The names of ports in Hunt Groups must be unique. Otherwise

ports with names that are similar or identical to the Hunt Group,

will also be included in the Hunt Group.

Hunt Group Example 1:

1. Assume MDS Ports 1 and 2 have been configured in the

Any-to-Any Mode, and modems have been installed at both

ports.

2. Assume Port 1 has been named "MODEM1" and Port 2 has

been named "MODEM2".

3. If your resident port is Port 4, and you want to connect to

the first available Modem, access the MDS Command

Mode, type

/C MODEM

[Enter]

.

Hunt Group Example 2:

1. Assume Ports 3, 4, and 5 have been configured in the Any-

to-Any Mode and printers are attached to each port.

2. Assume all three ports have been named "PRINTER".

3. If your resident port is Port 1, and you want to connect

Port 2 to the first available printer, access the MDS

Command Mode, type

/C 02 PRINTER

[Enter]
