For VLNC50/52/55 SONET/SDH network elements, operations interworking (OI) provides the capability to access, operate, administer, maintain, and provision remote Alcatel-Lucent NEs from any Alcatel-Lucent NE in a subnetwork or from a centralized OS. OI among the Alcatel-Lucent 2000, WaveStar®, Alcatel-Lucent 1850 TSS-5, and 1665 Data Multiplexer Product Families uses Target ID Address Resolution Protocol (TARP).
The following Alcatel-Lucent products support OI:
DDM-2000 OC-12 Multiplexer, R7.0 and later
DDM-2000 FiberReach Multiplexer, R3.0 and later
DDM-2000 OC-3 Multiplexer, R13.0 and later
FT-2000 OC-48 Add/Drop-Rings Terminal, R9.1 and later
All WaveStar® Product Family systems
All Alcatel-Lucent 1850 Transport Service Switch Product Family systems
All Alcatel-Lucent 1665 Data Multiplexer Product Family systems
The Alcatel-Lucent OI is available among NEs that are connected through the SONET/SDH DCC or IAO LAN. With this feature, users can perform OAM&P activities on a centralized basis, saving travel time and money.
OI features including the following:
Remote OS access via TL1 over TCP/IP
Remote login
Remote office alarms
Remote software download and copy
An alarm group is a set of SONET/SDH NEs that share status information between themselves, such as alarms, LEDs, and ACO status. The set of remote NEs that an NE can exchange status information with is determined by the value of the local alarm group parameter. This parameter is provisioned at each local NE and specifies whether that local NE does or does not exchange remote NE status with other Alcatel-Lucent NEs in the same SONET/SDH subnetwork. In Alcatel-Lucent 1850 TSS-5, all NEs are defaulted into the same alarm group (number 255).
Alarm groups can be nodes in a ring, nodes of a linear extension, or any other logical grouping such as a maintenance group or geographical group.
All members of the same alarm group share NE status information but do not share information with other alarm groups.
Note:
Only alarm information about operations managed by the VLNC2 SYSCTL, VLNC35, and VLNC50/52/55 circuit packs is shared between NEs. Information about operations managed by the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs is monitored separately.
Depending on provisioning, a member of an alarm group can:
