multimedia traffic classes (MMTC)
Subscriber options that enable you to select the traffic handling preferences
from the network to meet the application requirements. MMTC handle delay-
sensitive multimedia traffic and minimize the delay transfer time and delay
variance through the Nortel Multiservice Switch network.
multimode (MM)
Optical fiber that is capable of propagating light signals of two or more
wavelengths (modes).
multiple priority system (MPS)
Nortel Multiservice Switch system proprietary priority system which defines
traffic importance in terms of three emission priorities and four discard
priorities.
multiport aggregate device
A multiport aggregate device breaks out the ports of the 32-port E1 AAL
function processor (FP). Each multiport aggregate device provides
connections for 16 E1 ports. You must use two multiport aggregate devices to
break out all the ports of the FP.
multiprotocol label switching (MPLS)
MPLS is a label-swapping, networking technology that forwards packet traffic
over multiple, underlying layer-2 media. This technology integrates layer-2
switching and layer-3 routing by linking the layer-2 infrastructure with layer-3
routing characteristics. Layer-3 routing occurs at the edge of the network, and
layer-2 switching takes over in the MPLS network core.
multipurpose voice platform enhanced echo cancellation (MVP-E)
An MVP function processor with an on-board daughter card that provides
echo cancellation capabilities according to ITU-T G.164, G.165 and G.168.
The five types of Nortel Multiservice Switch MVP-E function processor are 1-
port DS1 MVP-E, 1-port E1 MVP-E, 4-port DS1 MVP-E, 4-port E1 MVP-E and
1-port TTC2M MVP-E.
multi-rate (MR)
The capability of a function processor (FP) to operate at multiple line rates
according to specific configurations. The 4-port multi-rate POS and ATM FP
(4pMRPosAtm) is an example of a multi-rate FP.
multiservice access function processor (MSA32 FP)
A function processor possessing 32 DS1 or E1 ports. The MSA FP is capable
of running multiple services on Nortel Multiservice Switch nodes.
