About the IE-iMcV-T1-Mux/4 + Ethernet

Overview

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 also 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 also 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 an

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

LED

unit's optical receiver. Error conditions are displayed on the unit’s front panel 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).

1+1

Modules equipped with

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; this allows the end-user to force the unit to receive on a specific optical line if desired to support periodic maintenance.

The IE-iMcV-T1-Mux/4 + Ethernet offers the following features:

• Four T1 ports with RJ-48 connectors

Product Application

The

IE-iMcV-T1-Mux/4 + Ethernet delivers 4 T1 lines to a customer's site over a protected, dedicated fiber line. In addition, one serial RS-232 line and one 10/100BaseT Ethernet line can be carried at the same time. All configurations run at full line rates with no interaction.

Managed Modules

The

IE-iMcV-T1-Mux/4 + Ethernet modules are installed as a Host/Remote pair; the fiber connection is IMC 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; labels on the front faceplate are identified as such. 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-Module 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-Module

• 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 an 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-Module or IE-iMcV-Module with Configuration Control. Removing and installing a new SNMP Management Module will no longer impact these modules, either. However, if 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 the 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.
