XRT86SH328 VOYAGER - E1 FRAMER + LIU REGISTER DESCRIPTION AUGUST 2008 REV. 1.0.1 GENERAL DESCRIPTION The XRT86SH328 has a total of 42 independent E1 framers (or 56 independent framers for T1). This Voyager Device maps 21 E1 payloads up to STS-3/ STM-1. The purpose of the 42 framers is to allow back-to-back transmit and receive framers on each of the 21 channel Egress and Ingress data paths. The channel numbering system references the framers according to the block diagram shown in Figure 1, where every 4TH Channel is not used in E1 mode. The XRT86SH328 provides E1 framing and error accumulation in accordance with ANSI/ITU_T specifications. Each framer has its own framing synchronizer and transmit-receive slip buffers. The slip buffers can be independently enabled or disabled as required and can be configured to frame to the common E1 signal formats. Each Framer block contains its own Transmit and Receive E1 Framing function. There is 1 Transmit HDLC controller per channel which encapsulates contents of the Transmit HDLC buffers into LAPD Message frames. There is 1 Receive HDLC controller per channel which extracts the payload content of Receive LAPD Message frames from the incoming E1 data stream and write the contents into the Receive HDLC buffers. The XRT86SH328 fully meets all of the latest E1 specifications: ANSI E1.107-1988, ANSI E1.4031995, ANSI E1.231-1993, ANSI E1.408-1990, AT&T TR 62411 (12-90) TR54016, and ITU G-703, G.704, G706 and G.733, AT&T Pub. 43801, and ETS 300 011, 300 233, JT G.703, JT G.704, JT G706, I.431. Extensive test and diagnostic functions include Loopbacks, Boundary scan, Pseudo Random bit sequence (PRBS) test pattern generation, Performance Monitor, Bit Error Rate (BER) meter, forced error insertion, and LAPD unchannelized data payload processing according to ITU-T standard Q.921.

I/O ADDRESSING In order to support E1 and/or T1 multiple channel implementation, maintain rich user controlled features, and provide seamless scalability without sacrificing performance for microcontroller access, Voyager E1 operation chooses an addressing scheme to channelize the access for the microcontroller interface. This mapping order and scheme was chosen such that Voyager E1 channel operation is seamless and consistent with its Voyager T1 channel operation, Voyager XRT86SH328 also supports DS1, DS-3, M13 Mux, STS-1/STS-3 SONET Framer/VT Mapper and many other features.

The Receive E1 Framer block will check for CRC Multiframe Alignment by checking the incoming E1 data-stream and determining whether the international bits (bit 1 of timeslot 0) of non-FAS frames match the CRC multiframe alignment pattern (0,0,1,0,1,1,E1,E2). The table below provides more details on the three different CRC Multiframe Alignment Declaration Criteria. CRC MF ALIGN SEL [1:0] CRC MULTIFRAME ALIGNMENT DECLARATION CRITERIA SELECTED 00 CRC Multiframe Alignment is Disabled 01 CRC Multiframe Alignment is Enabled. Alignment is declared if at least 1 valid CRC multiframe alignment signal (0,0,1,0,1,1,E1,E2) is observed within 8ms. 10 CRC Multiframe Alignment is Enabled. Alignment is declared if at least 2 valid CRC multiframe alignment signals (0,0,1,0,1,1,E1,E2) are observed within 8ms. 11 CRC Multiframe Alignment is Enabled. Alignment is declared if at least 3 valid CRC multiframe alignment signals (0,0,1,0,1,1,E1,E2) are observed within 8ms.

If the user implements this feature, then the Receive E1 Framer block will perform some more testing on two additional E1 frames, prior to declaring the “FAS Frame Alignment” condition. 0 - Disables this additional FAS frame checking. 1 - Enables this additional FAS frame checking. 16 XRT86SH328 VOYAGER - E1 FRAMER + LIU REGISTER DESCRIPTION REV. 1.0.1 TABLE 6: FRAMING SELECT REGISTER (FSR) HEX ADDRESS: 0XN107 BIT FUNCTION TYPE DEFAULT DESCRIPTION-OPERATION 0 FAS Frame Align Sel R/W 0 FAS Alignment Declaration Algorithm Select This bit specifies which algorithm the Receive E1 Framer block uses in its search for the FAS Alignment. 0 = Selects the FAS Alignment Algorithm 1 1 = Selects the FAS Alignment Algorithm 2 FAS Alignment Algorithm 1 If the Receive E1 Framer block has been configured to use “FAS Alignment Algorithm # 1", then it will acquire FAS alignment by performing the following three steps: Step 1 - The Receive E1 Framer block begins by searching for the correct 7-bit FAS pattern. Go to Step 2 if found. Step 2 - Check if the FAS is absent in the following frame by verifying that bit 2 of the assumed timeslot 0 of the Non-FAS frame is a one. Go back to Step 1 if failed, otherwise, go to step 3. Step 3 - Check if the FAS is present in the assumed timeslot 0 of the third frame. Go back to Step 1 if failed. After the first three steps (if they all passed), the Receive E1 Framer Block will declare FAS in SYNC if Frame Check Sequence (Bit 1 of this register) is disabled. If Frame Check Sequence (Bit 1 of this register) is enabled, then the Receive E1 Framer Block will need to verify the correct frame alignment for an additional two frames. FAS Alignment Algorithm 2 If the Receive E1 Framer block has been configured to support “FAS Alignment Algorithm # 2, then it will perform the following 3 steps in order to acquire and declare FAS Frame Alignment with the incoming E1 datastream. Algorithm 2 is similar to Algorithm 1 but adds a one-frame hold off time after the second step fails. After the second step fails, it waits for the next assumed FAS in the next frame before it begins the new search for the correct FAS pattern. Step 1 - Algorithm 1 begins by searching for the correct 7-bit FAS pattern. Go to Step 2 if found. Step 2 - Check if the FAS is absent in the following frame by verifying that bit 2 of the assumed timeslot 0 of the Non-FAS frame is a one. Go back to Step 4 if failed, otherwise, go to step 3. Step 3 - Check if the FAS is present in the assumed timeslot 0 of the third frame. Go back to Step 1 if failed, otherwise, proceed to check for Frame Check Sequence. Step 4 - Wait for assumed FAS in the next frame, then go back to Step 1 After the first three steps (if they all passed), the Receive E1 Framer Block will declare FAS in SYNC if Frame Check Sequence (Bit 1 of this register) is disabled. If Frame Check Sequence (Bit 1 of this register) is enabled, then the Receive E1 Framer Block will need to verify the correct frame alignment for an additional two frames. 17 XRT86SH328 VOYAGER - E1 FRAMER + LIU REGISTER DESCRIPTION TABLE 7: ALARM GENERATION REGISTER (AGR) BIT FUNCTION REV. 1.0.1 HEX ADDRESS: 0XN108 TYPE DEFAULT DESCRIPTION-OPERATION 7 Transmit AUXP Pattern R/W 0 Transmit Auxiliary (AUXP) Pattern This bit permits the user to command the Transmit E1 Framer block to transmit the AUXP Pattern to the remote terminal equipment, as depicted below. 0 - Configures the Transmit E1 Framer block to NOT transmit the AUXP Pattern (which is an unframed, repeating 1010... pattern). 1 - Configures the Transmit E1 Framer block to transmit the AUXP Pattern.
