INTRODUCTION

1.0 GENERAL

The TYMSERVE 2000 Network Ti e Server Operation and Technical Manual provides the

following infor ation:

- General Infor ation and Specifications

- Installation

- Operation and Network Interface

- Input/Output Connectors

1.1 TYMSERVE 2000 FEATURES

The salient features of the TYMSERVE 2000 include:

- User selectable ti e sources (-GPS, -IRIG versions):

GPS Satellite Receiver (-GPS version only)

IRIG B ti e code

Free running internal clock (ti e set by user)

External 1 PPS input

- -ACTS version uses the NIST Auto ated Co puter Ti e Service via telephone for

ti ing.

- Co patible with NTP (Network Ti e Protocol) Version 2 and 3.

- Supports both the DIX Ethernet and IEEE 802.3 (w/802.2 headers) ethernet fra e

for at. Connection via an AUI connector.

- Provides re ote status and configuration with both SNMPv1 and SNMPv2 using MIB-

II and a custo MIB extension.

- Provides a enu driven interface for setting up the Internet address and various other

para eters.

- Front panel ti e display (UTC or local ti e.)

- Provides rear panel Ethernet AUI and signal in/out.

- Provides IRIG B Ti e Code Output synchronized to the input ti e source (-GPS,

-IRIG versions only).

- Provides a 1 PPS (Pulse Per Second) output synchronized to the input ti e source (-

GPS, -IRIG versions only).

- Provides a 1, 5, or 10 MHz TTL output synchronized to the input ti e source (-GPS,

-IRIG versions only).

- Flywheels through loss of the ti ing signal to provide continuous NTP ti e service and

output ti e code.

- Optional rack ount ears. 1 3/4" high.

- Optional 8 ti e code output buffer (-TDM).

1.2 TYMSERVE 2000 OVERVIEW

The TYMSERVE 2000 is a self-contained pri ary ti e server which uses GPS (-GPS version

only), IRIG B ti e code, an internal free running clock, an external 1 PPS input, or (-ACTS

only) the NIST Auto ated Co puter Ti e Service (ACTS) as its ti e source. Utilizing the NTP

protocol (version 2 RFC-1119 and version 3 RFC-1305) over an Ethernet, the user can aintain

ti e synchronization a ong all co puters connected to the network. The NTP Server provides

the ti e server function which synchronizes other hosts on the network, and is never

synchronized by these other hosts. Utilizing NTP, synchronization of hosts to within 1

illisecond of the input ti e source is achievable under the best conditions. The -ACTS version

provides ti ing accuracies to within 10 s of UTC, but will still synchronize hosts to within 1

s of the TYMSERVE.

The -GPS and -IRIG versions of the NTP Server provide an IRIG B ti e code output

synchronized to the input ti e source. By using a ti e code reader odule installed in the users

co puter, ti e can be obtained (fro the reader) to accuracies on the order of 20 μsec.

Banco offers ti e code reader odules for the IBM PC bus, VMEbus, Qbus, STD bus, and

SBX bus.

The principal perfor ance characteristics are listed in Table 1-1.
