HCPXCC03

HCPXCC03 cross-connect card performs processing, data path processing, cross-connect switching, fabric and timing functions. HCPXCC03 card supports bandwidth of 340G Higher Order cross-connects in the system.

HCPXCC03 card supports the following functional features:

Supports an equivalent bandwidth of 340G HO of non-blocking capacity.
Supports cross-connect card redundancy. In redundant mode, system will contain 2 such cards.
Switch to holdover in absence of selected primary and/or secondary reference clocks.
Responsible for protection switching, In-Band Communication (IBC), alarm handling, Order Wire (OW) byte and Over Head (OH) byte handling, User Interface (UI) provisioning and management of the node.
Supports temperature monitoring.
Supports 4GB disks.

The key functions of HCPXCC03 card are as follows:

Processor Function: HCPXCC03 card has a processor that performs the configuration, control and processing of all the other subsystems. The processor is a micro controller which has on board external memory to implement the required functions.
The software residing in this block controls the overall management of the system. This function is also responsible for implementing watchdog logic for the system.
Cross-connect Function: HCPXCC03 card has a non blocking 340G HO cross-connect capacity. HCPXCC03 card supports the cross-connect capacity with an equivalent bandwidth of 340G.
Synchronization Function: HCPXCC03 card has a Stratum-3 compliant clock generation unit. The PLL in synchronization unit can synchronize to a variety of timing sources, selected through the user interface.
Synchronization Status Messaging (SSM) is implemented in the software to propagate the clock quality information to neighboring elements and to select the best quality clock among a set of nominated clock sources. The synchronization unit is commonly called the timing module.

Front panel

The front panel has a two LEDs, Status and Active along with an early ejection switch. Apart from LEDs, the front panel has connectors for DIAG interface. OSC port is not supported in this product release.

Diag interface

The Diag interface is a USB connector provided on the front panel of the HCPXCC03 card. This interface offers a serial connection to node using which a user can launch a terminal session to log onto the Operating System.

NOTE: The diagnostic interface is meant for use by authorized Tejas Networks personnel only.
