2.2.2 Console
The UMI 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.
2.2.3 10/100 BaseT and Fiber LAN
The DTK41 LAN and Fiber ports are used for IP network connectivity. The UMI supports Internet
peer level protocols (e.g. IP, TCP, UDP, ICMP and SNMP). All of the 10/100 ports are fully
switched, not bridged. The capacity of the switch is over 1Gbps. The 10/100 and Fiber ports are
managed from the UMI console. Each 10/100 port and the Fiber port may be enabled or disabled
individually. Alarms are generated if a link is established, or if a link is lost.
An advanced feature DTK41 is that no crossover cable is ever required on the 10/100 ports. The
10/100 ports will automatically correct for the cabling mismatch.
The 10/100 ports will self-configure to match the speed of the link (10 Mbps or 100 Mbps ), and
the Duplex ( Full or Half ). No configuration is required.
The Fiber interface connects to the industry standard SC cabling. If ST cabling is used, the
DTK41 ST plug-in module is used. No adapter cables are required.
2.2.4 DSU
The UMI does not utilize the DSU interface at this time. The DTK41 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, Frame Relay, and ATM networks.
2.2.5 Variants
The DTK41 high performance I/O board is available with two different mounting brackets. The
DTK41N incorporates a mounting bracket specifically designed to be installed in a BNS node, a
Datakit VCS node, or an MPC. The DTK41S has a mounting bracket specifically designed to be
placed in a SAM504, SAM64, or SAM128. It is anticipated that the UMI shall use only the
DTK41N variant of the DTK41.
