Overview
The LCS60 supports the following protocols:
• TCP/IP • AppleTalk
• Serial Line IP (SLIP) • AppleTalk Remote Access Protocol (ARAP)
• Point to Point (PPP) • IPX
LAN to data switch connectivity between the resources of Ethernet LANs and
the data switch network is accomplished using the LCS60 (refer to Figure 3-1 for
an example of a data switch network).
1-4 Issue 3
Overview
The LCS60 provides the required hardware and software for the interface
between LAN and data switch network resources.
The LCS60 provides high-speed connectivity between Ethernet networks and the
Lucent Technologies family of data switches (Datakit II VCS 2.1 or greater, BNS1000, and BNS-2000).
Each LCS60 has the following components:
A CPU board to run the LCS60 software and to provide one Ethernet LAN
interface
A VMEDKHS board to provide a fiber interface to the data switch CPMHS trunk board
Communication between boards within the LCS60 is handled over a VME bus.
Benefits
The LCS60 expands the connectivity and enhances the functionality of the Lucent
Technologies data switch product line by allowing LAN and data switch network environments to communicate. Some of the benefits include:
Features
Device-to-device connectivity over multiple LANs
Improved capability to develop and use distributed processing environ-
ments
Access through the most commonly used network protocols
Data switch network access to LAN data
Modular design which permits easy expansion as needs increase.
Issue 3 1-5
LAN Protocols
TCP/IP
IP traffic is commonly associated with the Department of Defense (DOD) TCP/IP
Features
suite and is often run over Ethernet LANs. The LCS60 allows asynchronous endpoints, such as a terminal or host connected to a data switch, to log onto any Ethernet TCP/IP LAN host by using the LCS60’s async-to-TCP gateway service. The
LCS60 provides the terminal user with an interface to the TCP/IP telnet command, which allows the network user to remotely log onto LAN hosts via a vir-
tual terminal.
Conversely, an Ethernet TCP/IP LAN host can use the LCS60’s TCP-to-async
gateway service to access any asynchronous device (host, modem pool, etc.) connected to the data switch network. The LCS60 terminates the TCP/IP telnet
command initiated by the LAN host and provides the LAN user with asynchronous connectivity to the data switch network.
Domain Name Server (DNS) Resolver
The LCS60 can be configured as a Resolver in the DNS; this allows the LCS60 to
access a DNS Server for the translation of symbolic names into IP addresses.
This reduces the administration required for the LCS60. This feature provides a
less cumbersome and more efficient mechanism for performing translations
between symbolic host names and Internet addresses than checking the LCS60
database files.
The DNS function is a more manageable translation mechanism for large and
interconnected networks. It can connect to a name server (which maintains the
information database) on another host on the local or remote network.
The LCS60 default operating environment is still the use of the local host file. If
dns service is selected, the system will act as a resolver only.
Simple Network Management Protocol (SNMP)
SNMP software allows the LCS60 to report its TCP/IP status to an SNMP
Manager. SNMP service can be started and stopped using the lcsadm interface
of the LCS60. Implicit in the SNMP architectural model is a collection of network
management stations and network elements. Network management stations execute management applications which monitor and control network elements.
Network elements are devices such as hosts, gateways, terminal servers, and the

LAN Protocols
like which have management agents responsible for performing the functions
requested by the network management stations. SNMP is used to communicate
management information between the network management stations and the
agents in the network elements.
The LCS60 supports the standard SNMP management information base (MIB-II).
Refer to RFC 1213.
Supported Traps and MIBs
The generic traps that are supported are:
0 = cold start 3 = link up
2 = link down 4 = authentication failure
Routing Information Protocol (RIP)
The LCS60 supports RIP processing, i.e., handling IP routing information
through the use of routed. routed maintains the route table used by IP to determine the interface through which to send packets.
The LCS60 enables the administrator to start and stop routed service separately
using the lcsadm interface. In addition, the administrator can configure this service to be started at boot time.
Features
AppleTalk Protocol
The AppleTalk network system was developed to provide a link-independent
architecture to connect Apple and non-Apple network devices. AppleTalk provides a simple peer-to-peer protocol which allows any network device to communicate with any other network device running AppleTalk software.
The LCS60 can be used as an AppleTalk router connecting the Ethernet LAN to a
virtual AppleTalk network. The virtual AppleTalk network created by the
LCS60 permits as many as 120 remote AppleTalk devices to dial in over the data
switch and connect to the AppleTalk internet. The virtual network on the LCS60
supports a single network number and zone name.

AppleTalk Network Number and Zone Assignment
The LCS60 supports dynamic AppleTalk address assignment within a virtual zone
of PPP and ARAP clients. (Refer to Figure 1-2.) Upon dialing into the LCS60, the
PPP client is assigned an available network and node number automatically. The
client then becomes part of the virtual zone configured on the LCS60; no special
dialstring options are used.
