21、cal 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
22、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 existin
23、g 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, req
24、uiring 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 har
25、dware 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 amende
26、d with additional commands and functionality as technology evolves, and will be updated on a periodic basis, incorporating all previous amendments and additions.

27、08 OPTICAL AMPLIFIERS Part 6-1: Interfaces Command set 1 Scope 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
28、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 optic
29、al 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 modules status and/or adjust its settings. This standard
30、 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
31、 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. 2 Normative references The following referenced documents

Refer t
35、o 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
36、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 Argum
37、ents 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 s
38、et 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 option
39、al 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 fo
40、llowing 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 re
41、ady to process another command. The default prompt is “”.

However, if echo mode is enab
42、led, 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 descr
43、iption 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
44、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.
