Circuit Assignment
You cannot allocate an E1 channel to more than one E1 circuit. For example, if
you allocate Channels 17 through 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 through 8 to voice
pass-through and Channels 9 through 16 to data pass-through, the second E1
connector must also allocate Channels 2 through 8 to voice pass-through, and
Channels 9 through 16 to data pass-through.
You can assign a specific function to E1 channels.
