Configuration – Network > Interfaces > DialServ
The Dialserv option module mimics a telephone exchange in that it supplies the required
voltages on the line, generates a RING signal and has off-hook detection circuitry. It can be
used to provide similar functionality to dialling into an ISP using an analogue MODEM. The
card also contains an analogue MODEM to handle data on the line.
Use PPP/Protocol Switch
These radio buttons select whether the DialServ card uses a PPP instance or the protocol
switch functionality to control traffic on the interface. If PPP is selected, the web page
expands to reveal the standard PPP configuration settings. If Protocol Switch is selected,
only the four settings described immediately below are visible.
Max time to RING line s seconds
The value in this text box specifies the maximum number of seconds that the RING signal
should be generated for.
RING frequency n Hz
The DialServer module generates a RING signal – the frequency of the RING is selected
from this drop-down list. The available options are; 20Hz, 25Hz, 30Hz, 40Hz and 50Hz.
Initialisation string 1
The text string in this text box contains any required MODEM initialisation commands.
Initialisation string 2
The text string in this text box contain initialisation commands that will be issued to the
MODEM after the first initialisation string.

Settings
The DialServ card may be configured to use PPP as the protocol to connect to the remote
peer and as such should be assigned a free PPP instance to use as part of the configuration.
If no PPP instance has been assigned and the module has been configured to use PPP, a link
to the PPP mappings page and message appear.
If a PPP instance has been assigned, the following configuration options appear:
This DialServ interface is using PPP n
This message simply indicates which PPP instance (n) is being used by the DialServ card.
Description
The value in this text box is a short string that describes the interface and is used as a
convenience when referring to the interface.
Dial out using numbers
These four text boxes contain the telephone numbers that should be used, in sequence, to
make an outgoing connection. These can be used to provide a dialback facility.
Prefix n to the dial out number
The value in this text box specifies the dialling prefix to use, if needed. This may be
necessary when using a PABX.
Username
The text string text box is the username that should be used when using the PPP instance to
connect to the remote peer.
Password
This text box contains the password to use for authenticating the remote peer and is used in
conjunction with the above username.
