Overview

Handling of Layer-1 Functions

• Change detection for C/I-channel (IOM-configuration) or feature control

(SLD-configuration)

• Double last-look logic for C/I-channel (IOM-2 analog configuration)

• Additional last-look logic for feature control (SLD-configuration)

• Buffered monitor (IOM-configuration) or signaling channel (SLD-configuration)

Bus Interface

• Siemens/Intel or Motorola type µP-interface

• 8-bit demultiplexed bus interface

• FIFO-access interrupt or DMA controlled
