3Com (3C18140A) Repeater

Repeater modules provide all the standard functions within an 802.3 Repeater. Frames are regenerated and retimed, allowing them to be transmitted further than the maximum length of a single cable segment. Fragment extension extends undersized collision fragments so that they can be detected by devices throughout the network. Jabber lock-up protection prevents transceivers attached to the MSH from locking up in the case of devices jabbering (jabbering is the uncontrolled transmission of oversized frames to the network). ??Modules provide protection from faults such as cable breaks and faulty connectors, which would halt all network communication. In these circumstances, the segment in which the fault occurs is isolated by partitioning it from the rest of the network after 32 collisions.??Modules can be isolated from the backplane and therefore all other modules in the MSH chassis via a configurable jumper. In Isolation mode, a module acts as a repeater for only the segments attached... Minimize
