RISC Microcode from RAM
This controller only performs the lowest layers of the SS7 protocol stack. The upper layers
must be performed in software by the CPU in the system. The software to perform the upper
layer protocol is available from third party providers.
The SS7 controller contains the following key features:
C.1.1 Performance
At 25Mhz, an aggregate SS7 bandwidth of 6 Mbps divided among the 4 SCCs consumes
100% of the processing power of the RISC communications engine. If only a percentage of
the total available SS7.
bandwidth is used, the remaining RISC processing power can be used to run other protocols
on other channels. Table C-1 shows possible QUICC configurations.
C-2
• Uses either NMSI or TDM interface and a variety of data encoding schemes.
• Flexible data buffers with multiple buffers per signal unit allowed.
• Separate interrupts for received signal units and transmitted buffers.
• Maintenance of good frame counter, bad frame counter, and SU Error Monitor.
• Standard HDLC features:
—Flag/Abort/Idle generation/detection
—Zero insertion/deletion
—16-bit CRC-CCITT generation/checking
—Detection of non-octet aligned signal units
—Programmable number of flags between signal units
—Detection of long SUs.
—Discard short (less than 5 octets) signal units.
—Automatic Fill-In Signal Unit transmission.
—Automatic Link Status Signal Unit retransmission.
—Automatic discard of identical FISUs and LSSUs.
—Octet Counting Mode support.
—Command to force a reset of filtering state.
—Command to force entry into octet counting mode.
—Ability to permanently disable octet counting mode.
—Ability to disable FISU and LSSU filtering.
—Ability to force entry into octet counting mode if a receiver overrun occurs.
—Consumes 1280 bytes of the QUICC’s internal memory.
