Definitions
Card A card is defined as an individual module that can be inserted into an
OLT or ONT
Network Element A Network Element is defined as a complete OLT or ONT. A Network
Element includes all the cards provisioned in the OLT or ONT
PON A PON is defined as the fiber that connects to a PCU in an OLT. A
PON also includes all the ONTs connected to that fiber
System A System is defined as an OLT, all the cards in the OLT, all the PONs
connected to the OLT and all the ONTs connected to those PONs

Terawave Management System(TMS)
Purpose
TMS functionality includes: Provisioning Network Elements in the TMS database Provisioning hardware modules in the Network Elements Provisioning services Aggregating & displaying Alarms from Network Elements Resource aggregation – Enables viewing multiple NEs as a single unit
based upon a given set of requirements Alarm aggregation & viewing– Viewing alarms on all NEs from a
centralized platform Performance of diagnostics Setting Threshold Crossing Alert levels
TMS relies on the NE (INT, ONT or OLT) database as the database of record

Installation Requirements
TMS has hardware and software “recommendations” TMS can operate on platforms less than the minimum
recommendations, but performance and response will be less than acceptable for a standard working environment
TMS is NOT supported on the Linux OS at this time The underlying TMS code is the same as Unix, but the scripting for
installation, startup and shutdown must be written for the Linux OS

Alarm Management
Alarm management is performed on a System basis, administered by the OLT
Alarm management consists of two functions Alarm Reporting – What NMS workstations do you want information
reported to. IP address dependent
• Will report Alarms to 3 workstations
• TMS automatically uses one IP address Alarm Filtering – Severity of Alarms and what you want to do with the
Alarms
• Severity – Critical, Major, Minor, Informational
• Filter
– Ignore them
– Keep them local
– Report them to NMS workstations

Alarm Logs TMS
• Network - Includes alarms/events from all Systems
– Active
– History
– Events
– TCA events
• Alarms/Events are stored in the TMS computer RAM. A computer restart or power failure will wipe out all Alarms and Events from TMS
• After a TMS restart, Active Alarms will be retrieved through the Synchronization process
• Short term Alarms/Events are stored in tomcat/webapps/EyeWave/db

Ability exists to “synchronize” the TMS configuration databases with the NE databases
“Synchronize” can be performed on multiple levels Network Element System
An Auto-Synchronize is performed by TMS with each NE once a day (around midnight)

TMS
“Keep-Alive” Signals
Periodic Keep-Alive Every two minutes a keep alive SNMP request message is sent from
the TMS to a NE that is provisioned in TMS The NE is expected to respond to the message. If no response is
received, 3 retries are done over a 7 second period. If all requests fail, then the lightning bolt is displayed
Normal Operation During normal user operation, if any SNMP request fails, 3 retries are
done over a 7 second period. If all requests fail, then the dagger would go through the NE
