70 Port Block Functions (Continued)

73 PORT STATUS REGISTER FUNCTIONS

Each RIC port has its own status register In addition to

providing status concerning the port and its network seg-

ment the register allows the following operations to be per-

formed upon the port

1 Port disable

2 Link Disable

3 Partition reconnection

4 Selection between normal and reduced squelch levels

Note that the link disable and port disable functions are mu-

tually exclusive functions ie disabling link does not affect

receiving and transmitting fromto that port and disabling a

port does not disable link

When a port is disabled packet transmission and reception

between the port’s segment and the rest of the network is

prevented

TLF11096 – 19
