t1 demark has t1/hdsl  (screw terminals) yel/blk/red/green
 and data dds (screw terminals) yel/blk/red/green
all listed as circuit 1.   I know it only takes two pair to extend
the t1, but which screw terminals do I use ?

how do I extend t1 from outside demark

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
