The LIF SC module offers the serial legacy interfaces V.35, V.36 and
X.21; interfaces used for providing synchronous leased line services.
The module is self-configurable to each of the three interfaces, and by
connecting different cable adapters to the module’s universal serial
communications the three interfaces are provided.
For all legacy interfaces, the unit will act as a DCE unit.
