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.
