The network port (Table 4-H) connects network management data to co-located radios
and the Telescan network management system. The high-capacity access panel accepts a
uni- or omni-directional (RS-422) connection. The omni-directional connection involves
setting the NMU to a 4-port bridge element (Figure 3-1-1). Jumpers on the Network
Bridge Interface (Table 4-I) behind the front panel set the network connector as uni- (E4
and E10 in) or omni-directional (E5 and E12 in) while NMU jumpers set the bridge
configuration.
SNMP Note See Appendix G to install and configure an SNMP Network.
Table 4-I lists the network connection pinning. Tx refers to signals out of the radio, Rx to
signals to the radio. Master/Slave and West/East labels refer to network (NMS)
configurations discussed above. To bridge network management data use connections as
Figure 4-10 illustrates.

Pin 1 is at the left of the jacks. Tx/RX signal direction is from the radio view. Tx means sig-
nals from the radio; Rx means signals to the radio.
