TMPR28051 STS-1/AU-3 (STM-0) Mapper

Features

Maps signals in one of the following ways:

— Maps up to 28 asynchronous DS1 signals to

SONET STS-1 via VT Groups, or SDH AU-3 via

TUG-2.

— Maps up to 21 asynchronous E1 signals to SDH

AU-3 via TUG-2, or SONET STS-1 via VT

Groups.

— Maps any valid combination of DS1/E1 signals

at the VT Group/TUG-2 level.

PLL-free receive operation using built-in digital jit-

ter attenuators.

High-speed microprocessor interface configurable

to operate with most commercial microprocessors.

Inserts valid B1, B2, and B3 bit interleaved parity

(BIP) in the transmit direction.

Detects and counts B1, B2, and B3 BIP-8 errors on

either a bit or block basis for performance monitor-

ing in the receive direction.

Detects and counts V5 BIP-2 errors on either a bit

or block basis for performance monitoring.

Configurable continuous B1, B2, B3, and V5 BIP-2

error insertion.

Configurable remote error indication (REI) inser-

tion for B2, B3, and V5 BIP-2 errors.

Detects and counts remote errors.

Built-in test pattern insertion and drop for setup

and maintenance.

Configurable VT1.5/TU-11 slot selection for DS1

insertion and drop.

Configurable VT2/TU-12 slot selection for E1

insertion and drop.

Detects STS-1 path loss of pointer (LOP-P), loss of

H4 multiframe (H4LOMF), path alarm indication

signal (AIS-P), and path remote defect indication

(RDI-P).

Automatic receive monitor functions include VT/TU

remote defect indication (RDI-V), VT/TU remote

error indication (REI-V), BIP-2 errors, VT/TU AIS

(AIS-V), and VT/TU loss of pointer (LOP-V).

Automatic receive monitoring functions can be

configured to provide an interrupt to the control

system, or the device can be operated in a polled

mode.

User configurable for VT/TU label, AIS-V, RDI-V,

REI-V, force BIP-2 errors, or unequipped tributary

insertion.

Typical 3.3 V operation with 5 V TTL tolerant I/O

and boundary scan.

–40 °C to +85 °C temperature range.

208-pin shrink quad flat pack (SQFP) package.

Provides alarm and control features to easily

implement the latest release of the following stan-

dards:

GR253-CORE (12/97 with the exception of

GR-253 section 6.2.1.1.8.C), G.707 (3/96),

G.783 (1/94), G.823.393, T1.105-1995,

T1.105.02-1995, T1.105.03-1994,

T1.105.03A-1995, T1.105.07-1996,

T1.105.09-1996, ETS300.147 (1/95),

ETS300.417-1-1 (1/96).

Applications

SONET/SDH path termination multiplexers

SONET/SDH add/drop multiplexers

SONET/SDH cross connects

Digital access cross connects

DS1/E1 broadcast

SONET/SDH test equipment

Description

The Lucent Technologies Microelectronics Group

TMPR28051 device is designed to map any valid

combination of DS1 and E1 signals into a stream at a

rate of 51.84 Mbits/s. This device provides all of the

functions necessary to insert and drop any valid com-

bination up to 28 asynchronous DS1 signals or 21

asynchronous E1 signals into an SPE.
