DSP Series 2 Plus Card

Introduction

The DSP Series 2 Plus card and Multi-Function Media I/O Plus card and the existing DSP Series 2 card and Multi-Function Media I/O card are supported for the 8.4.1 CI software release. This section describes any differences between these CSP cards and includes any additional hardware and software functionality.

The DSP Series 2 Plus card is functionally equivalent to the DSP Series 2 card and is also backwards compatible with the DSP Series 2 card. Both cards can be used in the same CSP chassis.

This section describes any differences between these CSP cards and includes any new hardware and software functionality.

Benefits to Customer

The DSP Series 2 Plus card provides the customer with the following:

• An upgraded platform for future DSP enhancements

• Meets Restriction of Hazardous Substances (ROHS) standard required for shipments to the European Union (EU)

Licensing Configuring and Querying

The licensing requirements for the DSP Series 2 Plus card are the same as required for the DSP Series 2 card.

The DSP Series 2 Plus card is configured and queried in the same way as the DSP Series 2 card.

Users must update their code so that the host will recognize the new DSP Series 2 Plus and Multi-Function Media Plus I/O board IDs.

Ethernet Architecture and Functionality

The DSP Series 2 Plus main board has the capability of providing the following six 10/100 Base-T auto-negotiating signals to the Ethernet ports on the Multi-Function Media I/O Plus card. For the this release of the DSP Series 2 Plus card, only the top two control Ethernet ports CTR 0 and CTR 1 will be used. These two ports are connected to the CPU processor and have their own MAC addresses. These ports provide for communication on the control plane (for example, matrix to host communication, NFS, RTP and redundancy).

Important! The four data ports DATA 0 - DATA 3 which are connected to the internal Ethernet switch will be disabled and reserved for future use.

Ethernet Link Redundancy

The DSP Series 2 Plus card supports Ethernet Link Redundancy over control ports CTR 0 and CTR 1. It does not support physically separated networks connected to each control port. Both ports perform as a logical interface with one port being active at a time. If the active link goes down, the hot standby port automatically takes over.

If the host does not configure the DSP Series 2 Plus for Ethernet Link Redundancy, then only control port CTR 0 should be used.

Hardware Compatibility

• The DSP Series 2 Plus card may reside in a CSP that also contains DSP Series 2 and DSP-ONE cards, and the platform can pool identical resources from these cards and use them together.

• The 2090 chassis can accept a maximum of five DSP Series 2 Plus cards, while the 2040 chassis can accept a maximum of two DSP Series 2 Plus cards.

• The DSP Series 2 Plus card may not reside in an CSP that also contains MFDSP cards.

Modules and DSPs

The DSP Series 2 Plus card comes with either one or two DSP 2 Modules with four DSPs each, for a maximum of eight DSPs per card.

RAM, Flash Memory and Processor Speeds

The DSP Series 2 Plus card main board has 128 Mbyte of external synchronous SDRAM and 2 MBytes of Flash memory. Both the CPU and I/O processors are faster. The CPU supports a 450 Mhz processor and the I/O supports a 100 Mhz processor.

I/O Card

The DSP Series 2 Plus card requires the Multi-Function Media I/O Plus card for I/O functionality.

API Changes

The DSP Series 2 Plus functionality does not require any new API messages. The following two API messages have been modified:

• Card Status Query (0x0083)

• Card Status Report (0x00A6)

The Card Type field has been modified with new card types and card IDs as follows:

• 0x90 DSP Series 2 Plus

• 0x92 Multi-Function Media I/O Plus
