Multiserver 5000

EXAMPLE OF A SWITCHING CLASS

Figure 10-4shows a Multiserver network. The Central Office has a Multiserver 5000 with a

6-channel CEM and 3 Voice/Fax cards. This will be considered the local node. Each remote office has a Multiserver 1000 with one Voice/Fax card.

In this application, the remote Voice/Fax channels will be able to reach the local PBX at all times. However, there are twelve remote data terminals (four in each office) and only six available connections to the host computer.

This is a situation where a switching class is ideal. If the host had twelve free ports, the network manager could just force connect each remote terminal to one port on the host. As the situation exists, the network manager will make the six host ports a switching class, allowing the twelve remote ports to contend for free ports on the host. When a remote terminal attempts to access the class (local ports B1 to B6), the Multiserver 5000 will connect it to a free channel on the 6-channel CEM. If all channels in the class are busy, the remote terminal will be placed in queue. The Multiserver 5000 will connect the queued channel to the host when another remote terminal times out or disconnects.

PLANNING A CLASS

Before configuring the classes, define which ports are to be grouped together and note the following information:

Class Name	The group of ports that is
	searched when this class name is
	requested.
Class Name	Switching class names and LAN
Syntax	class names must be unique.
Secondary Class	An alternate switching class that
(if applicable)	is searched when all ports in the
	primary class are unavailable.
Class Password	The password assigned to each
	class.
Class Message	The message appears when the
	user attempts to connect to the
	class. CONNECTED appears when
	the user is connected to the class.
