Parameter: Interframe Time Fill Character
Path: Configured MCE1 or MCT1 Connector > MCE1/T1 Logical Lines
Default: Flags
Options: Flags
| Idles
Function: Specifies the interframe time-fill pattern for transmission across this circuit.
Flags selects an 0x7E pattern (0 1 1 1 1 1 1 0); Idles selects an 0xFF pattern (1 1
1 1 1 1 1 1).
Instructions: Set the line interframe time-fill character.
MIB Object ID: 1.3.6.1.4.1.18.3.4.9.6.1.19
Parameter: CRC Size
Path: Configured MCE1 or MCT1 Connector > MCE1/T1 Logical Lines
Default: 16 bit CRC
Options: 32 bit CRC
| 16 bit CRC
Function: Specifies the Cyclic Redundancy Check (CRC) type. With 16-bit CRC, the
router appends a 16-bit CRC to the transmitted frames and performs a 16-bit
CRC on received frames. With 32-bit CRC, the router appends a 32-bit CRC to
transmitted frames and performs a 32-bit CRC on received frames.
Instructions: Set the CRC size.
MIB Object ID: 1.3.6.1.4.1.18.3.4.9.6.1.20
Parameter: MTU Size (bytes)
Path: Configured MCE1 or MCT1 Connector > MCE1/T1 Logical Lines
Default: 1600 bytes
Options: 3 to 4608 bytes
Function: Specifies the transmit/receive buffer size (Maximum Transmission Unit) to
configure the largest frame that the router can transmit or receive across this
MCE1 port. The router discards frames larger than this value.
Instructions: Enter a value in the range 3 to 4608 bytes.
