Chapter 9 TL1 Commands
9.2.2 Command Code Modifier (ccm)
9.2.2 Command Code Modifier (ccm)
The command code modifier (ccm) identifies the object of the action being applied by the verb of the
TL1 command. Some command code modifiers for the ONS 15216 EDFA2 are described in Table 9-1.
9.2.3 Access Identifier (aid)
The access identifier (aid) parameter uniquely identifies an object within the ONS 15216 EDFA2. For
the ONS 15216 EDFA2, there are four specific aids (1, EQPT, PWR-A, PWR-B) and the ALL aid, as
described in Table 9-2. All autonomous messages identify their specific aid in the message. For all
command inputs that require an aid as a mandatory parameter, the ALL aid is accepted as well as any
relevant specific aids. If the ALL aid is used in a command, the response contains the appropriate
specific aid. For the commands RTRV-ALM-EQPT and RTRV-COND-EQPT, inputting a specific aid
filters the response to information relevant to that aid.
9.2.4 Correlation Tag (ctag)
The correlation tag (ctag) is a unique tag associated with a command. If the user specifies a ctag while
entering a command, the response of that command from the ONS 15216 EDFA2 TL1 agent carries the
same ctag value. The ctag consists of no more than six alphanumeric characters.
9.3 Notation
The commands described in this document use the symbols shown in Tabl e 9-3 to describe the command
format. These symbols are derived from the Telcordia Network Maintenance: Network Element and
Transport Surveillance Messages Manual (Generic Requirements, GR-833-CORE).
