discussed with another group of students, with the entire class, or with the instructor.

Scenario

Your medium-sized company is upgrading its network. To make the most of the equipment currently in use, you

locations. Each branch has its own ISP requirements to consider.

To update the devices, focus on the following WAN modules access types:

• Ethernet

• Broadband

• T1/E1 and ISDN PRI

• BRI

• Serial

• T1 and E1 Trunk Voice and WAN

• Wireless LANs and WANs
