The UTM mates with the CEY5 (or CEY6) I/O board in support of the UTM connectivity options.
The CEY5 (or CEY6) I/O board contains all the necessary connectors the UTM requires for
currently available Console and 10BaseT LAN connections.
Note: Cables and adapters are available

2.4.1 S ERIAL
The UTM Serial interface is software configurable. Options are as an RS-232C DTE for serial
rates up to 64Kbps or as a V.35 DTE for serial rates up to E1.
2.4.2 C ONSOLE
The UTM Console interface may be used for console activities and the initial configuration. It
assumes the connected device is configured as 9600 baud, 8 bits and no parity.
2.4.3 LAN
The UTM LAN interface is used for IP network connectivity. It simultaneously supports IP-DSU
style BNS trunks and Internet peer level protocols (e.g. IP, TCP, UDP, ICMP and SNMP). The
LAN interface supports 10BaseT.
2.4.4 DSU
The UTM DSU (4-wire) interface is software configurable for T1 or E1 rates. A value of T1 is used
for domestic 1.544 MHz interfaces with 193 Bit Superframes. A value of E1 is used for European
2.048 MHz interfaces with 256 Bit Superframes. The DSU functionality is built in. This interface
may be used for connectivity to TDM Trunks, Frame Relay and ATM networks.
