3.10.3.3 LAN Port
The LAN port on the MIU-201 is an 8-pin RJ48 modular 10/100BASE-T (10 or 100 Mbps) Ethernet
port. When provisioned on the NIM-1, the LAN port can act as a redundant WAN interface. Use a
standard Category 5 or better twisted-pair cable to connect LAN to an Ethernet switch. The port is
auto-sensing, so you can connect to uplink ports on a router as well as standard port connections.
Table 3-5 gives LAN port pin assignment information.
3.10.3.4 T1/E1-A Port
The T1/E1-A port on the MIU-201 is an 8-pin RJ48 modular synchronous T1 (1.544Mbps) or E1
(2.048Mbps) bidirectional interface for interconnection with external T1 or E1 based devices or
networks. Use an EIA/TIA T568A or T568B wired Category 5 or better twisted-pair cable to connect
T1/E1-A to the external T1 or E1 circuit or equipment. Do not use USOC wired cabling for this
connection, as the pairs are not twisted in the required combinations. Table 3-6 gives T1/E1 port pin
assignment information.

3.10.3.5 T1/E1-B Port
The T1/E1-B port on the MIU-201 is an 8-pin RJ48 modular synchronous T1 (1.544Mbps) or E1
(2.048Mbps) bidirectional interface for additional interconnections with T1 or E1 based devices or
networks. Use an EIA/TIA T568A or T568B wired Category 5 or better twisted-pair cable to connect
T1/E1-B to the external T1 or E1 circuit or equipment. Do not use USOC wired cabling for this
connection, as the pairs are not twisted in the required combinations. Table 3-6 gives T1/E1 port pin
assignment information.
