The IOM-2000 interface represents a new concept for connecting ISDN layer-1 devices
to the DELIC. The transceiver unit (TRANSIU) and the DSP perform the layer-1 protocol,
which enables flexible and efficient operation of the transceiver IC (VIP/ VIP8).
VIP/ VIP8 supports two types of ISDN interfaces: 2-wire (ping-pong) U
4-wire S/T interfaces. For detailed description please refer to VIP/ VIP8 Data Sheet.
The IOM-2000 interface consists of the following signals:
• Frame Synchronization: IOM-2000 uses the same 8 kHz FSC as the IOM-2 ports.
• Data Interface: Data is transmitted via DX line from DELIC to VIP with DCL_2000
• Command/Status Interface: Configuration and control information of VIP’s layer-1
• Data/Command Clock: Data and commands for one VIP are transmitted at
• Reference Clock: In LT-T mode, the VIP provides a reference clock synchronized to
