DHCP IP is a network protocol that automatically assigns IP addresses to devices on a network.

• DHCP stands for Dynamic Host Configuration Protocol

• It allows devices to obtain IP addresses and other network configuration information dynamically

• DHCP servers assign IP addresses to devices within a network

• DHCP lease time determines how long an IP address is valid for a device

CSFB (Circuit Switched FallBack) allows a 4G LTE device to fallback to a 2G network for voice calls.

• CSFB is used when a 4G LTE device needs to make a voice call, as LTE is a data-only network.

• The device switches to a 2G network temporarily for the voice call and then switches back to LTE for data.

• CSFB helps ensure seamless voice call connectivity for LTE devices.

• Example: When a user on a 4G network makes a voice call, ...read more
