32.9 Receive and Transmit Connection Tables
(RCT, TCT)
The connection tables, RCT and TCT, hold channel configuration and temporary
parameters for each receive and transmit channel (AAL type, connection traffic parameters,
BDs' parameters and temporary parameters used during segmentation and reassembly).
The internal connection tables hold parameters for up to 128 channels (channels 0–127). In
extended channel mode, parameters for channels 256 and above are kept in external

Hword Internal receive/transmit CAS routing table extension base. User-defined. Note
that because AAL1 CES does not need the TCT extension, the AAL1 CES
microcode uses this Hword to point to a CAS routing table. Should be 32 byte
aligned. User-defined.
External receive/transmit CAS routing table extension base. User-defined. Note
that because AAL1 CES does not need the TCT extension, the AAL1 CES
microcode uses this word to point to a CAS routing table.
RAM used by the CES microcode. Should be 32 byte aligned. User-defined.
Byte
Outgoing CAS Status Register. See Section 32.10, "Outgoing CAS Status
Register (OCASSR)."
Word
Transmit Cell Temporary base address (64-byte aligned). Points to an external
memory block reserved for partially filled cells (64 octets for each CES
channel). This area is allocated by the user but used by the CP.
Hword Incoming CAS Block Base (depicted in Figure 32-12). Points to dual-port RAM.
Should be 32-byte aligned. User-defined.
Hword Outgoing CAS Block Base (depicted in Figure 32-10). Points to dual-port RAM.
Should be 32-byte aligned. User-defined.
Hword AAL1 Internal Statistics Table Base. Points to dual-port RAM. Should be 16-byte
aligned. User-defined. See Section 32.15, "Internal AAL1 CES Statistics

Hword ALL1 Dummy cell base address. Points to dual-port RAM area contains the
AAL1 dummy cell template (little-endian format). Should be 64-byte aligned.

Hword CES adaptive threshold tables base address. Points to the dual-port RAM area
containing the CES slip control thresholds and the adaptive counter See
Section 32.15, "Internal AAL1 CES Statistics Tables.
