The Ch N parameters are repeated for each channel in the line. There are 23 channels if you use
PRI signalling, and 24 channels if you use robbed-bit. (For more information about each
parameter, see the MAX Reference Guide.)
At the top level, you can assign a name to the line configuration. You can configure several
profiles and activate a profile when it is needed.
You can set line 1 and line 2 to Trunk (indicating a standard T1 interface with signalling
information) or Disabled.
Understanding the line interface parameters
This section provides background information about the T1 line interface parameters. (For
complete information, see the MAX Reference Guide.)
T1 signalling mode
A T1 line’s signalling mode (Sig Mode) can be one of the following:
•
Inband, robbed bit signalling—The MultiVoice Gateway uses the Rob Ctrl parameter for
the Call Control mechanism.
•
ISDN signalling—Designate the 24th channel of the T1 line as the D channel.
