66 Strata CTX General Description 11/02
Centralized Attendant
One attendant can serve an entire Strata Net. Station users only need to dial “0” to reach the
centralized attendant regardless of the node in which they reside. The attendant can reach any
station in the network using its Network Directory Number. Trunks attached to any network node
can be programmed to terminate to the centralized attendant and their source and calling party
information will be delivered to the attendant’s display.
Centralized Voice Mail
A voice mail system attached to any Strata Net network node can serve users throughout the
enterprise. Unanswered calls will be forwarded to the voice mail, the source and calling conditions
identified and the appropriate voice mailbox greeting will be played. The voice mail system can
control message waiting indications throughout the network as messages are left and retrieved. A
single network can even support multiple centralized voice mail systems with each station being
programmed for the appropriate system.
Network SMDR
An external Strata Net call will generate a call record at the terminating node for that call. Transit
nodes will not generate records. The records can be stored in customer-supplied external buffers at
each node. Polling call accounting software can gather and organize the data from multiple nodes.
Local buffering provides survivability in the event of network disruption.
System Fault Finding and Diagnostics
The Strata CTX can detect problems in the system. These conditions can be detected, alerted,
logged, and traced. Strata CTX includes many useful diagnostic tools.
Alarm Indication of System Faults
Visual Alarms are presented to CTX WinAdmin and attendant consoles.
SmartMedia Card
This is a small memory card that is commercially available in retail stores. It is the same as
SmartMedia cards used in digital cameras, MP3 players, etc.
The Strata CTX uses the SmartMedia card to store all error, trace logs and a backup copy of the
system operating software and the customer database. The SmartMedia card is inserted into a
socket on the CTX processor. The CTX processor creates directories and files onto the card for
maintenance functions. Using CTX WinAdmin enables moving, copying, or deleting these files
without having to remove the SmartMedia card from the CTX processor. With CTX WinAdmin,
this works locally or remotely. SmartMedia files can also be managed by removing the
SmartMedia card from the CTX processor and inserting it into a PC SmartMedia card read/write
adapter.
Fault Detection and Error Logs
The Strata CTX detects and logs abnormalities that it encounters during operation. All error and
trace logs are stored on the SmartMedia card on the system processor and are monitored by
CTX WinAdmin. Examples are trunk failure detection and auto busy-out, digital telephone port
failure detection and auto busy-out plus error log, Expansion Cabinet power supply failure alarm
and error log, etc.
