Chapter 1. Introduction
1.1 General
Thank you for choosing the Platform Fiber Multiplexer. If you would like to skip right to
the installation and configuration of the Multiplexer, proceed to Chapters 3 and 4.
The Fiber Multiplexer is a 1U (1.75") high standalone or 19/23" rack mountable
E1/T1/Data/LAN Bridge multiplexer over fiber link, built upon a highly flexible, modular design.
The Fiber Multiplexer provides an economic optical connection solution in high-density E1
and/or T1 installations such as between branch offices, where multiple high speed synchronous data
communications are required or to link a mix of platforms over a single fiber pair. By utilizing a
modular design, a large variety of configurations may be realized and the unit may be easily custom
tailored for each specific application when ordered. The 4-CHANNEL E1, T1, V.35 (X.21/RS530/RS-449) data, Ethernet Bridge Port cards and optical interface cards are all optional. The
standard unit is a chassis with local control and ordered with single or dual power. The appropriate
hot swappable optical interface cards may be selected to support multi-mode or single-mode fiber
cable operation, with a variety of transceiver power and connector options including ST™, SC, FC,
LC, or MT-RJ. WDM (Wave Division Multiplexing) optical interfaces 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).
External Clock Card (external or internal clock source) and SNMP Card (for local and remote
management purposes) may be optionally installed in the chassis.
1.2 Functional Description
The Fiber Multiplexer basic chassis is available in five power supply configurations.
Depending on the model, power may be derived from single AC 90~250VAC, single DC
+20~60VDC, dual AC 90~250VAC, dual DC +20~60VDC, or AC plus DC power sources. The
Fiber Multiplexer provides all Line Card connections on the rear panel. There are 4 slots
available for installation of 4-CHANNEL E1 or T1 Port Cards (ITU-T G.703 E1/T1), 4CHANNEL Data Port Cards (RS-530, X.21, RS-449, V.35, or RS-232), or Single-CHANNEL
Ethernet Bridge LAN Port Cards (10/100Base-TX) into the Fiber Multiplexer chassis. Each 4CHANNEL Port Card provides 4 individual channels of E1, T1, or Datacom per Port Card. The
Single-CHANNEL Ethernet Bridge LAN Port Card provides one 8.192Mb/s (4xE1 speed)
WAN link for 10/100Base Ethernet LAN bridging applications.
The 4-CHANNEL E1 Port Card has the option of using BNC (75 Ohm unbalanced) or RJ45 (120 Ohm balanced) connectors for E1 Line interface connections and supports four separate E1
channels at a transmission rate of 2.048Mb/s (transparent unframed E1) each.
The 4-CHANNEL T1 Port Card provides four RJ-45 (100 Ohm balanced) connectors for
T1(DS1) Line interface connections and supports four separate T1 (DS1) channels at a transmission
rate of 1.544Mb/s (transparent unframed T1) each.
The 4-CHANNEL Data Port Card provides four standard nx56/nx64Kb/s, up to 2.048Mb/s
for V.35 (or X.21, RS-530, RS-449, RS-232) DCE ports on MB34 (DB15, DB25, DB37, DB25)
female or male connectors (required adapter cables optional) for direct connection to terminal
equipment.
The Ethernet Bridge Port Card provides an RJ-45 connector for 10Base-T or 100Base-TX
Ethernet (auto negotiation) connections. The bridging function provides LAN to LAN segment
links which operate under the same network address space.
LEDs on the front panel will show both the channel statuses and any alarm indications for
installed port cards (except Ethernet card which display link status on the card itself).

Version 1.2 Apr 2006
Chapter 1. Introduction
The Fiber Multiplexer E1 and T1 Interface Cards fully meet all E1 and T1 specifications
including ITU-T G.703, G.704, G.732, G.733, G.823 and G.824. The Bridge Interface Card meets
all Ethernet specifications for IEEE802.3 and IEEE802.3u.
Each 4-CHANNEL Port Card features diagnostic capabilities for performing local loop
back or remote loop back (except for Ethernet Bridge card). The loop back function is controlled by
the front panel LCD menu, terminal mode (RS-232 console) or when the SNMP option board is
installed via Telnet or SNMP set commands.
Up to five clock source selections are provided. Without the external clock card option, the
unit operates from an internal free running oscillator. When the external clock card option is
installed, additional clock sources may be selected from the clock card's own internal oscillator or
from an external clock references for E1 PCM, E1 TTL, T1 PCM, or T1 TTL. All E1 and T1
equipment may connect to the Fiber Multiplexer without regard to master or slave timing. The
Fiber Multiplexer is completely transparent to clocking and data transmission. This makes
configuration of the MUX extremely easy.
The Fiber Multiplexer provides optical interfaces (1+1) that are completely redundant and hot
swappable. By utilizing a modular design, fiber type (single mode or multi mode), the optical power
margin requirement and connector type can be easily chosen at installation time. This provides an
extremely flexible main unit which is not tied to a fixed optical interface. When two optical
modules are installed, the secondary module is in "standby", in case of any failure in the primary
path. If the primary fiber path fails, the switchover time to the secondary fiber is less than 50
milliseconds (industry standard). The automatic fall over function of the fiber allows the fiber to
continue to run in the secondary fiber, even after primary fiber connection is restored. This will
avoid another 50 millisecond loss of transmission on all channels. The fiber path can also be forced
from primary to secondary or back through the LCD menu or terminal console.
When the Fiber Multiplexer is ordered with an optional SNMP Card, the card is installed
inside the chassis. Configuration is accomplished via local control on 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. The Fiber Multiplexer also has a Windows™ based GUI
management program that communicates with the Fiber Multiplexer via SNMP protocol to
display all status in real time, configure the unit, provides performance monitoring, and display
alarm buffers and real time trap messages. If the SNMP Card option is not installed, local and
remote management is still possible via the unit's internal menu system accessible from the front
panel LCD and menu keys, or via the asynchronous RS-232 port with a standard VT-100 terminal.
The Fiber Multiplexer 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.

Chapter 1. Introduction
1.4 E1 Signal Structure
E1 link line rate
The E1 line operates at a nominal rate of 2.048Mb/s.
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.
The 4-CHANNEL E1 Port Card supports two E1 line codes:
AMI coding.
HDB3 coding.
The 4-CHANNEL E1 Port Card supports only transparent unframed format. ie. The E1 will
pass through with its original framing structure completely intact.
1.5 T1(DS1) Signal Structure
T1 link line rate
The T1 line operates at a nominal rate of 1.544Mb/s.
T1 link line coding
The basic T1 line signal is coded using either the Alternate Mark Inversion (AMI) or B8ZS
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 1.544Mb/s transmissions
because synchronization loss occurs during long strings of data zeros.
In the B8ZS format, a string of eight consecutive zeros is replaced with a substitute string of
pulses containing an intentional bipolar violation. The B8ZS code substitutions provide high pulse
density so that the receiving equipment is able to maintain synchronization with the received signal.
The 4-CHANNEL T1 Port Card supports two T1 line codes:

Chapter 1. Introduction
1.6 Applications / Capabilities
In the following example, the Fiber Multiplexer utilizes an optical fiber connection between
a pair of units to provide 4, 8, 12 or 16 channels of E1, T1, Datacom, or 1 to 4 channels of Ethernet
Bridge between the units.
The timing scheme for typical E1 or T1 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 16 available
channels of the Fiber Multiplexer is independent of any other channel for framing or timing. For
datacom channels (V.35, X.21, etc.) full timing configuration is possible to either provide clock,
receive clock or to transparently pass clock from one device to the other.

2.1 Introduction
This chapter provides a more descriptive over-view of the available 4-Channel Port card
options. Detailed specifications are in Chapter 1, while removal and replacement procedures are
detailed in Chapter 3. Unit configuration is all covered in Chapter 4. The cards are NOT designed to
be "hot" swappable, therefore make sure the Fiber Multiplexer chassis is powered off before
replacing a card or pulling it from the chassis. Removal and installation of 4-Channel Port Cards
with the rack chassis under power is NOT RECOMMENDED and will definitely effect the
operation of the other 4-Channel Port Cards (insertion and removal cannot be recognized by the
Fiber Multiplexer ).
2.2 Port Card Overview
The 4-Channel Port Cards for the Fiber Multiplexer are modular PCAs which slide into
the Fiber Multiplexer chassis, and interface with the internal "main board". The main board
provides an interface connection to the 4-Channel Port Cards for power, data connection and
other logic (for local management terminal and optional SNMP).
2.3 4 x E1 I/F Module Overview
The 4 x E1 4-Channel Port Cards for the Fiber Multiplexer are modular PCAs which slide
into the Fiber Multiplexer chassis and provide four completely independent ITU-T G.703 E1
interfaces. The PCA module terminates with a DB25F connector that is designed to connect to a
physical adapter. The adapter is available in two options, one, with 4 pairs of BNC connectors for
75 Ohm unbalanced connections and the other with four RJ-45 jacks for 120 Ohm balanced
connections.
2.4 4 x T1 I/F Module Overview
The 4 x T1 4-Channel Port Cards for the Fiber Multiplexer are modular PCAs which slide
into the Fiber Multiplexer chassis and provide four completely independent T1(DS1) interfaces.
The PCA module terminates with a DB25F connector that is designed to connect to a physical
adapter. The adapter is available with four RJ-45 jacks for 100 Ohm balanced connections.
2.5 External Clock Overview
The Fiber Multiplexer is available with an external clock option that allows the unit to be
synchronized with external clocks or equipment. The Fiber Multiplexer may receive an external
clock source from E1 PCM, E1 TTL, T1 PCM or T1 TTL signal sources. Additionally, the option
includes its own precision crystal based clock. The external clock is received via an RJ-45 jack
from the rear panel.

2.6 4 x Data I/F Module Overview
The 4 x Data 4-Channel Port Cards for the Fiber Multiplexer are modular PCAs which slide
into the Fiber Multiplexer chassis and provide four completely independent Data (V.35, X.21,
RS-530, RS-449, or RS-232) interfaces. The PCA module terminates with a HD62F connector that
is designed to connect to a physical adapter. The Data module is available in one of ten interface
and cable options.

Filter:
When this feature is disabled (DIP1-1 OFF), all frames are passed transparently. In this
configuration, the ET100 acts as an Ethernet repeater. When the filter is enabled (DIP-1 ON),
frame destinations are tested against the internal MAC address table. Filtering enabled is the normal
selection for Bridging. When operating with modern switching HUB equipment, there is no need to
enable the filtering function as the switching HUB will do the necessary filtering. In repeater mode,
the small MAC address table (256) is not required and the unit can function in a large network
without regard to MAC filtering. The module is set to repeater mode from the factory.
Auto Negotiation:
When this feature is enabled (DIP1-3 OFF), the LAN Duplex (DIP1-4) and Speed (DIP1-5)
settings are ignored. In this default setting, the bridge will try to determine the proper speed and
duplex mode of the connected device. This is the preferred method of configuration, and does not
require the specific knowledge of the capabilities of the device to which the bridge is connected.
For legacy equipment that does not support auto-negotiation, it is highly recommended to place
DIP1-3 in the ON position and manually adjust the LAN duplex (DIP1-4) and speed (DIP1-5)
configuration settings. Failure to make the proper Ethernet settings can result in reduced LAN
performance or in worst case, no LAN function at all.

Version 1.2 Apr 2006
Chapter 2. Port Card Overview
Duplex:
The original specifications for Ethernet did not allow any bi-directional transmissions. The
Ethernet operated in a half duplex mode. Modern Ethernet has the ability to operate in Full duplex
mode which essentially doubles the throughput from 10Mbps to 20Mbps on 10Base-T or from
100Mbps to 200Mbps on 100Base-TX. Using this setting requires connection to equipment which
also supports Full duplex Ethernet. Setting DIP1-4 OFF will enable this Full duplex mode.
However, if Auto-negotiation is enabled (DIP1-3 OFF), then this switch's setting is ignored.
Speed:
DIP1-5 is used to set the Ethernet speed at 10Mbps (10Base-T) or 100Mbps (100Base-TX).
When set ON, the Ethernet connection will operate in the slower 10Base-T speed. When DIP1-5 is
set OFF, the Ethernet connection will operate at 100Base-TX speed. However, if Auto-negotiation
is enabled (DIP1-3 OFF), then this switch's setting is ignored.
Auto MDI:
Auto MDI is a new Ethernet feature which allows Ethernet connections between MDI
devices and/or MDI-X devices (HUBs) all using only straight thru, one-to-one, UTP connections.
When DIP1-6 is ON, this feature is enabled. When this feature is disabled (DIP1-6 OFF), the device
becomes MDI only and requires a crossover UTP cable to connect to another MDI device (such as
PCs). Straight cable connections are used for connecting to MDI-X devices such as HUBs.

Chapter 3. Installation
3.1 General
This chapter explains in detail the requirements and procedures for the installation of the
Fiber Multiplexer Standalone/Rack Mount Fiber Optical Multiplexer.
3.2 Site Preparation
Install the Fiber Multiplexer within reach of an easily accessible grounded AC outlet. The
outlet should be capable of furnishing 90 to 250 VAC (20 to 60 VDC for DC supply). Allow at least
10cm (4 inch) clearance at the rear and front of the Fiber Multiplexer for signal lines and
interface cables.
3.3 Mechanical Assembly
The Fiber Multiplexer is designed for rack mount installation and only requires 1U space (1
3/4") in a standard EIA 19 or 23 inch rack. It is highly recommended that the unit be placed in a
rack. The Fiber Multiplexer may or may not be delivered completely assembled. No provision is
made for bolting the Fiber Multiplexer to a tabletop.

Chapter 3. Installation
3.4 Electrical Installation
3.4.1 Power connection
For a model with AC power supply, AC power (90~250VAC) is supplied to the Fiber
Multiplexer through a standard IEC 3-prong receptacle, located on the rear of the chassis. For a
model with DC power supply, DC –48V (20~60VDC) is connected to the terminal block, observing
the proper polarity. In the AC/DC model, both IEC receptacle and DC terminal block are provided
for dual power operation. The Fiber Multiplexer should always be grounded through the
protective earth lead of the power cable in AC installations, or via the frame ground connection for
DC installations.

3.5 Removal/Replacement Procedures
3.5.1 Optical Module Removal / Replacement (Hot Swappable)
The optical interfaces are installed into the front of the Fiber Multiplexer. The front plane
connectors of the internal mainboard provide both DC power to the optical interface cards and
routes signals from the cards to the multiplexing/de-multiplexing circuitry. Two separate modular
interfaces are provided for connection to the primary optical transmit and receive pair and to the
redundant optical transmit and receive pair (if the redundant optical interface module is installed).
From here, the de-multiplexed signals are sent to the individual 4-CHANNEL Card module/channel
installed in the rear of the unit (see 3-5-2 for removal/replacement procedures).
To remove either interface module, loosen the captive thumb screws until the threads are
disengaged from the chassis. Gently pull the card straight forward by the captive screws using equal
force to avoid binding. The card is only held by the friction of the connector. To install an optical
module, reverse the procedure, taking care when seating the module to avoid connector damage.
Gently, don't force it! Re-tighten the captive screws but don't over-tighten.
Remove fiber cables
Loosen the captive screws.
Pull out the module by the captive screws.
Reverse the procedure with replacement.

3.5.2 Channel Port I/F Module Removal / Replacement
****CAUTION**** All the following removal/replacement procedures must be done with
all power sources disconnected.
All 4-Channel Port Cards install into the rear of the Fiber Multiplexer. The channel
connector for E1/T1 is held by two "thumb" screws. Loosen both thumb screws (use a flat blade
screwdriver if they are too tight), then remove the connector adapter by gently pulling straight back.
The 4-Channel Port cards are held in by three small flathead screws. Using a No.2 Philips
screwdriver, remove the two upper and one lower screw, then pull the module straight out (refer to
the pictures below). To install the 4-Channel Port module, reverse the procedure, taking care when
seating the module to avoid connector damage. Gently seat it, do not force it! Re-install the three
flathead screws and do not over-tighten. Then re-install the appropriate channel adapter and tighten
the thumb screws gradually and evenly. Tightening lightly with screwdriver if by hand is
insufficient.

3.5.3 Top cover Removal / Replacement for internal access
Normally, there is no need to remove the cover of the unit. All interface cards can be removed
and replaced without the need to access the internal portion of the Fiber Multiplexer. However, to
change any AC or DC power module, add the SNMP and/or External clock feature, or to change the
internal firmware, internal access is required and the cover must be removed.
***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.
1. If the unit is installed in a rack, it must be removed.
2. The rack mounting brackets, if installed, must both be removed.
3. Follow the procedure in 3-5-2 and remove the Port No. 2 4-Channel Port module.
4. The top cover is held in place by seven screws. Remove the two upper screws on each side
of the unit.
5. From the back of the unit, remove the upper screws on the far left, far right, and center of
the unit. (The center screw is hidden unless the No.2 Port module is removed.)
6. Use your finger to push up the top panel through the open Port No.2 hole.

Chapter 4. Operation
4.3 Terminal Mode Operation
A notebook computer has become an invaluable tool of the Systems Engineer. Connection
between the computer and the Fiber Multiplexer is very straight forward. The only hardware
required is a RJ-45 to DB9F adapter cable (see below for pin out). The Fiber Multiplexer's RS232 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 Fiber Multiplexer are 19.2K baud, 8 bits,
no parity, 1 stop bit and no flow control. In the HyperTerminal program terminal window click the
"properties" icon and set the communication parameters as in the following graphics. Click the
"Configure…" button in the properties window and set the port settings. When set properly, click
"OK".
Figure 4-2 HyperTerminal port settings for Fiber Multiplexer
4.4 Connecting to the Fiber Multiplexer
The console port on the Fiber Multiplexer is an RS-232D interface (DCE) that utilizes an
RJ-45 connector. Use the configuration cable that is supplied with the Fiber Multiplexer or
prepare a three wire DB9(F) to RJ-45 cable with the following pin out:

4.5 Configuring in Console Mode
The Fiber Multiplexer Control Port (labeled RS-232 CONSOLE on the front panel) is a
console terminal port designed to facilitate setup of all parameters through the use of a standard text
based terminal or any terminal emulation program running on a Personal Computer. Make the
appropriate connections, start the terminal application, apply power to the Fiber Multiplexer, then
press ENTER on the PC keyboard. If you are using "HyperTerminal™" the display should similar

The System Status display gives an overview of the entire system, both local and remote
units, the channel conditions, optical connections, and power supply status. In the above display
note that all Port cards are installed and that all 4 channels (1A~1B) are in service (v) without any
errors from local or remote side except for Port 4 which is a LAN card (The LAN card combines
the entire port throughput into a single WAN bridge). The optical 1 (O1) connection is working (W)
and optical 2 (O2) is in standby (S) mode. Both power supplies (P1 and P2) are active in both local
and remote side units.
The display screen will refresh every 5 seconds. If there is no link to the remote unit, then no
status information will be available from the remote side, all fields will go blank, and the refresh
will take more than 20 seconds.
Another important diagnostic display of the Fiber Multiplexer is the Alarm Buffer display.
Note that it is item three on the root menu. If we press "3" the Alarm Buffer will display.

The Alarm Buffer can be cleared by pressing the "c" key. Note that each entry in the buffer is
"time stamped" with the actual time of occurrence (based on real time clock setting). So it is
important to properly set the Date & Time as described previously.
4.5.11 Performance Display
Another important diagnostic display is the Performance Monitor display. This display is also
accessible from the root menu, as item "4". The display looks similar to the following.

The performance data for all 16 channels is shown, 4 for each of 4 ports, plus the optical
performance. There is a total of 96 history pages, 00~95 with 00 being the current performance
display. Each performance history represents a 15 minute interval (900 seconds), while all 96
history intervals represent the last 24 hours. To view a previous performance history interval, press
the <ENTER> key and enter the two digit interval ie. enter with the leading zero, 01, 02, 03, etc.
There are four (4) intervals per hour, so if we wanted to view the history interval three hours ago,
enter interval 12.
To clear all the data in the history intervals, use the "R" key.
4.5.12 Alarm Cut Off
The very last item on the root menu is the Alarm Cut Off function. To turn off an activated
audible or visual alarm, the ACU pushbutton on the front of the unit may be pushed or in terminal
mode, the alarm may be cut off for the local or remote unit. Press item "5" from the root menu. The
"Audible Alarm Cut-off" LED will light on the front panel to indicate ACO.
This completes the overview of the LCD and Console mode configuration and status

Chapter 6. SNMP Operation
6.1 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 Fiber Multiplexer 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 SNMPbased network management station. Only the addressed managed entity (agent) answers the polling
of the management station (except for trap messages).
6.2 SNMP Operations
The SNMP protocol includes four types of operations:
getRequest
getNextRequest
setRequest
trap
Command for retrieving specific value of an "instance"
from the managed node. The managed node responds
with a getResponse message.
Command for retrieving sequentially specific
management information from the managed node.
The managed node responds with a getResponse
message.
Command for manipulating the value of an "instance"
within the managed node. The managed node responds
with a getResponse message.
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.
47
Version 1.2 Apr 2006
Chapter 6. SNMP Operation
6.3 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.
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
Read-write
Write-only
Not accessible
Instances of an object can be read, but cannot be set.
Instances of an object can be read or set.
Instances of an object can be set, but cannot be read.
Instances of an object cannot be read, nor set.
6.4 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.
48
Version 1.2 Apr 2006
Chapter 6. SNMP Operation
Enterprise-specific MIB's are published and distributed by their creators, who are responsible
for their contents.
The MIB supported by the Fiber Multiplexer SNMP Agent follows RFC 1158 (MIB-II
standard).
6.5 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).
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.
6.6 Configuring the SNMP Agent
The agent for the Fiber Multiplexer resides in the SNMP option card installed in the Fiber
Multiplexer. Configuration of the agent is accomplished via the RS-232 Control Port of the Fiber
Multiplexer. From the Define System Parameter menu select "9", SNMP Agent.

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 Fiber Multiplexer is to be managed from a different subnet.
Item number 4, is the IP address of a server running the TFTP protocol (trivial FTP) used for
updating the SNMP firmware image in the SNMP card.
Item number 5, is the path and filename of the image file that the SNMP card will download when
the TFTP upgrade function is called.
After setting, exit the Agent configuration menu with <ESC> and the save the settings by
selecting item "4" from the SNMP Card Config menu or continue to Manager Config.
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.
Remember, when setting the "server path" information for a UNIX or LINUX based server,
the upper and lower case must be correctly observed. Also remember that UNIX path separators use
"/" while Windows uses "\" to separate path directories.

From the SNMP Card Config menu, select item "2", Manager Config. 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 Fiber Multiplexer).

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 Fiber Multiplexer.
Note that in the above example, the management workstation with IP address 172.24.1.126
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, <ESC> to the
SNMP Card Config menu and do "Save and Restart".
