Comparison of RFC 1407 and the DL3100 Statistics Menu
Table 5-2 compares RFC 1407 to the DL3100 Statistics Menu.
Notes on RFC1407 MIB far end statistics support
The RFC1407 MIB module contains three groups:
¥ DS3/E3 Near End Group (mandatory),
¥ DS3 Far End Group (optional), and
¥ DS3 Fractional Group (optional).
The DS3 Far End Group is a new group. This group contains conÞguration
information and statistics that are collected from the far end DS3/E3
interface. Presently, the Far End Group may only be implemented by DS3
systems that use C-bit Parity or SYNTRAN.
The DS3 Far End statistics are various statistics collected from the far end
block error code within the C-bits.
