`SUPPLEMENT TO 802.3:
`
`the PMA performs a conversion from NRZI format and generates a PMA _ UNIIDATA.indicate (rx _code-bit)
`primitive with the same logical value for the rx _code-bit parameter.
`
`24.3.4.3 Carrier detect
`
`The PMA Carrier Detect process provides repeater clients an indication that a carrier event has been sensed
`and an indication if it is deemed in error. A carrier event is defined as receipt of two non-contiguous ZEROS
`within any 10 rx_code-bits. A carrier event is in error if it does not start with an SSD. The Carrier Detect pro(cid:173)
`cess performs this function by continuously monitoring the code-bits being delivered by the RX process, and
`checks for specific patterns which indicate non-IDLE activity and SSD bit patterns.
`
`The Carrier Detect process collects code-bits from the PMD RX process. r_bits [9:0] represents a sliding,
`10-bit window on the code-bit sequence, with newly received code-bits from the RX process being shifted
`into r_bits [0]. The process shifts the r_bits vector to the left, inserts the newly received code-bit into posi(cid:173)
`tion 0, and waits for the next PMD.UNITDATA.indicate before repeating the operation. This is depicted in
`figure 24-13. The Carrier Detect process monitors the r _bits vector until it detects two noncontiguous
`ZEROS in the incoming code-bit sequence. This signals a transition of carrier_status from OFF to ON. Each
`new carrier is further examined for a leading SSD (1100010001) with rxerror_status set to ERROR if it is
`not confirmed. A pattern of 10 contiguous ONEs in the stream indicates a return to carrier_status =OFF.
`Code-bit patterns of contiguous ONEs correspond to IDLE code-groups in the PCS, per the encoding speci(cid:173)
`fied in 24.2.2.1.

`
`The PMA shall, if it is supporting a repeater, implement the Carrier Detect process as depicted in figure 24-
`14 including compliance with the associated state variables as specified in 24.3.3.
`
`24.3.4.4 Link Monitor
`
`The Link Monitor process is responsible for determining whether the underlying receive channel is provid(cid:173)
`ing reliable data. Failure of the underlying channel typically causes the PMA's client to suspend normal
`actions. The Link Monitor process takes advantage of the PMD sub layer's continuously signaled transmis(cid:173)
`sion scheme, which provides the PMA with a continuous indication of signal detection on the cl1a1mel
`through signal_status as communicated by the PMD_SIGNAL.indicate primitive. It responds to control by
`link_control parameter of
`Auto-Negotiation, when implemented, which is effected through the
`PMA _SIGNAL request.
`
`The Link Monitor process monitors signal_status, setting link_status to FAIL whenever signal_status is OFF
`or when Auto-Negotiation sets link _control to DISABLE. The link is deemed to be reliably operating when
`signal_status has been continuously ON for a period of time. This period is implementation dependent but
`not less than 330 JlS or greater than 1000 JlS. If so qualified, Link Monitor sets link_status to READY in
`order to synchronize with Auto-Negotiation, when implemented. Auto-Negotiation permits full operation by
`setting link_control to ENABLE. When Auto-Negotiation is not implemented, Link Monitor operates with
`link_control always set to ENABLE.

`24.4.1.1.3 Effect of receipt
`
`IEEE
`Std 802.3u-1995
`
`Upon receipt of this primitive, the PMD corwerts the specified nrzi-bit into the appropriate signals on the
`MDI.
`

`24.4.1.2.1 Semantics of the service primitive
`
`PMD_UNIIDATA.indicate (rx_nrzi-bit)
`
`The data conveyed by PMD _UNIIDATA.indicate is a continuous nrzi-bit sequence. The rx_nrzi-bit param(cid:173)
`eter can take one of two values: ONE or ZERO.
`
`24.4.1.2.2 When generated
`
`The PMD continuously sends nrzi-bits to the PMA corresponding to the signals received from the MDI.
`
`24.4.1.2.3 Effect of receipt
`
`The effect of receipt of this primitive by the client is unspecified by the PMD sub layer.
`
`24.4.1.3 PMD_SIGNAL.indicate
`
`This primitive is generated by the PMD to indicate the status of the signal being received from the MDI.
`
`24.4.1.3.1 Semantics of the service primitive
`
`PMD _SIGNAL.indicate (signal_ status)
`
`The signal_status parameter can take on one of two values: ON or OFF, indicating whether the quality and
`level of the received signal is satisfactory (ON) or unsatisfactory (OFF). When signal_status = OFF, then
`rx_nrzi-bit is undefined, but consequent actions based on PMD _SIGNAL.indicate, where necessary, inter(cid:173)

`
`24.5 Compatibility considerations
`
`SUPPLEMENT TO 802.3:
`
`There is no requirement for a compliant device to implement or expose any of the interfaces specified for the
`PCS, PMA, or PMD. However, if an exposed interface is provided to the PCS, it shall comply with the
`requirements for the Mil, as specified in clause 22.
`
`24.6 Delay constraints
`
`Proper operation of a CSMA/CD LAN demands that there be an upper bound on the propagation delays
`through the network. This implies that MAC, PHY, and repeater implementors must conform to certain delay
`minima and maxima, and that network planners and administrators conform to constraints regarding the
`cable topology and concatenation of devices. MAC constraints are contained in clause 21. Topological con(cid:173)
`straints are contained in clause 29.
`
`The reference point for all ~IDI measurements is the 50% point of the mid-cell transition corresponding to
`the reference code-bit, as measured at the l\IIDI. Although IOOBASE-TX output is scrambled, it is assumed
`that these measurements are made via apparatuses that appropriately account for this.
`
`24.6.1 PHY delay constraints (exposed Mil)
`
`Every IOOBASE-X PHY with an exposed Mil shall comply with the bit delay constraints specified in table
`24-2. These figures apply for alllOOBASE-X PMDs.

`25. Physical Medium Dependent (PMD) sublayer and baseband medium, type
`100BASE-TX
`
`25.1 Overview
`
`This clause specifies the 100BASE-X PMD (including MDI) and baseband medium for twisted-pair wir(cid:173)
`ing, lOOBASE-TX. In order to form a complete 100BASE-TX Physical Layer it shall be integrated with
`the lOOBASE-X PCS and PMA of clause 24, which are assumed incorporated by reference. As such, the
`100BASE-TX PMD shall comply with the PMD service interface specified in 24.4.1.
`
`25.2 Functional specifications
`
`The lOOBASE-TX PMD (and MDI) is specified by incorporating the FDDI TP-PMD standard, ANSI
`X3.263: 199X (TP-PMD), by reference, with the modifications noted below. This standard provides sup(cid:173)
`port for Category 5 unshielded twisted pair (UTP) and shielded twisted pair (STP). For improved legibil(cid:173)
`ity in this clause, ANSI X3.263: 199X (TP-PMD), will henceforth be referred to as TP-PMD.
`
`25.3 General exceptions
`
`The 100BASE-TX PMD is precisely the PMD specified as TP-PMD, with the following general modifications:
`
`a)
`
`The Scope and General description discussed in TP-PMD 1 and 5 relate to the use of those standards
`with anFDDI PHY, ISO 9314-1: 1989, and MAC, ISO 9314-2: 1989. These sections are not relevant
`to the use of the PMD with lOOBASE-X.
`b) The Normative references, Definitions and Conventions ofTP-PMD 2, 3, and 4 are used only as nec(cid:173)
`essary to interpret the applicable sections ofTP-PMD referenced in this clause.
`The PMD Service Specifications of TP-PMD 6 are replaced by those specified in 24.4.1. The
`100BASE-TX PMD Service specification is a proper subset of the PMD Service Specification in
`TP-PMD.
`There are minor terminology differences between this standard and TP-PMD that do not cause ambi(cid:173)
`guity. The terminology used in 100BASE-X was chosen to be consistent with other IEEE 802 stan(cid:173)
`dards, rather than with FDDI. Terminology is both defined and consistent within each standard.
`Special note should be made of the interpretations shown in table 25-1.

`25.4 Specific requirements and exceptions
`
`The lOOBASE-TX PMD (including MDI) and baseband medium shall comply to the requirements of
`TP-PMD, 7, 8, 9, 10, and 11, and normative annexA with the exceptions listed below. In TP-P"NID, infor(cid:173)
`mative annexes B, C, E, F, G, I, and J, with exceptions listed below, provide additional information useful
`to PMD sublayer implementors. Where there is conflict between specification in TP-PMD and those in
`tllis standard, those of tllis standard shall prevail.
`
`25.4.1 Change to 7.2.3.1.1, "Line state patterns"
`
`Descrambler synchronization on the Quiet Line State (QLS), Halt Line State (HLS), and Master Line
`State (MLS) Line State Patterns cited in TP-PMD 7.2.3.1.1 is optional.
`
`25.4.2 Change to 7.2.3.3, "Loss of synchronization"
`
`The synchronization error triggered by PH_Invalid as defined in TP-PMD 7.2.3.3a is not applicable.
`
`25.4.3 Change to table 8-1, "Contact assignments for unshielded twisted pair"
`
`1 OOBASE-TX for unshielded twisted pair adopts the contact assignments of lOBASE-T. Therefore, the
`contact assignments shown in TP-PMD table 8-1 shall instead be as depicted in table 25-2.
`
`25.4.4 Deletion of 8.3, "Station labelling"
`
`Clause fU ofTP-PMD shall not be applied to lOOBASE-TX.
`
`25.4.5 Change to 9.1.9, "Jitter"
`
`The jitter measurement specified in 9 .1.9 of TP-PJVID may be performed using scrambled IDLEs.

`25.4.6 Replacement of 11.2, "Crossover function"
`
`Clause 11.2 of TP-PMD is replaced with the following:
`
`A crossover function compliant with 14.5.2 shall be implemented except that a) the signal names are those
`used in TP-PMD, and b) the contact assignments for STP are those shown in table 8-2 ofTP-PMD. Note
`that compliance with 14.5.2 implies a recommendation that crossover (for both UTP and STP) be per(cid:173)
`formed within repeater PHY s.
`
`25.4.7 Change to A.2, "DDJ test pattern for baseline wander measurements"
`
`The length of the test pattern specified in TP-PMD annex A.2 may be shortened to accommodate feasible
`100BASE-X measurements, but shall not be shorter than 3000 code-groups.
`
`NOTE-This pattern is to be applied to the MII. (When applied to the MAC, the nibbles within each byte are to be
`swapped. E.g., as delivered to the MAC, the test pattern would start, "60 c9 16 ... ".)
`
`25.4.8 Change to annex G, "Stream cipher scrambling function"
`
`An example of a stream cipher scrambling implementation is shown in TP-PMD annex G. This may be
`modified to allow synchronization solely on the IDLE sequences between packets.
`
`25.4.9 Change to annex I, "Common mode cable termination"
`
`The contact assignments shown in TP-PMD figures 1-1 and 1-2 shall instead comply with those specified
`in table 25-2.

`26. Physical Medium Dependent (PMD) sublayer and baseband medium, type
`100BASE-FX
`
`26.1 Overview
`
`This clause specifies the lOOBASE-X PMD (including MDI) and fiber optic medium for multi-mode fiber,
`lOOBASE-FX. In order to form a complete lOOBASE-FX Physical Layer it shall be integrated with the
`lOOBASE-X PCS and PMA of clause 24, which are assumed incorporated by reference. As such, the
`lOOBASE-FX PMD shall comply with the PMD service interface specified in 24.4.1.
`
`26.2 Functional specifications
`
`The lOOBASE-FX PMD (and MDI) is specified by incorporating the FDDI PMD standard, ISO 9314-3:
`1990, by reference, with the modifications noted below. This standard provides support for two optical
`fibers. For improved legibility in this clause, ISO 9314-3: 1990 will henceforth be referred to as
`fiber-PMD.
`
`26.3 General exceptions
`
`The lOOBASE-FX PMD is precisely the PMD specified as fibcr-PMD, with the following general modifi(cid:173)
`cations:
`
`a)
`
`The Scope and General description discussed in fiber-PMD 1 and 5 relate to the use of those stan(cid:173)
`dards with an FDDI PHY, ISO 9314-1: 1989, and MAC, ISO 9314-2: 1989. These clauses are not
`relevant to the use of the PMD with lOOBASE-X.
`b) The Normative references, Definitions and Con:ventions of fiber-PMD 2, 3, and 4 are used only as
`necessary to interpret the applicable sections offiber-PMD referenced in this clause.
`The PMD Service Specifications of fiber-PMD 6 are replaced by those specified in 24.4.1. The
`lOOBASE-FX PMD Service specification is a proper subset of the PMD service specification in
`fiber-PMD.
`There are minor terminology differences between this standard and fiber-PJVID that do not cause
`ambiguity. The terminology used in lOOBASE-X was chosen to be consistent with other IEEE 802
`standards, rather than with FDDI. Terminology is both defined and consistent within each standard.
`Special note should be made of the interpretations shown in table 26-1.
