Configuration Steps 65 dial out prefix, leave the Dial Out Prefix field blank and enter that prefix value as part of the individual telephone number field itself (for example, '918005551000'). 13 In the Telephone Number 1 field, enter the telephone number that you obtained from your Network Administrator for accessing this private network. 14 (Optional) If your private network has a second remote access number, enter it in the designated field, and select Alternate or Multilink from the drop-down list (that is, choose whether you want to dial this second number as an alternate number when the first is unavailable, or whether you want to dial this number in addition to the first to create a high-speed, Multilink (112K) connection. 15 Under Security, enter your User ID and Password for accessing this private network (these may be case sensitive). 16 For DNS IP Address(es), enter the Primary DNS address of your private network in the Primary field, if required (that is, your private network does not automatically supply these addresses upon establishing a connection). If there is a Secondary address, enter it in the Secondary field. 17 Under Bandwidth Allocation, choose whether to always use one channel when dialing out to this private network, add the second channel as needed, or to always use both channels. 18 Under Private Network Parameters, enter the IP Address, Subnet mask and, if necessary, Domain Name of the private network. The IP Address and Subnet mask fields are mandatory. 19 Under Callback Parameters, check Enable Callback if you wish to have your private network's remote access (receiving) device drop your call and immediately call you back whenever you connect to the network; otherwise, leave this and the remaining Callback fields at their defaults. This function will only work properly if your remote private network supports Callback functionality. If you chose to enable Callback, make the following selections: s Callback Delay: Callback Delay is the amount of time the private network will wait before calling back this LAN Modem. By default this is set to 5 seconds. s Callback Timeout: Callback Timeout is the amount of time that the LAN Modem will wait (beyond the Callback Delay) for the private network to call back. By default this is 90 seconds. s Callback Number: Enter your first analog telephone number (this is the number to which the private network will place the Callback call). Note that if a different Callback number has been specified on the server end, the server callback number takes precedence. s Callback Username and Password: Enter the username and password of the callback user. These values are used to verify the server's authenticity to the client. If the server is another LAN Modem, these fields should match the login and password fields on the serve LAN Modem's dial-in user parameters. Note that callback authentication is optional. 20 Under Miscellaneous, make the following selections.

Multilink
from the drop-down list (that is,
choose whether you want to dial this second number as an alternate number when
the first is unavailable, or whether you want to dial this number in addition to the first
to create a high-speed, Multilink (112K) connection.
15
Under
Security
, enter your User ID and Password for accessing this private network
(these may be case sensitive).
16
For DNS IP Address(es), enter the Primary DNS address of your private network in
the
Primary field, if required (that is, your private network does not automatically
supply these addresses upon establishing a connection). If there is a Secondary
address, enter it in the Secondary field.
17
Under
Bandwidth Allocation,
choose whether to always use one channel when dialing
out to this private network, add the second channel as needed, or to always use both
channels.
18
Under
Private Network Parameters,
enter the IP Address
,
Subnet mask and, if
necessary, Domain Name of the private network.
The IP Address and Subnet mask fields are mandatory.
19
Under
Callback Parameters,
check
Enable Callback
if you wish to have your private
network’s remote access (receiving) device drop your call and immediately call you
back whenever you connect to the network; otherwise, leave this and the
remaining Callback fields at their defaults.
This function will only work properly if your remote private network supports
Callback functionality.
If you chose to enable Callback, make the following selections:
■
Callback Delay: Callback Delay is the amount of time the private network
will wait before calling back this LAN Modem. By default this is set to 5
seconds.
■
Callback Timeout: Callback Timeout is the amount of time that the LAN
Modem will wait (beyond the Callback Delay) for the private network to call
back. By default this is 90 seconds.
■
Callback Number: Enter your first analog telephone number (this is the
number to which the private network will place the Callback call). Note that
if a different Callback number has been specified on the server end, the
server callback number takes precedence.
■
Callback Username and Password: Enter the username and password of the
callback user. These values are used to verify the server’s authenticity to the
client. If the server is another LAN Modem, these fields should match the
login and password fields on the serve LAN Modem’s dial-in user
parameters. Note that callback authentication is optional.
