Network Element Management
Fast, efficient and flexible management is the key to success for any network.
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.

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.

Two types of conferences are possible:
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
