Specifications

Pseudowire
Point-to-point connections set up to emulate (typically Layer 2)
native services like ATM, Frame Relay, Ethernet, TDM, or
SONET/SDH over an underlying common packet-switched network
(Ethernet, MPLS or IP) core. Pseudowires are defined by the IETF
PWE3 (pseudowire emulation edge-to-edge) working group.
SAToP
Structure-Agnostic Time Division Multiplexing (TDM) over Packet. A
method for encapsulating Time Division Multiplexing (TDM) bit-
streams (T1, E1, T3, E3) that disregards any structure that may be
imposed on these streams, in particular the structure imposed by
the standard TDM framing.
Space
In telecommunications, the absence of a signal. Equivalent to a
binary 0.
T1
A digital transmission link with a capacity of 1.544 Mbps used in
North America. Typically channelized into 24 DS0s, each capable of
carrying a single voice conversation or data stream. Uses two pairs
of twisted pair wires.
Throughput
The amount of information transferred through the network
between two users in a given period, usually measured in the
number of packets per second (pps).
TDMoIP®
TDM over IP is a standards-based pseudowire transport technology
that extends voice, video or data circuits across packet-switched
networks simply, transparently and economically. TDMoIP supports
the multiple signaling standards, OAM mechanisms and clock
recovery features demanded by TDM networks for carrying
voice-grade telephony.
