Assigning Channel Functions
Unless you change the default channel function, each E1 channel on an interface
is idle by default.
You can assign these functions:
• Data -- Assigns the channel to data pass-through (E1 connector to
E1 connector)
• Voice -- Assigns the channel to voice pass-through (E1 connector to
E1 connector)
• Circuit 1 -- Assigns the channel to the first E1 connector
• Circuit 2 -- Assigns the channel to the second E1 connector
• Idle -- Makes the channel idle
Circuit Assignment
You cannot allocate an E1 channel to more than one E1 circuit. For example, if
you allocate Channels 17 to 25 to Circuit 1 on the first E1 connector, you must
make these channels idle or allocate them to Circuit 2 on the second E1 connector.
Data and Voice Pass-Through
To enable data and voice pass-through, assign identical channels to data or voice
on both E1 connectors.
For example, if the first E1 connector allocates Channels 2 to 8 to voice
pass-through and Channels 9 to 16 to data pass-through, the second E1 connector
must also allocate Channels 2 to 8 to voice pass-through, and Channels 9 to 16 to
data pass-through.
You can assign a specific function to E1 channels.
