Features

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 on the primary shelf at the LET and at each RST. For redundancy, install an additional CPU-3 card at each terminal. The CPU-3 card supports ELU/EBC and ELU-3/EBC-3 spans for interconnections to expansion shelves.

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 either 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 the 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.
