In this topology the lines between each RC3000 are assistant network management
channels, and for normal network management there must be network management
topology configuration as follows:
RC3000 A: double E1 channel direction RC3000 B: single E1 channel direction
RC3000 C: single E1 channel direction RC3000 D: four E1 channel direction
RC3000 E: single E1 channel direction RC3000 F: single E1 channel direction
Rules for network management topology: the number of network management channels
decides the number of E1 direction, and configuration of E1 direction must start from 1
E1.
b. Network management cascade:
Local and remote network management channel connection can be realized through
LINK UP and LINK DOWN interfaces on RC3000 as in figure 20:
There are three RC3000 networks: RC3000 A and RC3000 B connected through E1
cable, RC3000 C and RC3000 D connected through E1 cable, RC3000 E and RC3000 F
connected through E1 cable; connect RC3000A and RC3000C through cascade cable,
RC3000B and RC3000E through cascade cable, and set the second bits of A, C, E’s
DIP-switches ON, then local and remote network management channel connection can
be realized through LINK UP and LINK DOWN interfaces
