STP
Signaling Transfer Point: A high speed, reliable, special purpose packet switch for
signaling messages in the SS7 network.
STP
Shielded Twisted Pair: A cable containing one or more twisted pair wires with each
pair having a shield of foil wrap.
STS
Start Synchronous
STS-1
Synchronous Transport Signal 1: SONET standard for transmission over OC-1
optical fiber at 51.84 Mbps.
STS-n
Synchronous Transport Signal “n:” (where n is an integer) SONET standards for
transmission over OC-n optical fiber by multiplexing "n" STS-1 frames, (e.g., STS-
3 at 155.52 Mbps STS-12 at 622.08 Mbps and STS-48 at 2.488 Gbps).
STS-nc
Synchronous Transport Signal "n" concatenated: (where n is an integer) SONET
standards for transmission over OC-n optical fiber by multiplexing "n" STS-1
frames, (e.g., STS-3 at 155.52 Mbps STS-12 at 622.08 Mbps and STS-48 at 2.488
Gbps but treating the information fields as a single concatenated payload).
Sublayer
A logical sub-division of a layer.
Subnet
The use of the term subnet to mean a LAN technology is a historical use and is not
specific enough in the MPOA work. Refer to Internetwork Address Sub-Group,
Direct Set, Host Apparent Address Sub-Group and One Hop Set for more specific
definitions.
Subnetwork
A collection of managed entities grouped together from a connectivity perspective,
according to their ability to transport ATM cells.
