10: Modem Sharing

Modem sharing provides users with individual modem/phone line functionality at a reduced cost. When
modems are shared, a group of IP users may use a modem pool to dial out of a LAN and connect to a remote
host; for example, to connect to a bulletin board service (BBS). This eliminates the need for phone lines for
each user's computer.

10.1 Services

A service represents a resource accessible to network users, such as a modem or a pool of modems attached
to the SCS.
Services provide links for TCP connections to SCS serial ports. They are employed in modem sharing to
establish connections to the SCS modems.

10.1.1 Creating a Service

Each SCS service must have a unique name. To create a service, use the Set/Define Service command. An
example is displayed below.
Local>> DEFINE SERVICE fastmodems
Service names are not case-sensitive, may be up to 16 alphanumeric characters long, and cannot include
spaces.

10.1.2 Associating Ports with a Service

Each service must be associated with at least one port. To associate a port with a service, use the Set/Define
Service Ports command.
Local>> DEFINE SERVICE fastmodems PORTS 2
Set/Define Service Ports is discussed in detail on page 12-105.
Note:
To use a service for modem sharing, the service should be associated with multiple ports; this permits
multiple connections to the service. Connections will be made to the first available port.
