DS1C
3.152 Mb/s
2 DS1s
DS2
6.312 Mb/s
4 DS1s
DS3
44.736 Mb/s
28 DS1s
Synchronous data rates (SONET) are defined as:
STS-1/OC-1
51.84 Mb/s
28 DS1s or 1 DS3
STS-3/OC-3
155.52 Mb/s
3 STS-1s byte interleaved
STS-3c/OC-3c
155.52 Mb/s
Concatenated, indivisible payload
STS-12/OC-12
622.08 Mb/s
12 STS-1s, 4 STS-3cs, or any mixture
STS-12c/OC-12c
622.08 Mb/s
Concatenated, indivisible payload

Protocol - used by gateways in an internet, connect-
ing autonomous networks.
EISA (Extended Industry Standard Architecture)
- a bus architecture for
desktop computers that provides a 32-bit data passage while maintaining

- a FORE program that shows and manipulates MAC and ATM address
mappings for LAN Emulation Clients (LECs).
elconfig
- a FORE program that shows and modifies LEC configuration.
Allows the user to set the NSAP address of the LAN Emulation Configuration
Server (LECS), display the list of Emulated LANs (ELANs) configured in the
LECS for this host, display the list of ELANs locally configured along with the
membership state of each, and locally administer ELAN membership.
