Connecting E1 Signals to Measure
Connecting E1 Signals to Measure
Once the REF IN signal is supplied, as described in the section Connecting the E1
Reference to TimeWatch Module , the E1 signal to be measured can be connected
to the TimeWatch module MEASURE IN port.
The E1 MEASURE IN signal to the TimeWatch probe module can be provided by
the SPAN 1 port of the TP500 slave module, or any E1 source. Use the following
procedure to connect the ports with the BNC-to-BNC cable included in the
TimeAnalyzer 7500 ship kit .
1. Connect the staight BNC connector of the cable to the SPAN 1 BNC port on the
TP500 module, as shown in Figure 2-19 . If an E1 signal from another source is to
be measured, use a cable of appropriate length to connect to the E1 output of
that source.
2. Connect BNC connector on the other end of the cable to the MEASURE IN port
on the TimeWatch module, as shown in Figure 2-19 . If an E1 signal from another
source is to be measured, the cable must have a BNC connector (or BNC
adapter) to connect to the TimeWatch module MEASURE IN port.
3. Connect an Ethernet cable into the 1588 port on the TP500. See Figure 1-8 .
4. Plug the other end of the Ethernet cable directly into the network, as shown in
Figure 4-2 . (Symmetricom recommends that PTP signals be connected directly
to the network rather than through TimeAnalyzer’s 5-port switch.)
