Frequency Plan; System Features - Nortel Internet BWA System 3200 User Manual

1-2 System description
For systems with a specific capacity (for example, a 4 x E1 capacity), the
activation of a new tributary within that capacity is software programmable,
either locally or remotely. The activation of a new tributary within an existing
capacity does not cause any errors to the existing traffic. Inactive tributaries do
not cause alarms.
