Chapter 1 Overview of the TimeProvider
Communication Ports
The procedure for installing power is described in Making Power Connections, on
page 54.
Communication Ports
The TimeProvider contains three communications ports that allow you to provision,
monitor, and troubleshoot the shelf. The Ethernet and Remote serial ports are
located on the shelf, and the local Craft serial port is located on the IMC. You
communicate with the TimeProvider using the TL1 protocol.
You can select one of four security levels for each user; each level has varying
levels of access to provisioning parameters. See Defining the Security Parameters,
on page 90.
Ethernet
An Ethernet connector provides connectivity to an Ethernet local area network.
Each main shelf has a unique internet protocol (IP) address. Once the IP address is
set and a connection is made to a LAN, you can access the TimeProvider on an
intranet.
The Ethernet port supports up to 10 simultaneous connections to port 5000.
Local Craft Serial Port
This EIA-232 port supports local control; you can configure the TimeProvider with
TL1 commands using a terminal or personal computer (PC) with terminal emulation
software or Symmetricom’s craft software, SynCraft. The connector is located on
the front panel of the IMC. The default specifications are 9600-8-N-1. The Local port
is configured as a DCE interface.
Remote Serial Port
The Remote serial connector can be used in the same manner as the local Craft
serial port. The Remote port has additional control support to manage an external
modem for remote access. The Remote port is configured as a DTE interface.
