3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
This step configures the Transmit UTOPIA Address, of the value [C4, C3, C2, C1, C0] to be assigned to STS-
3c Channel 2.
Notes:
Once the user has executed STEPS 3a and 3b then STS-3c Channel 2 within the XRT94L33 has been
assigned the “Transmit UTOPIA Address” of [c4, c3, c2, c1, c0].
STEP 4 – Assign a “Transmit UTOPIA Address” to STS-3c Channel 3
The user can accomplish this by doing the following.
STEP 4a – Set Bits 0 through 4 (“Tx_UTOPIA_Port_Number[4:0]”) within the “Transmit UTOPIA Port
Number Register” to “0x03”; as depicted below.
Transmit UTOPIA Port Number Register (Address = 0x0597)
This step configures an internal “Transmit UTOPIA Address assignment” pointer to point to “STS-3c Channel
3” within the XRT94L33.
STEP 4b – Set Bits 0 through 4 (“Tx_UTOPIA_Addr[4:0]”) within the “Transmit UTOPIA Address”
Register to the “Multi-PHY” Address value for this channel [d4, d3, d2, d1, d0]; as depicted below.
Transmit UTOPIA Address Register (Address = 0x0593)
This step configures the Transmit UTOPIA Address, of the value [D4, D3, D2, D1, D0] to be assigned to STS-
3c Channel 3.
Notes:
Once the user has executed STEPS 4a and 4b then STS-3c Channel 3 within the XRT94L33 has been
assigned the “Transmit UTOPIA Address” of [d4, d3, d2, d1, d0].

During this step, the user can write in any value, between 0x00 and 0x1E, provided this “Multi-PHY Address” is
unique among all of the Transmit UTOPIA Interface addresses within a “Multi-PHY” system.
Use of the value “0x1F” is NOT permitted.
These steps do not assign a Receive UTOPIA Address value to STS-3c Channel 2. This assignment must be
performed separately per the “Receive UTOPIA Address Assignment” instructions presented in Section _.
