Glossary 263

This feature is different from Call Forward in two ways. Line redirection redirects only external calls, and redirects calls to destinations outside the system. Call forward redirects calls only to destinations within the system.

Link

If the Business Communications Manager system is connected to a Private Branch Exchange (PBX), the Link signal is used to access special features. The Link signal can be included as part of a longer stored sequence on an External Autodial button or in a Speed Dial code. The Link symbol uses two of the 24 spaces in a dialing sequence.

Local Area Network (LAN)

A network of interconnected computers, such as the Business Communications Manager, sharing the resources of a single processor or server within a relatively small geographic area.

mailbox

A storage place for voice messages on Business Communications Manager Voice Messaging.

Meridian 1 ISDN Primary Rate Interface

This is the MCDN protocol which is used between members of the Nortel Networks Meridian family of Private Telecommunication Network Exchanges. The signalling information is carried via time slot 16 of a 2.048 Mbit/s digital transmission system.

MHz

A unit of measure indicating frequency in millions of cycles per second.

microprocessor

The Central Processing Unit (CPU) component that controls all activity inside the Business Communications Manager.

mirrored disks

In terms of the Business Communications Manager, this refers to the BCM1000 configuration that consists of two hard disks and a RAID board. The RAID board ensures that both disks contain exact copies of each other. If one disk fails, the other disk assumes control. Thus, you can time the replacement of the disabled disk to suit your maintenance schedule. This system does not replace the need for current BRU copies.

modem

A communications device that allows computers to exchange data over telephone lines.

music source

You can connect a radio or other source of music to the system to provide music for the Music on Hold and Background Music features. A music source is not part of the Business Communications Manager system components.
