal state of an active port with normal
error reporting.

29

LED

Light Emitting Diode: A small stack of lights to indicate link,
duplex or other options.

LFPT

LOF

LOS

MDI/MDIX

MIB

MSA

Link Fault Pass-Through: LFPT can be enabled via iView² or
through the console port.

Loss Of Frame: An error condition where the receiver/decoder
misses detection of the framing signal.

Loss Of Signal: An error condition where the receiving line
interface unit does not detect a signal.

Media-Dependent Interface/ Media-Dependent Interface
Crossover. The ability of an Ethernet port to automatically detect
and configure its cabling connections to accommodate crossover
or non-crossover wiring, depending on its link partner and cabling.

Management Information Base: A database of objects that can be
monitored by a network management system. Both SNMP and
RMON use standardized MIB formats that allow any SNMP and
RMON tools to monitor any device defined by a MIB.

Multi-Source Agreement (SFP): The standard an SFP must meet to
be compatible in network devices.

OOS

POP

RAI

SFP

SNMP

Out-Of-Service, OOS is used by the CRAFT personnel to turn OFF
the alarm reporting so they can service the line without causing
alarm TRAPS to be sent to the NOC Center. The LEDs display a
line status but do not report any line related alarms back to the
NOC. A card removal or insertion is still reported, but a PORT
up/down or changes to its configuration are not.

Point(s) Of Presence: The demarcation point where carrier owned
equipment is located at the customer site.

Remote Alarm Indication: Status information received from the
line indicating there is an alarm condition at the far end of the
transport.

Small Form-Factor Pluggable: An industry standard optical
pluggable module.

Simple Network Management Protocol: A set of protocols for
managing complex networks over a standards-based IP network.
