2.7 Synchrono us Paylo ad Enve lo pe Map per

(SPEMPR) Features (x24)

■The SPE mapper accepts/delivers TUG-2 data from/to

the VT mapper. The TUG-2 data is mapped/demapped

either to/from an AU-3/STS-1 signal for the North Ameri-

can digital systems or to/from a TUG-3 signal for the ITU-

based systems. Only available for SPEMPR 0—2.

■The SPE mapper accepts/delivers channelized DS3 data

from/to the M13 MUX/deMUX. The DS3 data is mapped/

demapped either to/from an AU-3/STS-1 signal for the

North American digital systems or to/from a TUG-3 signal

for the ITU-based systems. Only available for SPEMPR

3—5.

■The SPE mapper accepts/delivers channelized or

unchannelized DS3 signals at a 44.736 Mbits/s rate from

external I/O. The DS3 signals are mapped/demapped

the same way as the M13 signal described above.

■The SPE mapper accepts/delivers channelized E3 data

from/to the E13 MUX/deMUX. The E3 data is mapped/

demapped either to/from an AU-3/STS-1 signal for the

North American digital systems or to/from a TUG-3 signal

for the ITU-based systems. Only available for SPEMPR

3—5.

unchannelized E3 signals at a 34.368 Mbits/s rate from

external I/O. These E3 signals are mapped/demapped

the same way as the E13 signal described above.

■The SPE mapper has a DS3/E3 loopback circuit placed

to demap and remap a DS3/E3 signal. It is particularly

useful in cases where a DS3/E3 signal, mapped as an

AU-3/STS-1 signal, requires remapping as a TUG-3 sig-

nal or vice versa.

■The SPE mapper supports a path overhead access

channel (POAC). Seven path overhead bytes (J1, C2,

F2, H4, F3, K3, and N1) can be inserted/dropped through

this channel. This channel works as the master , meaning

it provides a clock in both the transmit and receive direc-

tions and POH data can be inserted on the transmit side

or dropped on the receive side.

■Path overhead byte B3 (BIP error) generation/detection

and programmable BIP-8 bit error rate insertion.

■Signal fail and signal degrade indicators available to

report bit error rates above standard provisionable

thresholds.

nations.

■Provides grooming capability for up to 168 (84 receive

plus 84 transmit) DS1/E1 connections between the FRM,

VTMPR, M13/E13, and DS1/E1 DJA. This allows for

cross connect grooming of any block signal port n to any

other signa l por t m on a different block, or on the same

block in the case of a groomed loopback.

■Multicast operation (one to many) is supported for 168

sources and destinations.

■Multirate cross connect allows 16 x 3 E1 signals to/from

E13 modules from/to the framer, VT mapper, and

TPG/TPM.

3 Overvi ew

The SONET/ SDH Hyp ermap per Li te devic e inte grates the

SONET/SDH section, line, path, and tributary termination

functions with M13/E13 multiplex functions and the primary

rate framing function. It interfaces to multiple OC-3/STM-1

optical signals or to an OC-12/STM-4 for terminal or add/

drop applications.

The SONET/ SDH Hyp er map perLi te dev ice pro vides a ver-

satile interface for STS-12/STM-4, STS-3/STM-1, and

STS-1/STM-0 termination applications for point-to-point

scenarios and ring applications.

Mapping flexibility allows for software upgrades from M13/

E13 mapped connections to VT/TU mapped connections.

A single HypermapperLite is capable of processing the

aggregate bandwidth of one STS-12/STM-4 to 12

transMUXed DS3/E3s. Further, a single device can

process the aggregate bandwidth of two STS-12/STSM-4s

terminated to 24 clear-channel DS3/E3s. Additionally, a

single HypermapperLite can function as an STS-12/STS-3/

STM-4/STM-1 add/drop MUX by terminating up to 12

STS-1/STM-0 channels or four AU-4 channels and by

using the internal pointer processors to forward any

nonterminating channels. The device is ideal for other

applications including dual STS-12/STM-4 portless

transMUX, dual STS-3/STM-1 with MSP 1 + 1 protection,

and single-chip STS-12/STM-4 MSP 1 + 1 applications,

among others .

TMXL33625 HypermapperLite

5 Block Description

5.1 TMUX/Clock and Data Recovery (CDR)

Blocks

The TMUX and CDR blocks (four per device) provide the

high-speed interfaces to the SONET/SDH line and

terminate the section and line signals. Several features are

incorporated in these blocks to allow for a variety of system

applications. First, a redundant interface is provided with

the appropriate selectors and bridges to allow easy

implementation of 1:1, 1 + 1, or ring protection schemes.

Second, a separate interface is provided for access to

selected overhead bytes. In SONET applications, the

section DCC-S may be added/dropped at 192 kbits/s, while

SDH applications may use the same I/O for adding/

dropping the DCC-L at 576 kbits/s. Alternately, any bytes in

the entire overhead may be added/dropped. A third feature

of these blocks is that they can operate at both

622.08 Mbits/s or 155.52 Mbits/s, where the 155.52 Mbits/s

mode may use a clock forwarded from the external PHY

device. In this mode, both the receive and transmit

directions of the device may operate asynchronously. In the

622 Mbits/s mode, a CDR is provided for ease of retiming

the data signal. The fourth and final function of these blocks

is to terminate/generate the section, line, and path

overhead (only for the SONET/SDH STS-12/3 or STM-4/1

signals). Automatic generation of AIS/RDI/REI is possible

since the protection path is available on the device.

Additionally, N times filtering is provided for critical bytes

such as K1/K2. All variations in overhead processing

between SONET and SDH are also accommodated. A

summary of the overhead processing follows and includes

the pointer interpretation function necessary for AIS

detection.

5.1.1 Transmit Path Section/Line Overhead

Transmit path section/line overhead is as follows:

■Synchronizing status byte (S1) insertion

■M0/M1 REI-L insertion; automatic insertion may be

inhibited

■K1 and K2 insertion, AIS-L insertion

■B2 calculation and insertion

■F1 byte insertion

■B1 generation and error insertion

■Scrambler

■J0 insert control

■A2 erro r in s er t i on

The entire APS value or K2[2:0] can be inserted via

microprocessor control. Automatic RDI insertion is

supported with individual inhibits for each contributor. A

protection switch selects the RDI-L value for insertion from

the protection board rather than from the working side.

B1 and B2 BIP-8 values are calculated and inserted. Both

values can be inverted.

5.1.2 Receive Path Section/Line Overhead

Receive path section/line overhead is as follows:

■Frame alignment (STS-12/STM-4 or STS-3)

■B1 BIP-8 check

■J0 monitoring

■Descrambling

■F1 monitoring

■B2 BIP-8 check

■APS and K2 monito ri ng

■AIS-L and RDI-L detection

■M1 REI-L detection

■S1 synchronization status monitoring

Framer states and all other state changes are reported.

These cause an interrupt if not masked.

The B1 and B2 parity check supp orts both bit and bloc k

modes. The counters count up to one second’s worth of

BIP errors. These stay at their maximum value in case of

overflow or rollover and should be read (and cleared) at

least once per second.

The J0 monitor supports nonframed, SONET-framed, and

SDH-framed 16-byte sequences, as well as single J0 byte

monitoring modes.

APS monito ring is perform ed on K1[7 :0] and K2[ 7:3] . The

value is stored, and changes are reported. Bits [2:0] of the

K2 byte are monitored independently.

The alarm indication signal (AIS -L /MS -AIS ) and remote

defect indication (RDI-L/MS-RDI) are monitored separately ,

and changes are reported. This information is also sent to

the protection device for ADM applications.

The M1 monitor operates either in bit or block mode and

allows access to the remote error indication

(REI-L/MS-REI) errored bit count.

The S1 by te c an be m oni tored eith er as an entir e 8- bit w ord

or as one 4-bit nibble (bits 7:4).

5 Block Description (continued)

5.1.3 Pointer Interpreter

The TMUX pointer interpreter conforms to ETS 300

417-1-1: January 1996—Annex B.

The pointer interpreter evaluates the current pointer state

for the normal state, path AIS state, or LOP (loss of pointer)

conditions, as well as pointer increments and decrements.

The current pointer state and any changes in pointer

condition are reported to the control system. The number of

consecutive frames for invalid pointer and invalid

concatenation indication is fixed at nine.

5.1.4 Path Termination Function

In STS-3/STM-1 mode, path termination is performed on

either all three STS-1s or on the VC-4. In the

STS-12/STM-4 mode, path termination is performed either

on all twelve STS-1s/four STS-3cs, or on the four VC-4

POH. On the receive side, it includes the following:

■J1 monitoring

■B3 BIP-8 check ing

■C2 signal label monitoring

■REI-P and RDI-P detection

■H4 multiframe monitoring

■F2, F3, and K3 automatic protection switch monitoring

■N1 tandem connection monitoring

■Signal degrade BER and signal fail BER detection

■Path overhead access channel (RPOAC) drop

■AIS-P/HO-AIS insertion

■Automatic AIS generation (with individual inhibit)

The J1 monitor (as found in the TMUX block) provides the

following four modes of operation (16 byte or 64 byte):

■SONET mode

■SDH mode

■User mode

■Single byte mode

Note: For additional J1 functionality, please refer to the

STS1-LT and SPEMPR sections of the Register

Description document.

B3 is monitored either in bit or block mode. Provisionable

N-times detection counters are implemented for C2, F2,

F3, N1, and K3 bytes. The K3 APS byte and N1 TCM byte

can be monitored as an entire 8-bit word or as two 4-bit nib-

bles.

5.2 STS-12/STM-4 Pointer Processor (STSPP)

Block

A pointer processor (four per device) is used to move a

SONET/SDH payload from the line clock domain to the

system clock domain. The HypermapperLite STS-12

pointer processors are SONET and SDH compliant and

offer a configurable STS-3/STM-1 or STS-12/STM-4 mode.

They support an arbitrary mix of STS-1/STS-3c tributaries

and SDH equivalents, and comply with GR-253-CORE,

T1.105, G.707, G.783, G.826, G.821, and ETSI 417-1-1.

5.3 STS-1 Line Terminating (STS1LT) Block

The STS-1 line terminating block (12 per device) allows

termination of an STS-1 line signal routed from the

multirate cross connect. It provides access to the section/

line and path overhead similarly to the TMUX. It can also

source an SPE to the STS cross connect for transport on

the high-speed line interface.

5.4 STS Cross Connect (STSXC) Block

The high-order cross connect block (four per device)

connects the SONET/SDH interfaces to the PDH portion of

the device. It will permit connections that support a variety

of applications. The data paths, clocks, and syncs are

internally configured as appropriate for the different signal

rates and interconnects. A significant portion of the STSXC

block is the mate interconnect described in Section 5.5.

5.5 Mate Interconnect and Clock Data Recovery

(MCDR) Block

The HypermapperLite can be configured to terminate an

STS-12/STM-4 signal by connecting the device partitions

(A, B, C, D) together via the mate interconnect. Each

interconnect operates at 155 Mbits/s and is connected

between a single HypermapperLite partition configured as

master and up to three HypermapperLite partitions with

high-speed TMUX input configured as slaves. The mate

interconnect uses SONET/SDH framing and overhead so

there is performance monit oring of the link between

partitions.

Note: Not all applications require all four partitions to fully

terminate an STS-12/STM-4.

1616 Agere Systems Inc.

5 Block Description (continued)

5.6 SPE/AU-3 Mapper (SPEMPR) Block

The SPE mapper functional block (24 per device) operates

either as an AU-3/STS-1 mapper or as a TUG-3 mapper . In

either mode, it maps/demaps data from/to either the VT

mapper, the M13/E13 MUX/deMUX, the DS3/E3 clear

channel, or the DS3/E3 loopback channel. The SPE

mapper supports numerous automatic monitoring functions

and provides interrupts to the control system, or it can be

operated in a polled mode.

In DS3 mapping mode, the SPE mapper functional block

accepts/delivers structured DS3 data from/to the M13

functional block or a clear channel DS3 signal at

44.736 Mbits/s rate and maps/demaps it asynchronously

to/from the STS-1 SPE or a TU-3. The DS3 mapper

generates a fixed pointer value of 522.

On the receive side, pointer interpretation is performed,

detecting LOP, AIS, NDF, NORM, INC, and DEC. A DS3

loopback mode allows demapping and remapping of a DS3

signal. It is particularly useful in cases where a DS3 signal

mapped as AU-3/STS-1 needs to be remapped as a TU-3

signal or vice versa. B3ZS encoding/decoding is included.

The E3 mapping mode is similar in functionality to that of

the DS3 mapping mode just described.

This functional block also connects to the path overhead

access channel (POAC) to insert/drop path overhead bytes

J1, C2, F2, H4, F3, K3, and N1 into/from the STS-1 SPE or

VC-3.

The SPE mapper functional block complies with GR-253-

CORE, T1.105, ITU-T G.707, ITU-T G.831, G.783, and ETS

300 417-1-1.

5.7 VT/TU Mapper (VTMPR) Block

The VT/TU mapper (12 per device) maps any valid combi-

nation of DS1 and E1 signals into a stream at a rate of

51.84 Mbits/s (STS-1 or AU-3). The mapping methods

(VT1.5, VT2, and VT group in ANSI nomenclature; TU-11,

TU-12, and TUG-2 in ITU nomenclature) are analogous.

The VT/VC mapper supports the following mappings:

■28 asynchronous, byte-, or bit-synchronous DS1 signals

are mapped into seven VT groups or TUG-2s.

■28 asynchronous, byte-, or bit-synchronous J1 signals

are mapped into seven VT groups or TUG-2s.

■21 asynchronous, byte-, or bit-synchronous E1 signals

are mapped into seven VT groups or TUG-2s.

■Maps DS1 into VT1.5/TU-11/TU-12, J1 into VT1.5/TU-11/

TU-12, and E1 into VT2/TU-12.

ADM applications are supported via tributary loopback,

tributary pointer processing, and a low-order path overhead

access channel.

The VT/TU mapper supports automatic generation or

microprocessor overwrite of 1-bit RDI-V, enhanced RDI-V,

1-bit RFI-V, automatic downstream AIS generation, and five

J2 trace identifier modes.

The VT/TU mapper complies with GR-253-CORE, G.707,

T1.105, G.704, G.783, JT-G707, GR-499, and ETS 300

417-1-1.

5.7.1 Receive Direction

In the receive direction, the VT mapper terminates the data

stream it receives from the SPE mapper. It demultiplexes

the AU-3/TUG-3 into the VTs/TUs and checks the H4

multiframe alignment. A pointer interpreter for up to

28 VTs/TUs detects LOP, AIS, NDF, NORM, INC, and DEC

on each channe l.

The low-order path termination includes V5 byte

termination, J2 path trace, Z6/N2 tandem connection,

Z7/K4 enhanced RDI-V and low-order APS monitoring, and

the payload termination for asynchronous, byte- or bit-

synchronous signals. The V5 byte termination performs

BIP-2 check (bit or block mode), REI-V count, RFI-V, and

RDI-V detection, signal label monitoring, and automatic

AIS-V insertion (which can be inhibited).

The J2 monitor supports the following modes:

■Cyclic check

■SONET framing mode

■SDH framing mode

■Single byte check

In byte-synchronous mode, the receive demapper

generates a frame synchronization signal to indicate the

DS1 frame bit or the MSB of the E1 time slot 0. Additionally,

it provides the framer access to the received signaling bits.

Output of the VT mapper is a DS1/J1/E1 signal with a

gapped clock. It can be overwritten with AIS automatically

or upon microprocessor request.

5.7.2 Transmit Direction

In the transmit direction, the VT mapper gets a clock, data,

and frame synchronization signal from the multirate cross

connect. The input is retimed and is checked for a digital

loss of clock (LOC), an AIS condition, and low zeros

density. In byte-synchronous mode, the input signal is

additionally checked for loss-of-frame (LOF).

DS1/J1/E1 signals to the local STS-1 clock. In

asynchronous and bit-synchronous mode, it works as a bit-

oriented (64-bit) FIFO, and in byte-synchronous mode, as a

byte- wide (8-byte) buffer using a V5 byte marker bit (8-bit).

Overflow or underflow conditions are monitored and

reported.

In asynchronous and bit-synchronous mode, a fixed VT

pointer of 78 (VT1.5/TU-11) or 105 (VT2/TU-12) is

generated and the payload is mapped into the container

using a positive/null/negative bit stuffing mechanism

(C-bits and S-bits). In bit-synchronous mode, the bit stuffing

mechanism is disabled. In byte-synchronous mode, a

dynamic VT pointer value is generated using the V5

marker, implementing NORM, NDF, INC, and DEC

pointers.

The VT POH generation comprises V5 byte with BIP-2

generation, AIS-V, UNEQ-V insertion, automatic REI-V,

RFI-V, RDI-V, and enhanced RDI-V generation (Telcordia,

ITU-T), J2 path trace insertion via the microprocessor, Z6/

N2 byte insertion, and Z7/K4 byte insertion via the

microprocessor or low-order path overhead (LOPOH)

access channel.

The data stream is synchronized to the received internal

2 kHz synchronization pulse and is multiplexed to form the

STS-1/AU-3 signal, which is then output to the SPE

mapper.

When operating in byte-synchronous mode, the phase and

signaling bits from the framer are stored and inserted into

the mapped frame.

5.8 M13/E13 Multiplexer (M13/E13 MUX) Blocks

The M13/E13 block (12 blocks per device) is a highly

configurable multiplexer/demultiplexer for which each block

can be configured for M13 or E13 operation. The features

are as described below.

5.8.1 M13 MUX

The M13 may operate in the C-bit parity or M23 mode. In

the C-bit parity mode, the M13 provides a far-end alarm

and control (FEAC) code generator and receiver, an HDLC

transmitter and receiver, and an automatic far-end block

error (FEBE) generator.

28 DS1 inputs (in groups of four) or 21 E1 input signals (in

groups of three) can feed into individual M13 MUXs.

The M13 supports numerous automatic monitoring

functions. It can provide an interrupt to the control system,

or it can operate in a polled mode.

The M13 complies with T1.102, T1.107, T1.231, T1.403,

T1.404, GR-499, G.747, and G.775.

5.8.1.1 Receive Direction

The receive DS3 is monitored for loss of clock and loss of

signal (LOS) according to T1.231. The B3ZS decoder

accepts either the unipolar clock and data, or unipolar clock

and positive and negative data. It also checks for bipolar

coding violations. The transmit DS3 can be looped back

into the receive side after B3ZS decoding. The M23

demultiplexer checks for valid DS3 framing by finding the

frame alignment pattern (F-bits) and then locating the

multiframe alignment signal (M-bits). During each M frame,

the data stream is checked for the presence of the AIS

(1010) or idle (1100) pattern.

Within the M13 demultiplexer, there are four performance

monitoring counters for F- or M-bit, P-bit, E-bit parity, and

FEB E e r ro rs.

5.8.1.2 Transmit Direction

The incoming DS1/E1 clocks are first checked for activity or

loss-of-clock (LOC). The data signals are retimed and

checked for AIS and activity. DS1/E1 loopback selectors

allow the individual DS1/E1 signals within the received DS3

to be looped back toward the DS3 input. This loopback can

be performed automatically, or the user can force a DS1 or

E1 loopback.

The four DS1 or three E1 signals for each M12 MUX are

fed into single-bit, 16-word-deep FIFOs to synchronize the

signals to the DS2 frame generation clock. The fill level of

each FIFO determines the need for bit stuffing its DS1/E1

input. The M13 can handle DS1/E1 signals with nominal

frequency offsets of ±130 ppm and up to five unit intervals

peak jitter. The DS3 transmit clock is used to derive the

clock source for DS2 frame generation.

The transmit DS3 output can either be in the form of

unipolar clock and data, or unipolar clock and positive and

negative data. The DS3 data is B3ZS-encoded and can be

looped back from the receive DS3 input.

5 Block Description (continued)

5.8.2 E13 MUX

The E13 is a functional block that performs MUX/deMUX

from/to 16 E1s and one E3 signal compliant with ITU G.742

and ITU G.751. The E13 functional block is a highly

configurable multiplexer/demultip lexer. Each internal E12

MUX/deMUX and E23 MUX/deMUX is independently

configurable. The E3 inputs to the receive path can be

HDB3-encoded dual-rail (bipolar) signals or already

decoded single-rail signals with or without a BPV indication

input. The E1 inputs are expected to be decoded prior to

the E13 functional block. E3 transmit direction output can

be configured as HDB3-encoded dual rail (bipolar) or as

single rail. The E13 provides status and two-level priority

maskable interrupt outputs to the microprocessor.

E1 transmit path monitors detect loss of clock (LOC) and

AIS. The E3 receive monitor detects loss of signal (LOS),

loss of clock (LOC), bipolar violations (BPV), AIS, and RAI.

E3 and E2 loopback modes are also available.

5.9 Multirate Cross Connect (MRXC) Block

The multirate cross connect (MRXC) functional block (four

per device) is a crosspoint switch for DS1/J1/E1, DS3/E3,

and path overhead I/O. The multirate cross connect routes

signals to/from the major functional blocks and external I/O

pins as necessary for each application. The MRXC can

multicast, route test patterns, idles, or alarm conditions to

any channel, and provide system loopbacks.

The multirate cross connect can interconnect up to 84

individual DS1/E1 channels between the framer, M13/E13

multiplexer, VT mapper, or jitter attenuator.

Independent signal paths for remote alarm indication (RAI),

alarm indication signal (AIS), and byte-synchronous frame

synchronizing signals on channels between the VT mapper

or M13/E13 and the framer are supported. Receive pointer

adjustment information is routed to the jitter attenuator

functional block for each channel originating in the VT

mapper.

For DS3/E3 signals, the multirate cross connect supports

configuration of interconnects between the following:

■The M13/E13 and the SPEMPR

■External I/O interconnection to the M13/E13 or SPEMPR

■Insertion/monitoring of unframed test patterns from the

test-pattern generator/monitor functional block

The test-pattern generator/monitor functional block (TPG/

TPM) provides test signals and monitors inputs for signals

to/from the multirate cross connect. The TPG can generate

a set of test signals at DS1, E1, and DS3, E3, or

STS-1 rates. There is only one test pattern generator and

monitor per signal rate.

For overhead, the MRXC provides an access channel

connection (TOAC and POAC) to the SPEMPR or to the

TMUX functional blocks.

The MRXC also provides the interface to the external pins.

The external pins may be configured to work in two modes:

a transport mode and a network serial multiplexed interface

(NSMI) mode. The first mode is used to provide dedicated

access to the device for DS3/E3 signals, and the NSMI

mode is described below.

■Network serial multiplexed bus (NSMI):

—6- or 8-pin serial interface.

—Transmit and receive clock and data at 51.84 MHz (or

44.736/34.368 MHz for M13/E13).

—Accommodates one STS-1 SPE.

—Provides a minimal pin count interface for data and

inverse multiplexing for ATM (IMA) applications

without slip buffers.

—Two modes of operation:

! M13/E13—proprietary transport format with DS3/

E3 framing.

! SPE—proprietary transport format mapped into an

STS-1/AU-3.

5 Block Description (continued)

5.10 DS1 Digital Jitter Attenuator (DS1/E1 DJA)

Block

The DS1/E1 digital jitter attenuator (DS1/E1 DJA) block (12

per device), contains 28 copies of the digital jitter

attenuator for a total of 336/252 DS1/E1 DJAs. These

digital jitter attenuator functional blocks can operate in two

different modes: as a DS1 or as an E1 jitter attenuator.

In both modes, the digital jitter attenuator can be

provisioned to always operate as a second-order PLL, or it

can switch to act as a first-order PLL during VT pointer

adjustments to help meet MTIE requirements. The period

of time in the first-order mode is provisionable. The PLL

bandwidth is provisionable between 0.1 Hz and 0.5 Hz, and

the damping factor for these bandwidths varies between 2

and 0.5 to accommodate a number of different system

constraints.

The DS1/E1 DJA allows automatic pass-through of an AIS

from both the VTMPR and M13/E13 blocks.

5.11 DS3 Digital Jitter Attenuator (DS3/E3 DJA)

Block

The HypermapperLite device contains four DS3/E3 digital

jitter attenuator blocks containing six DS3/E3 digital jitter

attenuators each. These digital jitter attenuators can

operate in two different modes: as a DS3 or as an E3 jitter

attenuator. The PLL bandwidth and the sampling ratio can

be set over a wide range to accommodate a number of

different system co nstraints.

The DJA functional block accepts/delivers DS3/E3 clock

and data from/to the multirate cross connect functional

block. The PLL bandwidth, damping factor, and sampling

rates are programmable. Output is programmable as data

only, as B3ZS-coded, or as HDB3-coded.

5.12 Test Pattern Generator/Monitor (TPG/TPM)

Block

The test pattern generator/test pattern monitor functional

block (TPG/TPM) consists of a set of configurable test

pattern generators and monitors for local self-test,

maintenance, and troubleshooting operations.

The TPG feeds one or more DS1/E1 test signals (via data,

clock, and FS or AIS signal paths) to the multirate cross

connect, which can redistribute or broadcast these signals

to any valid channel in the framer, M13/E13 MUX, or VT

mapper functional blocks. The TPG can also generate

DS3, E3, or STS-1 test signals.

Any channel arriving at the multirate cross connect can be

routed to the test monitor. The test monitor can

automatically detect/count bit errors in a pseudorandom

test sequence, loss of frame (DS1/E1 only), or loss of

synchronization situation. The TPM can provide an

interrupt to the control system, or it can be operated in a

polled mode.

Simultaneous testing of DS1, E1, and DS3, E3, or STS-1

signals is supported with one channel for each (one

channel shared between DS3, E3, and STS-1).

Supported test patterns are a quasirandom signal (QRSS),

a pseudorandom bit sequence (PRBS23, PRBS20,

PRBS15), alternating zeros/ones, an all-ones pattern, and

a 16-bit user-provisionable pattern.

The DS1 and E1 test patterns can be transmitted as either

unframed or as the payload of a framed signal, as defined

in ITU-T Recommendation O.150. DS3, E3, or STS-1

patterns are unframed only.

Under register control, single bit-errors can be injected into

any test pattern.

5.13 Low-Orde r Pa th Over Head

This block is shown in Figure 1, but it cannot be addressed

by the MPU. It is shown as a virtual block to highlight that

the LOPOH bytes from the TMUX, SPEMPR, and VTMPR

can be provisioned to appear at the LOPOH device pins.

Provisioning is accomplished by setting registers in the

device via the MPU.

alarms:

■Loss of receive clock

■Loss-of-frame

■Alarm indication signal (AIS)

■Remote frame alarms

■Remote multiframe alarms

These alarms are detected as defined by the appropriate

ANSI, AT&T, ITU, and ETSI standards.

ITU, is provided through counters monitoring the following:

■Frame bit errors

■CRC errors

■Errored eve n ts

■Errored seconds

■Bursty errored seconds

■Severely errored seconds

In-band loopback activation and deactivation codes can be

transmitted to the line via the payload or the facility data

link. In-band loopback activation and deactivation codes in

the payload or the facility data link are detected.

5.14.3 Signaling Processor

The signaling processor supports the following modes:

■Superframe (D4, SLC-96): 2-state, 4-state, and 16-state

■VT 1.5 SPE: 2-state, 4-state, and 16-state

■Extended superframe: 2-state, 4-state, and 16-state

■CEPT: common channel signaling (CCS) (TS-16)

■J-ESF handling groups

Signaling features supported per channel are as follows:

■Signaling debounce

■Signaling freeze

■Signaling interrupt upon change of state

■Signaling inhibit

■Signaling stomp

Voice and data channels are programmable in the DS1

robbed-bit signaling modes. The entire payload can be

forced into a data-only (no signaling channels) mode

(i.e., transparent mode, achieved by programming one

control bit).

Signaling access occurs through the on-chip signaling

registers.

5.14.4 Facility Data Link (FDL) Processor

The receive facility data link processor monitors the bit-

oriented ESF data-link messages defined in ANSI T1.403.

The transmit facility data link unit overrides the FDL-FIFO

for the transmission of the bit-oriented ESF data-link

messages defined in ANSI T1.403-1995.

The FDL processor extracts and stores data link bits from

three different frame types as follows:

■D-bits and delineator bits from the SLC-96 multi-

superframe.

■Data link bits from DDS frames (bit 6 of time slot 24).

■Two multiframes of Sa[4:8] bits from timeslot 0 in CEPT

basic and CRC-4 multiframes.

The respective bits are always extracted from frame-

aligned frames and are stored in a stack. The processor

controls notification of stack updates through the interrupt

(maskable) registers.

The transmit FDL functional block performs the

transmission of D-bits into SLC-96 Superframes, Sa-bits in

CEPT frames, and D-bits in DDS frames.

■In SLC-96 frames, the D and delineator bits are always

sourced from this functional block when the block is

enabled for insertion.

■In DDS frames, the data link bits are always sourced

from this functional block when this block is enabled for

insertion. This functional block also provides the

capability to transmit BOMs (bit-oriented messages) in

the data link channel of ESF links.

■In CEPT frames, the Sa bits are sourced from the Sa

stack within this functional block. The data link functional

block only responds with valid data when selected by the

Sa source control bits.

5.14.5 HDLC Unit

The HDLC processor formats th e HDLC packets for

insertion into the programmable channels. A channel can

be any number of bits (1 to 8) from a time slot.

The maximum number of channels is 64. The maximum

channel bit rate is 64 kbits/s. The minimum channel bit rate

is 4 kbits/s. Each channel is allocated 128 bytes of storage.

HDLC processing of data on the facility data link (PRMs,

Sa-bits, or otherwise) is implemented by assigning the FDL

bit position to a logical HDLC channel.
