Caution
WireSpan 600 / 610 contains components sensitive to
electrostatic discharge (ESD). To prevent ESD damage,
avoid touching internal components and before moving
jumpers, touch the WireSpan 600 / 610 frame.
E1 Link Connections
WireSpan 600 / 610 E1 link has an RJ-48C eight-pin connector for the
balanced interface, and two BNC connectors for the unbalanced interface.
Appendix A,
E1 Balanced Port Connector
provides the pin allocation for
the RJ-48C connector.
Connector the E1 link cables to the connector(s) corresponding to the
interface in use.
Warning
Do not connect to both the balanced and unbalanced
connectors!
z
When using the balanced interface, connect to the
RJ-48C connector
z
When using the unbalanced interface, connect to the
two BNC connectors designated TX and RX. Pay
attention to the correct connection of the receive and
transmit cables to the TX and RX connectors.
The maximum allowable line attenuation between the
WireSpan 600 E1 link port and the network interface is
2-3
