ADSI
ADSI (Analog Display Service Interface) is a telecommunications protocol standard that enables alternate
voice and data capability over the existing analog telephone network. It is an extension to basic caller ID. To
use ADSI, you would need an ADSI capable device.
ADSI can display the basic caller ID parameters and the following additional parameters:
 Call Type
 First Called Line Identity
 Number of Messages (MWI)
 Type of Forwarded Call
 Type of Calling User
 Redirecting Number
 Charge
 Duration of the Call
 Network Provider Identity
Setting the Location (Country)
It is very important to set variables according to the country in which the Mediatrix 4100 is used because a
number of parameter values are set according to this choice. These parameters are:
 Tones
 Rings
 Impedances
 Line Attenuations
See “Appendix D -
Country-Specific Parameters” on page 207 for more information on these country-specific
settings.
 To set a country location:
1. In the telephonyMIB, locate the telephonyCountrySelection variable.
This variable indicates the current country used by the Mediatrix 4100. It can also be used to select
a caller ID standard in countries that support more than one caller ID standard.
Note: The compatibility of the Mediatrix 4100 is not limited to the above caller ID standards.
Note: Currently, very few ADSI-capable devices support these additional information.
