Layer
A level in the hierarchy of telecommunications protocols. Protocols in the higher
layers inter-operate with those in the lower layers.
LOCS
Loss Of Cell Synchronization
LOSS
Loss Of Scrambler Synchronization
M23 Parity
A DS3 framing format. See also C-Bit Parity.
MAC address
A 12-digit (48 bit) hexadecimal number that identifies a specific network station
and allows messages to be directed to that station only. Because the IEEE has
assigned identifiers for each hardware manufacturer, no two pieces of equipment
have the same address. The address assigned according to the IEEE plan is
referred to as a device’s globally-administered station address. Some devices
provide an option for the user to assign a different station address that will
override the original. This type of address is referred to as a locally-administered
station address. The station address is also commonly called a MAC address,
Ethernet address, Token-Ring address, or physical address.
Manager
A node that collects network management information from agents.
Management station
A station that collects network management information from probes.
MAU (Medium Attachment Unit)
The assembly used to provide the physical connection and access to a LAN. It is
the device on the LAN that detects collisions. (A transceiver is also called a MAU
in the IEEE 802.3 standard.)
Mbps
Megabits per second.
