| XRT86SH328 28-CHANNEL SONET/SDH VT MAPPER REGISTER DESCRIPTION WITH M13 AUG 2008 REV. 1.0.1 GENERAL DESCRIPTION The XRT86SH328 is an integrated VT/TU Mapper with 28 port T1/E1 Line Interface Units. The XRT86SH328 contains integrated DS1/E1/J1 Framers for performance monitoring. The XRT86SH328 processes the Section, Line and Path overhead in the SONET/SDH data-stream. The processing of path overhead bytes within the STS-1s or TUG-3s include 64 bytes (of buffer) for storing the (Section Trace and Path Trace) messages. Path Overhead bytes can be accessed either by on-chip registers or a Serial Output Port. Each of the 28 T1 or E1 Channels use an internal DeSynchronizer circuit with an internal pointer leak algorithm. This removes the jitter due to mapping and pointer adjustments from the T1 or E1 signals that are de-mapped from the incoming SONET/SDH datastream. These De-Synchronizer circuits do not need any external clock references for its operation. The Transmit Blocks permit flexible insertion of TOH and POH bytes via both Hardware and Software control. The Receive Blocks receive a SONET STS-1 signals or an SDH STM-1 signal and performs the necessary Transport and Path Overhead Processing. A PRBS Pattern Generator and Receiver is implemented within each of the 28 T1/E1 channels in order to implement and measure Bit-Error performance. A general purpose Microprocessor Interface is included for control, configuration and monitoring. FEATURES * Supports 21 E1 mapped as Asynchronous VT2 into an STS-1 SPE or TU-12 tributary units into STM-1/VC-3 or TUG-3 from a STM-1/VC-4. * Supports TU cross-mapping function TU-12/VC-11/T1. * Supports mixed mapping of VT-G/VT1.5 and VT-G/VT2. * Supports mixed mapping of TUG-2/TU-11 and TUG-2/ TU-12 * 28 VT1.5/TU-11 or 21 VT-2/TU-12 tributaries can be passed as transparent between SONET/SDH Telecom Bus on the line side and Clock and Data on the system side. * Supports Unframed T1/E1 signals * Supports DS1/E1 Performance Monitoring in both Egress and Ingress direction * VC-11/VC-12 Tandem Connection Monitoring support * Complies with the Category I Intrinsic Jitter Requirements for DS1 signals being de-mapped from SONET, per Telcordia GR-253-CORE * Complies * Complies with the "Mapping Jitter Generation Specification" for DS1 and E1 signals being de-mapped from SDH, per ITU-T G.783 with the "Combined Jitter Generation Specification" for DS1 and E1 signals being de-mapped from SDH, per ITU-T G.783 * Line and Facility Loop-backs * Each of the 28 T1/E1 Channels Generator and Receiver. includes a PRBS * Each of the 28 VT-Mapper blocks are capable of generating BIP-2 and REI errors upon software command (for diagnostic purposes). both the M13(M23) and the C-bit Parity Framing formats. * *The Transmit and Receive DS3 Framer blocks support * Integrated 28 T1/E1/J1 Short-Haul Line Interface Units * IEEE 1149.1 Standard Boundary Scan * Low Power: 1.8V Power Supply for Core Logic; 3.3V Power Supply for I/O * Provides mapping of up to 28 T1 streams as Asynchronous VT1.5 into an STS-1 SPE or TU-11 tributary unit into an STM-1/VC-3 or TUG-3 from STM-1/ VC-4 28 T1 streams M13 multiplexed into a serial DS3 * Supports * Supports * General Purpose Microprocessor Interface APPLICATIONS 21 E1 streams M13 multiplexed into a serial DS3 (compliant with ITU-T G.747) asynchronously mapped into STS-1. * 28 T1 Streams M13 Multiplexed into a DS3 and DS3 is * 21 E1 Streams M13 Multiplexed into a DS3 (ITU-T G.747) and DS3 is asynchronously mapped into STS-1. * Channelized and Unchannelized DS3 applications * T1/E1 Terminals * SONET/SDH ADM Exar Corporation 48720 Kato Road, Fremont CA, 94538 * (510) 668-7000 * FAX (510) 668-7017 * www.exar.com XRT86SH328 28-CHANNEL SONET/SDH VT MAPPER REGISTER DESCRIPTION WITH M13 FIGURE 1.

The actual location of the SPE will NOT be adjusted, per the value of H1 and H2 bytes. Hence, this feature should cause the remote terminal to declare an Invalid Pointer condition. 0 - Configures the Transmit STS-1/STS-3 POH and TOH Processors to transmit STS-1 or STS-3 Data with normal and correct H1 and H2 bytes. 1 - Configures the Transmit STS-1/STS-3 POH and TOH Processor blocks to overwrite the values of the H1 and H2 bytes (in the outbound STS-1 or STS-3 Data-stream) with the values in the Transmit STS-1/STS-3 POH Arbitrary H1 and H2 Pointer registers. BITt 4 - Check Stuff Monitoring This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 POH and TOH Processor blocks to only execute a Positive, Negative or NDF event (via the Insert Positive Stuff, Insert Negative Stuff, Insert Continuous or Single NDF options, via software command) if no pointer adjustment (NDF or otherwise) has occurred during the last 3 STS-1/STS-3 frame periods. 0 - Disables this feature.In this mode, the Transmit STS-1/STS-3 POH and TOH Processor block will execute a software-commanded pointer adjustment event, independent of whether a pointer adjustment event has occurred in the last 3 STS-1/STS-3 frame periods. 1 - Enables this feature.In this mode, the Transmit STS-1/STS-3 POH and TOH Processor block will ONLY execute a software-commanded pointer adjustment event, if no pointer adjustment event has occurred during the last 3 STS1/STS-3 frame periods. BITt 3 - Insert Negative Stuf This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 POH and TOH Processor blocks to insert a negative-stuff into the outbound STS-1 or STS-3 Data stream. This command, in-turn will cause a Pointer Decrementing event at the remote terminal. Writing a 0 to 1 transition into this bit-field causes the following to happen. * * * A negative-stuff will occur (e.g., a single payload byte will be inserted into the H3 byte position within the outbound STS-1 or STS-3 Data stream). The D bits, within the H1 and H2 bytes will be inverted (to denote a Decrementing Pointer Adjustment event). The contents of the H1 and H2 bytes will be decremented by 1, and will be used as the new pointer from this point on. NOTE: Once the user writes a 1 into this bit-field, the XRT86SH328 will automatically clear this bit-field. Hence, there is no need to subsequently reset this bit-field to 0. BITt 2 - Insert Positive Stuff This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 POH and TOH Processor blocks to insert a positive-stuff into the outbound STS-1 or STS-3 Data stream.

BITt 1 - Insert Continuous NDF Events This READ/WRITE bit-field is used configure the Transmit STS-1/STS-3 POH and TOH Processor blocks to continuously insert a New Data Flag (NDF) pointer adjustment into the outbound STS-1 or STS-3 Data stream. As the Transmit STS-1/STS-3 POH and TOH Processor blocks insert the NDF event into the STS-1 or STS-3 Data stream, it will proceed to load in the contents of the Transmit STS-1/STS-3 POH Arbitrary H1 Pointer and Transmit STS1/STS-3 POH Arbitrary H2 Pointer registers into the H1 and H2 bytes (within the outbound STS-1 or STS-3 Data stream). 0 - Configures the Transmit STS-1/STS-3 TOH and POH Processor blocks to not continuously insert NDF events into the outbound STS-1 or STS-3 Data stream. 1- Configures the Transmit STS-1/STS-3 TOH and POH Processor blocks to continuously insert NDF events into the outbound STS-1 or STS-3 Data stream. BITt 0 - Insert Single NDF Event This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 POH and TOH Processor blocks to insert a New Data Flag (NDF) pointer adjustment into the outbound STS-1 or STS-3 Data stream.

NOTE: Afterwards, the N bits will resume their normal value of 0110 and this new pointer value will be used as the new pointer from this point on. Once the user writes a 1 into this bit-field, the XRT86SH328 will automatically clear this bit-field. Hence, there is no need to subsequently reset this bit-field to 0.

BIT 4 - Transmit LOS Pattern Select: This READ/WRITE bit-field is used to configure the Transmit DS3 Framer block to transmit either an All Zeros or an All Ones pattern, anytime it is configured to transmit the LOS Pattern to the remote terminal equipment, as described below. 0 - Configures the Transmit DS3 Framer block to transmit an All Zeros pattern whenever it is configured to transmit the LOS pattern. 1 - Configures the Transmit DS3 Framer block to transmit an All Ones pattern whenever it is configured to transmit the LOS pattern. BIT[3:0] - Transmit DS3 Idle Pattern[3:0] These READ/WRITE bit-fields are used to specify the type of framed, repetitive four-bit pattern that the Transmit DES3 Framer block should generate and transmit, whenever it is configured to transmit the DS3 Idle Pattern. NOTE: Setting these bit-fields to [1, 1, 0, 0] configures the Transmit DS3 Framer block to transmit the standard Framed, repeating 1, 1, 0, 0, ... pattern (per Bellcore GR-499-CORE) requirements.
