Caller ID Detection Range
The standard used to detect the caller ID on a Mediatrix 1204 requires that the full range of the signal (12 mV
RMS to 476 mV RMS) be supported. Because of a limitation to the Mediatrix 1204, it cannot detect a caller ID
signal on the whole range defined by the standard. The Mediatrix 1204 thus offers the possibility to set two
detection ranges. This applies only to SCN to IP network calls.
X
To set the caller ID detection range:
1. In the fxoMIB , define the range you want to use in the fxoCallerIdDetectionRange variable.
Available values are:
• high: Caller ID b/- 30 mV RMS and 530 mV RMS
• low: Caller ID b/- 7 mV RMS and 110 mV RMS
The higher range is the default and should accommodate almost all situations.
Caller ID from SCN
The Mediatrix 1204 displays the caller ID information from a SCN caller. If the caller ID is not available, the
unit displays the alias of the corresponding line.
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
Note:
The Mediatrix 1204 supports caller IDs up to a maximum of 31 characters. However, the Mediatrix
1204 can only display a maximum of 15 digits. If the phone number exceeds 15 digits, the caller ID is not
displayed.
Note:
Currently, very few ADSI-capable devices support these additional information.
