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:
51.84 Mb/s | 28 DS1s or 1 DS3 | |
155.52 Mb/s | 3 | |
155.52 Mb/s | Concatenated, indivisible payload | |

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.
