4.3.1
The IOMU provides the DSP access to incoming time slots from the IOM-2 interface. The
DSP may switch the timeslots to the other DELIC system interfaces.
Features
• DSP access for switching of B1 and B2 data to the PCMU and the TRANSIU
• DSP access for extracting of D-channel information
• DSP access for control of IOM-2 Command/Indication (C/I) and Monitor channel
Interface Configuration
• Two IOM-2 ports providing up to 16 IOM-2 channels (up to 16 ISDN or 32 analog
• Available data rate modes:
– Two ports of 384 kbit/s each (2 x 6 time slots per frame)
– Two ports of 768 kbit/s each (2 x 12 time slots per frame)
– Two ports of 2.048 Mbit/s each (2 x 32 time slots per frame)
– One port of 4.096 Mbit/s (1 x 64 time slots per frame)
• Single or double data rate clock selectable in each data rate mode
• Programmable tri-state control for each port and channel (=4 time slots)
• Push-pull or open-drain configuration
• DRDY signal for D-channel control when connected to QUAT-S PEB 2084
(providing a constant switching delay of two 8 kHz frames)
