The Central Processing Unit 3 (CPU-3) plug-in card enables end-to-end system control of the Tellabs 1000 Multi-Service Access Platform from the primary shelf at both the LET and RST nodes. The card supports both ATM, Ethernet and TDM connections while performing system initialization, provisioning, alarm reporting, maintenance, diagnostics, and fault detection for the Tellabs 1000 MSAP system.
Precise Timing
The CPU-3 selects timing sources, synchronizes to external timing sources, and provides a high-stability internal timing reference. The CPU-3 card meets SONET minimum clock requirements for holdover and free-run accuracy.
High Reliability
Install a minimum of one CPU-3 plug-in card in the primary shelf at the LET and at each RST. For redundancy, install an additional CPU-3 card at each terminal. For interconnections to expansion shelves, the CPU-3 card supports ELU/EBC and ELU-3/EBC-3 spans simultaneously.
Easy Management
The CPU-3 plug-in card contains the menu-driven Tellabs 1000 Craft Interface software. Connect to the Craft Interface with a simple terminal, such as a VT100, to perform system administration, maintenance, testing, and provisioning. Access the Craft Interface using the standard RS-232 port located on the air ramp portion of the CBA, through wire-wrap backplane pins, or through a LAN connection using the IPMI plug-in card.
Connection Admission Control Functions
The CPU-3 card hosts the systems Connection Admission Control (CAC function). CAC initiates, maintains, and tears down virtual channel connections set up by the user. The CPU-3 manages bandwidth and controls allocation of VPI/VCI resources.
Call Control
The CPU-3 plug-in card controls call processing for the Tellabs 1000 system. It allocates timeslots for subscribers who have gone off-hook, cancels time slots for terminated calls, relays provisioning information to and from subscriber interfaces, and provides automatic concentration during span failures.
