1.7 Fan and Power

Fan Alarm LED

The OTS-10 has a pluggable fan tray that includes five fans, an Alarm LED for the fans, and an Alarm LED for the power

supplies.

The OTS-10 provides a Fan Fault LED feature. This feature comprises of an LED light that stays off when the fans are

functioning normally but will turn red if the software detects any defects in a fan.

Power Alarm LED

The OTS-10 system provides two power supply modules. The monitoring system can monitor defects of the power supply

voltage and report the alarm information to the Network Management System.

The OTS-10 provides the PWR Fault LED feature. This feature comprises of an LED light that stays off when the power is

functioning normally but will turn red if the software detects any defect in association with the power supply.

Power Supply

The power supply must be stable with a voltage range as follows:

DC Power range: -48V~-55V DC 5.2A; 7A (The DC power itself has a fuse.)



AC Power range: 100/200V, 50/60Hz. 2.75/1.375A; (The AC power itself has no fuse)

DC-48V power corresponding type

Use power wires corresponding to the power distribution equipment. The recommended power wires should be AWG19

thickness or higher. Connect the equipment terminal of the power wire with the terminal panel on the back of the OTS-10.

1. Connect the power terminal of the power wire with DC power.

2. Connect the terminal indicated [0V] with DC 0V, the terminal indicated [-48V] with DC -48V, and the terminal indicated

[FG] with the ground of the setting site. It shows the power connection method of the OTS-10 (DC-48V power

corresponding types).

Figure 15 DC power

DC power connection

The DC power connection -48VDC is made in accordance with the -48V terminal lug for both power feeds.

Figure 16 DC power

Warning!

Power cables must be plugged in while there is no power running through the cables.

Note: If the power output does not stop, do not directly touch the metal parts of the OTS-10 DC power terminal or power cable terminal to prevent personal injury and damage to the system.

AC power corresponding type

When using AC power as the OTS-10 Series power source:

For power supply redundancy, two AC sources (preferably independent) are required. Each source should be capable of

supplying 100 watts per OTS-10 system. The AC power cables from the AC source attach to the AC power module that is

mounted at the rear of the OTS-10 system.



An AC circuit breaker is recommended for the AC power source. This circuit breaker should protect against excess currents

and short circuits and should adhere to national and local electrical codes.

Insert the device-side of the power cord into the OTS-10 Series AC inlet and insert the power source-side of the power cord

into the power source outlet.

Figure 17 Connecting the Power Cord

1. Insert the power cord plug firmly into the appropriate outlet.

2. Always use a grounded outlet.

3. Always connect both power cords.

Chapter 2 System Functions and Features 32


System Functions and Features

This chapter provides an overview of the OTS-10’s functions and features.

OptoSpan’s OTS-10 Functions

OptoSpan’s OTS-10 Features

2.1 System Functions

Media Converter Function

Service frame transmission between the devices’ Mux/Demux occurs when connecting the Long Haul(LH) ports of two

OTS-10 devices with a pair of single mode fibers (SMF) or dispersion shift fibers (DSF). Transmission span loss is 35dB

with EDFA (when FEC is enabled). Dispersion tolerance is ±800 ps/nm (zero chirp) or 0 to +1600 ps/nm (negative chirp

depending on what SFP/SFP+ is used).

Network Management Function

When the SNMP manager requests MIB information or settings, the device conducts the appropriate processing to fulfill the

request and sends the response data to the SNMP manager.

The SNMP managers that connect to the OTS-10 can be restricted as follows:

SNMP manager access restriction

SNMP manager IP address

If an IP address is set, all access—except from the registered SNMP manager—will be ignored.

Read-only community name

Read-write community name

Setting and updating of management information (MIB)

Using the Internet standard MIB prescribed by MIB RFC1213 (MIB II Revision 2), a user can adjust the system and

interface settings.

2



OptoSpan proprietary MIB such as the operation management MIB for displaying the status of each port can be

adjusted and set.

Using the MIB prescribed by RFC2863 (interface group MIB), the device ifXEntry can be adjusted and set.

Trap send function

The OTS-10 system can send the following traps to a manager that has been set as the trap receiver:

Cold trap on startup

Power failure and recovery status

Cooling fan failure and recovery status

Self-diagnostic test failure

SNMP authentication failure

Link Up/Down

Sending short frames (63 bytes or less) or long frames (9,217 bytes or more) with the Long-Haul (LH) port.

In-band Management function

By connecting the local equipment’s management port to a management device, the remote OTS-10 can be managed

through In-band OSC channels.

Protect Switch Function

PSW Group

channel 1 and channel 2 are PSW group, peer of channel 1 is channel 2 and vice versa




In a PSW group, one channel is a working channel while the other is a protection channel. These channels can be set up using the CLI or SNMP manager.

Configure PSW group Rule

PSW mode setting

The OTS-10 has three settings:



1. Standalone (default)

2. Working

3. Protection

The standalone mode is the default mode for the OTS-10. The OTS-10 needs to be in standalone mode prior to switching to working or protection modes.

Switch from working to protection

There are two ways to switch from the working to protection mode: one is the automatic switch and the other is the manual

switch.

Automatic switch

Must satisfy the following conditions to automatically switch:

PSW availability

Working channel generated LOS alarm in the LH port or the working/active daughter card was pulled out

Manual switch

The OTS-10 can switch from working to protection manually via command line when the PSW group is active. If the PSW

group is not active, the OTS-10 cannot switch manually.

Switch from protection to working

One method to switch from protection to working mode is via the command line, but the following conditions would need

to be met:

PSW availability

The working channel must not have an LOS alarm in the LH port

Pulling out a daughter card which is in protection/active mode, the system will automatically switch to another card.

Must satisfy the following conditions to switch from protection to working:

PSW availability

Protection/active channel generated LOS alarm in the LH port or protection/active SFP module was pulled out of the

LH port.

Working/standby channel power LH port, while LH port no LOS Alarm

Note: Unplugging an SH port SFP module or SH port LOS alarm will not lead to an automatic switch.



2.2 System Features

Performance Monitoring

Via the performance monitoring function, the OTS-10 can monitor the Long Haul (LH) and Short Haul (SH) port loss of

signal operational status items. This function also allows for users to check normal values from a MIB (OptoSpan

proprietary MIB), which monitors the performance of the system every 15 minutes and automatically generates daily logs.

Loopback Test

This device features a loopback test function implemented between the local device and the remote device to check the

status of the port connection. A loopback test is conducted by sending a test from the OTS-10 local device to the remote

device and then back to the local device. The test results are then recorded in a log. The following are different methods

one can conduct a loopback test:

Through the terminal using a serial connection with the loopback terminal command after entering configuration mode.

Through a telnet connection once a management IP address has been established.

Request the loopback test using an SNMP manager (MIB).

File Transfer

The OTS-10 features a TFTP client function, allowing it to download firmware updates, transfer logs, and upload and

download information to a server on the network.

Log Record

The OTS-10 can save log information when the reboot command is executed. A key feature of the OTS-10 is that it is

SYSLOG compatible. This feature enables logs to be sent automatically to a network-connected SYSLOG server.

Note: If the power is turned off without executing the reboot command, the log will not be saved.

NTP and Clock

Incorporating a real-time clock, the OTS-10 allows logs to be recorded at a time specified by the user. It is also NTP

compatible, allowing the use of a user-prepared server to synchronize the internal clock. The lithium battery saves the time

setting even when the power is turned off.

OSC

The main board in the OTS-10 main shelf consists of CPU and control circuit. This main board also supports in-band

capability by use of an Optical Service Channel (single OSC). With dual OSC, OTS-10 can be used in RING application.



System Access Capability

The interface types are as follow:

CWDM 10GbE optical interfaces

DWDM 10GbE optical interfaces

CWDM OC192 optical interfaces

DWDM OC192 optical interfaces

Chapter 3 Administration and Management 38


Administration and Management

The following chapter provides a detailed listing of how to manage and use the OTS-10 system through either the web

graphical user interface (GUI) or the command line interface (CLI).

Web Graphical User Interface (GUI)

Command Line Interface (CLI)

3.1 Introduction The OTS-10 has two default accounts set up. One is username “adpro” and the other is username “user”. Adpro is the

default admin account and user is the default user account. Both default accounts have no password, but a password can

be configured through the admin account.

The admin account has no restrictions when configuring the OTS-10. The user account does not have permissions to make

changes on the system but has permission to view all settings.

3.2 Web Graphical User Interface (WebGUI) The OTS-10 has a user-friendly GUI for users to configure the system. To access the web GUI the management IP address

must be configured using a serial port connection and the command line interface. Once the management IP address is

configured; the management IP address can be entered into any internet browser to access the web GUI.

To configure the OTS-10 through the GUI the account must have admin rank since user accounts only have access to view

setting. The GUI works by clicking to change a setting. Clicking on a field may either bring up a dropdown box for the user

to choose from or an empty textbox where the user must type in the information they wish to change the setting to.

Below are screenshots of each tab of the GUI when the system is running without any errors. The configuration of the

system during the screenshots is one SFP transceiver plugged into Long Haul (LH) port 1 and one SFP transceiver plugged

into Short Haul (SH) port 1.

3.3 Command Line Interface (CLI)

Following are the two methods to connect with OTS-10 series for general parameter configuration via PC:

The managed device must first be configured correctly using the serial port. When connecting through the RS-232 port,

the entire auto configuration can be completed using RS-232 protocol. Using putty, the user can connect to the device

through the serial connection and configure the system.

The second method is to connect your computer with the management port of the OTS-10, then login to the OTS-10 via

Telnet session. This second method only works when the OTS-10 management port is connected to an existing LAN and

the IP address has been configured through the serial port.

Below is a list of the main menu commands in the OTS-10. For an all-encompassing list of commands available refer to the

OTS series command line document which provides detailed explanations and examples of all commands.

Show – show various system information

Configure – configure parameters



Restore-config - Sets configurations to defaults except ip, ip mask & route.

Flush-config - Set all configurations to default

Write – write configurations/logs to memory

Upload – upload configurations/logs via TFTP, or output to display

Download – download configurations vis TFTP

Delete – delete a sub-card configuration

Ping – ping a destination ip (ctrl+c to exit)

Reboot – reboot system

System-download – download new system firmware via tftp

Version – show OS version and expansion card information

telnet – telnet to a destination ip

No – negate a command or reset to default values

Exit – logoff the system.

3.4 Helpful Tips Possible errors may arise when using the command line. If an “Ambiguous command” error appears, pressing TAB key will

show what information is needed to continue with the command. Another error may be “Invalid input detected” which simply

means the command you have entered is not a valid command.

When using the command line, it is highly recommended to consistently press the TAB key for any confusion as it will

directly state what the command is looking for or which commands are valid in the operation mode.

If the user wishes to logoff the system, they may do so using the EXIT command on the main menu.

Chapter 4 Networking Applications and Configurations 49


Networking Applications and

Configurations

The OTS-10 is a cost-effective solution specially designed for carriers or service providers who require a highly reliable network.

It supports the transport of 1G-10G Ethernet services and OC48, OC192 SONET services.

This chapter contains the following topics regarding the typical network configurations and applications of the OTS-10:

Equipment Application Advantages

Typical Deployment Configurations

Network Design with OTS-10

4.1 Application Advantages

The OTS-10 is a 1U Mini-chassis type Multi-service platform with a flexible configuration compatible with various network

applications. The OTS-10 has the following remarkable application advantages brought about by the implementation of new

technologies.

High Integration

The cabinet is 44.4mm x 440mm x 450mm (height x width x depth). The OTS-10 chassis frame weight is 7.3kg without

cards, and it is 9kg with two mini EDFA cards. With this 1U design, multiple OTS-10s can fit in the average network

equipment room.

Flexible Configuration

The OTS-10 provides 8 data traffic expansion channels. These data channels can be plugged in any combination of any

type of high speed 10 G module (OC192, and 10 GbE) or low speed multi-rate module (1 GbE, 1xFC, 2xFC, OC48) for

widespread compatibility.

Network Management

When the SNMP manager of the OTS-10 requests MIB information or settings, the device conducts the appropriate

processing to fulfill the request and sends response data to the SNMP manager. The OTS-10 contains management

information and responds to requests from the manager for retrieving information and when settings to be adjusted. SNMP

supports both V1 and V2 versions at the same time, allowing for the Client side to determine the version according to

preference.

The SNMP managers that connect to the OTS-10 can be restricted as follows:

• SNMP manager access restriction: read-only, read-write.

If an IP address is set, all access except from the registered SNMP manager will be ignored.

Read-only community name

Read-write community name

Managing via SNMP

When the SNMP manager requires reading or setting of the MIB contents the OTS-10 will transmit the response data to the

SNMP manager according to the request.

Figure 36 SNMP manager maps

• Setting and updating of management information (MIB)

OTS-10



Using the internet standard MIB prescribed by MIB RFC1213, the device can set and change system and interface settings.

OptoSpan proprietary MIB—such as the operation management MIB for displaying the status of each port— can be set and changed.

Using the MIB prescribed by RFC2863 (interface group MIB), the device can set and change ifXEntry.

• Trap sends function

The OTS-10 can send the following traps to a manager that has been set as the trap receiver.

Ring Application

General Description

The OTS-10 supports 2 types of Ring or linear protection application: single fiber bi-direction or dual fiber bi-direction. OTS-

DW-04-DBR supports dual fiber bi-direction protection, which divides 8 channels into two groups, one for WEST direction,

and the other for EAST direction. Each group can be configured as a working protection path by software. OSC channel is

set as 1510nm for DWDM application in both working and protection paths. For single fiber bi-direction, there are two

MUX/DEMUX used. OTS-DW-08-DBU supports signal fiber bi-directional protection without EDFA. For signal fiber bi-

directional protection with EDFA, OTS-DW-04-DBR should be used.

Stack Application

General Description

Not including the OSC channel, the OTS-10 can support a maximum of 8 channels. To support an application beyond 8

channels per one node, the OTS-10 can stack at least 5 mini-chassis, which means it can support at least 32 channels,

known as network management port stacking and optical wavelength stacking.

Stack of Management port

The OTS-10 features two 10M/100M management ports for network management stacking. Connecting the UP port to the

DOWN port of each stacking mini-chassis allows for a simpler, streamlined software management of each mini-chassis.

Figure 46 displays the network management stack.

When stacking the management ports, a band filter card is used. A band filter card divides all wavelengths into several sub-

bands. Every OTS-10 mini-chassis supports one sub-band. For example, for the DWDM system, five mini-chassis can be

stacked to support 100G grids allowing for the transmission 40 channels, as displayed in Figure 47. OTS-10-BF-05-D is the

5 sub-band band filter card which divides the full C-band (from CH21 to CH60) into a 5 sub-band. Every sub-band feeds

into one 1RU mini-chassis. Through this arrangement, a 5RU mini-chassis can support 400G transmission.

Advanced Management

The following chapter is an overview of additional details of the OTS-10 management.

5.1 Fault Management

Alarm surveillance involves detection and report of the related events and conditions happening in the network. An alarm is

generated automatically by each event and input signal. There are 5 severity levels of the alarms in the OTS-10. They are

Critical, Major, Minor, Information and Clear. The alarm and its level are shown through the alarm indicator on the OTS-10

sub-rack. After the alarm is sent to the network management system, the system can automatically analyze the detailed

description of the alarm and determine the probable cause to help with troubleshooting.

Alarm Hierarchy

Figure 48 Alarm Hierarchy Map

The following should be noted:

• There is no alarm hierarchy for OAMP interface.

• Wavelength Mismatch includes reading wavelength failure.

• “LC HW Failure” alarms can indicate a problem regardless of the configured state of the LC.

• Alarm hierarchy is used for reporting the highest priority failure for defects appearing at the same time and does not apply

to independent failures happening at different times.

5.2 Performance Monitoring

The OTS-10 can monitor the following operational status items: Long Haul and Short Haul port loss of signal. The

performance monitor function can also check normal values from an MIB (OptoSpan proprietary MIB). This function can

separately count in every 15 minutes and log daily.

Performance Monitoring (PM) collects the NE performance primitive data and status of the equipment by continuously

tracking system, network, and service activities to report and evaluate the performance of network and NE. The PM

parameters are derived from performance primitives associated with SDH frame formats defined in ITU-T G.707. The

performance parameters specified for Section and Path layers are included. Two tables are provided, one for SDH and the

other for the Ethernet interface.

Performance Data

The OTS-10 uses one 15-minute register and one 24-hour register for every performance parameter to save current performance data. After the sampling period, data will be saved to the history register which is composed of ninety-six 15-minute registers (one previous and fifteen recent) and seven 24-hour registers (one previous and five recent). Further, there is a register for saving the current performance value for each Ethernet performance parameter.

The card PM data information is as follows:

1GBE Card

Performance Monitoring Data contents include Loss of Signal Seconds (LOSS), Laser bias current (LBC), Optical power TX

(OPT) and Optical power RX (OPR).

Performance Data Reporting and Collection

Performance Monitoring records information every 15 minutes, with statistics gathered from the system within the first 15-

minute border. Statistic times should be real-time RTC of the system and the point of collection should be 15-minute

intervals, such as 12:00, 12:15, 12:30. Time stamps should adopt the ending time of each 15-minute period and the PM

function retains the last 96 historical statistics.



The PM function retains historical statistical data of up to 7 days prior.

5.3 Memory Backup

The OTS-10 provides multiple backup methods for data configuration. This system supports “write flash-memory” command.

Configuration data in the RAM can be backed up to FLASH database through the network management system, or CLI, to

prevent the loss of configuration in case of a power failure.

5.4 Configuration Management

The OTS-10 provides a configuration log to store all operation commands.

Equipment Configuration

The OTS-10 supports off-line card configuration and allows the operator to configure its card type and associated software.

This software can be backed up and upgraded without interrupting the services. The OTS-10 also boasts a built-in failover

mechanism. The software can roll back to the previous working version by re-load.
