Ethernet Configuration Guidelines

• Two METROWAVE Bridges connected by a microwave link count as two in the seven bridge limitation .

• Although it is packaged with an H4000 transceiver, the METROWAVE

Bridge can also be attached to standard Ethernet cable using a DELNI. to ThinWire cable using a DESTA, or to broadband cable using a DECOM.

The following figure illustrates the Extended Baseband LAN configuration and distance guidelines.

Distributed System Cost Parameters

• Advantages

Lower communication costs

Modest startup costs (see below)

Low incremental expansion cost

Higher share of raw computing power available to the user

Better cost performance; faster reaction to new technological advances

Higher availability

• Disadvantages

High costs for extensive conversion

Distributed Systems Personnel Parameters

• Greater interest and motivation at local level.

• Identification with task of individual department's organization.

• More opporrtunities to communicate with and transfer into line management.

• Fewer skilled personnel required at each site.

Factory Applications

Figure 2.9

Overview

The following figure illustrates a typical application of Ethernet in a factory. Such a configuration provides control of automatic assembly/test devices. Data entry stations provide timely information on the entire manufacturing process. Exchange of data between the manufacturing site and the rest of the corporation is handled through a router server.

• Specifies the communication interface between DTEs and DCEs on the PPSN.

• Defines three functional levels (similar to RS232-C and to the lower levels of DNA).

Level 1 (Physical Interface) - Defines the physical and electrial characteristics of the connection between the DTE and the DCE.

Level 2 (Frame Level) - Defines the rules for transmitting data between the DTE and DCE.

Level 3 (Packet Level) - Defines the rules for transmitting and controlling the packet.

• CCITT's X.3, X.28, and X.29 recommendations define an interactive terminal interface for devices such as

ansynchronous hardwired terminals that want to communiclte over a PPSN, but cannot be programmed according to the X.25 format.

Digital's Interconnect Strategy with IBM

To create an environment which accommodates t.he

transparent,

bi-directional flow of information

between Digital and IBM data

processing systems.

(116)

(

Complementary Computing

• Gateway concept

Provides access between the Digital and IBM

processing

environments

Allows either vendor's

netwo.rk

to expand based on the

customer's needs

(

• User Transparency

Insulates the users and their applications from changes

in the network

Allows for

~nhancements

and changes in either network

• Provide a

Network-to-Network

solution between the two

vendors

- Viable in any arbitrary topology supported by DECnet
