  • Page 22: Overview Of The Eiu

    Overview of the EIU The EIU is an application-specific unit (ASU) that supports Ethernet connectivity on the DMS-100 switch. You can configure the EIU as either an IP router or an OSI router. The EIU also supports host services. The EIU is intended primarily as a high-speed interface that provides connectivity in a co-located environment such as that in a Central Office.

  • Page 33: Grounding Requirements

    The card provides a 4-wire twisted-pair connection externally. Up to four external LAN devices can be connected to the hub. This development provides a cost reduction over an OEM 10BaseT LAN configuration and puts maintenance of the hub more in line with standard DMS-100 maintenance practices. Grounding requirements Isolated system ground (ISG) is not mandatory.

  • Page 34: Eiu Hardware Capabilities And Limitations

    This capability follows the standard DMS-100 maintenance philosophy, which states that a node must be maintainable even under overload conditions. In a lab environment, it has been demonstrated that a moderately heavily loaded LAN with broadcast messages caused workstations and a router to lock up, while the EIU remained functional.
  • Page 35 SNSE LIS, System Engineering Bulletin SEB 92-02-001. • The DMS-100 switch supports a maximum of eight EIUs per switch. Each of the eight EIUs can be configured on a separate LAN. However, EIUs configured on the same LAN can provide simple load balancing of IP traffic between EIUs, and tolerance to failure of a single EIU.

  • Page 36: System-Wide Limitations

    36 Chapter 1: Introduction to the EIU System-wide limitations The EIU is collocated in an LPP shelf with other ASUs such as the link interface unit (LIU7) and frame relay interface unit (FRIU). The exact configuration of ASU-type units depends on the applications. The LPP is connected to the DMS-bus through eight DS30 links in a load-sharing arrangement.

    All subnet size combinations are permitted in table IPNETWRK. However, the subnet size in the DMS-100 switch must be the same as the subnet size of the LAN to which the DMS-100 switch is connected. This requirement is a result of the limitation of the RIP version 1.0 implementation in the EIU.

    If the new value is zero, TCP remains out of service until a nonzero value number is datafilled for that node. The DMS-100 switch responds in the same way when the IP address of the node is modified while the node is in service. In this case, if the number of TCP connections remains the same or is increased, the reallocation is not required.
