Chapter 1 Introduction

The FM-60 is a flexible transmission system, which provides voice and data

applications by time division multiplexing and de-multiplexing on 2.048 Mbps E1

signals. Timeslot interchange (TSI) technique is applied to provide timeslot

assignment and timeslot interchange capability, so that any 64 Kbps or Nx64 Kbps

user signals can be assigned and cross-connected to any E1 timeslot(s).

The FM-60 has a compact design. It is equipped with 18 slots for various units.

Three of them are for common units, and the remaining fifteen slots are for

channel units. The channel units provide versatile user services. All the channel

units are hot-swappable, and different types of channel units can be placed in the

FM-60 simultaneously with arbitrary combination.

The FM-60 features powerful diagnostic capabilities. Several types of loopbacks

can be activated for the units.

Featured with a built-in SNMP agent, the FM-60 supports network management

for operation, administration, maintenance, and provision. It can be managed

through user-friendly GUI management software. FM-60 is equipped with two

RS-232 ports and one Ethernet port for management. Moreover, the FM-60

supports remote management capability, which allows it to be managed over

in-band E1 timeslot. Accompanied with the static routing function, management

messages can be routed from one FM-60 to next FM-60 over E1 line, so that the

remote management capability can be greatly extended.

The FM-60 also provides the function of remote control with CT-128 Multiple-Rate

NTU and CT-50 Subrate NTU. When the CT-128 or the CT-50 is connected to the

FM-60, it can be remotely controlled by the network management system.

1.2 System Diagram

The FM-60 consists of customer interface units (channel units), one E1 line

interface unit (ELIU or ELIU2), one maintenance and control unit (EMCU-B), and

two power supply units (EPSU).

The digital or analog user signals from the customer loops are terminated by

channel units (CU), and are then transmitted to the EMCU-B. Time slot

interchange for transmitting the CU data to the desired E1 time slots or to other

CU locations is performed inside the EMCU-B by the time slot interchange (TSI).

Interchanged data is sent to the ELIU/ELIU2 for transmitting data to the

corresponding time slots on E1 lines.

The FM-60 timing sources can be generated from a 2.048 MHz external clock,

received E1 lines, and internal oscillator. The EMCU-B selects one of these clock

sources and connects it to the phase lock loop (PLL) inside EMCU-B to derive

system synchronization clocks of FM-60. The EMCU-B also generates a 2.048

MHz output clock.

2.2.2 Installation

Before installation, make sure no card resides in the chassis. Then, do as follows.

STEP 1 Connect the power source to either JDU1 and JDU2 or both.

!" Connect chassis frame ground to the FG pin.

!" Connect –48V ground to the PG pin.

!" Connect –48V to the –48V pin.

STEP 2 Insert the EPSU in either of the EPSU slots. Fasten the unit in the

slot with the locking handles at both ends on the faceplate.

STEP 3 Measure the jacks on the EPSU faceplate and estimate if the power is

correctly supplied to the channel units.

STEP 4 Adjust the CID and Console DIP switches on the rear panel to a

desired data rate. An alternative is to do this after the EMCU-B is

inserted, but then also reset the EMCU-B (push the faceplate Reset

button). During the reset process, the traffic on the channel units

will be interrupted.

STEP 5 Insert the EMCU-B into the EMCU slot. Fasten the unit in the slot

with the locking handles at both ends on the faceplate.

STEP 6 Install the ELIU/ELIU2. Before sliding the card into the ELIU slot,

first select an E1 interface (BNC or wire strap pins) using the onboard

jumpers. The jumper setting is introduced in the later chapter of

ELIU/ELIU2. Use the locking handles at both ends on the faceplate

to fasten the unit.

STEP 7 Connect to the E1 connectors. Note that ELIU2 can connect 1st E1

and 2nd only.

STEP 8 To use an external clock, connect the external clock wire to the

Ext_CLK (I) connector.

STEP 9 To output the FM-60 clock, connect the Ext_CLK (O) connector.

faceplate, DB-9 or DB-25 connectors are provided to connect to customer end and

screws and locking handles are provided on the faceplate for fasten purpose.

When you face the chassis, the channel units are on your left side and are labeled

slot 1 to slot 15 respectively. Each channel unit is equipped with locking handles

at both ends on the faceplate for fasten purpose.

2.3.2 Installation

Each channel unit has the same installation procedures. The chassis (including

power) and common units should be installed prior to the channel units.

STEP 1 Verify if any hardware jumper or DIP switch should be set. Few

channel units, e.g., EEM2 has jumpers to set.

STEP 2 Slide a channel unit in an available slot (Slot 1 to Slot 15). Make sure

it fits into the backplane connector. Do not mis-put it into a

common unit slot.

STEP 3 Press the locking handles at both ends to fasten the unit into the slot.

Note 1: If a slot is meant to remain empty, it is recommended to use a dummy

face panel to cover the slot to keep possible objects, dust, or liquid fromentering the equipment. Any of the element may do damage to the

circuit board or equipment.

Note 2: Make sure all units fit in the slots.

!" For the ELTU, it can be connected to E1 only.

Before you start to read the chapter, be familiar with the following terms that will

help to understand this chapter.

!" Source Time Slot: It is the source of data. A Source TS can transmit data

to numerous destinations (also called Destination Time Slot).

!" Destination Time Slot: It is the destination of the data sent by the Source

Time Slot. A Destination Time Slot can be assigned to only one Source Time

Slot. Many Destination TS may share one Source TS.

!" Bi-direction: Normally, data is sent from the Source TS to one or more

Destination TS, which is one-way only. You can also assign a Destination TS

to be bi-directional. That is, in addition to one-way transmission, data can

be sent from the Destination TS to the Source TS. But, only the Destination

TS can be assigned to be bi-directional.

STEP 2: Select a blue time slot as the Source TS. The selected time slot (also

called source time slot) will turn pink.

STEP 3: Click the Enter TSI button to select the Destination time slots.

Figure 7-2 Time Slot Selections

STEP 3: The screen displays all effective Destination TS that can react with the

Source TS. For example, an EE&M TS is selected as Source TS. EE&M

is a voice unit, so the TSI selection screen displays all the available TS on

the voice channel units, like EE&M, EEM2, and EEM4. Those that are not

configured or are not the same type will appear gray.

STEP 4: On the screen, the Source TS appears pink, and the effective Destination

TS appears blue. Each TS is divided to two blocks: input and output.

7/29/2019 UM_FM60_A2.0

I - Input of data.O- Output of data.

The status or configuration of a TS can be verified according to itscolors.

White input and output- this TS is available for TSI configuration.

Blue input and white output- this is a destination TS that receivesdata from source TS only.

Yellow output and blue input- this is a source TS for bi-direction

transmission.

White input and gray output- this TS is already configured for TSI.

Blue input and yellow output- it means this is a destination TSused for bi-direction transmission.

White input and blue output- this is a destination TS for one way

transmission.

Table 7-2 Different States of Time Slots

STEP 5: According to the factory default, the Bi-direction function is enabled. A

bi-direction Destination TS will have blue input and yellow output. If

more than one TS is selected, the last one will have the bi-direction

function while the previous ones are one-way.

STEP 6: If bi-direction function is not required, click the bi-directional button to

disable it.

STEP 7: To de-select a selected time slot, click it again.

Chapter 8 Inband Management

The ENRS supports inband management. With an ENRS installed in the local

FM-60, other FM-60s connected to it via E1 can be configured with time slots used

for the inband management.

An EMCU-B only or an additional ENRS can remotely configure an FM-60 via

in-band or across a router. The EMCU-B supports remote configuration of up to

twenty FM-60s. An additional ENRS can manage 1024 network segments

consisted of FM-60s. A network segment may contain various FM-60s.

IMPORTANT NOTICE:

!" To configure the FM-60s via in-band connection, make sure the clocks of the

devices are synchronized.

!" In subsequent explanations and examples, where the term EMCU is used,

this means the MCU-B.

8.5 In-band Management via E1 to LAN

The FM-60 not only provides management in an E1 environment, but also in a LANenvironment. This application shows the combination of both environments. Inreal applications, the customer may utilize the E1 network to manage the devices

located in the remote LAN. This provides a flexible way for network management.

In this application, the FM-60 in the central site communicates to the FM-60A inthe remote LAN via E1. Both FM-60s must have EMCU-B and ENRS cards. FM-60A uses the LAN port of the ENRS to connect to the LAN. In the remote LAN, FM-60B and FM-60 C only need the EMCU-B, and they connect to the LAN via the LANport of the EMCU-B.

22.1 Overview

The ELAN is a channel unit of the FM-60 E1 Flexible Multiplexer. An ELAN can be

installed in any CU slot and up to three ELAN modules can be installed in one

FM-60 shelf. An ELAN is designed to provide LAN extension between networks. In

addition to bridging function, this unit also supports static routing. With the use of

the ELAN module, customers can easily establish an intra-network connecting

multiple distant locations.

Each ELAN module is equipped with one 10/100BaseT Ethernet port on its front

panel. This RJ-45 port is used to connect to the Local Area Network. Each ELAN

supports eight HDLC controllers. That is, up to eight different paths can be

established via the TSI assignment on the FM-60. Each path can be allocated its

own bandwidth (E1 time-slot) and may go to any E1 line. Each card can support a

total bandwidth of up to 32 time-slots. The destination of each path can be either

an IP address, or a sub-network with a user-defined network mask.

Chapter 23 EATU- ADSL Channel Unit

The FM60-EATU is a channel unit of the FM-60 E1 Flexible Multiplexer. This unit

has four ADSL ports for Internet access. With its concentration scheme and TSI

capability, multiple end users’ ADSL traffic can be concentrated onto any time-slot

of an E1 line to increase the bandwidth utilization. At the ISP side, the only

requirement is an unchannelized E1 router/bridge, such as CT-591, to terminate

the traffic.

The FM60-EATU is equipped with two Ethernet LAN ports, which enable for

cascading with other EATU units to accommodate more ADSL services over an E1

line. It also enables interfacing capability with an external router/bridge to allow

for more advanced functions.

With the EATU channel unit, the FM-60 can be enhanced as an integrated access

platform providing not only a leased line, but also ADSL services.

There are two different types of EATU:

!" Master: Besides the ADSL circuits, this card type can support TSI capability to

concentrate ADSL traffic onto an E1 line.

!" Slave: Provides ADSL circuits only. It has to work with a Master unit to

concentrate its traffic onto an E1 line.

this, connect to a PC via the UP LAN port.

!" The LOS LEDs (P1-P4) will only work after the port link is established. If the

port link doesn’t successfully train with the remote CPE, the LOS LEDs won’t

be operational.

23.4 Cascading EATUs

A master EATU accommodates up to three slave units, and their slot positionshould follow these rules.

!" The slave EATUs can only be installed in slots higher than the master EATU.

For example, there are two slot numbers for a master unit and a slave unit:

3, and 4. Slot 3 is the slot number to reside the master EATU.

7/29/2019 UM_FM60_A2.0


221

!" The slave units must reside in the subsequent three slots next to the master

unit. Any of the three slots can be used for the slave units.

23.5 Configuration

The EATU Configuration page covers two working panels: Common Configuration

and Port Configuration.

Figure 23-4 EATU Configuration

7/29/2019 UM_FM60_A2.0


222

Common Configuration: displays the information about the software version

and status, and it can be used to configure the card’s common settings. The Set

CU button is used to apply the common settings. The Delete CU button is used

to de-configure the card common settings.

Each field is explained below:

!" Nx64K: This field is used to set up the E1 bandwidth [N= 1-31].

!" Link Protocol: [PPP and HDLC]. This field is used to set up the session link

protocol.

!" Keep Alive (0-255 seconds):

This field is used to set the time interval at which the Keep-Alive message will be

sent. The value ranges from 0 to 255 seconds. Zero (0) means no Keep-Alive

message will be sent. In HDLC mode, the Keep-Alive message is sent to inform

the remote end that the port is ready. Upon receiving the Keep-Alive message,

the remote end should return an acknowledgement packet. The session will then

be established. In PPP mode, the Keep-Alive message is sent at regular intervals

to inform the remote end that the port is operational.

!" Authen. Method:

In PPP mode, if authentication is required, you can select an Authentication

Method (CHAP or PAP) in the [PPP Authen. Method] field, and fill in the [PPP

Authen. Method] and [PPP Authen. Password] fields. If authentication is not

required, select None in the [PPP Authen. Method] field.

!" PPP Authen. User Name/ PPP Authen. Password:

It is necessary to fill in these two fields when an authentication method (CHAP or

PAP) is selected.

Port Configuration: displays the status of the ports and the slave units that are

connected to the master, and configures the port settings. The port settings

include Detection of Loss of Signal, and Upstream and downstream data rates. If

LOS is enabled, an alarm will be declared if a LOS is detected. The Set button is

used to submit the port settings. The Deconfig button is used to deconfigure

the settings of the port. The Deconfig All button is used to deconfigure all the

ports.

Appendix E: Frequently Asked Questions

Q1. Unable to access the FM-60 via the CID software over PPP

STEP 1: Check the session baud rate.

Make sure both your modem and the FM-60 are set to the same rate. The factory

default setting of the FM-60 is 38.4 Kbps. You can modify the rate to 19.2 Kbps

via the CID.

STEP 2: Check the IP address of the CID port.

The default setting of the CID port IP address is 192.168.1.10. If it was changes,

use the new IP address to log on.

The following is an example on using the default IP address to access the FM-60.

STEP 3: Make sure you have reset FM-60 after changing the baud rate of the CID

port.

STEP 4: You must manually assign an IP to your PC that runs the CID software,

and make sure it is set to the same network segment as the FM-60 CID

port (the default IP of FM-60’s CID port is 192.168.1.10). The following

is an example on how to modify your TCP/IP for the PPP session on
