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.
The IE-iMcV-T1-Mux/4 + Ethernet offers the following features: • • • • • • • • • • • • • • Four T1 ports with RJ-48 connectors One full bandwidth Ethernet 10/100BaseT port (specific model) 1+1 protection switching via two SFP-based optical ports (specific model) DDMI supported on SFP ports One end-to-end serial RS-232 port on an RJ-45 connector, supporting up to 120K baud rate Local CLI management console port on a Mini Jack connector Remote management capability through iMediaChassis series with SNMP Mana
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.
• • 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 IEiMcV-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.
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).
iView² Management Software iView² is the IMC Networks management software designed specifically for the IMC Networks “iMcV” family of modules. It features a GUI and gives network managers the ability to monitor and control the manageable IMC Networks 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.
LED Operation The IE-iMcV-T1-Mux/4 + Ethernet features diagnostic LEDs as explained below.
SFP Ports One model offers two SFP (A and B) ports for 1+1 protection; a second model offers one SFP without protection. ACT: • • • or LNK: • • Glows green when the SFP port is the active receive line.
DIP Switch Assignments DIP Switch Assignments A single 10-position DIP Switch is located on the unit to set the configuration. The switch positions are defined as follows: Switch # 1 2 3 4 5 6 7 8 9 10 Function Settings Factory Default Host/Remote Reserved Reserved Reserved Reserved Reserved Reserved Reserved Reserved Reserved OFF = Host, ON = Remote OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF OFF NOTE Switch #1 must be set to ON at the Remote location.
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, 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.
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.
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.
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.
Console Screens Configuration Using the Console Port The following section describes configuration using the console screens. The Remote module is only configured through the Host. Login Screen After running through an initial self test, the log-in screen is displayed (the diagnostic information displayed below is for illustration purposes only and may differ from the actual screen display): The username is case sensitive with a maximum length of 16 characters.
Main Menu From the main menu, the end-user can view essential unit configuration data and a clock indicating when the displayed information was last refreshed.
The screen displays the current status for items 1 through 8. For security reasons, the current username and password are not displayed. For items 1 through 8, enter the number of the menu item to be changed, and then enter the new value when prompted. The unit and port names can be assigned by the end-user and are used in SNMP associated TRAP alarm messages. Port Alarm Status Screen The Port Alarm Status screen displays the status of the Host and Remote alarms on each of the unit's ports.
SFP Line Status Screen The SFP Line Status screen displays the status of the Host and Remote SFP links. The detailed SFP information may be viewed by entering "1" for SFP A or "2" for SFP B. Displayed data includes the manufacturer name, code, part number and revision number. These values may not be modified. For SFP modules that support DDMI values for temperature, voltage, diode current and optical receive/transmit, levels can be obtained through SNMP Management Module.
Enter the number of the menu item to change its configuration, and then enter the new value(s) when prompted. Ethernet Port Status Screen This screen displays the current Ethernet port status for both the Host and Remote site. T1 Port Configuration Screen Use this screen to access the loopback and name details for each of the four T1 ports. Enter the number of the menu item to edit, and enter the new value(s) when prompted.
Host T1 Port Setup Screen Enter the number of the menu item to edit, and enter the new value(s) when prompted. T1 Port Status Screen Use this screen to display the current status for each of the four T1 ports for the Host and Remote units.
Fiber Optic Port Verification As a troubleshooting aid, the fiber optic ports can be verified by placing a physical loopback optical line on the ports and verify the LED behavior as shown: The ACT LED will arbitrarily be configured to either the A or B fiber line. The RAI LED is RED/GREEN indicating that there is something wrong at the far end of the fiber line (in this case, the remote unit is missing). The ALARM LED is RED because the T1 port is not connected.
T1 Port Verification By placing a physical loopback connection on the T1 port, a valid signal can be detected by each individual T1 port to verify its operation. Without the fiber looped, the ALARM LED for the looped T1 port will show RED/GREEN indicating there is a problem at the far end of the fiber transport (In this case the far end unit is missing) and the STAT LED is RED because the fiber is in LOS. With the fiber looped, the T1 port will only show a normal GREEN STAT LED.

RS-232 Serial Console Port The following table lists the pin configuration for the RS-232 3-pin Mini Jack mating connector for the console serial port.
Troubleshooting • All IE-iMcV-T1-Mux/4 + Ethernet units are shipped configured as Host units via DIP Switch #1 = OFF. The Remote unit should be set to DIP Switch #1 = ON. Be sure to confirm that the iMcV-T1-Mux/4 card is set correctly when used. • The fiber transport is independent of all other ports and should be established first. If this is not possible, a physical fiber loopback can be used for fiber port verification. A fiber loopback will cause all connected ports to loop back their respected data.
