1 Abstract

This document provides a technical description of Odin TeleSystems’ Sleipnir-1-PCI
adapter card. This presentation is targeted to systems integrators and application
developers who are developing telecommunications systems and/or software applications
using the Sleipnir-1-PCI platform. The purpose of this document is to provide the needed
information about the hardware to allow software developers to efficiently integrate
Sleipnir-1-PCI into their overall system under design.

For information on how to develop host applications utilizing the OTX Hardware Device
Driver Application Programming Interface (API), please refer to the “Programmer’s
Guide for OTX Hardware API” document (Odin TeleSystems Inc. document number
1411-1-SAA-1006-1). For information on how to develop custom DSP applications,
please refer to “Programmer’s Guide for OTX C54x DSP Software Development Kit”
(Odin document number 1412-1-SAA-1007-1). And finally, for help on how to install the
Sleipnir-1-PCI card and the OTX Device Driver Software, please refer to the Installation
Guide for OTX PCMCIA Adapters (Odin TeleSystems Inc. document number 1512-1­HCA-1003-1).

2 Sleipnir-1-PCI Overview

Sleipnir-1-PCI is single span T1/E1/J1 adapter for the PCI Local bus. It is available in
two different configurations:

• LAN (Local Area Network) and WAN (Wide Area Network) configuration

• Telecom configuration.

The Sleipnir LAN and WAN configuration is supplied with a network driver and
supporting software to allow high speed PPP and Frame Relay connectivity. No
programming is needed in this configuration.

The Sleipnir telecom configuration is a member of the Odin Telecom frameworX (OTX)
product family. It is supported by the OTX device driver and by the OTX Hardware
Application Programming Interface (API). It is populated with a Texas Instruments
TMS320VC5510 400 Mips DSP and 16MB external memory. Equipped with the
appropriate OTX software modules, Sleipnir-1-PCIcan be utilized in a variety of T1/E1,
Integrated Services Digital Network (ISDN), Frame Relay, and Signaling System #7
(SS#7) applications.

The Sleipnir-1-PCI supports a single T1/J1 or E1 interface at the speeds of 1.544 Mbps
and 2.048 Mbps, respectively. The same board supports both T1/J1 and E1. The Sleipnir­1-PCI is available with two different connector options:

4 Data Architecture

Internally, Sleipnir-1-PCI utilizes serial TDM (Time-Division Multiplexed) data streams
for transfer of data or voice. The internal serial TDM data streams are called “Highways.”
The external interface is referred to as “span”.

The serial highways provide data paths between physical devices as shown in the figure
below.

5 PCM Highways

The Sleipnir-1-PCI utilizes 2 Mbit/sec PCM highways for data routing. When the
optional DSP is installed, the DSP can process data from ether the incoming data stream

or from the host by way of DMA transfer. The DSP can supply data to ether the outgoing
data stream or the host by way of DMA transfer.

6 API Supported Physical Devices

6.1 Board Devices

The Sleipnir configuration and status registers are accessible by API calls. The board
devices include the serial to parallel converters and the DMA controller. The application
can read or write the data directly from the Sleipnir buffers, or have the DMA controller
place the data in the host memory and notify the application when data is available.

6.2 T1/E1 Line Interface Device

The Sleipnir Line Interface device fully supported by API calls to configure the interface
for the required functionality. There is full access to all device registers for monitoring or
diagnostics.

6.3 DSP

The optional DSP on the Sleipnir can be used to run Odin provided standard DSP
applications or they can be used to run user developed custom applications. The Sleipnir
telecom configuration is delivered with a number of Odin’s Signal Processing Module
(SPM). These SPMs, or DSP application packages, provides supports for many common
telecom applications; such as tone detection and generation, FSK detection, and HDLC
sending and receiving.

For more information on custom DSP application development, please refer to “Pro-
grammer’s Guide for OTX C54x DSP Software Development Kit” (Odin document
number 1412-1-SAA-1007-1)

etc)

• Support for generation and detection of Loop codes

• Support for channel loopback

• Support for PRBS (BERT patterns)

9 PCI Bus

The Sleipnir-1-PCI board is compliant with the PCI 2.1 local bus specification. It is a
universal interface, supporting both 3.3 volt and 5 volt signaling. The Sleipnir-1-PCI
supports 32 bits at 33 MHz and can be both Slave and Master.

12 JTAG

On the Sleipnir-1-PCI board, all the internal TDM data highways and the all the devices
processing TDM data are synchronized to one clock reference. The clock reference can
be derived from multiple sources and then routed to all the devices. The following clock­ing sources are supported by Sleipnir-1-PCI:

• Clock extracted from the incoming T1/E1/J1 span

• External 2.048 kHz clock (J3 connector)

• On-board free running oscillator

The J2 connector can be used to output the Sleipnir-1-PCI clock reference to another
device or equipment.

The JTAG port (reference designator J1) are used for Board Testing, programming of
The FPGA PROMS, and Connecting the DSP emulator board for DSP Software
Development.
