## Introduction

-   Purpose of ORR/TRR:
-   Decide if the WDISC Expansion system is ready to
-            transition to operations
-   WDISC = WSC TCP/IP Data Interface Service Capability
-   Current WDISC:
-   2 prime Programmable Telemetry Processors (PTP’s)
-   2 hot-backup PTP’s
-   3 boards per PTP => at most 6 simo return data streams

## Introduction (cont)

-  WDISC customers will include:
-   Multiple simultaneous balloon flights (LDBP & ULDBP)
-   CNOFS, EO-1, FUSE, GALEX, GP-B, LSAT-7, SORCE,
-     Swift, TIMED, ...
-  2002 Loading Study
-   NASA recommended expanding the number of simo return
-     data streams to 12

**ORR/TRR Review Board**
- NASA SN STADIR: Jim Gavura
- NASA SN: Bryan Gioannini
- CSOC SN Management: Don Shinners
- CSOC SN Sustaining Engineering: John Follin
- CSOC SN Operations: Steve Sypher
- CSOC SN Maintenance: Barry Lusby

## Requirements

- Expansion system must satisfy the same requirements as current system as defined by:
- System Requirements (CSOC-GSFC-RD-002090)
- Service Specification (CSOC-GSFC-RD-002056)
- Interface Agreement with NCCDS (CSOC-GSFC-AGR-003001)

## Implementation

-   Plan, Procurement, and Configuration
-   Hardware Implementation
-   Software Implementation

## Implementation Plan, Procurement, and Configuration

- Plan was to procure five new PTP’s from the vendor (Avtec) who supplied the PTP’s for the original 1998-99 WDISC system because:
- Compatible with current WDISC system and NCCDS
- Proven performance of PTP’s
- Same interface for current WDISC customers
- Cheaper to add known PTP system than to re-engineer a new system
- Proven support from Avtec

## Implementation Plan, Procurement, and Configuration (cont)

- Plan was to build and configure the new system at GSFC because:
- Could minimize set-up, configuration, and testing once at WSC
- Engineering support available at GSFC
- WDISC experience available at GSFC
- Test equipment and space for development lab available at GSFC (e.g., FIREBERD, MMDPSX scheduling interface, frequency synthesizer, oscilloscope, IRIG signal generator)
- Some needed hardware was already available at GSFC (e.g., system racks, receiver-drivers, patch panels, bottle plugs)
- Cabling fabrication could be done at GSFC
- Management of WDISC Expansion Soda Task at GSFC

## Implementation Plan, Procurement, and Configuration (cont)

- Hardware/software was procured by GSFC:
- Current WDISC system was procured/tested at GSFC
- WDISC Expansion required basically the same hardware, but some changes were made to take advantage of new technologies:
- AB switch hardware improvement
- Avtec Monarch boards to support higher data rates
- New Avtec PTP’s provided more clock speed and RAM
- Spare PTP procured for testing and to provide operational spare
- All system and testing hardware was in place by 6/25/03

## Implementation Plan, Procurement, and Configuration (cont)

- Configuration at GSFC:
- Current operational Avtec desktops loaded on PTP’s
- Time server and delete 50-hours Perl script configured as they
-     are on current operational PTP’s
- Remote Administrator (Radmin) COTS product procured, tested, and loaded on all PTP’s
- Log-on accounts loaded on PTP’s to correspond with NT monitoring log-on accounts (for Radmin security)
- SchedServer GOTS, Ghost, and VirusScan loaded on PTP’s
- AB switches configured with password
- Shipped system to WSC on 9/25/03

## Implementation Plan, Procurement, and Configuration (cont)

- Configuration at WSC:
- Firewall updated for PTP IP addresses
- Domain Name System (DNS) updated for PTP names and IP addresses
- NCCDS data base updated for new User Interface Channels (UIFC’s) corresponding to new Local Interfaces (LI’s), SIC-UIFC-data-rate mapping tables, valid destinations, Service Specification Codes (SSC’s)
- NCCDS SPSR startup scripts updated for new scheduling client processes corresponding to four new PTP’s

## Implementation - Hardware 

- Contains newer version of Avtec PTPs with Monarch-E CMD/TLM boards and faster CPUs.
- Forward switch configuration collapsed into a single chassis per channel (3 rack mount units versus 9 plastic boxes).
- LCD monitor and keyboard tray (1 rack unit) replaces CRT monitor and keyboard (9 rack units).  This is shared with ISS SCDs on the same KVM switch.
- 5 MHz expansion provided by RS-422 bridges connected to remaining spare ports on Austron buffer in rack 7112.
