INTERFACES

n Both the LAN and WAN link

interfaces are modular, and

accommodate several standards.

n LAN:

The Ethernet/802.3 LAN interface

options supported are:

– AUI (10Base5)

– BNC (10Base2)

– UTP Ethernet (10BaseT).

n WAN:

WAN link interface modules include:

– V.24/RS-232, which can be

configured for asynchronous

operation over dial-up modem

links. These links operate at

data rates from 2.4 kbps to

115.2 kbps. Use of

compression modems

improves performance and

throughput of the MBEs.

– Digital interfaces (V.24/RS-

232, V.35, X.21, RS-530 and

V.36) for synchronous leased

lines at data rates up to 1.5

Mbps

– Built-in CSU/DSU for

connection to leased lines

operating at up to 56 kbps.

– An internal ISDN terminal

adapter module.

Two B channels are available

on the dual port module as well

as one redundant link

(sync/async). ISDN switches

supported include 5ESS, and

DMS-100. The ETSI NT1

European standard, and I430

are also supported.

– A built-in 4-wire, short range

modem. This option permits

operation at data rates up to

768 kbps (See Figure 5, and

Table 1). It is suitable for

campus or factory

environments where either a

single station or a workgroup

LAN requires connection to the

LAN, beyond the distance

normally attainable over

copper media. The 4-wire

interface model has an internal

clock with selectable data rates

from 16 kbps to 768 kbps

according to the required

range.

Figure 2 - An MBE can be used to simultaneously provide

dial-in capability for standard PPP dialer

PCs/laptops to the office and uplink connectivity to

the Internet for use by users in the office as well as

teleworkers
