CHAPTER 1
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.
