Use search engines and websites to research the following WAN technologies to complete the table below:

Last Mile Media
WAN Technology Dedicated Copper Fiber Wireless Speed/Range
Connection (yes/no) (yes/no) (yes/no) (yes/no)

T1/DS1 yes yes yes yes 1.544 Mb/s
T3/DS3 yes yes yes yes 44.736Mb/s OC3(SONET) yes no yes no 155.52 Mb/s
Frame Relay yes yes xxx yes 56Kb/s-1.544 Mb/s
ATM yes yes yes yes 155 Mb/s-622 Mb/s
MPLS yes yes yes yes Up to 10 Gb/s
EPL(Ethernet-
Private Line) yes yes yes no Up to 10 Gb/s

Explanation:

I am attaching the table as an image with updated table containing required information for the following WAN technologies.

T1/DS1 => Digital Signal 1 (T-Carrier 1),

T3/DS3 => Digital Signal 3 (T-Carrier 3),

OC3 (SONET) => Optical Carrier 3 (Synchronous Optical Networking),

Frame Relay,

ATM => Asynchronous Transfer Mode,

MPLS => Multi-protocol Label Switching,

EPL => Ethernet Private Line.

Although you have mentioned most of the information yourself, there were some wrong data in it.  So I have updated them with correct information in the attached table.

i do not get the question.
