Opticial amplifiers - Part 6-1: Interfaces - Command set (IEC 61291-6-1:2008)
This part of IEC 61291 describes the optical amplifier command set (OACS) for use in communicating with and controlling intelligent optical amplifiers. These amplifiers can receive and possibly respond to such commands by using resident firmware or may be optical amplifiers controlled by a microprocessor. This standard addresses the structure and content of the command set to control optical amplifiers. It does not cover the physical or hardware interface, which is assumed to exist for communication of this command set to the optical amplifier. The specification of a physical interface will be the subject of a separate Part to be developed in the IEC 61291-6 series. The command set described in this standard is intended to enable a user or host to retrieve the amplifier module's status and/or adjust its settings. This standard lists all of the commands currently defined and supported within the OACS framework. The commands described cover a wide range of applications, and not all commands will be applicable to every amplifier. To determine the supported commands on an OACS compliant amplifier, please refer to the product specification supplied by the manufacturer. All OACS compliant amplifiers support the full set of "universal" OACS commands. Other commands, usually specific to a design or implementation, may support some or all of the "optional" commands.

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61291-6-1 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: CDV Report on voting 86C/803/CDV 86C/845/RVC
Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61291 series, published under the general title Optical amplifiers can be found on the IEC website. SIST EN 61291-6-1:2008

SIST EN 61291-6-1:2008
61291-6-1 © IEC:2008 – 5 – INTRODUCTION Optical amplifiers are being developed and commercially deployed with an increasing degree of sophistication and functionality. Often, information is sent to the optical amplifier, or requested from it, in order to determine signal conditions, operating parameters, and to adjust the operational aspects of the optical amplifier. Currently, no International Standard exists in this area, yet the need for a common set of command statements to/from optical amplifiers has emerged.
This part of IEC 61291 proposes a set of command strings useful in controlling optical amplifiers. It is based on an existing set of commands widely used across the industry today. The standardization of this command set will result in broader market use of advanced designs of optical amplifiers, typically controlled by microprocessors. These advanced amplifier designs are needed for next generation optical networks, requiring adaptive provisioning of optical paths and intelligent configuration/reconfiguration for provision of telecommunications services in a dynamic environment.
This standard addresses the structure and content of the command set to control optical amplifiers. It does not cover the physical or hardware interface which is assumed to exist for communication of this command set to the optical amplifier. The specification of a physical interface will be the subject of a separate standard yet to be developed.
With the rapidly evolving technology, it is envisioned that this standard will be amended with additional commands and functionality as technology evolves, and will be updated on a periodic basis, incorporating all previous amendments and additions.

61291-6-1 © IEC:2008 – 7 – 4 General rules and concepts 4.1 Command set encoding language All data sent to/from the module are encoded in 8-bit ASCII characters. Refer to ISO/IEC 8859-1.
4.2 Module initiated commands The optical amplifier never sends an unsolicited response. Asynchronous notifications may be made, for example, by raising the appropriate “alarm” output hardware signal. However, the module may be configurable to send a prompt on power-on reset. This initial prompt may be preceded by one or more start-up messages. 4.3 Command set syntax structure Commands consist of a command string, zero or more arguments, and end with a terminator. Command strings are case-insensitive. All commands have the following format: COMMAND ……… 4.4 Command arguments
Arguments may be strings of letters, integers or floating-point numbers. Floating-point numbers shall be entered in fixed notation (e.g. 0.023 not 2.3e-2). Command strings and arguments shall be separated by one or more separator characters. Separators shall be 8-bit ASCII space characters. 4.5 Command set terminators The command terminator is . In the case of , the command is executed on receipt of the character and the character is ignored. A successful command execution may be responded to with an “OK” Unacknowledged commands may be responded to with a “??”. Command response consists of an optional response or error message. Error messages always start with the “?” character and normal responses do not. If a command completes normally and has no useful information to report, its response will be empty (no characters). Contents of error messages are not specified within this standard. The following are examples of some of the types of errors that are possible (this list is not all-inclusive): ?Unknown command 'REBOOT' ?Argument ‘x’ invalid ?Argument ‘5’ out of range [1,4] ?Not implemented ?? 4.6 Module response prompt All responses are followed by a prompt, which indicates that the module is ready to process another command. The default prompt is “>”.
SIST EN 61291-6-1:2008
– 8 – 61291-6-1 © IEC:2008 4.7 Echo mode
By default, the module doesn’t echo characters sent to it. However, if echo mode is enabled, printable 8-bit ASCII characters are echoed. Also, echo mode enables command-line editing using the backspace key (the backspaces are echoed if there are characters to delete). 5 Supported commands Table 1 summarizes the software commands that are supported through the OACS interface. The description of software commands in Table 1 is normative while the commands are informative. There are two sets of commands that are currently being used in the industry. It is recommended that the user choose the commands from only one of the sets, i.e. either from set I or II, and not mix the commands from the two sets. For detailed command syntax and the corresponding response, see Clause 6 for the universal set of commands used by all OACS compliant optical amplifiers or Clause 7 for additional optional command sets.
