http://www.cisco.com/c/en/us/td/docs/routers/crs/software/crs_r4-2/interfaces/configuration/guide/hc42crsbook/hc42t3e3.htmlT3 is a type of digital communication line that can transmit data at a rate of 44.736 Mbps. It is commonly used in high-bandwidth applications, such as internet service provider backbones, and for carrying voice and data traffic between large campuses or metropolitan areas.
When configuring T3 interfaces, it is important to select the appropriate framing type to ensure that the data is transmitted correctly. The framing type defines how the data is structured and synchronized for transmission over the T3 line.
Here are the two correct framing types when configuring T3 interfaces:
M23: M23 is a T3 framing type that uses 24 frames per second, with each frame consisting of 193 bits. This framing type is commonly used in Europe and Japan.
C-bit parity: C-bit parity is a T3 framing type that uses 12 frames per second, with each frame consisting of 672 bits. This framing type is commonly used in North America.
The other options listed in the question are not correct framing types for T3 interfaces:
- 832: This is a T1 framing type that is not applicable to T3 interfaces.
- Extended Super Frame: This is a T1 framing type that is not applicable to T3 interfaces.
- 751: This is a T1 framing type that is not applicable to T3 interfaces.
- Super Frame: This is a T1 framing type that is not applicable to T3 interfaces.
In summary, when configuring T3 interfaces, it is important to select the appropriate framing type, such as M23 or C-bit parity, to ensure that the data is transmitted correctly.
