Alcatel-Lucent1511 BA

Business Access Multiplexer | 2 Mb/s 30-ChannelPrimary Rate Multiplexer

The Alcatel-Lucent1511 BA is a 2 Mb/s30-channelmultiservice 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 withdrop-and-insertfunctions, other installations require a mesh type of network. For all of these applications theAlcatel-Lucent1511 BA offers the ideal solution.

Network Element Management

Fast, efficient and flexible management is the key to success for any network. Alcatel-Lucent’snetwork management software, based onITU-TM.3010, satisfies all three of these criteria in aneasy-to-learnandeasy-to-usepackage. Network management of all elements in a system is performed from a single terminal comprising a compatible PC running Windows or a workstation loaded withAlcatel-Lucentnetwork management software.


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.


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.


The Alcatel-Lucent1511 BA can be used forISDN-BRIapplications. Both 2- and4-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

Hot Line is a bi-directionalapplication, 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.


Manual Ringdown (MRD) is an Alcatel-

Lucent 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-Lucent1511 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-Lucent1511 BA can be used as a data multiplexer. The possible data tributaries are:

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

64 kb/s G.703 contra-directional

2 Mb/s and N x 64 kb/s G.703/G.704.

(fractional E1)

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-Lucent1511 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.703co-directionalinterfaces. Performance monitoring on the

RDU is foreseen on the digital link.

High Quality Audio Tributaries

The Alcatel-Lucent1511 BA can perform unidirectional audio transmission.

This audio board uses MPEG-215 kHz sampling.

2/4-WireAudio Interface

Connection between analog modems or PABX ports for tie-lineconnections can be achieved with the2/4-wireaudio board. Variants with or without E&M wires are available.

Conference Bridge

Two types of conferences are possible:

Master-slaveconference: 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.

The conference bridge is a simple and useful board in networks with super­ visory control and data acquisition

(SCADA) and/or audio dispatching requirements.

Dry Relay Contacts

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-Lucent1511 BA subrack and managed by the same management tools. See theAlcatel-Lucent1521 FL and theAlcatel-Lucent1531 FL.

Automatic Protection Switch

The automatic protection switch (APS) enables route protection on E1 level. If used, the Alcatel-Lucent1511 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.

Ethernet Switching

On an E1 trail across multiple AlcatelLucent 1511 BA multiplexers, a group of 64-kbtimeslots (N: 1...31) is reserved to carry Ethernet frames. In each AlcatelLucent 1511 BA, one10/100Base-TLAN board (LANtrib) can drop/insert its local Ethernet traffic onto these reserved timeslots. To connect multiple Ethernetbased end devices, the LANtrib offers five externalRJ-45interfaces. The LANtrib also switches LANs across multiple and distinctAlcatel-Lucent1511 BA multiplexers. Switching between the local five Ethernet ports runs at wire speed.
