Introduction

The FRM220A-Eoe1/G is a single E1 Bridge for the FRM220/220A Series

Platform Media Converter Rack. The converter supports Ethernet

transmission over Framed/Unframed E1 using GFP-F (Generic Framing

Procedure-Framed). The clock source may be selected internally or

recovered from any one of the received E1 signals. The Ethernet port

utilizes a single RJ-45 connector or SFP for optical fiber, depending on

model. One single model supports either unbalanced 75 ohm via BNC

connectors or balanced 120 ohm via RJ-45. When the FRM220A-Eoe1/G

card is placed in the FRM220A rack with GSW/SNMP management, the

management can view the converter card's status, type, version, Ethernet

link status and alarms. The card can be configured to enable or disable the

port, reset the card, set clocking, Ethernet mode and provide E1 analog

diagnostic loopbacks. A unique feature of the FRM220A-Eoe1/G is the use

of a common card design which may either be inserted in an appropriate

single or dual slot chassis as a stand-alone modem or as a card when

placed in the FRM220A-CH20 In-band managed rack.

Features

• Standalone or card type Ethernet over E1 converter.

• Uplinks 100M Ethernet to aggregate trunk card of FRM220A

Management Features

The FRM220-Eoe1/G has one on-board 2 pole DIP Switch which can be

used to configure the device timing source (recovery or internal) and the

framing mode. When placed in a stand-alone chassis with DB9 console

port, these devices support a text based serial terminal with an easy to use

menu system for configuration. When placed in a managed chassis, the

card is configured and monitored through the chassis NMC (network

management controller) via console, Telnet, Web HTTP or SNMP.

Applications

The FRM220A-Eoe1/G E1 LAN Bridge works in point-to-point

applications, either as a stand-alone (in CH01, 02, 04) or when placed in

the CH20 managed rack.

Ethernet over E1

Typical Point-to-Point Application

The E1 transmission signal traditionally has been used to carry voice

within the Public Switched Telephone Network. With the emergence of IP,

E1 has also found use as a carrier for Data. A single E1 is able to carry

Ethernet data by using HDLC (High-level Data Link Control) WAN

encapsulation. The FRM220A-Eoe1/G is also able to use GFP-F to send

the Layer 2 Ethernet over the Layer 1 E1 transmission medium. A carrier

can then use this transparent Ethernet to connect to a customer owned

broadband router. The FRM220A-Eoe1/G supports GFP-F according to

ITU-T G.7041.

Console Management

When placed in the 1-slot CH01M or 2-slot CH02M chassis, this card can

be locally managed by connecting a simple serial terminal such as a

notebook computer that has an RS232 port or via a commonly available

USB to RS232 adapter. In Windows XP, HyperTerminal™ is an application

available for emulating a serial terminal. You can also search for TeraTerm

or PuTTY which are free alternatives, especially if the operating system is

Vista or Win7.

Settings

Baud Rate: 38,400 | Data bits: 8 | Parity bits: none | Stop bits: 1

Handshaking: none | Emulation: VT-100

Connect the serial cable to the DB9. Run the terminal emulation program.

With power on, press [ESC] or [Enter] to display the "Main Menu" screen.

The following is an example.

Status Indications

E1 Status Alarms

LOS (Loss Of Signal) – LOS is indicated when the E1 receive circuitry

detects no signal or if the signal level drops below usable threshold.

AIS (Alarm Indication Signal) – AIS is an unframed, 'all ones' pattern

which is generated at E1 Tx whenever the Rx experiences LOS. This

allows the local device to report an LOS condition to the remote device.

AIS is specified in ITU-T G.775 Recommendation.

LOF (Loss Of Framing) – If an E1 receive has a long un-terminated

connection, it may not indicate an LOS (due to antennae effect).

However, if the bit stream does not contain the proper framing

information, an LOF will be indicated.

LOMF (Loss Of Multi-Frame) – The framing structure for E1 is defined

in ITU-T G.704 Recommendation. Multi-frames are typically generated

when E1 is used for voice communication. This alarm is issued in the

event of multi-frame error or loss.

RAI (Remote Alarm Indication) – Sometimes referred to as 'Yellow'

alarm, the RAI (remote alarm indication) signal indicates loss of layer 1

capability at the user-network interface.

CRC (Cyclic Redundancy Check) - This alarm appears when the Cyclic

Redundancy Check (CRC) fails.

BPV (Bi-Polar Violation) - This alarm normally appears when there are

Layer 1 issues or problems with line coding.

Loop - This alarm appears when an E1 loop is detected (loop detection

must not be disabled).

LAN Status

LAN Link (Up/Down) – Link Up indicates the LAN is linked to another

active Ethernet device.

Auto Negotiation (Auto/Manual) – The default is auto with speed auto

detected and Duplex negotiated per IEEE802.3u.

Speed (10/100) – This indicates the auto detected speed or the manually

set speed of the Ethernet.

Duplex (Full/Half) – This indicates the negotiated or manually set

Ethernet Duplex mode.

Flow Control (Enable/Disable) – Flow control is defined in IEEE802.3X.

Active (Enable/Disable) – This indicates the LAN port setting. Disabling

the port will block all traffic.

Operation

Select any of the menu items by keying in the menu item number or letter.

Use the [ESC] to return to a previous menu. Settings are not applied to the

cards circuitry until save operation is performed. After all of the parameter

settings have been selected, press "s" from the main menu to save the

parameters in non-volatile RAM (NVR).

Explanation of Settings

1. Parameter Settings: This will call a sub-menu for setting E1, LAN and

GFP parameters.

2. BERT: This will call a sub-menu for Bit Error Rate Testing of E1 channel.

3. Timing Source: The timing source can be selected from received E1

signal or from an internal reference oscillator.

4. Local/Remote: When in-band management is enabled, this menu item

can switch to the remote unit for configuration.

5. Failover: When E1 Failover feature is enabled, if the E1 line disconnects,

local and remote device electrical or optical Ethernet port will show link

down. In this way, the E1 link state can be checked through the state of the

optical or electrical Ethernet.

6. Config Priority: This toggles between reading the DIP switch or making

settings and saving in Flash. The DIP controls framing and timing settings.

7. VLAN Set: This sub-menu allows enabling the VLAN tag function and

assigns the VID to the LAN port. Packets which egress the LAN are

untagged while packets that ingress will be tagged with the set VID.

8. RMON: The Remote Network MONitoring (RMON) MIB was developed

by the IETF to support monitoring and protocol analysis of LANs. This sub-

menu allows enabling, reading and clearing the RMON tables for the LAN

port's transmit and receive.

A. Encapsulation: This unit supports both GFP and HDLC encapsulation

methods. Both units in the E1 link must be set to the same method.

B. Net Manage: The in-band management uses Sa bits 4-8 of the E1. If a

particular bit is required for another application, switch to out-band.

Q. Quit: This exits the terminal program.

S. Save: After settings are made they need to be saved. Use this

command.

D. Default: This will return the unit to factory default settings.

U. Online Upgrade: When stand-alone, the upgrade function is only

applicable in the factory. Users perform upgrade by placing the Eoe1 into a

managed chassis, such as CH20 with NMC.

Loop back Test:

This FRM220A-Eoe1/G converter incorporates loop back features which

allow loop back testing to confirm that the E1 loop is operating normally or

not. Ethernet loopback cannot be supported. (Ethernet looped would cause

a broadcast storm.) Therefore, only loop back that specifically can test the

E1 links is supported in this model.
