USRobotics NETServer/16, NETServer/8 manual Dial Group, Maximum Ports

Dial Group

This field specifies which group of modems will dial-out to a remote location. Group numbers can range from 0 to 99. The default group, 0, can be thought of as the group of all modems which have not been assigned to a different group.

set location <location> group <group #>

Specifying a modem group lets you reserve a modem for dialing specific locations, or ensure that the modem used for a connec- tion is configured correctly for this location.

Such groups are created during port configuration by setting the Dial Group of one or more modem ports to the same number.

Maximum Ports

This sets the number of ports the NETServer can allocate for a single connection to this location. Use the following command:

set location <location> maxports <number>

Possible Values for <number>:

0(Default) Dial out to this location is disabled.

1The NETServer will allocate only a single line to a session, regardless of the High Water Mark setting.

2+ When the High Water Mark is exceeded, the NETServer will allocate additional lines until this total is reached or there are no more free modems in the location’s dial group. This option is valid only if the device on the other end of the connection is another NETServer.

If the session is using multiple lines, the NETServer uses load balancing to maximize throughput and the Idle Time-out setting determines when to disconnect the additional lines.

For example, a local user connects to a location with a High Water Mark of 100 bytes and a Maximum Ports setting of 2. If the user is transferring large files, the traffic on that session’s line would exceed the High Water Mark. The NETServer would allocate another line to handle the file transfer, closing the additional line when the traffic level decreases.
