Modem Environment

Hardware Installation

Before installing the Video Server, the administrator should memorize the serial numbers on the packages

respectively for the initial passwords.

To use a dial-up network, the Ethernet socket should be left disconnected since Ethernet is the first

priority among available interfaces. After powering up, the Video Server will detect if any external

modem is connected to the modem port. Once a modem is detected, the heartbeat LED will flash

periodically. If no modem responds, the Video Server will assume the included null modem cable is

connected to perform system configuration. Then both lower LEDs will turn on until null modem

connection is established.

If users have setup a remote dialup server or subscribed to an ISP service, the Video Server can be

configured to dial to the server upon special events. Otherwise it will wait permanently for the user’s call

to establish a network connection to provide services.

In the following content, dial-in connection denotes a passive the Video Server waiting for a phone call to

establish a point-to-point connection. Dial-out connection denotes an active the Video Server to dial out to

the other end of a dial-up server or any Internet service provider, abbreviated as ISP, to request a

point-to-point connection.
