Building a Millennium

The Millennium system is available in two cabinet configurations: the 8-slot cabinet, which can be extended incrementally with 4-slot expansion modules, and the 16-slot cabinet, which makes up one shelf. The Millennium can grow up to 4 shelves for a total of 1,024 ports.

The Millennium is built upon two types of cards: control and interface cards. The control cards consist of the System Controller and the Common Services Card in single cabinet configurations, and the Concentrator Cards or Fiber Interface Cards in multi-shelf or remote shelf configurations.

Interface Cards
Universal porting allows trunk and station cards to be assigned in any vacant card slot. The size and quantity of cabinets installed on each shelf determines the number of card slots available, up to a maximum of 16 cards per shelf.

Digital Line Cards

The Digital Line Card (DLC) provides eight s-loops, each with two 64 Kbps B-channels, and one 16 Kbps D-channel. You can configure each talk path for a single digital telephone (16 stations per card) or use two talk paths to give a single digital telephone added capability such as Off-Hook Call Announce and circuit switched data.

Analog Line Card

The Analog Line Card (ALC) supports up to 16 tip and ring circuits. A baby board mounted on each circuit determines whether the circuit supports a loop-start trunk, ground-start trunk, Tie line, DID trunk, single line telephone, off-premise station, modem, voice mail port, recorder, night ringer or customer-supplied external security alarm equipment. In addition, each trunk circuit has the option of receiving Incoming Calling Line Identification (ICLID) via the ICLID baby board.

The T-1/ISDN PRI Card provides a 1.544 Mbps interface with a 24-channel T1 trunk span or an ISDN-compatible primary rate interface signaling trunk span. It provides digitized voice and data transmission between the Millennium and distant office interfaces.

The E-1/ISDN PRI Card provides the European standard 2.048 Mbps digital interface. R1, R2, Australian and Russian implementation of E1 are also supported. All protocols and features supported by the T-1/ISDN PRI Card are available on the E-1 card. The card also operates to provide digitized voice transmission between two networked Millennium systems.

Fiber Interface and Remote Fiber Interface Cards

A Millennium system configured with fiber optic cable interconnection to remote shelves provides an economical alternative to a T-1. It is transparent, nonblocking, and permits shelves in the system to be located up to 2 km (1.24 miles) from the main shelf. The Remote Fiber Interface Assembly is a two-card set that includes a Fiber Interface Assembly and a Remote Fiber Interface Assembly. A duplex (two fiber) multimode cable is used to connect each of the remote shelves with the system shelf. A remote fiber system has a main shelf and a maximum of three remote shelves.

3100 Line Card
The 3100 Line Card makes the transition from the ITT System 3100 to the Millennium easy and cost efficient for the end user. The 3100 Line Card allows System 3100 telephones and DSS/BLF units to be installed behind the Millennium, thereby minimizing retraining and protecting prior investments.

Designed with ISDN as its cornerstone, the Millennium fulfills all your communications needs of today and addresses those applications of tomorrow. This flexibility and foresight ensure eOn’s place as an industry leader well into the next century.
