Chapter 1 Overview
TimeProvider 500 Client Module
T1/E1 Frequency Output Connectors
The TP500 Client module provides configurable outputs at either E1 (2.048MHz) or
T1 (1.544MHz) frequencies. Specific signal types at each frequency are detailed in
the CLI command, set output signaltype, as described in. Both outputs must be the
same signal type. There are two independent, separately driven outputs, labeled
SPAN1 and SPAN2. For differential connection to the TP500 Client moduleeither
output, use the appropriate RJ-48C connection shown in
Figure 1-8 . SPAN1 is the
upper connection and SPAN2 is the lower connection. For single-ended connection
to either output, use the BNC connectors shown in
Figure 1-8 .
LEDs
At the center are four LEDs:

PWR illuminates green when the unit is powered.

SYNC provides high-level status indication. The indications and associated
meanings are described later in this document.

OUT illuminates green when output is being generated on the SPAN
connections.

ALARM illuminates Red to indicate a CRITICAL or MAJOR active alarm, AMBER
to indicate MINOR alarm. Current alarm status can be checked using the show
alarm command. For more information, see the CLI command, show alarm, in
the TP500 User’s Guide.
RS232 MGMT Serial Port
The DE9 connector labeled RS232 MGMT provides a local serial connection to the
TP500 module. Through this connection, a Command Line Interface (CLI) provides
configuration and status monitoring capability. The RS-232 serial port connection is
made through a DE9S female connector. This port allows you to connect to a
computer using terminal emulation software for remote monitoring an control. When
connecting to this port, use a shielded direct connect cable. See
Provisioning the
TP500 PTP Client Module , on page 77, for default settings.
IEEE 1588 Remote Management Port
The RJ-45 connector labeled “1588” is the connection into the network that is
providing the grandmaster clock(s). This same connection is also used for remote
management.
Note: The outputs from the left BNC and lower RJ48C connection
(both labeled SPAN1) are generated from the same driver circuit, so
for proper signal level only one of those connections should be used
at any one time. The same situation applies to the right BNC and
upper RJ48C, both labeled SPAN2.
