Chapter 1: Introduction
Chapter 1. Introduction
Thank you for choosing the QUAD FIBER T. If you would like to skip right to the
installation and configuration of the Multiplexer, proceed to Chapters 2 and 3.
This manual is used to explain the installation and operating procedures for the QUAD
FIBER T, 4 Port Fiber Optical E1/T1 Multiplexer, and present its capabilities. This
specifications manual is divided into 5 Chapters, the Introduction, Installation, Operation,
Loop Back Testing and SNMP chapters. The Appendix includes the pin assignments of
special cables and gives further information on options for placing the device in service.
The divisions of the manual are intended for use by personnel to answer questions in general
areas. Planners and potential purchasers may read the Introduction to determine the suitability
of the product to its intended use; Installers should read the Installation Chapter and the
Cabling Specification Appendix; Operating Personnel would use the Operations Chapter to
become familiar with the line cards and settings. Operating Personnel and Network
Administrators should read the chapters on loop back testing and on SNMP to become
familiar with the diagnostic capabilities, network settings and management strategies when
the optional SNMP card is installed.
1.1 General Description
The QUAD FIBER T is a 1U (1.75") high standalone or half rack mountable E1/T1 multiplexer
over fiber link designed for cost effective applications. The QUAD FIBER T provides an
economic optical connection solution in low-density E1 or T1 installations such as between
remote offices, where multiple high speed synchronous TDM (Time Division
Multiplexing) communications are required over a single fiber pair. By utilizing a fixed channel
design, the unit is extremely cost effective and provides quick return on investment.
1.2 Functional and Feature Description
The standard unit is a standalone chassis with local control (DIP switch settable or via
Console port) and ordered with either AC or DC power. The appropriate optical transceiver
may be selected when ordering to support multi-mode or single-mode fiber cable operation,
with a variety of power and connector options including ST™, SC, FC, or LC. WDM (Wave
Division Multiplexing) optical transceivers are also available to provide bi-directional
transmission on a single fiber to reduce cost when using leased fiber links. The range of
transmission for optical connection is from 2Km (for multi-mode) up to 120Km (single
mode).
SNMP (for local and remote management purposes) and FXS Order Wire are options that
may be factory ordered or may be ordered separately for later installation in the unit. The
QUAD FIBER T is available in three power supply configurations. Depending on the model,
power may be derived from single AC 100~240VAC, single DC +18~36VDC, or
single DC +36~72VDC power source. The QUAD FIBER T provides all interface
connections on the rear panel. There are 4 channel connections for ITU-T G.703 E1/T1 on
4 x RJ-45 (USOC RJ-48C) or 8 x BNC connectors. Each Channel connector provides an
individual channel of E1 or T1, depending on the unit's configuration.
7
Chapter 1: Introduction
When configured for E1 operation, the 4 channels of the QUAD FIBER T may use either
BNC (75 Ohm unbalanced) or RJ-45 (120 Ohm balanced) connectors for E1 Line
interface connections. Each separate E1 channel supports a transmission rate of 2.048Mb/s
(transparent unframed E1) each.
When configured for T1 operation, the 4 channels of the QUAD FIBER T will use four RJ-45
(100 Ohm balanced) connectors for T1(DS1) Line interface connections. Each separate T1 (DS1)
channel supports a transmission rate of 1.544Mb/s (transparent unframed T1) each.
Three state LEDs (red, green or off) on the front panel will show both the channel statuses
and any alarm indications for the channels as well as the link status of the fiber optic link.
The QUAD FIBER T E1 and T1 Interfaces fully meet all E1 and T1 specifications including
ITU-T G.703, G.704, G.732, G.733, G.823 and G.824.
Each E1/T1-CHANNEL features diagnostic capabilities for performing local loop back,
remote loop back, or to request remote loop back. The loop back function is controlled by
front panel DIP switch setting, terminal mode (RS-232 console) or, when the SNMP option
board is installed, via Telnet or SNMP set commands.
The QUAD FIBER T unit's optical transmission operates from an internal free running oscillator.
All E1 or T1 equipment may connect to the QUAD FIBER T without regard to master or slave
timing. The QUAD FIBER T is completely transparent to clocking and data transmission.
This makesconfiguration of the MUX extremely simple. However, the QUAD FIBER T
provides no system clock or clock source for the E1 or T1 connection. Therefore, the connected
device on one side must provide the required E1 or T1 clock timing (either internal
clock or recovery timing).
When the QUAD FIBER T is ordered with optional SNMP, an additional hardware card is installed
inside the unit. Configuration is accomplished via the asynchronous RS-232 port with a
standard VT-100 terminal, via Ethernet and Telnet, or via any standard SNMP network
management software over Ethernet. If the SNMP option is not installed, local management is
still possible via the unit's internal menu system accessible from the asynchronous RS-232
port with a standard VT-100 terminal. Very basic configuration may also be done via the
front panel DIP switches, in which case the console functions are disabled.
The QUAD FIBER T also includes the ability to do in-band remote configuration. Once the fiber
optic link has been established, the remote unit may be configured or status checked from the local
unit using any of the available management options, including SNMP.
The QUAD FIBER T has the ability to upgrade its hardware and operational code by using
the Xmodem protocol on the serial interface. Local upgrades are supported with this feature.
TFTP upgrading of local or remote is supported when an optional SNMP module is installed.
8
Chapter 1: Introduction
When the QUAD FIBER T is ordered with optional Order Wire, a hardware card is installed
inside the unit. The front panel's RJ-11 jack provides a "hot line" between the two QUAD FIBER
T units in the link. Standard telephones may be connected to the RJ-11 jacks and when a phone
Is taken is ta"off hook", the remote side will automatically ring. Once answered, both parties
may talk normally. Following the conversation, both parties will place the phones back "on hook"
and the system is again ready for any direct line calls.
Included within the QUAD FIBER T system unit is integrated optical BERT (Bit Error Rate
Tester). This feature provides a built-in pattern generator and receiver. The BERT
function is designed to run "in-band" allowing BER Testing and data transmission to co-exist
on the fiber media. This allows the BERT function to be running constantly even while the
unit is in service, without effecting normal customer data transmissions. The status of the error
rate on the optical connection may then be monitored via LED indicators on the front panel
of the QUAD FIBER T.

1.6 E1 Signal Structure
1.6.1 E1 link line rate
The E1 line operates at a nominal rate of 2.048Mb/s.
1.6.2 E1 link line coding
The basic E1 line signal is coded using either the Alternate Mark Inversion (AMI) or HDB3
rule. In the AMI format, "ones" are alternately transmitted as positive and negative pulses,
whereas "zeros" are transmitted as a zero voltage level. AMI is not used in most 2.048Mb/s
transmissions because synchronization loss occurs during long strings of data zeros.
In the HDB3 format, a string of four consecutive zeros is replaced with a substitute string of
pulses containing an intentional bipolar violation. The HDB3 code substitutions provide high
pulse density so that the receiving equipment is able to maintain synchronization with the
received signal.
When configured for E1, the 4-CHANNEL E1 Ports support one of two E1 line codes:
AMI coding.
HDB3 coding.
The 4-CHANNEL E1 Ports support only transparent unframed format. ie. The E1 will pass
through with its original framing structure completely intact.

1.8 Applications / Capabilities
In the following example, the QUAD FIBER T utilizes an optical fiber connection between a
units to provide 4channels of E1 or T1 between the units. The timing scheme for typical pair of
E1 orT1 equipment is to transparently pass timing from a timing source unit on one
side, to a timing slaved unit on the other. Each of the up to 4 available channels of the
QUAD FIBER T is independent of any other channel for transparent framing or timing.

2.5 Electrical Installation
2.5.1 Power connection, AC
For a model with AC power supply, AC power (100~240VAC) is supplied to the QUAD
FIBER T through a becoming standard clover leaf 3-prong receptacle, located on the rear of
the unit. The QUAD FIBER T should always be grounded through the protective earth lead
of the power cable in AC installations.
AC Input
2.5.2 Power connection, DC
For a model with DC power supply, DC -24V (18~36VDC) or DC -48V (36~72VDC) is
connected to the detachable terminal block. The DC power connector uses a 'Molex' type
connector with detachable terminal block. Please take extra caution to observe the proper
polarity of the DC when wiring the connector. The QUAD FIBER T should always be
grounded through the protective earth lead via the frame ground connection for DC installations.

2.8 Removal/Replacement Procedures
2.8.1 Order Wire Feature Module Removal / Replacement
***CAUTION***
This procedure should only be performed by qualified service personnel. In addition, all
power connections must be removed before attempting to open the case.
The Order Wire feature is installed as separate daughter cards inside the pair of QUAD FIBER
T. The front panel RJ-11 telephone connector routes to the OW (Order Wire) interface PCB. The
OW option provides a standard FXS connection that links to the remote QUAD FIBER T unit via
the fiber optical interface. Calls are placed simply by lifting the telephone off-hook. The remote
telephone will ring.
To install or remove the OW option;
1. Loosen the captive thumb screws on the rear of the QUAD FIBER T until the threads
are disengaged from the housing.
2. Gently pull the PCB assembly straight out the rear of the housing. Remove the Order Wire
module PCBA from it's protective wrapping. Refer to the graphic on page 10 for the location
of the Order Wire option.
3. Align the connector pins as in the following photos, seat the module, insert the two

3.3 Terminal Mode Operation
A notebook computer has become an invaluable tool of the Systems Engineer. Connection
between the computer and the QUAD FIBER T is very straight forward. The only hardware
required is a DB9M to DB9F adapter cable (see pinout below). The QUAD FIBER T's
RS-232 Console port acts as a DCE to the PC's DTE communications port. A convenient
application, provided with the Microsoft Windows® 98/NT/2K/XP operating systems, is
"HyperTerminal™". The settings for console port communication with the QUAD FIBER T are
1 stop bit and no flow control. In the HyperTerminal program 19.2K baud, 8 bits, no parity,
"properties" icon and set the communication parameters as in the terminal window click the
following graphics. Clickthe "Configure…" button in the properties window and set the
port settings. When set properly, click "OK".

2. Upgrade the FPGA Firmware
Press <ESC> to previous menu.
Note: No upgrade feature is available when logged into the REMOTE unit.
The 'Mainboard Firmware' is the operational program that controls the user interface (the
console mode), reads the DIP switch if console mode is disabled, and controls the operation
of the QUAD FIBER T. The 'FPGA Firmware' is the code that loads into the field
programmable gate array at startup. The FPGA is the physical heart of the QUAD FIBER T, it
provides the logic for the multiplexing of the E1/T1 signals, controls the loop back functions,
provides the optical scrambling and integrated BERT among many other things. The QUAD
FIBER T has the ability to upgrade the hardware and working firmware via the serial console
connection utilizing the Xmodem serial transfer protocol. If we ever find bugs or
wish to add operational improvements to the QUAD FIBER T, then we have the ability to
upgrade the units without opening or changing any firmware chips. Upgrading the FPGA
in an online unit will result in temporary loss of transmissions as the multiplexer reboots
with the new logic code however, any mainboard firmware upgrades may be
done without effecting the normal transmissions on an on-line unit.
If you are using the HyperTerminal utility provided with Windows® operating system, then
the send file function is found under the 'Transfer' pull down menu. The procedure to upgrade
the unit is to first obtain the binary code file and place it on the terminal machine, login to the
QUAD FIBER T, browse to the upgrade menu, choose the right upgrade component, confirm
your intention to do an upgrade, and then send the binary file. After the binary image
file has successfully transferred, the QUAD FIBER T will write the new firmware and reboot.

Note that the upper left hand corner of the terminal display shows "REMOTE" in inverse text.
The functions of the display and configuration are exactly the same as for the local unit with
one exception; there is no optical loop back available.
The optical path between the two multiplexers carries not only the multiplexed data from the
E1/T1 transmissions, it also carries the integrated optical BER channel, the Order Wire voice
channel, and the EOC (embedded operations channel). The EOC provides the communication
path for console and SNMP between the local and remote units. Obviously if that channel is
compromised either by loss of optical signal or by an optical loop back performed from the
remote side, the channel and remote control will be lost. Therefore, loop back of optical when
logged in to the remote is not available. If the optical link should fail while logged into the
remote unit, the terminal session will auto-logoff from the remote.
This completes the overview of the Console mode configuration and status monitoring of the
QUAD TIBER T.

Chapter 4. SNMP
Chapter 4. SNMP
4.1 General
The Simple Network Management Protocol (SNMP) is one of many protocols in the Internet
Protocol (IP) suite. SNMP is the protocol recommended specifically for the exchange of
management information between hosts residing on IP networks. Network management
allows you to monitor and control network devices remotely using conventional computer
network technology.
The SNMP management functions of the QUAD FIBER T are provided by an internal SNMP
agent, which utilizes out-of-band communication over standard 10Base-T or 100Base-TX
Ethernet. The SNMP agent is compliant with the SNMPv1 standard. SNMP communications
use the User Datagram Protocol (UDP). UDP is a connectionless transport protocol, part
of the TCP/IP suite. The SNMP application uses an asynchronous command/response
polling protocol and operates at the OSI Layer 7 (Layer 7 is the Application Layer.
Other IP applications that operate at this layer are FTP, Telnet, HTTP, SMTP, etc.). All
management traffic is initiated by the SNMP-based network management station. Only
the addressed managed entity (agent) answers the polling of the management station
(except for trap messages).
4.2 SNMP Operations
The SNMP protocol includes four types of operations:
getRequest Command for retrieving specific value of an "instance"
from the managed node. The managed node responds
with a getResponse message.
getNextRequest Command for retrieving sequentially specific
management information from the managed node.
The managed node responds with a getResponse
message.
setRequest Command for manipulating the value of an "instance"
within the managed node. The managed node responds
with a getResponse message.
trap Management message carrying unsolicited
information on extraordinary events (that is, events
which occurred not in response to a management
operation) reported by the managed node.
4.3 The Management Information Base
The management information base (MIB) includes a collection of managed objects. Managed
objects are defined as parameters that can be managed, such as specific information on device
configuring or on performance statistics values.
37
Chapter 4. SNMP
The MIB includes the definitions of relevant managed objects (MIB variables) for the specific
node. Various MIB's can be defined for various management purposes, types of equipment,
etc. The management data itself is a collection of integer, string and MIB address variables
that contain all the information necessary to manage the node.
A leaf object's definition includes the range of instances (values) and the "access" rights:
Read-only Instances of an object can be read, but cannot be set.
Read-write Instances of an object can be read or set.
Write-only Instances of an object can be set, but cannot be read.
Not accessible
Instances of an object cannot be read, nor set.
4.4 MIB Structure
The MIB has an inverted tree-like structure (root over leaves), with each definition of a
managed instance forming one leaf, located at the end of a branch of that tree. Each "leaf" in
the MIB is reached by a unique path, therefore by numbering the branching points, starting
with the top, each leaf can be uniquely defined by a sequence of numbers. The formal
description of the managed objects and the MIB structure is provided in a special
standardized format, called Abstract Syntax Notation 1, or ASN.1 (pronounced A-S-N dot
one).
Since the general collection of MIB's can also be organized in a similar structure, under the
supervision of the Internet Activities Board (IAB), any parameter included in a MIB that is
recognized by the IAB is uniquely defined.
To provide the flexibility necessary in a global structure, MIB's are classified in various
classes (branches), one of them being the experimental branch, another being the
management (mgmt) branch, and yet another the group of private (enterprise-specific) branch.
Under the private enterprise-specific branch of MIB's, each enterprise (manufacturer) can be
assigned a number, which is its enterprise number. The assigned number designates the top of
an enterprise-specific sub-tree of non-standard MIB's.
Enterprise-specific MIB's are published and distributed by their creators, who are responsible
for their contents.
The MIB supported by the QUAD FIBER T SNMP Agent follows RFC 1158 (MIB-II standard).
4.5 SNMP Communities
To enable the delimitation of management domains, SNMP uses "communities". Each
community is identified by a name, which is an alphanumeric string of up to 255 characters
defined by the user. Any SNMP entity (this term includes both managed nodes and
management stations) is assigned by its user a community name. In parallel, the user defines
for each SNMP entity a list of the communities which are authorized to communicate with it,
and the access rights associated with each community (this is the SNMP community name
table of the entity).
38
Chapter 4. SNMP
In general, SNMP agents support two types of access rights:
Read-only the SNMP agent accepts and processes only SNMP getRequest
and getNextRequest commands from management stations
which have a read-only community name.
Read-write the SNMP agent accepts and processes all the SNMP
commands received from a management station with a read-write
community name. SNMP agents are usually configured to send traps to
management stations having read-write communities.
4.6 Configuring the SNMP Agent
The agent for the QUAD FIBER T resides in the SNMP option card installed in the unit. Initial
configuration of the agent is accomplished via the RS-232 Control Port of theQUAD FIBER T.
Refer to Chapter 3, section 3.5 for operation of the console for the QUAD FIBER T and the login
procedures. From the 'Configure System Status' menu select "7", SNMP Configuration. Note:
No SNMP configuration is available when logged into the REMOTE unit.

Explanation
The SNMP agent is the process that runs in the SNMP module and has the ability to
control the QUAD FIBER T. The agent requires network configuration, ie. IP address, subnet
mask and default gateway settings.
The manager configuration provides the needed information to the agent for the network
manager on your network. This information can be assigned for up to four different
management workstations. The information set includes the IP address of the management
workstation, the access rights (read/write or read only) which are provided by the community
string, plus if the agent is to send traps (unsolicited messages) to the management
workstation.
The TFTP server is required if doing any software upgrade of the SNMP agent. The two
configuration parameters are the IP address of the TFTP server and the path to the upload file.

Press <ESC> to previous menu.
Item number 1, IP address is the IP address that the SNMP card will answer to when
"pinged", Telnet'd, TFTP'd or when accessed by SNMP.
Item number 2, is the subnet mask for the network that the card is attached to.
Item number 3, is the default gateway for the network that the card is attached to and is
required if the QUAD FIBER T is to be managed from a different subnet.
HINT: when entering IP addresses, enter without "dots" and include any leading zeros.
For example, the above IP address 172.24.1.11 would be entered as 172024001011 while
10.0.0.1 would be entered as 010000000001.
4.6.2 Manager Configuration
From the 'SNMP Configuration' menu, select item "2", Manager Configuration. Manager
configuration is required to tell the agent (the SNMP card) who has authority to access the
SNMP via "Get" commands (read) or "Set" commands (write) and where to send "trap"
messages (unsolicited messages that are usually generated by alarms in the QUAD FIBER T).

Chapter 4. SNMP
The manager configuration has the ability to setup access for up to four (4) different
management workstations. The community strings act like passwords in dealing with the
device via SNMP protocol. By changing the community strings (numbered 1 & 2) for read /
write ('secret' in this case) and read only ('public') access, and assigning a community string
to an access IP, an administrator can control access to the QUAD FIBER T.
HINT: when entering IP addresses, enter without "dots" and include any leading zeros.
For example, the above IP address 172.24.1.125 would be entered as 172024001125 while
10.0.0.1 would be entered as 010000000001.
Note that in the above example, the management workstation with IP address 172.24.1.125
and using the community string 'secret', has full read and write access and receives traps. The
management station at 192.168.0.15 has read only privileges when using the community
string 'public' and can also receive trap messages. The other two stations at Access IP 3&4
have read only access and do not receive any trap messages. After all settings have been
made, press ESC to the 'SNMP Configuration' menu and press "4" 'Save Configuration and

CTC Union provides a TFTP utility program that runs standalone in Windows® without any
installation. We recommend that you copy the program and any binary image files for upload
to your Windows® desktop for convenience sake. If you place the binary files and server
program in the same directory, there is no need to enter any path information in the SNMP
agent. This simplifies the settings considerably, just enter the binary filename in the TFTP
filename location in the SNMP agent. If you have a firewall enabled, please disable it before
running the TFTP server or doing the upgrade.
Start the CTCU TFTP Server program just before executing the upgrade on the multiplexer,.
After initiating the upgrade, the TFTP server will show the progress and completion of the
file transfer, whether successful or not.

4.7 MIB File
A MIB is a "management information base" file that allows network management software
understand how to manage the QUAD FIBER T. Management software could be expensive
packages of software such as HP OpenView® and Computer Associates Unicenter® or
inexpensive MIB browsers such as those from MG-Soft. Additionally, Linux and unix type
operationg systems also have SNMP utilities that allow utilizing the MIB file to access the
device agent with SNMP protocol. The MIB file is just a key that fits our device; you still
need the 'car' (management software running on a workstation) in order to drive.
The QUAD FIBER T with SNMP is provided with a MIB (Management Information Base)
file. The MIB supported by the QUAD FIBER T SNMP Agent follows RFC 1158 (MIB-II
standard). The formal description of the managed objects and the MIB structure is provided
in a special standardized format, called Abstract Syntax Notation 1, or ASN.1 (pronounced
A-S-N dot one).
The following graphic shows the MG-SOFT MIB Browser software, after importing and
compiling the MIB file, accessing the QUAD FIBET T and doing an 'SNMP Walk' on the
local E1 configuration OID. The query results are shown on the right screen.

management features of Telnet, SNMP and HTTP server. The HTTP server allows connection
and configuration in a graphical, point and click environment using any standard web browser.
4.8.1 Security Login
To connect to the QUAD FIBER T use the device's IP address as the URL location. For
example with our setup unit, enter http://192.168.0.253/ and Enter. A login security prompt
will display.
The default user name is admin. The password is the terminal password if it has been set, or if
no terminal password is set the default is 0000 (4 zeros).

4.9 Telnet Management
When the SNMP option is installed in the QUAD FIBER T, Telnet connection is available
for console type management. Choosing a Telnet client is important to get the proper
display Vfrom the SNMP agent. Clients that we have found work well are Telnet in command
window for Win98, WinME, WinNT and Win2000. HyperTerminal in TCP/IP mode works
well for all versions of Windows®.
Clients which we have found experience some difficulties with the agent are command mode
Telnet in WinXP, Telnet from Linux or FreeBSD and Windows packages such as Putty. In
command mode of WinXP, the terminal characters are echoed locally on screen, including
the password as it is typed. In Linux, FreeBSD, and Putty, an Enter key must be pressed after
every single keystroke, and again the characters are echoed.
When setting up HyperTerminal for Telnet, choose the connection as 'Winsock' or 'TCP/IP',
and then connect with the agent's IP address. The following page has a screen capture of
Telnet session in HyperTerminal.
