Setting the Inband Signaling Protocol for E1
11-4 PortMaster Configuration Guide
Setting the Inband Signaling Protocol for E1
Although PortMasters do not require dial digits (the calling number and caller ID) when
establishing a connection, most Telcos transmit this information by default. You can use
the r2gen signalling option if you don’t require dial digits, but you must first arrange for
the Telco not to transmit these signals.
The PortMaster defaults to r2gen when you set the line to inband (see “Configuring
Line Use” on page 11-2).
To accept caller ID and dial digit tones, use the mrf2 option. Because some countries
implement different variations of multi-frequency robbed-bit signalling (MFR2), you
must specify a profile with the mfr2 option.
To set the inband signaling protocol and the inband call options used with channelized
E1, use the following command.
Command> set Line0 signaling mfr2 r2gen|Profile
Table 11-4 explains the inband signaling protocol options and profiles.
