3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
Receive ATM Cell – Insertion/Extraction Memory Register – Byte 3 (Address = 0xN714)
Note:
STEP 3b – Read the contents of the second byte (of this new ATM cell) from the Receive ATM Cell –
Insertion/Extraction Memory Register – Byte 2; as depicted below.
Receive ATM Cell – Insertion/Extraction Memory Register – Byte 2 (Address = 0xN715)
Note:
STEP 3c – Read the contents of the third byte (of this new ATM cell) from the Receive ATM Cell –
Insertion/Extraction Memory Register – Byte 1; as depicted below.
Receive ATM Cell – Insertion/Extraction Memory Register – Byte 2 (Address = 0xN716)
Note:
STEP 3d – Read the contents of the fourth byte (of this new ATM cell) from the Receive ATM Cell –
Insertion/Extraction Memory Register – Byte 0; as depicted below.
Receive ATM Cell – Insertion/Extraction Memory Register – Byte 2 (Address = 0xN717)
Note:
STEP 4 – Continue to read out the contents of the remaining bytes of this ATM cell from the “Receive
Cell Extraction Memory”.
This is accomplished by executing the procedure, outlined in STEP 3, repeatedly for 13 more times.
