4.2
4.2.1
• The TRANSIU controls up to 24 layer-1 channels via up to three VIP/ VIP8 connected
• IOM-2000 interface: all channels may be programmed in the TRANSIU to:
– U
– S/T interface in LT-S (subscriber master) or LT-T (trunk slave) mode
Note: The number of S/T interfaces in VIP PEB 20590 is limited to 4. Therefore it is
• Data rates: 3.072 Mbit/s (1 VIP), 6.144 Mbit/s (2 VIPs) or 9.216 Mbit/s (3 VIPs)
• Data and maintenance bit handling for S/T and U
4.2.2
Reset Status
• All IOM-2000 channels are configured to S/T interface, LT-S mode
• The data rate in the TRANSIU is set to 3.072 Mbit/s
• All buffers related to the IOM-2000 are undefined
• The Command and Status buffers have the value ‘0’
Channel Programming
Every IOM-2000 channel may be configured in the TRANSIU as:
• U
• S/T channel in LT-S mode
• S/T channel in LT-T mode
Data Rate Programming
The TRANSIU supports three configurations regarding the number of VIPs connected
via IOM-2000:
• One VIP connected at data rate of 3.072 Mbit/s: 8 IOM-2000 channels at a clock rate
• Two VIPs connected at data rate of 6.144 Mbit/s: 16 IOM-2000 channels at a clock
• Three VIPs connected at data rate of 9.216 Mbit/s: 24 IOM-2000 channels at a clock
