The Alcatel-Lucent 1511 BA is a 2 Mb/s 30-channel multiservice access multiplexer, which can be used across
a wide range of companies for business access and utility network applications. It also provides grooming functionalities for GSM and wireless local loop networks. For example, railway networks, pipelines for oil, gas and
water and power utilities use utility network applications with different sets of service requirements. Whereas
railway and pipeline installations require a linear or ring type of network with drop-and-insert functions, other
installations require a mesh type of network. For all of these applications the Alcatel-Lucent 1511 BA offers
the ideal solution.

Network Element Management
Fast, efficient and flexible management
is the key to success for any network.
Alcatel-Lucent’s network management
software, based on ITU-T M.3010,
satisfies all three of these criteria in an
easy-to-learn and easy-to-use package.
Network management of all elements
in a system is performed from a single
terminal comprising a compatible PC
running Windows or a workstation
loaded with Alcatel-Lucent network
management software.

Architecture
The PCM Controller (PCMC2) interfaces
the users and the E1 aggregate side.
The controller connects the analog,
data or N x 64 kb/s data terminal
channels of the tributary boards,
or the PCMC2 in slave mode, to the
2,048 kb/s G.703/G.704 aggregate
via an internal serial bus.
The PCMC2 provides:
•	 A transmission/switching interface
and HDB3 to binary coding/decoding, retiming, frame alignment and
supervision, cyclic redundancy check
#4 (CRC4) generation/monitoring,
channel mapping, CAS, alarm treatment and test facilities
•	 An asynchronous serial communication channel to a central alarm
supervising unit through which the
user can communicate about equipment configuration, status and alarms
•	 Two serial channels for embedded
operation channel (EOC). These
channels can be used for transport
of network management protocols
between the network element and
its centralized management units.
Power unit boards for DC/DC and AC/
DC conversion are provided for each
subrack assembly and can be duplicated for redundancy.

Applications
POTS Subscriber Multiplexer
The POTS subscriber multiplexer is used
in the subscriber network and allows a
flexible mix of voice and data interfaces. Adaptation of the signaling to
the customer’s requirements can be
done easily.

ISDN-BRI
The Alcatel-Lucent 1511 BA can be
used for ISDN-BRI applications. Both
2- and 4-wire (U with line code 2B1Q
and S0/I.430) interfaces are available.
Each interface uses three timeslots
(2B + D16/M) on the 2 Mb/s G.703 link.

Hot Line

High Quality Audio Tributaries

Hot Line is a bi-directional application,
with a centralized battery set, where
one subscriber hooks off and the other
is called without dialing. It uses the
same board as the POTS application.
This board’s lines can be programmed
either as a POTS or Hot Line.

The Alcatel-Lucent 1511 BA can perform unidirectional audio transmission.
This audio board uses MPEG-2 15 kHz
sampling.

Ringdown
Manual Ringdown (MRD) is an AlcatelLucent 1511 BA application that permits
the connection of two local battery
(LB) telephone sets or the connection
of a local battery telephone set to a
central switch board. This application
is widely used by stock market brokers.
It requires the use of a special ringdown board.

Direct Dialing In
The Alcatel-Lucent 1511 BA provides
direct dialing in (DDI), a feature whereby
the dialing information is sent directly
from the PSTN to the PABX, which
then sets up the connection to the
PABX subscriber.

Data Multiplexer
The Alcatel-Lucent 1511 BA can be used
as a data multiplexer. The possible data
tributaries are:

2/4-Wire Audio Interface
Connection between analog modems
or PABX ports for tie-line connections
can be achieved with the 2/4-wire
audio board. Variants with or without
E&M wires are available.

Conference Bridge
Two types of conferences are possible:
•	 Master-slave conference: One participant is considered the “master” and
all others are considered “slaves.”
One master with up to 29 slaves is
possible.
•	 Full conference: This type of conference is used when all participants
need to share information equally.
Every participant receives information from all other participants but
himself or herself.
These two types of conferences can be
used for voice, data or signaling.

•	 64 kb/s G.703 contra-directional

The conference bridge is a simple and
useful board in networks with super­
visory control and data acquisition
(SCADA) and/or audio dispatching
requirements.

•	 2 Mb/s and N x 64 kb/s G.703/G.704.
(fractional E1)

Dry Relay Contacts

•	 64 kb/s G.703 co-directional — with
optional E&M signaling

•	 Low speed: 75 b/s to 64 kb/s for V.36,
V.35, V.28 and X.21
•	 N x 64 kb/s (N = 1 to 31); interfaces:
V.35, V.36 and X.21

Remote Data Unit
The Alcatel-Lucent 1511 BA provides an
integrated digital interface to remote
data units (RDUs). The RDUs are provided
with one or two of the following interfaces in any combination: V.35, V.36, X.21
and V.24/V.28 up to 128 kb/s, analog
and 64 kb/s G.703 co-directional interfaces. Performance monitoring on the
RDU is foreseen on the digital link.

Alcatel-Lucent 1511 BA | 2 Mb/s 30-Channel Primary Rate Multiplexer  |  Data Sheet

This board has a number of detectors
for dry relay contacts. It is used for
collecting alarm indications of collocated equipment and enables the
visualization of alarm states on the
same craft terminal or server as that
being used for the multiplexer
functions.

Integrated Optical Transport
Boards for optical PDH transport of
4 or 16 E1 streams can be plugged into
the Alcatel-Lucent 1511 BA subrack and
managed by the same management
tools. See the Alcatel-Lucent 1521 FL
and the Alcatel-Lucent 1531 FL.

Automatic Protection Switch

Technical Specifications

The automatic protection switch (APS)
enables route protection on E1 level.
If used, the Alcatel-Lucent 1511 BA
transmits data via two different E1
routes. At the receive side, data coming
from the preferred route is used; if this
route fails, data is taken from the
other side.

Main Characteristics

Ethernet Switching
On an E1 trail across multiple AlcatelLucent 1511 BA multiplexers, a group
of 64-kb timeslots (N: 1...31) is reserved
to carry Ethernet frames. In each AlcatelLucent 1511 BA, one 10/100Base-T LAN
board (LANtrib) can drop/insert its local
Ethernet traffic onto these reserved
timeslots. To connect multiple Ethernetbased end devices, the LANtrib offers
five external RJ-45 interfaces. The
LANtrib also switches LANs across multiple and distinct Alcatel-Lucent 1511
BA multiplexers. Switching between
the local five Ethernet ports runs at
wire speed.
