Setting the Interframe Time Fill Pattern

The router transmits an interframe time fill (IFTF) pattern when there is no data to

transmit on a channel. You can select the IFTF pattern for data transmission across

this logical line:

• Flags selects a 0x7E pattern (0 1 1 1 1 1 1 0).

• Idles selects a 0xFF pattern (1 1 1 1 1 1 1 1).

The router uses Flags by default.

See the Interframe Time Fill Character parameter on page A-39

for information.

Setting the CRC Size

By default, the router uses the 16-bit CRC type. The router appends a 16-bit CRC

to the transmitted frames and performs a 16-bit CRC on received frames. You can

change to 32-bit CRC, where the router appends a 32-bit CRC to transmitted

frames and performs a 32-bit CRC on received frames.

You can set CRC size for the logical line.

See the CRC Size parameter on page A-40

for information.

Setting the MTU Size

The router uses the transmit/receive buffer size (MTU) to configure the largest

frame that the router can transmit or receive across this MCE1 port. The router

discards frames larger than this value. The MTU is 1600 bytes by default. You can

change it to any size from 3 to 4608 bytes for the logical line.

See the MTU Size parameter on page A-40

for information.
